This article aims to scientifically demonstrate that living beings and planets like the Earth, stars like the Sun and the Universe we live in will come to an end due to entropy because they will evolve over time to a state of disorder. Entropy is commonly associated with the degree of disorder in a system. The greater the disorder of a thermodynamic system, the greater its entropy. All forms of life have a net increase in entropy. To sustain life, it is necessary to transfer energy to the living being. If you fail to do so, the organism soon dies and always tends towards the destruction of the order it had, that is, towards disorder or an increase in entropy. Planet Earth increases its entropy due to the increased exploitation of its resources, deforestation, pollution, among other sources of degradation. The greater this degradation, the greater the entropy of the planet, which could reach such a high stage that life on Earth will no longer be possible. The Sun's death will occur when it is in an advanced phase of its life and all its fuel, hydrogen, is consumed. The thermal death of the Universe will occur when it reaches its state of maximum entropy (state of thermodynamic equilibrium) and darkness reigns in the Universe, marking its "death". Based on the above, all living beings, all planets, all stars and the Universe, which constitute thermodynamic systems, will end when their respective entropies reach the maximum value. To avoid the end of human beings as a species, it is necessary to make scientific and technological advances that ensure human life outside Earth and identify the existence of parallel universes to open the possibility for human beings to survive the end of our Universe by heading to parallel universes.
THE LAW OF ENTROPY AND THE ACHIEVEMENT OF HUMAN BEING IMMORTALITY.pdfFaga1939
This article aims to analyze the possibilities of achieving human immortality in the face of the obstacle represented by the law of entropy that measures the degree of disorder in a system. Entropy in biological systems, for example, is explained when a living being, when performing work, part of the heat produced keeps its body warm, but a large part dissipates in the environment around it, causing a large fraction of the energy of its fuel sources are transformed into heat. The net effect of the original process (decrease in the entropy of the living being) and the transfer of energy (increase in entropy in the external environment) is a general increase in the entropy of the Universe. Everyone agrees that thanks to entropy, the disorder of life occurs, with galaxies sinking into black holes, stars turning into carbon dust, car and airplane engines wearing out and aging leading us to death. In June 2019, a team of scientists from the Technical University of Munich and the Max Planck Institute for Physics and Complex Systems announced that an exception to this universal rule had been found in the mysterious quantum world with the “quasi-particle” phenomenon that occurs in a series of endless cycles, making them, in fact, immortal. This fact continues to stimulate discussions about an ancient human desire: the immortality of the human body. In the past, man sought to overcome death through religions. In the contemporary era, people began to believe that it would be possible to overcome death through the use of science and technology. The year 2045 will mark the beginning of an era in which medicine will be able to offer humanity the possibility of living for a time never seen in history. We will be just a few steps away from immortality. Considering the speed of innovations, a person born in 2050 will have a 95% chance of living a thousand years. Will all this effort aimed at achieving immortality be able to overcome the forces imposed by the law of entropy? To what extent can the immortality of “quasi-particles” contribute to making human beings immortal? To what extent will science and technology contribute to the achievement of immortality for human beings?
Thermodynamics is the branch of physics that deals with the relationships between heat and other forms of energy. In particular, it describes how thermal energy is converted to and from other forms of energy and how it affects matter.

3. A deep understanding of thermodynamics illustrates why perpetual motion is impossible and why energy must be continually replenished to maintain order in systems.
1. Chemical reactions can be either exergonic or endergonic, with exergonic reactions releasing energy and endergonic reactions requiring energy.
2. The laws of thermodynamics state that energy is conserved but tends to dissipate such that entropy increases over time, making energy less usable.
3. The second law of thermodynamics explains that living organisms require a constant input of energy to maintain life functions against the natural increase in entropy.

This document discusses key concepts in thermodynamics and their applications in biophysics. It introduces biophysics as applying physics principles to biological systems. Thermodynamics provides a framework to understand energy transformations in living organisms. The three laws of thermodynamics - zeroth law regarding thermal equilibrium, first law of energy conservation, and second law of entropy increase - are explained. The third law is also introduced. Examples are given of how these laws apply to biological processes like cellular respiration, protein folding, and temperature regulation. Biological thermodynamics is defined as studying biochemical dynamics controlled by energy processes like ATP hydrolysis and enzyme kinetics.
Thermodynamics is the study of energy in living systems. The document discusses three main points:
1) It summarizes the first and second laws of thermodynamics as they apply to biological systems - the first law states that energy cannot be created or destroyed, only changed in form, while the second law states that entropy increases over time as energy is dissipated.
2) It explains how living cells take in energy and transform it into chemical or mechanical work through various energy coupling reactions, making all cells "energy parasites".
3) It discusses how thermodynamic concepts like Gibbs free energy, entropy, and thermal energy are relevant to understanding biochemical processes in cells and the flow of energy that maintains life.
Thermodynamic laws describe the flows and interchanges of heat, energy and matter.
Almost all chemical and biochemical processes are as a result of transformation of energy.
Laws can provide important insights into metabolism and bioenergetics.

Entropy in physics, biology and in thermodynamicsjoshiblog
Entropy is a measure of probability and the "disorder" of a system.
Disorder refers to is really the number of different microscopic states a system can be in, given that the system has a particular fixed composition, volume, energy, pressure, and temperature.
the exact definition is
Entropy = (Boltzmann's constant k) x logarithm of number of possible states
= k log(N).
The first law of thermodynamics defines the relationship between the various forms of energy present in a system (kinetic and potential), the work which the system performs and the transfer of heat.
We can imagine thermodynamic processes which conserve energy but which never occur in nature.
For example, if we bring a hot object into contact with a cold object, we observe that the hot object cools down and the cold object heats up until an equilibrium is reached. The transfer of heat goes from the hot object to the cold object.
According to the second law of thermodynamics, in any process that involves a cycle, the entropy of the system will either stay the same or increase. When the cyclic process is reversible then the entropy will not change. When the process is irreversible, then entropy will increases.
The second law states that there exists a useful state variable called entropy S. The change in entropy delta S is equal to the heat transfer delta Q divided by the temperature T.
delta S = delta Q / T
Order can be produced with an expenditure of energy, and the order associated with life on the earth is produced with the aid of energy from the sun.
For example, plants use energy from the sun in tiny energy factories called chloroplasts Using chlorophyll in the process called photosynthesis, they convert the sun's energy into storable form in ordered sugar molecules. In this way, carbon and water in a more disordered state are combined to form the more ordered sugar molecules.
In animal systems there are also small structures within the cells called mitochondria which use the energy stored in sugar molecules from food to form more highly ordered structures.

This document provides information about ecology notes on energy and material cycling in ecosystems. It discusses the key roles of energy and various biogeochemical cycles, including the carbon, nitrogen, water, oxygen, and phosphorus cycles. The three main points covered are:
1) Energy flows through ecosystems in a one-way path and is required by organisms but is lost as heat or low-temperature emissions. The laws of thermodynamics govern energy flow.
2) Biogeochemical cycles recirculate essential elements like carbon, nitrogen, water, oxygen, and phosphorus between organisms and the environment. These cycles are important for maintaining life.
3) Human activities can disrupt natural cycles, like increasing carbon dioxide levels
1. The document discusses metabolism and energy transformations in living organisms. It covers topics like metabolic pathways, ATP, the laws of thermodynamics, free energy, and exergonic and endergonic reactions.
2. Key points include that metabolic pathways convert energy from one form to another through chemical reactions, and that cellular respiration and photosynthesis involve exergonic and endergonic reactions, respectively.
3. The first and second laws of thermodynamics state that energy cannot be created or destroyed, and that entropy increases over time as energy is transferred or transformed.
Ecosystems maintain themselves through the cycling of energy and nutrients obtained from external sources like the sun. Primary producers like plants use photosynthesis to produce organic materials from solar energy, forming the base of the trophic structure. While primary producers absorb most energy from the sun, decomposers process large amounts of organic material and release more energy, making them more important than producers in terms of energy flow through the ecosystem.

1. Energy drives all life processes at the cellular level and exists in two forms: kinetic energy which is actively involved in work and potential energy which is stored for future use. Cells obtain energy through chemical reactions obeying the laws of thermodynamics.
2. Enzymes are protein catalysts that greatly increase the rate of chemical reactions in cells by lowering the activation energy required. Enzyme structure allows for specific binding of substrate molecules in the active site.
3. Factors like temperature and pH can affect enzyme shape and activity by disrupting bonds critical for structure and function. Cofactors and coenzymes are additional non-protein molecules that facilitate enzyme catalysis.
Thermodynamics describes the flow of energy in biological systems. Cells use ATP to store and transport chemical energy for metabolic reactions. ATP is regenerated by breaking down nutrients through oxidative phosphorylation, storing energy from food in ATP's phosphate bonds. Metabolism consists of anabolic and catabolic pathways which use ATP to drive the building up and breaking down of molecules. Biochemical pathways organize these reactions, and feedback inhibition regulates pathway activity based on product levels. Overall, thermodynamics governs how living things transform energy to carry out functions through intricate metabolic processes at the cellular level.
This document summarizes a basic biology practicum report on the influence of temperature on organism activity. It was conducted by a student named Jeny ayu hardiah ningrum in December 2011. The practicum involved observing the operculum movement frequency of goldfish (Cyprinus carpio) in warm water and cold water with ice cubes over 5 minutes to determine how temperature affects chemical reactions and activity in the body. The purpose was to compare oxygen usage speeds in different temperatures. The practicum aimed to provide knowledge on how temperature influences organism processes and help with fish care.

The document discusses entropy, the second law of thermodynamics, and their environmental impacts. It explains that entropy is a measure of disorder or randomness in a system that always increases over time according to the second law. This means that as energy is used, efficiency is lost, so perpetual motion machines are impossible and there is no free or clean energy. While humans can locally reduce entropy through technology, this globally increases entropy and pollution in the environment. Therefore, the best approach is to minimize consumption and waste.
Chemical energy stored by molecules can be released as heat
during chemical reactions when a fuel like methane, cooking
gas or coal burns in air. The chemical energy may also be
used to do mechanical work when a fuel burns in an engine
or to provide electrical energy through a galvanic cell like
dry cell. Thus, various forms of energy are interrelated and
under certain conditions, these may be transformed from
one form into another. The study of these energy
transformations forms the subject matter of thermodynamics.
The laws of thermodynamics deal with energy changes of
macroscopic systems involving a large number of molecules
rather than microscopic systems containing a few molecules.
Thermodynamics is not concerned about how and at what
rate these energy transformations are carried out, but is
based on initial and final states of a system undergoing the
change. Laws of thermodynamics apply only when a system
is in equilibrium or moves from one equilibrium state to
another equilibrium state.Chemical energy stored by molecules can be released as heat

This document discusses key aspects of ecosystem biodiversity, including:
1. The structure of ecosystems includes abiotic (non-living) components like soil, climate, and chemicals, as well as biotic (living) components like producers, consumers, and decomposers.
2. Energy flows through ecosystems via food chains and food webs from producers to various consumer levels, and is lost at each trophic level, resulting in less biomass at higher levels.
3. Ecological pyramids illustrate the trophic structure of ecosystems, showing decreasing numbers, biomass, or energy with increasing trophic level.
The document discusses thermodynamics in ecology. It explains that the sun provides the energy that drives photosynthesis, the most important chemical reaction. It introduces concepts like food chains, food webs, and how energy enters ecosystems. It defines thermodynamics as the study of how energy causes movement and changes with temperature, pressure and volume. It outlines the first law of thermodynamics that energy cannot be created or destroyed, just changed forms, and the second law that entropy increases and energy is lost as heat in all conversions. Finally, it states that life requires a continuous expenditure of energy.
Bioenergetics is the study of energy transformations that occur in living cells. It examines how cells acquire chemical energy from nutrients and transform that energy to power biological processes through reactions like oxidative phosphorylation. Adenosine triphosphate (ATP) acts as the main energy currency, being produced from energy sources and broken down to release energy for cellular work. Thermodynamic principles like the first and second laws govern these energy transformations, requiring a constant total energy while increasing entropy as energy is dissipated into less useful forms like heat.
This document provides an overview of homeostasis in the human body. Homeostasis refers to the body's ability to maintain stability and equilibrium by regulating physiological systems. This involves receptors that detect changes, a control center that processes information, and effectors that respond to restore conditions. Negative feedback mechanisms work to reverse changes, like increasing sweating to cool the body or accelerating breathing to expel more carbon dioxide. Together these homeostatic processes continually adjust the body's internal conditions to sustain life.
Ecosystems are made up of abiotic and biotic components that interact through energy flows and biogeochemical cycling. Energy from the sun enters ecosystems and is transferred between trophic levels through food webs, though less is available at each higher level. Elements cycle within ecosystems and their availability, determined by biogeochemical processes, can limit biological activity. Ecosystem function is controlled by both top-down predation and bottom-up nutrient availability.

Thermodynamics is the branch of physics that studies the effects of temperature, pressure, and volume changes on systems using statistics and particle motion analysis. It examines how energy moves and causes movement. The first law of thermodynamics states that energy is conserved; the second law is about entropy and how the entropy of isolated systems increases over time. The third law indicates that entropy reaches its minimum at absolute zero temperature. The human mind's design reflects the second law's influence, as its problem-solving logic evolved to cope with entropy constraints.
This document provides an outline of key topics in ecology, including elements of life, organic compounds, cells, energy laws, photosynthesis, respiration, ecosystems, food chains, ecological pyramids, and material cycles. It defines important terms and concepts and describes the flow of matter and energy through biological systems from the cellular to the ecosystem level.
Capitalism is a system that operates according to the principle of entropy because it presents the universal tendency to evolve into a growing disorder and self-destruction. This situation is evidenced by the downward trend of the profit rate of the United States, largest world economy which was 24% in 1950 and 13% in 2000 and reach a rate of profit equal to zero in 2059, as well as the fall in the rate of profit at historical cost of the fixed capital of US corporations which was 32% in 1947 and 13% in 2007 and will reach zero in 2048. It follows, therefore, that the world capitalist system would become infeasible made impossible between 2048 and 2059 because profit rates will be negative from the mid-twenty-first century. Neoliberalism by denying the regulation of the world capitalist system collaborates on bringing the system to self-destruction.
- Physical chemistry is the branch of chemistry that applies principles and methods of physics to chemical systems. It covers various topics including thermodynamics, kinetics, quantum chemistry, and spectroscopy.
- The four main branches of physical chemistry are thermodynamics, quantum chemistry, statistical mechanics, and kinetics. Thermodynamics studies heat and equilibrium properties, while kinetics examines reaction rates.
- The laws of thermodynamics govern energy transfer in chemical systems. The first law states that energy is conserved, while the second law says entropy increases over time as energy is dispersed.
COMMENT SURMONTER LES MENACES SUR LA GOUVERNABILITÉ DU GOUVERNEMENT LULA AU B...Faga1939
Cet article vise à présenter comment surmonter les menaces à la gouvernabilité du gouvernement Lula que représentent les difficultés à promouvoir le développement économique et social au Brésil et les actions antidémocratiques et antisociales promues par les extrémistes de droite enracinés dans le Congrès national et dans la société. La promotion du développement économique et social du Brésil a été entravée par la politique budgétaire de plafonnement des dépenses publiques imposée par le Congrès national, qui restreint les investissements publics et les politiques sociales, et par la politique monétaire de taux d'intérêt extrêmement élevés imposée par la Banque centrale, qui limite la croissance de l’économie nationale. Le gouvernement Lula est confronté aux menaces des extrémistes de droite retranchés au Congrès national en raison du fait qu'il ne dispose pas de majorité au Parlement, ce qui empêche le gouvernement fédéral de mettre en œuvre son projet national développementaliste, de répondre pleinement aux revendications sociales et d'éviter l'approbation du projets de loi rétrogrades et amendements constitutionnels rétrogrades. En d’autres termes, le gouvernement Lula n’est pas en mesure d’exercer sa gouvernabilité. Tous ces faits démontrent qu'il ne suffit pas d'élire un Président de la République engagé dans le progrès du pays pour mener à bien les changements économiques et sociaux requis. Outre l'élection d'un président progressiste, il est également nécessaire d'obtenir une majorité au Congrès national et dans les parlements étatiques et municipaux avec la création d'un large front et la mobilisation de la société civile pour élire le plus grand nombre possible de parlementaires progressistes engagés à les avancées politiques, économiques et sociales pour surmonter les obstacles qui entravent le développement du Brésil.
COMO SUPERAR AS AMEAÇAS À GOVERNABILIDADE DO GOVERNO LULA.pdfFaga1939
Este artigo tem por objetivo apresentar como superar as ameaças à governabilidade do governo Lula representadas pelas dificuldades de promover o desenvolvimento econômico e social do Brasil e pelas ações antidemocráticas e antissociais promovidas por extremistas de direita enquistados no Congresso Nacional e na sociedade. A promoção do desenvolvimento econômico e social do Brasil vem sendo dificultada pela política fiscal do teto de gastos públicos imposta pelo Congresso Nacional restritiva aos investimentos públicos e às políticas sociais e pela política monetária de juros extremamente elevados imposta pelo Banco Central restritiva ao crescimento da economia nacional. O governo Lula enfrenta ameaças de extremistas de direita enquistados no Congresso Nacional pelo fato de não ter maioria no parlamento que impede o governo federal de colocar em prática seu projeto nacional desenvolvimentista, atender as demandas sociais na plenitude e evitar a aprovação de projetos de lei retrógrados e de emendas constitucionais retrógradas. Em outras palavras, o governo Lula não está tendo condições de exercer a governabilidade. Todos estes fatos demonstram que que não basta eleger um presidente da República comprometido com o progresso do País para realizar as mudanças econômicas e sociais exigidas. Além de eleger um presidente progressista, é preciso, também, conquistar a maioria no Congresso Nacional e nos parlamentos estaduais e municipais com a constituição de uma frente ampla e com a mobilização da sociedade civil para eleger o maior número possível de parlamentares progressistas comprometidos com os avanços políticos, econômicos e sociais para superar os entraves que impedem o desenvolvimento do Brasil.

While humans can locally reduce entropy through technology, this globally increases entropy and pollution in the environment. Therefore, the best approach is to minimize consumption and waste.
Chemical energy stored by molecules can be released as heat
during chemical reactions when a fuel like methane, cooking
gas or coal burns in air. The chemical energy may also be
used to do mechanical work when a fuel burns in an engine
or to provide electrical energy through a galvanic cell like
dry cell. Thus, various forms of energy are interrelated and
under certain conditions, these may be transformed from
one form into another. The study of these energy
transformations forms the subject matter of thermodynamics.
The laws of thermodynamics deal with energy changes of
macroscopic systems involving a large number of molecules
rather than microscopic systems containing a few molecules.
Thermodynamics is not concerned about how and at what
rate these energy transformations are carried out, but is
based on initial and final states of a system undergoing the
change. Laws of thermodynamics apply only when a system
is in equilibrium or moves from one equilibrium state to
another equilibrium state.Chemical energy stored by molecules can be released as heat

This document discusses key aspects of ecosystem biodiversity, including:
1. The structure of ecosystems includes abiotic (non-living) components like soil, climate, and chemicals, as well as biotic (living) components like producers, consumers, and decomposers.
2. Energy flows through ecosystems via food chains and food webs from producers to various consumer levels, and is lost at each trophic level, resulting in less biomass at higher levels.
3. Ecological pyramids illustrate the trophic structure of ecosystems, showing decreasing numbers, biomass, or energy with increasing trophic level.
The document discusses thermodynamics in ecology. It explains that the sun provides the energy that drives photosynthesis, the most important chemical reaction. It introduces concepts like food chains, food webs, and how energy enters ecosystems. It defines thermodynamics as the study of how energy causes movement and changes with temperature, pressure and volume. It outlines the first law of thermodynamics that energy cannot be created or destroyed, just changed forms, and the second law that entropy increases and energy is lost as heat in all conversions. Finally, it states that life requires a continuous expenditure of energy.
Bioenergetics is the study of energy transformations that occur in living cells. It examines how cells acquire chemical energy from nutrients and transform that energy to power biological processes through reactions like oxidative phosphorylation. Adenosine triphosphate (ATP) acts as the main energy currency, being produced from energy sources and broken down to release energy for cellular work. Thermodynamic principles like the first and second laws govern these energy transformations, requiring a constant total energy while increasing entropy as energy is dissipated into less useful forms like heat.
This document provides an overview of homeostasis in the human body. Homeostasis refers to the body's ability to maintain stability and equilibrium by regulating physiological systems. This involves receptors that detect changes, a control center that processes information, and effectors that respond to restore conditions. Negative feedback mechanisms work to reverse changes, like increasing sweating to cool the body or accelerating breathing to expel more carbon dioxide. Together these homeostatic processes continually adjust the body's internal conditions to sustain life.
Ecosystems are made up of abiotic and biotic components that interact through energy flows and biogeochemical cycling. Energy from the sun enters ecosystems and is transferred between trophic levels through food webs, though less is available at each higher level. Elements cycle within ecosystems and their availability, determined by biogeochemical processes, can limit biological activity. Ecosystem function is controlled by both top-down predation and bottom-up nutrient availability.

Thermodynamics is the branch of physics that studies the effects of temperature, pressure, and volume changes on systems using statistics and particle motion analysis. It examines how energy moves and causes movement. The first law of thermodynamics states that energy is conserved; the second law is about entropy and how the entropy of isolated systems increases over time. The third law indicates that entropy reaches its minimum at absolute zero temperature. The human mind's design reflects the second law's influence, as its problem-solving logic evolved to cope with entropy constraints.
This document provides an outline of key topics in ecology, including elements of life, organic compounds, cells, energy laws, photosynthesis, respiration, ecosystems, food chains, ecological pyramids, and material cycles. It defines important terms and concepts and describes the flow of matter and energy through biological systems from the cellular to the ecosystem level.
Capitalism is a system that operates according to the principle of entropy because it presents the universal tendency to evolve into a growing disorder and self-destruction. This situation is evidenced by the downward trend of the profit rate of the United States, largest world economy which was 24% in 1950 and 13% in 2000 and reach a rate of profit equal to zero in 2059, as well as the fall in the rate of profit at historical cost of the fixed capital of US corporations which was 32% in 1947 and 13% in 2007 and will reach zero in 2048. It follows, therefore, that the world capitalist system would become infeasible made impossible between 2048 and 2059 because profit rates will be negative from the mid-twenty-first century. Neoliberalism by denying the regulation of the world capitalist system collaborates on bringing the system to self-destruction.
- Physical chemistry is the branch of chemistry that applies principles and methods of physics to chemical systems. It covers various topics including thermodynamics, kinetics, quantum chemistry, and spectroscopy.
- The four main branches of physical chemistry are thermodynamics, quantum chemistry, statistical mechanics, and kinetics. Thermodynamics studies heat and equilibrium properties, while kinetics examines reaction rates.
- The laws of thermodynamics govern energy transfer in chemical systems. The first law states that energy is conserved, while the second law says entropy increases over time as energy is dispersed.

Cet article vise à présenter comment surmonter les menaces à la gouvernabilité du gouvernement Lula que représentent les difficultés à promouvoir le développement économique et social au Brésil et les actions antidémocratiques et antisociales promues par les extrémistes de droite enracinés dans le Congrès national et dans la société. La promotion du développement économique et social du Brésil a été entravée par la politique budgétaire de plafonnement des dépenses publiques imposée par le Congrès national, qui restreint les investissements publics et les politiques sociales, et par la politique monétaire de taux d'intérêt extrêmement élevés imposée par la Banque centrale, qui limite la croissance de l’économie nationale. Le gouvernement Lula est confronté aux menaces des extrémistes de droite retranchés au Congrès national en raison du fait qu'il ne dispose pas de majorité au Parlement, ce qui empêche le gouvernement fédéral de mettre en œuvre son projet national développementaliste, de répondre pleinement aux revendications sociales et d'éviter l'approbation du projets de loi rétrogrades et amendements constitutionnels rétrogrades. En d’autres termes, le gouvernement Lula n’est pas en mesure d’exercer sa gouvernabilité. Tous ces faits démontrent qu'il ne suffit pas d'élire un Président de la République engagé dans le progrès du pays pour mener à bien les changements économiques et sociaux requis. Outre l'élection d'un président progressiste, il est également nécessaire d'obtenir une majorité au Congrès national et dans les parlements étatiques et municipaux avec la création d'un large front et la mobilisation de la société civile pour élire le plus grand nombre possible de parlementaires progressistes engagés à les avancées politiques, économiques et sociales pour surmonter les obstacles qui entravent le développement du Brésil.
COMO SUPERAR AS AMEAÇAS À GOVERNABILIDADE DO GOVERNO LULA.pdfFaga1939
Este artigo tem por objetivo apresentar como superar as ameaças à governabilidade do governo Lula representadas pelas dificuldades de promover o desenvolvimento econômico e social do Brasil e pelas ações antidemocráticas e antissociais promovidas por extremistas de direita enquistados no Congresso Nacional e na sociedade. A promoção do desenvolvimento econômico e social do Brasil vem sendo dificultada pela política fiscal do teto de gastos públicos imposta pelo Congresso Nacional restritiva aos investimentos públicos e às políticas sociais e pela política monetária de juros extremamente elevados imposta pelo Banco Central restritiva ao crescimento da economia nacional. O governo Lula enfrenta ameaças de extremistas de direita enquistados no Congresso Nacional pelo fato de não ter maioria no parlamento que impede o governo federal de colocar em prática seu projeto nacional desenvolvimentista, atender as demandas sociais na plenitude e evitar a aprovação de projetos de lei retrógrados e de emendas constitucionais retrógradas. Em outras palavras, o governo Lula não está tendo condições de exercer a governabilidade. Todos estes fatos demonstram que que não basta eleger um presidente da República comprometido com o progresso do País para realizar as mudanças econômicas e sociais exigidas. Além de eleger um presidente progressista, é preciso, também, conquistar a maioria no Congresso Nacional e nos parlamentos estaduais e municipais com a constituição de uma frente ampla e com a mobilização da sociedade civil para eleger o maior número possível de parlamentares progressistas comprometidos com os avanços políticos, econômicos e sociais para superar os entraves que impedem o desenvolvimento do Brasil.
L’EFFONDREMENT DE LA MONDIALISATION CONTEMPORAINE ET L’AVENIR DE L’ÉCONOMIE M...Faga1939
Cet article vise à démontrer que la mondialisation contemporaine se dirige rapidement vers l’effondrement et à proposer de nouvelles orientations pour l’avenir de l’économie mondiale. Les signes de l'effondrement de la mondialisation économique et financière contemporaine apparaissaient déjà dès 2010 lorsque le rapport entre les exportations mondiales et le PIB mondial a chuté d'environ 12 %, un déclin jamais vu depuis les années 1970. Les signes de l’effondrement de la mondialisation contemporaine se manifeste également par la tendance à la baisse du taux de profit mondial, la baisse du taux de profit aux États-Unis et la baisse du taux de croissance du produit mondial brut. Si la tendance à la baisse du taux de profit se maintient, le taux de profit du système capitaliste mondial tendrait vers zéro en 2037. Si la tendance à la baisse du taux de profit aux États-Unis se maintient, le taux de profit aux États-Unis atteindra valeur nulle en 2043. Si la tendance à la baisse du taux de croissance du produit mondial brut se maintient, ce taux atteindra la valeur zéro en 2053. Ces estimations ont été obtenues sur la base de la méthode statistique des moindres carrés. Il est conclu que le système capitaliste mondial deviendra non viable au milieu du 21e siècle (2037, 2043 ou 2053), lorsque le processus d’accumulation du capital cessera et que les taux de profit et de croissance de l’économie mondiale atteindront une valeur nulle. Face à l’échec et à l’effondrement de la mondialisation contemporaine, il est urgent de construire une nouvelle mondialisation avec un keynésianisme mondial et un gouvernement mondial pour ordonner l’économie mondiale. La politique économique keynésienne adoptée dans chaque pays et au niveau mondial et l'existence d'un gouvernement mondial sont les solutions pour faire face à l'effondrement de la mondialisation contemporaine et éliminer le chaos qui caractérise l'économie mondiale. Face à l’échec du néolibéralisme et à son incapacité à faire face à la crise mondiale du capitalisme, le keynésianisme pourrait être la solution à condition qu’il soit appliqué dans chaque pays et à l’échelle mondiale, c’est-à-dire qu’il opère dans la planification économique, et pas seulement au niveau national pour obtenir la stabilité économique et le plein emploi des facteurs dans chaque pays, mais aussi au niveau mondial pour éliminer le chaos économique mondial qui prévaut actuellement avec le néolibéralisme. Avec le keynésianisme dans chaque pays et à l’échelle mondiale, il y aurait une coordination des politiques économiques keynésiennes au niveau planétaire qui ne pourrait être réalisée qu’avec l’existence d’un gouvernement mondial.

ENERGY PRODUCTION AND CONSUMPTION FROM PREHISTORY TO THE CONTEMPORARY ERA AND...Faga1939
This article aims to present how the evolution of energy consumption and production occurred from prehistoric times to current times, as well as proposing the future of energy required for the world. From prehistory until the 18th century, the use of renewable energy sources such as wood, wind and hydraulic energy predominated. From the 18th century until the contemporary era, fossil fuels predominated with coal and oil, but their use will probably come to an end from the 21st century onwards to avoid catastrophic global climate change resulting from their use by emitting greenhouse gases responsible for the global warming. With the end of the era of fossil fuels will come the era of renewable energy sources when the use of hydroelectric energy, solar energy, wind energy, tidal energy, wave energy, geothermal energy, biomass energy and hydrogen energy will prevail. There is no doubt that human activities on Earth cause changes in the environment in which we live. Many of these environmental impacts come from the generation, handling and use of energy using fossil fuels. The main reason for the existence of these environmental impacts lies in the fact that global consumption of primary energy from non-renewable sources (oil, coal, natural gas and nuclear) corresponds to approximately 88% of the total, with only 12% coming from renewable sources. Regardless of the various solutions that may be adopted to eliminate or mitigate the causes of the greenhouse effect, the most important action is, without a doubt, the adoption of measures that contribute to the elimination or reduction of the consumption of fossil fuels in energy production, as well as as well as for its more efficient use in transport, industry, agriculture and cities (residences and commerce), given that the use and production of energy are responsible for 57% of greenhouse gases emitted by human activity. In this sense, it is essential to implement a sustainable energy system in the world. In a sustainable energy system, the global energy matrix should only rely on clean and renewable energy sources (hydroelectric, solar, wind, hydrogen, geothermal, tidal, wave and biomass), and should therefore not rely on the use fossil fuels (oil, coal and natural gas).
PRODUÇÃO E CONSUMO DE ENERGIA DA PRÉ-HISTÓRIA À ERA CONTEMPORÂNEA E SUA EVOLU...Faga1939
Este artigo tem por objetivo apresentar como ocorreu a evolução do consumo e da produção de energia desde a pré-história até os tempos atuais, bem como propor o futuro da energia requerido para o mundo. Da pré-história até o século XVIII predominou o uso de fontes renováveis de energia como a madeira, o vento e a energia hidráulica. Do século XVIII até a era contemporânea, os combustíveis fósseis predominaram com o carvão e o petróleo, mas seu uso chegará ao fim provavelmente a partir do século XXI para evitar a mudança climática catastrófica global resultante de sua utilização ao emitir gases do efeito estufa responsáveis pelo aquecimento global. Com o fim da era dos combustíveis fósseis virá a era das fontes renováveis de energia quando prevalecerá a utilização da energia hidrelétrica, energia solar, energia eólica, energia das marés, energia das ondas, energia geotérmica, energia da biomassa e energia do hidrogênio. Não existem dúvidas de que as atividades humanas sobre a Terra provocam alterações no meio ambiente em que vivemos. Muitos destes impactos ambientais são provenientes da geração, manuseio e uso da energia com o uso de combustíveis fósseis. A principal razão para a existência desses impactos ambientais reside no fato de que o consumo mundial de energia primária proveniente de fontes não renováveis (petróleo, carvão, gás natural e nuclear) corresponde a aproximadamente 88% do total, cabendo apenas 12% às fontes renováveis. Independentemente das várias soluções que venham a ser adotadas para eliminar ou mitigar as causas do efeito estufa, a mais importante ação é, sem dúvidas, a adoção de medidas que contribuam para a eliminação ou redução do consumo de combustíveis fósseis na produção de energia, bem como para seu uso mais eficiente nos transportes, na indústria, na agropecuária e nas cidades (residências e comércio), haja vista que o uso e a produção de energia são responsáveis por 57% dos gases de estufa emitidos pela atividade humana. Neste sentido, é imprescindível a implantação de um sistema de energia sustentável no mundo. Em um sistema de energia sustentável, a matriz energética mundial só deveria contar com fontes de energia limpa e renováveis (hidroelétrica, solar, eólica, hidrogênio, geotérmica, das marés, das ondas e biomassa), não devendo contar, portanto, com o uso dos combustíveis fósseis (petróleo, carvão e gás natural).
LA LOI DE L'ENTROPIE ET LA CONQUÊTE DE L'IMMORTALITÉ DE L'ÊTRE HUMAIN.pdfFaga1939
Cet article vise à analyser les possibilités d'atteindre l'immortalité humaine face à l'obstacle que représente la loi de l'entropie qui mesure le degré de désordre dans un système. L'entropie dans les systèmes biologiques, par exemple, s'explique lorsqu'un être vivant, lorsqu'il effectue un travail, une partie de la chaleur produite maintient son corps au chaud, mais une grande partie se dissipe dans l'environnement qui l'entoure, provoquant une grande fraction de l’énergie provenant de ses sources de combustible à transformer en chaleur. L'effet net du processus originel (diminution de l'entropie de l'être vivant) et du transfert d'énergie (augmentation de l'entropie dans l'environnement extérieur) est une augmentation générale de l'entropie de l'Univers. Tout le monde s’accorde à dire que grâce à l’entropie, le désordre de la vie se produit, les galaxies s’enfonçant dans des trous noirs, les étoiles se transformant en poussière de carbone, les moteurs de voitures et d’avions s’usant et vieillissant nous conduisant à la mort. En juin 2019, une équipe de scientifiques de l'Université technique de Munich et de l'Institut Max Planck de physique et de systèmes complexes a annoncé qu'une exception à cette règle universelle avait été trouvée dans le mystérieux monde quantique avec le phénomène de « quasi-particule » qui se produit. dans une série de cycles sans fin, les rendant en fait immortels. Ce fait continue de stimuler les discussions sur un ancien désir humain : l’immortalité du corps humain. Dans le passé, l’homme cherchait à vaincre la mort à travers les religions. À l’époque contemporaine, les gens ont commencé à croire qu’il serait possible de vaincre la mort grâce à l’utilisation de la science et de la technologie. L’année 2045 marquera le début d’une ère dans laquelle la médecine pourra offrir à l’humanité la possibilité de vivre une époque jamais vue dans l’histoire. Nous ne serons qu’à quelques pas de l’immortalité. Compte tenu de la rapidité des innovations, une personne née en 2050 aura 95 % de chances de vivre mille ans. Tous ces efforts visant à atteindre l’immortalité parviendront-ils à vaincre les forces imposées par la loi de l’entropie ? Dans quelle mesure l’immortalité des « quasi-particules » peut-elle contribuer à rendre les êtres humains immortels ? Dans quelle mesure la science et la technologie contribueront-elles à l’obtention de l’immortalité des êtres humains ?
A LEI DA ENTROPIA E A CONQUISTA DA IMORTALIDADE DO SER HUMANO.pdfFaga1939
Este artigo tem por objetivo analisar as possibilidades de conquista da imortalidade do ser humano diante do obstáculo representado pela lei da entropia que mede o grau de desordem de um sistema. A entropia nos sistemas biológicos, por exemplo, se explica quando o ser vivo, ao realizar trabalho, parte do calor produzido conserva seu corpo aquecido, mas uma grande parte se dissipa no ambiente a seu redor, fazendo com que uma grande fração da energia de suas fontes de combustíveis seja transformada em calor. O efeito líquido do processo original (diminuição da entropia do ser vivo) e a transferência de energia (aumento de entropia no meio exterior) é um aumento geral na entropia do Universo. Todos concordam que graças à entropia, ocorre a desordem da vida, com as galáxias afundando em buracos negros, as estrelas virando poeira de carbono, motores de carros e aviões se desgastando e o envelhecimento nos encaminhando à morte. Em junho de 2019, uma equipe de cientistas da Universidade Técnica de Munique e do Instituto Max Planck de Física e Sistemas Complexos anunciou que foi encontrada uma exceção à esta regra universal no misterioso mundo quântico com o fenômeno das “quase-partículas” que ocorre numa série de ciclos intermináveis, tornando-as, de fato, imortais. O fato não deixa de estimular discussões sobre um milenar desejo humano: a imortalidade do corpo humano. No passado, o homem procurava superar a morte através das religiões. Na era contemporânea, passou-se a acreditar que seria possível vencer a morte com o uso da ciência e da tecnologia. O ano de 2045 marcará o início de uma era em que a medicina poderá oferecer à humanidade a possibilidade de viver por um tempo jamais visto na história. Estaremos a poucos passos da imortalidade. Considerando a rapidez das inovações, uma pessoa nascida em 2050 terá 95% de chance de viver mil anos. Todo este esforço voltado para a conquista da imortalidade será capaz de vencer as forças impostas pela lei da entropia? Até que ponto a imortalidade das “quase-partículas” poderá contribuir para tornar os seres humanos imortais? Até que ponto a ciência e a tecnologia contribuirão para a conquista da imortalidade dos seres humanos?
PEACE BETWEEN ISRAEL AND PALESTINE REQUIRES EXTREMISTS OUT OF POWER AND RESTR...Faga1939
This article aims to demonstrate the need for Israeli and Palestinian extremists to be removed from power and for the UN to be restructured so that there is peace between Israel and Palestine. The construction of peace can only happen in the Palestine region if the Jewish people in Israel and throughout the world, as well as the Palestinians, politically repel the extremists who exercise power in their territories and establish governments that seek conciliation between the Jewish and Palestinian peoples. It can be said that there is only one solution to the conflict between Palestine and Israel: on the one hand, Israel needs to accept the constitution of the Palestinian State, seek a fair and negotiated solution regarding Jerusalem and the fate of Palestinian refugees and end the settlements Jews in the West Bank and, on the other, Palestinians need to recognize the State of Israel because neither Palestinians nor Israelis can impose their will on each other. Neither the right-wing extremists who govern Israel nor the Palestinian extremist groups will be able to impose their will by force of arms in Palestine. It is unlikely that the conflict between Palestinians and Jews will be resolved today because existing international institutions are not capable of building a negotiated solution to the conflict between these two peoples and between Israel, Iran and the Arab countries. This means that there is an urgent need to restructure the international system to resolve the conflict between Israel and Palestine, between Russia and Ukraine and all international conflicts that may occur in the future. The time has come for humanity to promote the construction of world peace and to exercise control over its destiny. To achieve these objectives, it is urgent to restructure the UN with a view to transforming it into a democratic government of the world that constitutes the only means of survival for the human species.
PAZ ENTRE ISRAEL E PALESTINA EXIGE EXTREMISTAS FORA DO PODER E REESTRUTURAÇÃO...Faga1939
Este artigo tem por objetivo demonstrar a necessidade de que extremistas israelenses e palestinos sejam colocados fora do poder e haja a reestruturação da ONU para que haja paz entre Israel e Palestina. A construção da paz só poderá acontecer na região da Palestina se o povo judeu em Israel e no mundo inteiro, bem como os palestinos repelirem politicamente os extremistas que exercem o poder em seus territórios e constituírem governos que busquem a conciliação entre os povos judeu e palestino. Pode-se afirmar que só há uma solução para o conflito entre Palestina e Israel: de um lado, Israel precisa aceitar a constituição do Estado palestino, buscar uma solução justa e negociada sobre Jerusalém e sobre o destino de refugiados palestinos e acabar com os assentamentos judeus na Cisjordânia e, de outro, os palestinos precisam reconhecer o Estado de Israel porque nem palestinos nem israelenses podem impor sua vontade um ao outro. Nem os extremistas de direita que governam Israel nem os grupos extremistas palestinos terão condições de impor sua vontade pela força das armas na Palestina. É pouco provável que o conflito entre palestinos e judeus seja solucionado na atualidade porque as instituições internacionais existentes não são capazes de construir uma saída negociada para o conflito entre estes dois povos e entre Israel, o Irã e os países árabes. Isto significa dizer que urge a reestruturação do sistema internacional para solucionar o conflito entre Israel e Palestina, entre Rússia e Ucrânia e todos os conflitos internacionais que venham a ocorrer no futuro. É chegada a hora da humanidade promover a construção da paz mundial e de exercer o controle de seu destino. Para alcançar estes objetivos, urge a reestruturação da ONU visando transformá-la em um governo democrático do mundo que se constitui no único meio de sobrevivência da espécie humana.

HOW TO PLAN CITIES TO COPE WITH EXTREME WEATHER EVENTS.pdfFaga1939
This article aims to present what and how to do to promote cities planning capable of facing extreme weather events. Floods have been recurring in cities in several countries around the world, including Brazil. There is a drastic change in the Earth's climate thanks to global warming, which is contributing to the occurrence of floods in cities that are recurring in an increasingly catastrophic way in their effects. The floods that devastated some cities in western and southern Germany, Henan in China and London in England in 2021 and, currently, in Rio Grande do Sul demonstrate the vulnerability of highly populated areas to catastrophic floods. Water-related disasters caused worldwide losses of US$306 billion between 1980 and 2016. To cope with extreme weather events in cities, flood control must be carried out, which concerns all methods used to reduce or prevent the harmful effects of water action. Structural measures must be adopted with engineering works aimed at correcting and/or preventing problems arising from floods and non-structural measures which are those that seek to prevent and/or reduce the damage and consequences of floods, not through engineering works, but through the introduction of standards, regulations and programs that aim, for example, to regulate land use and occupation, implementation of alert systems and public awareness. The municipal government plays a fundamental role in preventing flooding, floods and floods in cities. To this end, a municipal development master plan must be drawn up that includes, among other measures, the adoption of solutions to minimize or eliminate the risks faced by the population, the systematic identification of risk areas in order to establish population settlement rules. Three bodies are essential in flood prevention actions in a municipality: 1) the municipal civil defense body; 2) the body responsible for the meteorological service responsible for reporting the climate forecast for the city and/or region; and, 3) community civil defense centers, which are people who work voluntarily in civil defense activities.
COMO PLANEJAR AS CIDADES PARA ENFRENTAR EVENTOS CLIMÁTICOS EXTREMOS.pdfFaga1939
Este artigo tem por objetivo apresentar o que e como fazer para promover o planejamento das cidades capaz de enfrentar eventos climáticos extremos. Tem sido recorrente a ocorrência de inundações nas cidades em vários países do mundo, inclusive no Brasil. Está havendo uma mudança drástica no clima da Terra graças ao aquecimento global que está contribuindo para a ocorrência de inundações nas cidades que se repetem de forma cada vez mais catastrófica em seus efeitos. As inundações que devastaram algumas cidades do oeste e do sul da Alemanha, Henan na China e Londres na Inglaterra em 2021 e, no momento, no Rio Grande do Sul demonstram a vulnerabilidade de áreas altamente populosas a enchentes catastróficas. Os desastres relacionados com a água causaram perdas mundiais de US$ 306 bilhões entre 1980 e 2016. Para fazer frente a eventos climáticos extremos nas cidades, é preciso que seja realizado o controle de inundações que diz respeito a todos os métodos usados para reduzir ou impedir os efeitos prejudiciais da ação das águas. Devem ser adotadas medidas estruturais com obras de engenharia visando a correção e / ou prevenção de problemas decorrentes de inundações e medidas não estruturais que são aquelas que buscam prevenir e / ou reduzir os danos e consequências das inundações, não por meio de obras de engenharia, mas pela introdução de normas, regulamentos e programas que visam, por exemplo, disciplinar o uso e ocupação do solo, implementação de sistemas de alerta e conscientização da população. A prefeitura municipal tem um papel fundamental no sentido de evitar alagamentos, enchentes e inundações nas cidades. Para tanto, deve elaborar um plano diretor de desenvolvimento municipal que contemple, entre outras medidas, a adoção de soluções para minimizar ou eliminar os riscos enfrentados pela população, a identificação sistemática de áreas de risco a fim de estabelecer regras de assentamento da população. Três órgãos são essenciais nas ações de prevenção a enchentes em um município: 1) o órgão municipal de defesa civil; 2) o órgão responsável pelo serviço de meteorologia responsável por informar a previsão do clima da cidade e/ou região; e, 3) os núcleos comunitários de defesa civil, que são pessoas que trabalham de forma voluntária nas atividades de defesa civil.

Le premier défi, d'ordre économique, est représenté par les obstacles qui existent avec la politique de plafonnement des dépenses, malgré la flexibilité offerte par le cadre budgétaire et l'existence d'une Banque centrale indépendante, qui rendent le gouvernement brésilien incapable de coordonner ses politiques monétaires et fiscales, réaliser des investissements publics dans l'expansion de l'économie et obtenir la stabilité macroéconomique et, le deuxième défi, de nature politique, est représenté par les obstacles existant au Congrès national du fait qu'il ne dispose pas de majorité au parlement, ce qui empêche le gouvernement fédéral de mettre en pratique son projet de développement national et de répondre pleinement aux exigences sociales. Pour que les forces progressistes brésiliennes puissent réélire le président Lula lors des élections présidentielles de 2026 et obtenir une majorité parlementaire au Congrès national engagé en faveur du progrès politique, économique et social, le gouvernement Lula devra réussir sur le front économique, en promouvant l'expansion du l'économie, en augmentant de manière significative en générant des emplois et des revenus, en maîtrisant l'inflation et en répondant au maximum aux revendications sociales qui profitent avant tout aux populations mal desservies du pays. Les forces progressistes du Brésil doivent s'engager, dès les élections municipales de 2024, à élire le nombre maximum de maires et de conseillers engagés dans les avancées politiques, économiques et sociales du Brésil. Telles sont les conditions pour empêcher, en 2026, les extrémistes de droite de reconquérir la présidence de la République, d’élargir leur participation aux gouvernements des États et au Congrès national et de mettre en pratique leur infâme projet antisocial et antinational.
THE OBSTACLES THAT IMPEDE THE DEVELOPMENT OF BRAZIL IN THE CONTEMPORARY ERA A...Faga1939
This article aims to demonstrate that the Lula government is faced with two major challenges in its effort to promote Brazil's economic and social development. The first challenge, of an economic nature, is represented by the obstacles that exist with the spending cap policy, despite the flexibility provided by the fiscal framework and the existence of an independent Central Bank, which make the Brazilian government unable to coordinate its fiscal and monetary policies, make public investments in the expansion of the economy and obtain macroeconomic stability and, the second challenge, of a political nature, is represented by the obstacles existing in the National Congress due to the fact that it does not have a majority in parliament, which prevents the federal government from putting its national developmental project into practice and fully meet social demands. For Brazil's progressive forces to re-elect President Lula in the 2026 presidential elections and obtain a parliamentary majority in the National Congress committed to political, economic and social advances, the Lula government will have to be successful on the economic front, promoting the expansion of the economy, increasing significantly generating jobs and income, keeping inflation under control and meeting the maximum social demands that benefit, above all, the country's underserved populations. Brazil's progressive forces need to commit, starting from the 2024 municipal elections, towards to elect the maximum number of mayors and councilors committed to Brazil's political, economic and social advances. These are the conditions to prevent, in 2026, right-wing extremists from regaining the Presidency of the Republic, expanding their participation in state governments and the National Congress and putting their nefarious anti-social and anti-national project into practice.
L'ÉVOLUTION DE L'ÉDUCATION AU BRÉSIL À TRAVERS L'HISTOIRE ET LES EXIGENCES DE...Faga1939
Cet article vise à présenter l’évolution de l’éducation au Brésil à travers l’histoire et les exigences de son développement futur. De 1500 jusqu'au XIXe siècle, l'éducation brésilienne s'est concentrée exclusivement sur la formation des classes supérieures, dans le but de les préparer aux activités politico-bureaucratiques et aux professions libérales, presque toujours en charge ou sous l'influence de l'initiative religieuse privée. La relation ombilicale entre l'Église catholique et la puissance coloniale portugaise s'est maintenue au Brésil même après son indépendance en 1822 pendant la période impériale et a pris fin avec la Proclamation de la République avec le divorce officiel entre l'Église et l'État. Au niveau des politiques publiques, plusieurs tentatives de réforme éducative de la part du gouvernement central républicain ont fini par perpétuer le modèle éducatif hérité de la période coloniale. La première LDB (Lei de Diretrizes e Bases da Educação Brasileira) de l’histoire de l’éducation brésilienne n’a pas brisé le binôme d’élitisme et d’exclusion qui s’était manifesté dans l’éducation brésilienne depuis la période coloniale. La LDB de 1961 a permis la cohabitation entre écoles publiques et privées. Cette situation éducative en vigueur au Brésil dans la seconde moitié du XXe siècle a suscité une critique acerbe de la part de Paulo Freire. En 1982, des projets éducatifs alternatifs à l'enseignement technique imposé par la dictature militaire ont émergé, comme ce qui s'est passé à Rio de Janeiro sous le gouvernement de Leonel Brizola, qui a mis en œuvre les soi-disant CIEP (Centres intégrés d'éducation publique), qui étaient des écoles à temps plein. Mais ces expériences éducatives adoptées de manière autonome et conformément aux corrélations de forces qui s’établissaient entre les tendances pédagogiques existantes étaient destinées à être de courte durée, comme cela s’est effectivement produit. Avec la fin de la dictature militaire au Brésil, la dernière décennie du XXe siècle a été marquée par l'adoption du modèle économique néolibéral qui a porté préjudice aux politiques publiques, notamment éducatives, car il a permis la croissance du secteur privé, principalement dans le contexte de l'enseignement supérieur, tandis que dans les écoles publiques, l'enseignement est devenu encore plus inefficace, une situation qui perdure aujourd'hui. Mais aujourd'hui, l'exclusion des classes populaires a eu lieu parce que l'école publique ne garantit pas l'apprentissage effectif des connaissances essentielles requises par la société brésilienne. De ce qui précède, on peut conclure qu’il reste encore une tâche majeure à accomplir pour la société brésilienne contemporaine : la consolidation effective d’écoles publiques, laïques et de qualité pour tous. À l'époque contemporaine, il est urgent de promouvoir une révolution dans le système éducatif brésilien, ce qui est devenu nécessaire parce que les mauvaises performances du système éducatif brésilien.
THE EVOLUTION OF EDUCATION IN BRAZIL THROUGHOUT HISTORY AND THE REQUIREMENTS ...Faga1939
This article aims to present the evolution of education in Brazil throughout history and the requirements for its future development. From 1500 until the 19th century, Brazilian education focused exclusively on training the upper classes, with the aim of preparing them for political-bureaucratic activities and liberal professions, almost always in charge of or under the influence of private religious initiative. The umbilical relationship between the Catholic Church and the Portuguese colonial power was maintained in Brazil even after its independence in 1822 during the imperial period and came to an end with the Proclamation of the Republic when there was an official divorce between Church and State. At the level of public policies, there were several attempts at educational reform by the republican central government that ended up perpetuating the educational model inherited from the colonial period. The first LDB (Lei de Diretrizes e Bases da Educação Brasileira) in the history of Brazilian education did not break the binomial of elitism and exclusion that had manifested itself in Brazilian education since the colonial period. The LDB of 1961 made it possible for public and private schools to cohabit. This educational situation in force in Brazil in the second half of the 20th century had a scathing critic in Paulo Freire. In 1982, alternative educational projects emerged to the technical education imposed by the military dictatorship, such as what occurred in Rio de Janeiro during the government of Leonel Brizola, which implemented the so-called CIEPs (Integrated Centers for Public Education), which were full-time schools. But these educational experiences adopted autonomously and in accordance with the correlations of forces that were established between existing pedagogical trends were destined to be short-lived, as in fact happened. With the end of the military dictatorship in Brazil, the last decade of the 20th century was marked by the adoption of the neoliberal economic model that harmed public policies, in particular education, as it allowed the growth of the private sector, mainly in the context of higher education, while In public schools, teaching became even more inefficient, a situation that continues today. Now, however, the exclusion of the popular classes took place because the State school does not guarantee the effective learning of the essential knowledge required by Brazilian society. From the above, it can be concluded that there is still a major task to be resolved by contemporary Brazilian society: the effective consolidation of state, public, secular and quality schools for all. In the contemporary era, there is an urgent need to promote a revolution in Brazil's education system, which has become necessary because the poor performance of Brazil's education system results, among other factors, above all from insufficient investments in Brazilian education.
A EVOLUÇÃO DA EDUCAÇÃO NO BRASIL AO LONGO DA HISTÓRIA E OS REQUISITOS PARA SE...Faga1939
Este artigo tem por objetivo apresentar a evolução da educação do Brasil ao longo da história e os requisitos para seu futuro desenvolvimento. De 1500 até o século XIX, a educação brasileira voltou-se exclusivamente à formação das camadas superiores, no intuito de prepará-las para as atividades político-burocráticas e das profissões liberais quase sempre a cargo ou sob a influência da iniciativa privada religiosa. A relação umbilical entre a Igreja Católica e o poder colonial português foi mantido no Brasil mesmo após sua independência ocorrida em 1822 durante o período imperial e chegou ao fim com a Proclamação da República quando houve o divórcio oficial entre Igreja e Estado. Ao nível das políticas públicas, houve várias tentativas de reforma educacional por parte do governo central republicano que acabaram por perpetuar o modelo educacional herdado do período colonial. A primeira LDB (Lei de Diretrizes e Bases da Educação Brasileira) da história da educação brasileira não rompeu o binômio do elitismo e da exclusão que se manifestava na educação brasileira desde o período colonial. A LDB de 1961 possibilitou a coabitação da escola pública e da particular. Esta situação educacional vigente no Brasil da segunda metade do século XX teve em Paulo Freire um crítico contundente. Em 1982, surgiram projetos educacionais alternativos ao ensino tecnicista imposto pela ditadura militar, como o que ocorreu no Rio de Janeiro durante o governo de Leonel Brizola que implementou os chamados CIEPs (Centros Integrados de Educação Pública) que eram escolas de período integral. Mas essas experiências educacionais adotadas de forma autônoma e de acordo com as correlações de forças que se estabeleciam entre as tendências pedagógicas existentes estavam fadadas a ter vida curta como de fato aconteceu. Com o fim da ditadura militar no Brasil, a última década do século XX ficou marcada pela adoção do modelo econômico neoliberal que prejudicou as políticas públicas, em particular a educação, pois permitiu o crescimento do setor privado, principalmente no âmbito do ensino superior, enquanto na escola pública o ensino ficou ainda mais ineficiente, situação esta que se mantem até hoje. Agora, porém, a exclusão das classes populares se realizava porque a escola de Estado não garante a aprendizagem efetiva dos conhecimentos essenciais exigidos pela sociedade brasileira. Pelo exposto, conclui-se que ainda existe uma grande tarefa a ser resolvida pela sociedade brasileira contemporânea: a efetiva consolidação da escola de Estado, pública, laica e de qualidade para todos. Na era contemporânea, urge promover uma revolução no sistema de educação do Brasil, que se tornou necessária porque o péssimo desempenho do sistema de educação do Brasil resulta, entre outros fatores, sobretudo da insuficiência de investimentos na educação brasileira quando comparado com os investimentos em educação dos melhores sistemas de educação do mundo.

SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole⋆Sérgio Sacani
Context. The early-type galaxy SDSS J133519.91+072807.4 (hereafter SDSS1335+0728), which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Facility (ZTF) alert stream from December 2019 (as ZTF19acnskyy). This variability behaviour, coupled with the host-galaxy properties, suggests that SDSS1335+0728 hosts a ∼ 106M⊙ black hole (BH) that is currently in the process of ‘turning on’. Aims. We present a multi-wavelength photometric analysis and spectroscopic follow-up performed with the aim of better understanding the origin of the nuclear variations detected in SDSS1335+0728. Methods. We used archival photometry (from WISE, 2MASS, SDSS, GALEX, eROSITA) and spectroscopic data (from SDSS and LAMOST) to study the state of SDSS1335+0728 prior to December 2019, and new observations from Swift, SOAR/Goodman, VLT/X-shooter, and Keck/LRIS taken after its turn-on to characterise its current state. We analysed the variability of SDSS1335+0728 in the X-ray/UV/optical/mid-infrared range, modelled its spectral energy distribution prior to and after December 2019, and studied the evolution of its UV/optical spectra. Results. From our multi-wavelength photometric analysis, we find that: (a) since 2021, the UV flux (from Swift/UVOT observations) is four times brighter than the flux reported by GALEX in 2004; (b) since June 2022, the mid-infrared flux has risen more than two times, and the W1−W2 WISE colour has become redder; and (c) since February 2024, the source has begun showing X-ray emission. From our spectroscopic follow-up, we see that (i) the narrow emission line ratios are now consistent with a more energetic ionising continuum; (ii) broad emission lines are not detected; and (iii) the [OIII] line increased its flux ∼ 3.6 years after the first ZTF alert, which implies a relatively compact narrow-line-emitting region. Conclusions. We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 106M⊙ AGN that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGNobserved in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour. Key words. galaxies: active– accretion, accretion discs– galaxies: individual: SDSS J133519.91+072807.4
Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...Sérgio Sacani
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

Evidence of Jet Activity from the Secondary Black Hole in the OJ 287 Binary S...Sérgio Sacani
Wereport the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ±0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ287 as well as the dense monitoring sample of Krakow.

SCIENCE EXPLAINS THE CAUSES OF THE FINITUDE OF EVERYTHING
Fernando Alcoforado*
This article aims to scientifically demonstrate that living beings and planets like the Earth,
stars like the Sun and the Universe we live in will come to an end due to entropy because
they will evolve over time to a state of disorder. Entropy is commonly associated with the
degree of disorder in a system. The greater the disorder of a thermodynamic system, the
greater its entropy. Entropy is a thermodynamic quantity associated with the
irreversibility of the states of a physical system. The article Sistemas abertos, fechados e
isolados (geologia) (Open, closed and isolated systems (geology)) informs that, in Nature,
three types of systems can be considered [1]: 1) open system, where there is exchange of
energy and matter with the surrounding environment; 2) closed system, where there is an
exchange of energy with the environment, but no exchange of matter, so that it remains
constant and, 3) isolated system, in which there is no exchange of energy or matter.
Living beings are examples of an open system because they are capable of exchanging
energy and matter with the external environment (planet Earth). The planet Earth and the
Sun are examples of closed systems, as they exchange energy with the surrounding
environment, but the exchange of matter is not significant. Our Universe is an example
of an isolated system because it does not exchange matter or energy with parallel
universes, if they exist.
1. Entropy and thermodynamic system
At the beginning of studies on thermodynamics, it was discovered that not all the heat
produced in a steam engine was transformed into work. This energy that was lost from
the system to the external environment was called entropy, which is the ratio between the
amount of heat exchanged with the system and the initial absolute temperature of the
system.. Entropy theory aims to measure the energy degradation that occurs in a system
according to the Second Law of Thermodynamics and the fact that in any physical change
not all of the energy that is in the initial system and that constitutes the body is found in
the system and constitution of the final body. According to the Second Law of
Thermodynamics or second principle of Thermodynamics, the amount of entropy of any
thermodynamic system tends to increase with time, until it reaches a maximum value.
The Second Law of Thermodynamics is related to the concept of entropy. It completes
the First Law of Thermodynamics, which is based on the principle of conservation of
energy. A thermodynamic system consists of input, processing and output elements. The
steam engine is an example of a thermodynamic system that transforms the thermal
energy of steam into mechanical energy using a piston that moves inside a cylinder. The
difference between the heat input to the thermodynamic system of a steam engine and the
output heat corresponds to the work done. A boiler is another example of a
thermodynamic system that produces work by converting the energy of the fuel used into
heat, and therefore into thermal energy. Another example of entropy is the lighting
provided by incandescent lamps, in which not all of the electricity (energy) used is
converted into the form of light (useful energy), but a part is lost as heat (useless energy
for lighting). Thermal energy cannot be completely converted into work due to entropy.
In his work, Até o fim do tempo (Until the end of time) [2], Brian Greene, American
theoretical physicist and mathematician, professor of Physics at Cornell University from
1990 to 1995 and at Columbia University since 1996 and president of the World Science
Festival since 2008, states that, in the case of the steam engine, approximately 95% of the
heat generated by burning wood or coal was lost to the environment as waste. Greene
2. 2
adds that “the Second Law of Thermodynamics applies to the entire Universe. According
to Brian Greene, the Second Law of Thermodynamics describes a fundamental
characteristic inherent in all matter and energy, regardless of its structure or form, whether
animate or inanimate. It reveals that everything in the Universe has the overwhelming
tendency to degrade, deteriorate, languish. Greene also claims, referring to Bertrand
Russell (British mathematician, philosopher, logician and intellectual who had a
considerable influence on mathematics, logic, set theory, linguistics, artificial
intelligence, cognitive science, computer science and various areas of analytical
philosophy , especially philosophy of mathematics, philosophy of language,
epistemology and metaphysics) who said that “the future apparently holds continual
deterioration, a relentless conversion of productive energy into useless heat, a constant
exhaustion, as it were, of the batteries that power reality”. The Second Law of
Thermodynamics applies to living beings like humans, to planets like Earth, to stars like
the Sun and to the Universe in which we live.
2. Entropy of living beings
The article Entropia dos seres vivos (Entropy of living beings) [3] informs that living
beings are open thermodynamic systems, that is, they are capable of exchanging energy
with the external environment. The human body can be compared to a thermodynamic
system that draws heat from a source (food) and does work using part of that energy. The
World Health Organization recommends that every human being, to stay healthy, should
ingest about 2000 food calories daily. As entropy designates the generalized tendency of
all systems in the Universe, whether natural or man-made, to deteriorate, the human body
also goes through a process of entropy because it grows old and one day it dies. Figure 1
explains the entropy of living beings.
Figure 1- Entropy of living beings
Source: https://evolucionismo.org/rodrigovras/termodinamica-e-evolucao-o-velho-argumento-da-
segunda-lei/
Entropy shows us that the order we find in nature is the result of the action of fundamental
forces that, when interacting with matter, allow it to organize itself. Since the formation
of our planet, around five billion years ago, life has only managed to develop at the
expense of transforming the energy received by the Sun into a useful form, that is, capable
3. 3
of maintaining organization. For this, we pay a high price: much of this energy is lost,
mainly in the form of heat. Thus, in order for us to exist, we pay the price of increasing
the disorganization of our planet. When the Sun can no longer provide this energy, in
another five billion years, there will be no more life on Earth..
The article A entropia é contrária à existência de seres humanos? (Is entropy contrary to
the existence of human beings?) [4] reports that the Second Law of Thermodynamics may
seem contradictory to the existence of living organisms, because they are extremely
organized. That is why the dilemma arises of knowing whether its existence is contrary
to this principle of Thermodynamics. The answer is no, there is no contradiction. The
explanation is that all living organisms, be they bacteria, plants or animals, draw energy
from their surroundings, for example, obtaining energy through the combustion of
organic matter, to increase and maintain their complex organization. For this reason,
entropy decreases in living beings. However, that degree of order of its components,
which decreases entropy, continues to increase the entropy around it. So, in summary: all
forms of life, plus the waste products of their metabolisms, have a net increase in entropy.
In addition, to sustain life, it is necessary to transfer energy to the living being. If you fail
to do so, the organism soon dies and always tends towards the destruction of the order it
had, that is, towards disorder or an increase in entropy.
The article Vida, morte e termodinâmica (Life, death and thermodynamics) [5] informs
that living beings, according to thermodynamics, are capable of controlling this disorder
caused by entropy due to the fact that they are open systems, have the capacity to
incorporate free energy received from an external source, allowing the living being to
maintain order in its system. All this causes the life cycle to maintain its thermodynamic
balance. Our life constantly depends on the exchange of substances, and it depends a lot
on solar energy, which is indispensable for life, for the continuation of species and for the
conservation of morphological and functional characteristics. Everything that happens in
Nature means an increase in entropy in the part of the world where it happens. Thus, a
living organism continually increases its entropy – or, as one might say, produces positive
entropy – and thus tends to approach the dangerous state of maximum entropy, which is
death. An organism can only keep itself aloof, that is, alive, through a continual process
of extracting negative entropy from the environment. An organism actually feeds on
negative entropy. All living beings that we know obey the same set of laws: the physical
laws, which govern the macro and microscopic world. All activities carried out by living
beings depend on energy, which, according to Physics, is "capacity to perform work".
With regard to entropy in human beings, it is clear that, over time, our organism is no
longer able to win the battle of life. We begin to feel the effects of time and age. Our body
can no longer keep the skin with the same elasticity, hair falls out and our organs no
longer work properly. At a certain point, a fatal failure occurs and we die. As the
maintenance of life is a struggle for organization, when this ceases, the body immediately
begins to deteriorate and quickly loses all the characteristics that took many years to
establish. The information accumulated over the years, recorded in our brain from specific
configurations of neurons, will be lost and cannot be recovered again with the complete
deterioration of our brain.
3. Entropy and the planet Earth
The article O planeta Terra como um sistema que opera como um organismo vivo (Planet
Earth as a system that operates like a living organism) [13] demonstrates that the Earth
behaves in accordance with the Gaia Hypothesis formulated by scientist James Lovelock,
4. 4
which describes the Earth as a system that operates like a living organism. System is an
integrated set of interrelated and interdependent components that seek to achieve a goal.
The planet Earth is a system that is part of a larger system that is the solar system that is
characterized as a group of planets, small celestial bodies, natural satellites, etc., which
are under the gravitational domain of a star like the Sun. In turn, the solar system is part
of a larger system that is the Milky Way Galaxy, which, in turn, is part of a larger system
that is the Universe. The Earth establishes energetic exchanges with the Universe, suffers
the gravitational effect of the Moon, the Sun and the planets of the solar system, receives
energy emanating from the Sun, which is used in several of its biological and geological
processes and loses energy to space under the heat form.
The article A Terra, o cosmos e a entropia (The Earth, the cosmos and entropy) [6]
informs that planet Earth is not an isolated system. The Earth receives electromagnetic
radiation, mostly coming from the Sun, it is continuously bombarded both by elementary
particles (cosmic radiation, neutrinos, etc.) and by meteorites, and even converts
gravitational energy from the Earth-Moon and Earth-Sun systems into energy mechanics
of planetary fluids (tidal), of which a small part is transformed into heat. However, almost
all energy exchanges between Earth and outer space take the form of electromagnetic
radiation. The article cited above informs that our planet acts as an energy converter or a
net entropy producer and this need imposed by the laws of Physics translates precisely
into the immense phenomenological diversity that occurs on the planet and into the most
astonishing of all phenomena: the life. The circulation of planetary fluids is not only a
gigantic energy conversion machine, but also provides the gathering of substances that
make possible the occurrence of a multiplicity of physical-chemical processes. All these
processes must, according to the 2nd Principle of Thermodynamics, increase the global
entropy. This does not mean that in a particular subsystem of the global system (Earth)
entropy cannot decrease while in the global system the overall balance is positive.
The article A Terra, o cosmos e a entropia (The Earth, the cosmos and entropy) [6] also
informs that the concept of entropy is extremely important when we study the growing
disorder that has occurred on planet Earth, due to the increased exploitation of its
resources, deforestation, pollution, among other sources of degradation. The greater this
degradation, the greater the entropy of the planet, which could reach such a high stage
that life on Earth will no longer be possible (Figure 2).

Entropy shows us that the order we find in nature is the result of the action of fundamental
forces that, when interacting with matter, allow it to organize itself. Since the formation
of our planet, around five billion years ago, life has only managed to develop at the
expense of transforming the energy received by the Sun into a useful form, that is, capable
of maintaining organization. For this, we pay a high price: much of this energy is lost,
mainly in the form of heat. Thus, in order for us to exist, we pay the price of increasing
the disorganization of our planet. When the Sun can no longer supply this energy, in
another five billion years, there will be no more life on Earth.
4. Entropy and the Sun
The book A escalada da ciência e tecnologia e sua contribuição à sobrevivência da
humanidade (The Escalation of Science and Technology and Its Contribution to
Humanity's Survival) [8] reports that the Sun and the rest of the solar system formed from
a giant rotating cloud of gas and dust known as the Solar Nebula. As the nebula collapsed
under its gravity, spinning very fast and becoming flattened into a disk, most of the
material was pulled towards the center to form the Sun. Like most other stars, the Sun is
composed primarily of hydrogen, followed by helium. Almost all the rest of the Sun's
matter consists of seven other elements: oxygen, carbon, neon, nitrogen, magnesium,
iron, and silicon. When the Sun reaches the end of its existence in 4 billion years it will
become a red giant. Astronomers' calculations indicate that when the Sun becomes a red
giant, the Sun's diameter at its equator will grow to the point of surpassing the planet
Mars, consuming all the rocky planets: Mercury, Venus, Earth and Mars. That will indeed
be the end of planet Earth. The Sun's death will occur when it is in an advanced phase of
its life. As its fuel is consumed, the temperature increases and the Sun expands. In this
phase, the Sun is called a red giant. After this stage, the gravitational force prevails and
the star begins to shrink. When that happens, the solar system will fall into chaos and the
Sun will lose a tremendous amount of mass. As it grows, the Sun loses mass and dies,
bringing the solar system to an end.
The article O que é a Morte Térmica do Universo? (What is the Thermal Death of the
Universe?) [7] informs that the end of life of smaller stars, such as the Sun, is not
characterized by a dramatic explosion (supernova), but by a slower process of loss of the
outermost layers until leaving to behind a very massive core, absurdly dense, very hot,
and the approximate size of the Earth, known as a White Dwarf. Even with the drastic
reduction in nuclear fusion capacity, the gravitational collapse of White Dwarfs is
prevented by counterbalancing forces caused by electrons (electronic degeneracy
pressure). Laws of Quantum Mechanics prevent the electrons in atoms from being
squeezed together beyond a certain point (impossibility of occupying the same state),
allowing the stability of the remaining mass. In that sense, the atoms inside a White Dwarf
take on a locked crystalline structure that radiates heat for billions-trillions of years.
Eventually, however, these bodies become extremely cold, giving rise to a Black Dwarf.
5. Entropy and the Universe
The article O que é a Morte Térmica do Universo? (What is the Thermal Death of the
Universe?) [7] also informs that thermal death is the phenomenon in which all processes
in the Universe will eventually stop, because of the action of the temporal flux on entropy,
that is, with entropy continuously growing. In other words, given enough time, energy
will be distributed equally throughout the Universe, and there will be no hot or cold
6. 6
sources to do work, because everything will have the same temperature. When the
Universe reaches its state of maximum entropy - state of thermodynamic equilibrium - no
work will be possible to be done and all available energy will be converted into
unavailable energy. Furthermore, since the moment of the Big Bang, the average
temperature of the Universe has steadily decreased by 10-43
seconds. The initial
temperature of the Universe was 1032 K, but now it's around 2.73 K on average. That is,
the Universe is also moving towards absolute zero (0 K), following the maximum entropy
that tends to "infinity". That is why the Thermal Death of the Universe is also known as
the 'Great Cold'.
The article cited above also informs that, moving towards maximum entropy, only stars
will remain, which will still be able to continue releasing a flow of heat for billions of
years, until the fuel for nuclear fusion runs out and they die. If the mass is sufficient, their
"death" will give rise to either a neutron star or a black hole. The neutron stars will cool
down to the temperature of the surrounding environment, leaving only black holes and a
bit of matter. Without energy for the birth of new stars, there will be no more stars,
galaxies or life. Black holes will begin to suck in all remaining visible matter, and starting
10100
years after the Big Bang, black holes themselves will begin to "evaporate", due to
the emission of Hawking radiation that results from quantum effects from black holes that
can emit radiation with a blackbody spectrum. Only darkness will reign in the Universe,
marking its "death". That would be the probable end of our Universe. In this sense, it is
also easy to understand why the existence of a beginning for the Universe is so obvious.
At that beginning, the entropy of the Universe was so low that it becomes something
beyond comprehension. Everything was concentrated in a singularity, until the explosion
in the form of the Big Bang. This very low entropy is what allows everything we see
today. Everything is happening because the Universe evolved from a very low entropy to
a continuous increase in entropy.
6. Conclusions
Based on the above, all living beings, all planets, all stars and the Universe, which
constitute thermodynamic systems, will come to an end when their respective entropies
reach the maximum value. To avoid the end of human beings as a species, which will
occur with an increase in its entropy, it is necessary to make scientific and technological
advances in medicine that provide the conditions for increasing human longevity. The
article Mundo rumo à singularidade humana (World towards human singularity) [9]
informs that the year 2045 will mark the beginning of an era in which medicine will be
able to offer humanity the possibility of living for a time never seen in history. Organs
that are not working can be exchanged for others, better and created especially for us.
Parts of the heart, lungs and even the brain could be replaced. Tiny computer circuits will
be implanted in the human body to control chemical reactions that take place inside cells.
We will be just a few steps away from immortality. This is the prediction of a group of
scientists known for being at the forefront of research that permeates topics such as
computer science, biology and biotechnology. Among them are George Church, a
professor at Harvard University, in the United States, Aubrey de Gray, a gerontologist
and biomedical specialist in anti-aging, and engineer Raymond Kurzweil, from the
Massachusetts Institute of Technology (MIT). They are the leaders of a new philosophy,
called the Singularity.
To avoid the end of human beings as a species, which could occur with the increase in
entropy of the planet Earth, the Sun and the Universe, it is necessary to overcome the
challenges described below [10]: 1) Production of rockets that reach speeds close to that
7. 7
of light to travel by the Universe; 2) Production of technologies capable of protecting
human beings in space travel; 3) Identification of other Earth-like worlds capable of being
habitable by humans; and, 4) Enabling human beings to survive in space and in habitable
places outside Earth. The first great human challenge is the production of rockets capable
of reaching speeds close to the speed of light (300,000 km/s) given the need to promote
intergalactic travel by human beings to the ends of the Universe and even to other
universes parallel. The second great human challenge is the production of technologies
capable of protecting human beings in space travel by dealing with the lack of gravity and
cosmic radiation, which, on Earth, are protected by the magnetic field and the atmosphere.
The third great human challenge is to identify other worlds similar to Earth capable of
being habitable by human beings by sending space probes to carry out research in possible
locations inside and outside the solar system. So far there is no evidence that there is
another place inside or outside the solar system conducive to Earth-like life. The fourth
great human challenge is the ability of human beings to survive in space and in habitable
places outside the Earth with the development of science and technology to overcome the
biological limitations of human beings.
The article Rumo à colonização de outros mundos (Towards the colonization of other
worlds) [11] informs that, currently, there are efforts to colonize the planet Mars.
However, from what is known about Mars, this planet does not present the necessary
conditions for human beings to inhabit it because it does not have a magnetic field or
atmosphere and biosphere similar to those of Earth, as well as an average gravitational
acceleration of about 38% at of the Earth that is harmful to human life. There is no
evidence on Mars that it has a structured global magnetic field similar to Earth's that
protects us from cosmic rays and solar winds. Mars lost its magnetosphere 4 billion years
ago, but has locally induced magnetism spots. Mars does not have a global magnetic field
to guide charged particles entering the atmosphere, but it does have multiple umbrella-
shaped magnetic fields, mostly in the southern hemisphere, that are remnants of a global
magnetic field that decayed billions of years ago. Compared to Earth, Mars' atmosphere
is very thin. Martian soil is slightly alkaline and contains elements such as magnesium,
sodium, potassium and chlorine that are nutrients found on Earth and necessary for plant
growth.
The aforementioned article also informs that the surface temperatures of Mars vary from
−143 °C (in the winter in the polar ice caps) to maximums of +35 °C (in the equatorial
summer). Mars has the biggest dust storms in the Solar System. These can range from a
storm over a small area to massive storms covering the entire planet. They tend to occur
when Mars is closest to the Sun as its global temperature increases. It is also known that
liquid water cannot exist on the surface of Mars due to the low atmospheric pressure,
which is about 100 times weaker than that of Earth. The two Martian ice caps appear to
be made largely of water. The volume of water frozen in the south polar ice sheet, if
melted, would be enough to cover the entire surface of the planet to a depth of 11 meters.
There was the detection of the mineral jarosite (hydrated sulfate of iron and potassium
formed by the oxidation of iron sulfides), which forms only in the presence of acidic
water, demonstrating that water once existed on Mars. The loss of water from Mars to
space results from the transport of water into the upper atmosphere, where it is dissociated
to hydrogen and escapes the planet due to its weak gravity. Mars has Earth-like seasons
due to the similar inclinations of the two planets' rotation axes. The lengths of Martian
seasons are about twice as long as those on Earth, as Mars is farther away from the Sun,
which makes the Martian year about two Earth years long. The attempt to colonize the
planet Mars could mean the beginning of the process of developing space colonies for
8. 8
use by humans outside Earth. The challenges to colonizing Mars need to be overcome to
make this planet a more immediate escape alternative for humanity when needed.
The article A inteligência artificial na conquista humana do espaço, suas outras
aplicações e seus riscos (Artificial intelligence in the human conquest of space, its other
applications and its risks) [12] reports that Mars, like other planets in the Solar System,
is not even remotely similar to Earth, which is why, to make its colonization possible, it
is necessary to “terraform” it, that is, to reproduce on this planet an environment that
offers the minimum premises for the survival of the human species. Terraforming will be
one of the breakthroughs in the new era of space exploration. Terraforming (adaptation
of the atmosphere, temperature, topography and ecology of a planet or a natural satellite
to make it capable of sustaining an ecosystem with Earth beings) is just one of the
advances expected for the new era of space exploration, in addition to the increase in new
materials and the production of complex cutting-edge propulsion rockets.
To avoid the end of humans as a species, which could occur with increasing entropy and
the end of the Universe, it is necessary to research the existence or not of a multiverse or
parallel universes, which is an important question to study because the existence or not
of a multiverse or parallel universes opens up the possibility of humans surviving the end
of our Universe by heading to other parallel universes. Multiverse is a term used to
describe the hypothetical set of possible universes, that is, parallel universes, including
the Universe we live in. Together, these universes comprise all that exists: the totality of
space, time, matter, energy, and the physical laws and constants that describe them. The
concept of the Multiverse has its roots in extrapolations, so far unscientific, of modern
Cosmology and Quantum Physics, and also encompasses several ideas arising from the
Theory of Relativity in order to configure a scenario in which the existence of countless
universes may be possible where, on a global scale, all probabilities and combinations
occur in some of the universes. Simply because there is enough space to couple other
universes in a larger dimensional structure: the so-called Multiverse [8].
The universes would be, in an analogy, similar to bubbles floating in a larger space
capable of sheltering them. Some would even be interconnected with each other by black
holes, which are cosmic objects whose gravitational pull is so intense that nothing that
penetrates their perimeter – not even light – can escape, or wormholes, which are purely
hypothetical shortcuts between two distant points in the cosmos. That is, it is a tunnel, not
a well. A black hole could function as the entrance to a wormhole. The idea that we live
in a 'multiverse' composed of an infinite number of parallel universes has, for many years,
been considered a scientific possibility. The challenge is to find a way to test this theory.
In-depth research needs to be carried out, therefore, to determine the existence or not of
a multiverse or parallel universes where humanity would head with the end of the
Universe in which we live.
