The document discusses the Big Bang theory, which states that the universe began in an enormous explosion roughly 13.8 billion years ago from a single point that contained all mass and space. It explains that the universe has been constantly expanding ever since. The Big Bang theory was discovered through the work of scientists like Alexander Friedman, Georges Lemaître, and Edwin Hubble in the 1920s and 1930s, who provided evidence of an expanding universe through observations of galaxies moving away from Earth and remnants of the early universe.

Big Bang Theory
The document discusses the Big Bang theory, which proposes that the universe began approximately 13.8 billion years ago from an extremely dense and hot state and has been expanding and cooling ever since. It provides an overview of the theory's history, key scientists like Friedman, Lemaître and Hubble who contributed to its development, and major evidence that supports it, including cosmic microwave background radiation, the abundance of light elements, and the observable expansion of the universe. The document also notes there were four fundamental forces in the early universe and that the theory was named by Fred Hoyle in 1950.
Courtney Big Bang Theory
The document summarizes the Big Bang theory, which proposes that approximately 13.7 billion years ago, the entire observable universe was concentrated into a very hot and dense single point that suddenly expanded. As it expanded, the universe cooled and matter formed, eventually coalescing through gravity to create stars, galaxies, and other celestial bodies. Scientists know this occurred because the universe is still expanding today and the abundance of elements like helium match predictions of nuclear fusion in the hot early universe. The discovery of redshift also supported the expansion of the universe since the wavelength of light from distant galaxies stretches as space expands. Astronomer Edwin Hubble helped establish the Big Bang theory through his discovery that galaxies are moving away from Earth at speeds proportional to their distance
Big Bang 1
The document discusses the Big Bang theory, which proposes that the observable universe expanded from an initial extremely hot and dense singularity around 13.8 billion years ago. It describes how the Big Bang originated from a tiny, dense point that exploded, causing galaxies to expand outward. Observational evidence that supports the Big Bang theory includes the discovery of cosmic microwave background radiation and primordial elements like helium and deuterium in ancient stars and distant reaches of the universe. The document also notes that the Big Bang theory is constantly revised as new evidence and theories emerge.

The big bang theory
The Big Bang theory proposes that the universe began from an initial expansion approximately 13.8 billion years ago from a very dense and hot state. Albert Einstein's theory of relativity and Edward Hubble's discovery that galaxies are moving away from each other provided evidence supporting this idea. While there was no explosion, there was an expansion from something very small that rapidly expanded the universe without borders, and it continues expanding today with many unanswered questions about what triggered the initial expansion.
Cosmologies
Two modern cosmologies are outlined: the Big Bang Theory and the Expanding Universe Theory. The Big Bang Theory proposes that approximately 18 billion years ago, the universe exploded into existence from a single point. This is supported by the Second Law of Thermodynamics, which states that the universe is constantly increasing in disorder, and by gravity, as described by Newton. The Expanding Universe Theory, developed in the 1920s by Edwin Hubble, found that galaxies are moving away from each other, indicating the universe is expanding from an initial smaller state, supporting the idea of an initial explosion that set the universe in motion.

origin of universe & big bang theory
The document summarizes the 10 key steps in the generally accepted theory of the formation and evolution of the universe according to the Big Bang theory:
1) The universe began as an incredibly hot, dense point that rapidly expanded in an event known as the Big Bang.
2) The universe underwent a period of rapid exponential expansion known as inflation shortly after the Big Bang.
3) Light chemical elements like hydrogen and helium formed in the first few minutes as the universe cooled and expanded.
4) After about 380,000 years, the universe cooled enough for light to shine through for the first time.
5) The first stars and galaxies emerged from the "cosmic dark ages" over the
Big Bang Daniels
The document summarizes the origin and evolution of the universe from the Big Bang to the present day. It describes how the Big Bang created a hot, dense soup of particles that cooled over time and coalesced under gravity to form the first stars and galaxies. It explains that our solar system and planet Earth formed from a cloud of dust and gas within the Milky Way galaxy. The universe continues expanding today as a result of the initial Big Bang and its ultimate fate remains uncertain.
Universe Theories
The document discusses multiple theories about the origins and age of the Earth and universe:
1) Young Earth Creationism believes the Earth was created by God around 10,000 years ago based on a literal interpretation of the Bible.
2) The Big Bang Theory proposes the universe rapidly expanded from an initial extremely hot and dense state around 13.8 billion years ago.
3) The author finds the Creationist Theory most convincing as it posits the universe was created by God, rather than arising from nothing as the Big Bang Theory suggests.
The universe
The document discusses the origin of the universe according to the Big Bang theory. It states that around 15 billion years ago, a huge mass exploded, sending pieces expanding in all directions to form galaxies, and the galaxies have continued separating and the universe expanding ever since. The theory developed from discoveries made in 1923 when Edwin Hubble created the largest telescope in the world and observed that the universe is expanding.

BIG BANG
The document discusses theories about the origin and evolution of the universe. It begins by introducing the Big Bang theory, which most widely held view that approximately 14 billion years ago, the universe rapidly expanded from a high-density and high-temperature state. It then discusses other historical and religious beliefs about the universe, as well as alternative theories such as the Big Crunch theory, which hypothesizes the universe will eventually stop expanding and collapse back in on itself.
Creation of universe
The document discusses the creation of the universe from both scientific and Islamic perspectives. It describes the scientific Big Bang theory, which holds that the universe began in an enormous explosion from a single point of extremely dense matter around 13.8 billion years ago. It notes parallels between modern scientific understandings of the beginning of the universe and descriptions in the Quran from over 1400 years ago, including creation from nothingness, a tiny initial volume, and expansion of the universe. The document concludes by emphasizing from an Islamic viewpoint that Allah is the creator of the entire universe and everything within it.
Evolution of universe
The document discusses several scientific theories related to the origin and evolution of the universe:
1) Relativity Theory proposed by Einstein in 1916 that proved the universe was continuously expanding from a beginning point, known as the Big Bang.
2) The Big Bang Theory, first proposed by Lemaitre in 1927, that the universe began in an extremely hot and dense state around 13.8 billion years ago.
3) The Steady State Theory, an alternative to the Big Bang proposed in 1948, that the universe has always existed and matter is continuously created as it expands.
4) In 1965, scientists discovered Cosmic Microwave Radiation, evidence Lemaitre had predicted in support of the Big
Alternative Theories Of The Univers
The document discusses several alternative theories of the origins and evolution of the universe:
1) The Big Bang Theory proposes that the universe began from an infinitely dense, hot state and has been expanding ever since.
2) Creationist theories suggest that the universe was created by God or a divine being, with varying views on the age of the Earth and role of evolution.
3) The Stoic Universe theory proposes a finite universe surrounded by an infinite void that undergoes periodic upheavals and events.
4) The Oscillation theory proposes a perpetual cycle of expansion from a Big Bang and subsequent contraction into a Big Crunch.
Theories Of The Universe
The document discusses two theories of the formation of the universe:
1) The Big Bang theory, which proposes that the universe was created 13.7 billion years ago by an enormous explosion that caused the contents of the universe to be compressed under extreme pressure and density. As time passed, the universe continued expanding and cooling.
2) An alternative theory that proposes the universe was formed from the collapse of a gaseous nebula. As the nebula collapsed under pressure, it flattened and fragments broke off to form the sun and other masses, which eventually became the universe through gravitational pull.
The origins of the universe
The document provides a summary of modern scientific theories about the origins of the universe from the Big Bang to the formation of stars and galaxies. It discusses how after the Big Bang around 13 billion years ago, the universe rapidly expanded from an incredibly small and hot size. Around 300,000 years later, the first atoms like hydrogen and helium formed as the universe continued expanding and cooling. Gravity eventually pulled matter together, forming dense clouds that collapsed under their own weight and spawned the first stars and galaxies. Our own solar system formed around 4.6 billion years ago from the debris of the Sun.
Theories of the Universe
The document discusses several cosmological theories including the Big Bang theory, inflation theory, and 2012 theory. It provides a brief overview of each theory, noting that the Big Bang theory proposes the universe rapidly expanded from an initial extremely dense and hot state around 13.7 billion years ago, while inflation theory was developed to address perceived issues with the Big Bang theory. The document expresses skepticism about the 2012 theory claiming the world will end in 2012.
Big Bang theory
The document summarizes the Big Bang theory, which proposes that the universe began as a singularity around 13.8 billion years ago and has been expanding ever since. It describes the early development and timeline of the universe from the initial singularity through inflation, baryogenesis, and cooling. The theory is supported by evidence like the cosmic microwave background radiation and Hubble's law of universal expansion. The future of the universe is uncertain but may involve continued expansion, eventual contraction, or a flat, stable state.
Introduction to Astronomy Notes
The scientific study of the universe has evolved over time as new evidence and theories have emerged. Originally, it was thought that Earth was at the center of the universe with objects orbiting in perfect circles (the geocentric model). However, careful observations found inaccuracies, leading to proposals of sun-centered models by Copernicus and Kepler. Kepler determined planets orbit in ellipses with the sun at one focus. Galileo's telescope provided further evidence supporting a heliocentric model. Today astronomers use various telescopes to study and better understand the universe.
Theories of the end of the world
This short document discusses several topics including comparing scientific theories, preparing for a super volcano eruption, whether North Korea has nuclear weapons, and creating diseases for profit. The document asks for opinions on which scientific theory is more believable, what actions would be taken if a super volcano erupted, whether North Korea possesses nuclear arms, and thoughts on developing diseases for financial gain.

1. Apple's strategy of tightly integrating hardware, software and services has allowed it to create innovative products with great user experiences. However, its hyper-focus on design and secrecy could be a weakness if competitors are able to copy aspects of its strategy.
2. If I were responsible for Apple, I would focus on maintaining innovation leadership while also improving supply chain transparency and working conditions. Building better relationships with regulators and communities around its factories would help address criticisms. I would also explore new product categories and business models to sustain long-term growth.

The document provides information about the Big Bang theory, which suggests that the universe began approximately 13.8 billion years ago from a dense singularity and has been expanding ever since. It discusses key aspects of the theory including nucleosynthesis, the cosmic microwave background radiation, and evidence that supports the theory. The major proponents who contributed to the development of the theory are identified as Georges Lemaitre, Edwin Hubble, Arno Penzias, and Robert Wilson. The document also notes that the Big Bang theory fails to fully explain how the universe was originally created.
Big Bang Theory Earth SUn moon year.pptx
The Big Bang Theory proposes that the universe began as an extremely dense singularity which expanded over time, causing a decrease in density as the volume increased. Originally with an infinitely small volume and extremely high density, the universe has expanded exponentially over billions of years, decreasing its density as its volume increased. This explains how the universe has changed from its initial state of high concentration of mass within a small space to a lower density as that same mass is spread over a vastly greater volume today.
Big bang theory explained
The document discusses the Big Bang theory, which proposes that the universe began approximately 13.8 billion years ago from an extremely hot and dense initial state. It then rapidly expanded. As it cooled, simple atomic elements like hydrogen and helium formed. Over billions of years, giant clouds of these elements coalesced through gravity to form stars and galaxies. The theory is supported by observations of galaxy expansion, cosmic microwave background radiation, and abundances of light elements in the universe. The Big Bang was not an explosion in space, but rather an ongoing expansion of space itself that continues today.

The document discusses the evolution of the universe from the Big Bang theory. It describes the Big Bang theory as the most accepted explanation for the origin and early development of the universe. It states that before the Big Bang, there was nothing - no time, no matter. After the Big Bang, the universe began rapidly expanding from an extremely dense and hot state. As it expanded, the early universe progressed through different eras from radiation to the formation of atoms, galaxies, and stars. The expansion of the universe continues today.

Georges Lemaître proposed the Big Bang theory in the 1920s to explain observations that galaxies were moving away from each other and the universe was expanding. His theory was initially rejected but gained acceptance in the 1950s as evidence accumulated. The Big Bang theory proposes the universe began in a hot, dense state and has been expanding and cooling ever since. Lemaître's theory is now central to modern cosmology and he is considered the father of the Big Bang theory, though his religious beliefs led him to advise against linking the theory directly to divine creation.

The document summarizes theories about the formation and evolution of the universe. It describes the biblical creation story, then focuses on the prevailing scientific theories of the Big Bang and steady state. It explains that according to the Big Bang Theory, the universe rapidly expanded from an incredibly hot, dense singularity around 14 billion years ago. Key figures who advanced the theory, like Lemaitre, Hubble, Gamow and Penzias and Wilson, are also mentioned. Alternative theories like the steady state and oscillating universe models are briefly outlined.
Earth-Science-SHS-1.1-Big-Bang-Theory.pdf
The big bang theory explains how the universe began approximately 13.8 billion years ago from a dense, hot singularity. The universe expanded rapidly from this initial state in a process known as inflation. As it expanded, light elements like hydrogen and helium formed. Evidence for the big bang includes the expansion of the universe observed through Hubble's law, the cosmic microwave background radiation leftover from the early universe, and abundances of light elements. Georges Lemaître first proposed the theory in the 1920s, with Edwin Hubble and later Arno Penzias and Robert Wilson providing crucial observational evidence through their discoveries.
Cosmologies
Two modern cosmologies are outlined: the Big Bang Theory and the Expanding Universe Theory. The Big Bang Theory proposes that approximately 18 billion years ago, the universe exploded into existence due to the Second Law of Thermodynamics and the force of gravity. The Expanding Universe Theory, developed in the 1920s, holds that galaxies are moving apart, indicating the universe was once smaller and has been expanding since an initial explosion set it in motion.
Big Bang Theory
The Big Bang theory proposes that the universe began as an extremely hot and dense singularity around 13.75 billion years ago and has been expanding ever since. It is supported by evidence such as Hubble's Law that galaxies are moving away from us and the discovery of cosmic microwave background radiation, which is leftover radiation from the early universe. Some criticisms of the theory are that it does not fully explain the formation of structures like galaxies. The theory also depends on assumptions about the universality of physical laws and the cosmological principle.

Thebigbangtheory
The document summarizes the Big Bang theory, which proposes that the universe began approximately 13.7 billion years ago from a very hot and dense initial state known as a singularity. It describes how scientists like Einstein, Friedmann, Hubble, Penzias and Wilson contributed evidence through discoveries like cosmic microwave background radiation and redshift that supported the expansion of the universe from this initial point. The document also addresses some common misconceptions about the Big Bang, such as that it was not an explosion but rather an expansion, and that the singularity did not appear in space but rather space began inside the singularity.

BIG BANG THEORY how the earth started.pdf
The document provides an overview of the Big Bang theory, which describes how the universe expanded from an extremely dense and hot state shortly after the inferred Big Bang around 13.8 billion years ago. It explains that early in the expansion, the universe was a singularity containing all matter, energy, space, and time. As it rapidly expanded and cooled, the fundamental forces separated and simple elements like hydrogen and helium formed. Observational evidence like the cosmic microwave background radiation supports the Big Bang theory as the prevailing explanation of the universe's origins and development.

Carrer goals.pptx and their importance in real life
Career goals serve as a roadmap for individuals, guiding them toward achieving long-term professional aspirations and personal fulfillment. Establishing clear career goals enables professionals to focus their efforts on developing specific skills, gaining relevant experience, and making strategic decisions that align with their desired career trajectory. By setting both short-term and long-term objectives, individuals can systematically track their progress, make necessary adjustments, and stay motivated. Short-term goals often include acquiring new qualifications, mastering particular competencies, or securing a specific role, while long-term goals might encompass reaching executive positions, becoming industry experts, or launching entrepreneurial ventures.
Moreover, having well-defined career goals fosters a sense of purpose and direction, enhancing job satisfaction and overall productivity. It encourages continuous learning and adaptation, as professionals remain attuned to industry trends and evolving job market demands. Career goals also facilitate better time management and resource allocation, as individuals prioritize tasks and opportunities that advance their professional growth. In addition, articulating career goals can aid in networking and mentorship, as it allows individuals to communicate their aspirations clearly to potential mentors, colleagues, and employers, thereby opening doors to valuable guidance and support. Ultimately, career goals are integral to personal and professional development, driving individuals toward sustained success and fulfillment in their chosen fields.

Big bang
- 1. The Big Bang By: Lorenzo Díez-Picazo and Junho Lee
- 2. What is the Big Bang? • Model that explains the origin of the Universe.
- 3. What does this theory state? • The universe started with a big explosion. • The universe is in constant expansion. • At first all of space was concentrated in a single point. • Massive electrically neutral atoms formed stars and galaxies.
- 5. Who discovered the big bang? • There is not only one scientist who has discovered this theory but many little discoveries and arguments that make us believe that this theory is true
- 6. • The works of Alenxader Friedman and Georges Lemaître during the 20´s using the theory of relativty. • Edwin Hubble discovered in 1929 galaxies (farer away from the milky way) that were getting away from the Earth. • Space engineers have said that they have heard the waves of the expansion. • Scientist say that at the begining of the universe, temperatures were hotter and they are getting cooler (in space).
