This theory proposes that galaxies are continuously moving farther apart from each other while maintaining a constant spatial density. As older galaxies move away, new galaxies form from new matter that is continuously created to replace the old galaxies. The theory was originally proposed by Harman Boudi and Thomas Gold and later expanded on by Belgian astronomer and priest Abbe Georges Lemaitre, who suggested that the universe began from an extremely dense state that exploded, spreading fragments that formed into galaxies and stars and have continued expanding since.

Thoeries of the Origin of Solar System
The document discusses several theories of the origin of the solar system. The earliest theories proposed that collisions or condensations from a gas cloud led to the formation of the sun and planets. The currently accepted theory is the nebular hypothesis, which suggests that the solar system formed from a rotating cloud of gas and dust, with material condensing and flattening into a disk that broke into planets, moons, and other celestial bodies. The document also outlines several other older theories, such as the planets and moons forming from material ejected from the sun or collisions between celestial bodies.
Formation
Scientists have developed the Big Bang model to explain how the universe originated and evolved over time. According to this model, around 10-20 billion years ago all matter existed in an incredibly hot and dense state and then expanded and cooled, slowly condensing into stars, galaxies, and eventually planets like Earth. Evidence for the Big Bang model includes the increasing distances between galaxies and the discovery of cosmic background radiation from the early universe.

The document discusses the origin and evolution of the universe from the Big Bang to the present day. It describes how the universe began in a hot, dense state and has been expanding and cooling ever since. As it expanded, the first atomic nuclei formed via nuclear fusion. Over time, these atoms gathered together through gravity to form structures like galaxies, stars, and planets. The document also examines different astronomical objects like nebulae, quasars, and black holes that can be observed in the universe.

The document discusses the formation of the solar system and properties of terrestrial planets. It provides information about asteroids, comets, satellites, and the minor planet Shakespeare. It also includes details about the exoplanet Kepler-22b and compares its properties to Earth and asteroids. Key facts about Kepler-22b are that it was discovered in 2009, has a radius 2.4 times Earth, and is the closest resemblance to Earth found so far, though its composition remains unknown.
Theories of the Universe
The document discusses the origins and early development of the universe according to cosmological theories like the Big Bang theory. It states that the universe began as a very hot and dense ball of matter over 13 billion years ago. As the universe expanded and cooled over hundreds of thousands of years, the basic building blocks of atoms like protons, neutrons and other subatomic particles formed from vibrating strings as proposed by string theory. These simple elements eventually combined to form the first atoms in the growing universe.
Glaxies and the universe
Galaxies are large groups of stars, gas and dust bound by gravity. There are three main types of galaxies: spiral, elliptical, and irregular. Spiral galaxies have winding spiral arms, some with central bars. Elliptical galaxies are large and three-dimensional spheres. Irregular galaxies are smaller and less common with various shapes. Our Milky Way galaxy is a spiral galaxy containing one trillion stars, including our Sun. The Universe contains billions of galaxies, each with billions of stars, that is always evolving as new stars are born and old stars die.

The universe consists of all space, time, matter and energy according to the document. It began expanding after the Big Bang, and astronomers believe the expansion will continue indefinitely due to the presence of dark matter and an unknown accelerating force. The universe contains galaxies which are grouped into larger structures called clusters. Galaxies themselves contain stars, nebulae, black holes and other astronomical objects. Stars are born in nebulae and pass through various life stages involving nuclear fusion until ending as white dwarfs or exploding as supernovae.

The universe contains galaxies which are grouped into larger structures called clusters. Galaxies themselves contain stars, nebulae, black holes and other astronomical objects. Stars are born in nebulae and pass through various life stages involving nuclear fusion until ending as white dwarfs or exploding as supernovae.
THE UNIVERSE
The universe is composed of ordinary visible matter (4%), dark matter (21%), and dark energy (75%). Dark matter's existence was postulated to explain gravitational forces, while dark energy causes the accelerated expansion of the universe. The Big Bang theory proposes that approximately 13.7 billion years ago, the universe began as a very dense, hot mass that exploded and expanded. Evidence for this includes the cosmic microwave background radiation and the formation of light elements. Galaxies formed over time and come in elliptical, spiral, and irregular shapes. Stars form from clouds of dust and gas through gravitational collapse and nuclear fusion.
Origin of the universe
The universe is approximately 13.8 billion years old and contains countless galaxies, many with supermassive black holes at their centers. The Milky Way galaxy is the one that contains our solar system. According to the leading Big Bang theory, the universe began as an extremely hot and dense singularity which expanded rapidly approximately 13 billion years ago, resulting in the formation of hydrogen and helium from the cooling nuclear matter. Evidence for the expansion of the universe and the Big Bang model includes the redshift of distant galaxies and the discovery of cosmic microwave background radiation.
Steady state theory
The Steady State Theory proposed that the universe has no beginning or end in time and appears the same from any point. It suggests new stars are continually created to replace those that have died, maintaining a steady state. The theory was proposed as an alternative to the Big Bang Theory. However, evidence emerged in the 1960s that contradicted Steady State Theory, including more distant radio sources in the early universe, discovery of quasars only in the early universe, and detection of the cosmic microwave background radiation, which is difficult to explain under Steady State Theory. The theory has since been discarded.
Universe and Galaxy ppt
The document discusses the universe, galaxies, and the solar system. It begins by explaining that the universe contains everything that exists, but its size and boundaries are unknown. Galaxies are gravitationally bound systems of stars, gas and dust, such as the Milky Way galaxy. The solar system is located in the Milky Way and contains the Sun and objects that orbit it directly or indirectly, including planets, dwarf planets, asteroids and comets. Black holes are regions of spacetime where gravity is so strong that nothing can escape. The document then provides brief descriptions of asteroids, comets, meteorites and other astronomical objects that make up the observable universe.
grade 11 Chapter 1 Origin of the Universe
The document discusses theories about the origin of the universe. It begins by explaining the widely accepted Big Bang theory - that approximately 13.7 billion years ago, all the energy and matter in the universe was compressed into a hot, dense state, and then exploded, expanding and cooling to form the current universe. It then briefly describes some alternative theories, including the creationist theory of a divine creator, the oscillating universe theory of repeated expansion and collapse cycles, and the steady state theory that the universe has always been the same. The document provides examples of galaxies and defines key terms like universe and cosmos.
Chapter 1 origin of the universe
This document provides an overview of theories on the origin of the universe and the solar system. It begins by defining important terms like dark matter, dark energy, and theories. It then discusses creation myths from different cultures and the biblical creation story in Genesis. The majority of the document focuses on explaining the Big Bang Theory, including the inflation epoch, events after the Big Bang like formation of the basic elements, and evidence that supports it like galaxy redshifts and the cosmic microwave background. It also briefly outlines other theories like the steady state theory, string theory, and M-theory. The second half summarizes theories of solar system formation like the nebula hypothesis and compares terrestrial and Jovian planets.
The Galaxy by Myrell Esteban (I Made)
The document discusses two models of galaxy formation:
1) The classical or monolithic model which proposes that galaxies form in isolation with little environmental impact.
2) The hybrid hierarchical model which proposes that galaxies form through successive mergers of smaller bodies and their evolution depends more on their environment. The document provides evidence that supports the hierarchical model including cold dark matter, observations of small blue galaxies, star formation rates, cluster shapes, and observations of the Hubble Deep Field. It also discusses properties of active galaxies, quasars, and differences between normal and active galaxies.
Life cycle of a star
This document discusses the life cycle of stars from their formation to their death. It begins by explaining that stars are giant balls of exploding gas made up mainly of hydrogen and helium. The document then outlines the various stages of a star's life: nebula, protostar, main sequence star, red giant, white dwarf, supernova, neutron star, and black hole. For each stage, it provides a brief description of the physical changes occurring within the star. The document emphasizes that stars much more massive than our sun will end their lives as neutron stars or black holes through the supernova process.
Life Cycle Of Stars
All stars begin as nebulae of dust and gas that collapse under gravity into protostars. They fuse hydrogen into helium during the main sequence stage, which is the longest phase in a star's life. A star's ultimate fate depends on its mass. Small mass stars become white dwarfs after the main sequence, while medium mass stars become red giants then white dwarfs. Large mass stars over 15 solar masses may explode as supernovae, leaving behind neutron stars or black holes.
Steady State Theory
The document provides information about the Steady State Theory and compares it to the Big Bang Theory. It discusses that the Steady State Theory proposes that the universe has always existed and is essentially the same at any point in time, with new matter constantly being created. In contrast, the Big Bang Theory suggests the universe began from an initial hot, dense state and has been expanding ever since. The document outlines similarities and differences between the two theories, such as their explanations for the cosmic microwave background. It also discusses evidence that emerged in the 1960s that contradicted the Steady State Theory, like observations of more radio sources in the early universe and the discovery of quasars.
Big Bang
The document discusses evidence that supports the Big Bang theory of the origin and expansion of the universe. It explains that background radiation from the early universe, the observation of galaxies moving away from Earth, and a temperature of about 3 degrees above absolute zero provide observational evidence for the Big Bang. It also outlines two possible futures for the universe - either continuing to expand indefinitely or eventually collapsing back on itself and undergoing another Big Bang.
Evolution of universe - Geochemistry & Thermodynamics
The document summarizes the evolution of the universe. It discusses the origin and formation of the universe according to the Big Bang theory. The universe began as a very hot and dense state around 13.8 billion years ago, which then expanded and cooled to form stars, galaxies, and other celestial objects. The document also describes the components that make up the universe such as galaxies, stars, and black holes. It discusses the chemical composition and forces that govern the motion of objects in the universe.
Expanding universe
This document describes the evolution of cosmological models throughout history from ancient Earth-centered models to the current Big Bang model. It discusses how each new model was developed in response to new observations that could not be explained by existing models, from Copernicus developing the Sun-centered model to resolve issues with planetary retrograde motion to Hubble establishing the expanding universe model based on the observation of redshift in galaxies. The document also outlines how new discoveries like dark matter and dark energy have led to refinements of the Big Bang model but not a rejection of the overall framework. It emphasizes that science advances through an ongoing process of testing predictions made by models against observations.
Origins of the Universe
This will talk about the origins of the universe and how it came to be. It is a summary of how different theories made the universe.
The secrets of universe
This document summarizes theories about the formation and evolution of the universe and galaxies. It discusses that according to the Big Bang Theory, the universe was created 13.8 billion years ago and has been expanding ever since. Galaxies formed as matter clustered together due to gravitational attraction. Stars formed within galaxies by nuclear fusion, producing heavier elements. When large stars died in supernovae, even heavier elements were created. These elements could provide the raw materials from which planets, and eventually life, developed. The future of humanity within this immense and evolving cosmic landscape remains uncertain.

07 Universe Mc Neely
The document discusses evidence that supports the Big Bang theory of the origin and evolution of the universe over 13.7 billion years. It describes how the universe began in a hot, dense state and has been expanding ever since, as evidenced by the redshift of distant galaxies and the cosmic microwave background radiation. The Big Bang theory postulates that all matter was originally concentrated in a single point that exploded, resulting in the current expanding universe.
Universe and the bigbang
The document discusses the universe and the Big Bang theory. It provides information on:
1) The universe consists of space, time, matter, and energy. Some hypotheses suggest there may be more dimensions and other universes beyond what we can observe.
2) Hubble's law established that galaxies are moving away from Earth and the farther away they are, the faster they recede. This supported the idea that the universe began as a single point and has been expanding ever since.
3) The Big Bang theory proposes the universe expanded from an initial extremely dense and hot state approximately 13.8 billion years ago. It explains phenomena like the cosmic microwave background radiation and abundance of light elements.
Formation of the universe
It focusses on the three theories in the formation of the universe namely; Big Bang Theory, Steady State Theory and the Cosmic Inflation Theory.
Chapter 19 – formation of the universe
The document summarizes theories about the formation and evolution of the universe:
1) The Big Bang theory proposes that approximately 13.8 billion years ago, all matter in the observable universe was condensed into an incredibly dense singularity that suddenly exploded, causing the universe to expand rapidly and form light elements.
2) As the universe expanded, gravity caused matter to condense into the first stars and galaxies. Observations of redshifts in light from distant galaxies provide evidence the universe continues expanding today.
3) Current theories suggest three possible ultimate fates for the universe depending on its overall density - continued expansion, eventual contraction, or a stable flat state.
Module 1 origin and systems of earth
1. James Hutton established the theory of uniformitarianism, which states that the geological forces shaping Earth today are the same as in the past. He is considered the founder of modern geology.
2. Charles Darwin developed the theory of evolution through natural selection, which explained how species change over time in response to their environment.
3. Andrija Mohorovicic discovered the boundary between Earth's crust and mantle, known as the Mohorovicic discontinuity or "Moho".
4. Beno Gutenberg studied earthquakes and discovered that their waves can be used to investigate Earth's internal structure
Evolution of universe
The document discusses the evolution of the universe from the Big Bang theory to present day. It covers:
1) The Big Bang theory which proposes the universe began as a hot, dense point around 14 billion years ago and has been expanding and cooling ever since.
2) The formation of stars, galaxies, and planets as the universe evolved, with our solar system forming around 5 billion years ago.
3) Two other theories - the Steady State theory which proposes the universe has always existed in a constant state, and the Pulsating universe theory.

The document discusses the origin and evolution of the Earth and the universe according to the Big Bang theory. It provides evidence from astronomers like George Lemaitre, who first proposed the Big Bang theory, and Edwin Hubble, who provided evidence of an expanding universe. The Big Bang theory states that approximately 13.7 billion years ago, the entire observable universe was concentrated into a very dense and hot singularity, and then rapidly expanded resulting in the formation of all matter. Astronomers have detected cosmic microwave background radiation and redshifts in distant galaxies as confirmation of the Big Bang.

Big_Bang_Presentation_Slides.pptx
The document summarizes the major events from the Big Bang theory, including the formation of the universe approximately 15 billion years ago, the formation of the Milky Way galaxy and the Earth, and the emergence of early life on Earth. It describes how hydrogen and helium formed after the Big Bang and later condensed into galaxies and stars. The formation of heavier elements in supernovae explosions is noted. Key events in the development of life on Earth such as the appearance of prokaryotes, eukaryotes, and multicellular organisms are highlighted.
Origin of the Universe
1. The Big Bang Theory proposes that the universe began approximately 13 billion years ago with the rapid expansion of matter and energy from a hot, dense state.
2. Edwin Hubble discovered that galaxies exist outside the Milky Way and are moving away from each other, providing evidence that the universe is expanding.
3. Evidence for the Big Bang includes the cosmic microwave background radiation, which is remnants of light from the early universe, and relative abundances of light elements like hydrogen and helium.

notes in physical science week 1 quarter three
This document summarizes how scientists believe the elements and structures in the universe formed beginning with the Big Bang. It describes an experiment using a balloon with dots to model the expansion of the early universe, showing that farther dots moved faster as the balloon inflated, similar to how galaxies farther from Earth are moving away more quickly. The document then explains how following the Big Bang, simple elements like hydrogen and helium formed as the universe cooled, which then fused into heavier elements as the first stars formed, leading eventually to the formation of planets, life and humans. It also briefly discusses evidence supporting the Big Bang theory and some open questions about the shape and ultimate fate of the universe.
Black Holes Research Paper
Black holes are regions of space with immense gravitational pulls that do not allow nearby objects to escape. They form when very massive stars collapse at the end of their life cycles. A star must be at least 3 times the mass of our sun to collapse into a black hole upon supernova. There are several stages a massive star goes through over millions of years, fusing lighter elements until an iron core forms and collapses, which may then become a black hole. Scientists have developed theories about black holes over time, but many questions still remain about their exact nature and effects.
THE BIG BANG THEORY, ITS MISCONCEPTIONS AND EVIDENCES
This document discusses astronomy, physics, chemistry, and the Big Bang Theory. It provides definitions and explanations of astronomy as the study of objects and matter outside Earth's atmosphere. Physics is defined as the study of physical forces, qualities, matter, energy, and their interactions. Chemistry deals with the composition, structure, and properties of substances. The document then explains the current Big Bang Theory, which proposes that the universe rapidly expanded from an infinitely dense, hot singularity approximately 13.8 billion years ago. It formed light elements during this rapid expansion and continued to evolve, forming stars and galaxies. Evidence for the theory includes the expansion of the universe and detection of cosmic microwave background radiation. [/SUMMARY]
Galaxies revo1
This document provides information about galaxies and theories of the origin of the universe. It begins with introductions from Celestial and Cosmos who are interested in astronomy and space travel. It then defines a galaxy as a large collection of stars, gas and dust held together by gravity. It provides examples of spiral galaxies like the Milky Way and Andromeda, and notes that Andromeda is approaching the Milky Way. The document also describes elliptical, lenticular, irregular and peculiar galaxies. Finally, it summarizes the Big Bang theory that the universe began as a single point and has been expanding ever since, and the steady state theory that the universe is always expanding but maintaining a constant density through continuous creation of new stars.
2 BIG BANG THEORY AND PIECES OF EVIDENCE
The document discusses the structure, composition, and origin of the universe according to the Big Bang theory. It begins by explaining that the universe is approximately 13.7 billion years old and composed of various forms of matter and energy. It then discusses early hypotheses for the origin of the universe before introducing the Big Bang theory. The Big Bang theory proposes that the universe began from an extremely hot, dense singularity which expanded and cooled over billions of years, allowing the formation of hydrogen, helium, and later heavier elements. Key evidence for the Big Bang theory includes the observation of galaxy redshifts, the discovery of cosmic microwave background radiation, and the abundance of light elements.

The document provides an overview of the evolution of the universe from the Big Bang to present day. It describes how:
1) The Big Bang theory postulates that the universe rapidly expanded from an extremely dense and hot state around 13.8 billion years ago.
2) Galaxies, stars, and planets formed as the universe cooled and expanded.
3) The universe continues to expand today, as first observed by Edwin Hubble.
4) Key events in the evolution of the Earth and life are also summarized, such as the formation of the Moon, emergence of oxygen in the atmosphere, periods of glaciation, mass extinctions, and movement of tectonic plates.

The univese
- 20. This theory was given by Harman Boudi and Thomas Gold. According to this theory “Galaxies are continuous moving faraway from each other. But their spatial density remain constant. Because of that old galaxies move apart and new galaxies take their position. And these new galaxies are formed by new matter which is being continuously created to replace of old galaxy.
- 21. This theory was given by Belgian Astronomer and Priest “Abbe Georges Lemaitre”. 1. He Said that billion of year ago, Universe or Cosmic matter was in an extremely compressed state. 2. There expansion was started after big explosion. 3. This explosion broke up Super dense ball and Spread their fragments far out into space, where they are still traveling with the speed of thousand of miles per second. 4. And these moving fragments metal (dust and gases) have formed galaxies. 5. The formation of galaxies and starts has not stopped or hold the speed of expansion and farthest pieces are flying the fastest.
