The COBE satellite observed the cosmic microwave background radiation leftover from the Big Bang, supporting the theory. COBE found the radiation's distribution matched a black body curve at 2.736 K, with some areas slightly warmer. These observations probed conditions in the early universe and provided insights about the ultimate structure of matter, showing protons and neutrons can be broken down into quarks.

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.
Big Bang.ppt
The Big Bang Theory postulates that 13.8 billion years ago, the universe began as a tiny, dense, and hot mass that expanded over time to its present state. Evidence for this includes the cosmic microwave background radiation and redshift of galaxies. The theory has largely replaced earlier non-scientific or disproven theories on the origin of the universe. It explains the evolution of the early universe from the initial hot dense state through nucleosynthesis, formation of stars and galaxies, and ongoing expansion driven by dark energy.

The document discusses several topics related to the universe:
- It originated approximately 13.7 billion years ago from a massive explosion known as the Big Bang. Evidence for this includes the discovery of cosmic microwave background radiation.
- Dark matter makes up 21% of the universe but its exact composition is unknown since it does not emit or reflect light.
- Dark energy is an unknown form of energy that is accelerating the expansion of the universe and accounts for 75% of its contents.
- Black holes are regions of space where gravity is so strong that nothing, not even light, can escape.

Earth Science Astronomy - The big bang theory
The Big Bang occurred approximately 13.7 billion years ago from a single point that contained all matter and energy. Within the first 3 minutes, the universe expanded from the size of an atom to larger than a grapefruit as energy froze into matter. Over hundreds of thousands of years, the first atoms formed, mostly hydrogen and helium. Stars and galaxies began to take shape between 200-400 million years. Our solar system formed 4.6 billion years ago. Evidence for the Big Bang includes the expansion of the universe, cosmic background radiation, quasars, radioactive decay rates, and observations of stellar formation and distances.
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.
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.
Presentation History of the Universe_p.ppt
The document provides an overview of the prevailing Big Bang theory of the origin and evolution of the universe. It describes how approximately 13.7 billion years ago, all matter, energy, space, and time were compressed into a singularity which then began rapidly expanding. As it expanded and cooled, the fundamental forces separated and various phases occurred, including the formation of hydrogen, helium, stars, galaxies, and eventually life on Earth. The Big Bang theory is considered the best explanation for observations of the composition and structure of the universe.

Astronomy
This document provides an overview of astronomy and the origins and structure of the universe. It discusses that the universe contains all matter and energy that exists now and ever will exist. It also notes that every spot of light in the sky is another galaxy, with the Andromeda Galaxy being the nearest at around 2.5 million light years away. The document then summarizes the Big Bang theory, which postulates that the universe began in an extremely dense and hot state around 13-15 billion years ago and has been expanding and cooling ever since.
The_Creation_of_the_Elements_Powerpoint.ppt
The document summarizes key evidence that supports the Big Bang theory of the origin and evolution of the universe. It describes how the Big Bang resulted in the rapid expansion and cooling of the early universe from an incredibly dense and hot state approximately 13.7 billion years ago. It explains how elements like hydrogen, helium, and lithium were formed during nucleosynthesis in the first moments after the Big Bang, and how their cosmic abundances match predictions. It also discusses the cosmic microwave background radiation and redshifts of distant galaxies as further evidence for the Big Bang.
Cosmic microwave background
The Cosmic Microwave Background (CMB) radiation is a faint glow of light that fills the universe from all directions. It was created around 380,000 years after the Big Bang, when the universe had cooled enough for electrons and protons to form hydrogen atoms. On May 20, 1964, American astronomers Robert Wilson and Arno Penzias discovered the CMB radiation. The CMB originated as very hot and bright light but has cooled to 2.73 degrees above absolute zero and stretched into microwave wavelengths due to the expansion of the universe over the past 14 billion years. About 1% of the static between analog TV or FM radio channels is residual CMB radiation from the early universe.

The document discusses several topics related to planetary formation and astronomy. It describes the proto-planet hypothesis which proposes that proto-planets formed from solar nebulae and broke into smaller concentrations. It also discusses the giant impact theory of lunar formation, which is currently the most widely accepted explanation that the Moon formed from a collision between Earth and a Mars-sized object. Additionally, it provides overviews of the Big Bang theory, cosmic microwave background radiation, redshift, black holes, and Kepler's laws of planetary motion.

1. The document discusses the Big Bang Theory and the formation of light elements. It defines the Big Bang Theory as the idea that the universe began as a singularity that rapidly expanded, cooling to form the light elements through nucleosynthesis.
2. The document outlines evidence that supports the Big Bang Theory, including redshift measurements showing galaxies moving away from Earth and the discovery of cosmic microwave background radiation.
3. It explains that Big Bang nucleosynthesis produced the light elements hydrogen, helium, lithium, and beryllium by fusing protons and neutrons during the early expansion and cooling of the universe.
Teoría del Big bang
The Big Bang Theory proposes that the universe began as an infinitely dense, hot singularity that expanded rapidly approximately 13.8 billion years ago. Georges Lemaître first proposed this idea in 1927 that the universe originated from an explosion of a "primeval atom." Edwin Hubble later provided evidence that distant galaxies are moving away from Earth, supporting Lemaître's theory. The theory predicts cosmic microwave background radiation, which was discovered in 1964 and provides strong evidence for the Big Bang. NASA missions like COBE and WMAP have further mapped this radiation and supported inflationary Big Bang models. While well-established, the Big Bang Theory may be refined as new observations are made.
Physical Science 1
1. Stellar nucleosynthesis explains how elements heavier than lithium were formed through nuclear reactions in stars and stellar explosions.
2. Big Bang nucleosynthesis formed the light elements hydrogen, helium, and lithium in the first few minutes after the Big Bang through fusion reactions as the universe rapidly expanded and cooled.
3. Further evidence for the Big Bang model includes the cosmic microwave background radiation and relative abundances of light elements observed today which match predictions from Big Bang nucleosynthesis.
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.
History of the universe, the big bang theory and age of the universe
This presentation is about the history of universe, age of the universe and the big bang. Basically, it can be helpful to high school students.
The big bang theory
1) Newton originally proposed a static, infinite universe that had always existed. However, this did not explain why the night sky is dark.
2) The Big Bang theory emerged as the prevailing explanation for the origin and evolution of the universe. It proposes that the universe began in an extremely hot and dense state around 13.8 billion years ago and has been expanding ever since.
3) Evidence for the Big Bang includes Hubble's discovery of the expanding universe, the cosmic microwave background radiation, and the relative abundances of light elements. Inflation theory further explains properties of the early universe.

- The Big Bang theory proposes that approximately 13.8 billion years ago, the entire observable universe was concentrated into a very hot and dense single point, and then rapidly expanded over time.
- As the universe expanded and cooled, particles formed which then clustered together under gravity to create the first stars and galaxies. Structures like stars and galaxies formed as early as 200 million years after the Big Bang.
- Hubble's law, proposed by Georges Lemaître and later confirmed by Edwin Hubble, describes the observation that galaxies are moving away from Earth at speeds proportional to their distance from us, providing evidence that the universe is expanding.

Presentation Evidence for the Big Bang_p.ppt
Three key pieces of evidence support the Big Bang theory of the origin and evolution of the universe:
1. The expansion of the universe, as evidenced by the redshifting of light from distant galaxies and interpreted by Hubble's law.
2. The abundance of hydrogen and helium matches what would be predicted from nucleosynthesis in the early universe.
3. The discovery of cosmic microwave background radiation, which has properties matching predictions from the Big Bang theory.
The universe
The document discusses our evolving understanding of the universe from theories of both large and small scales over centuries. It describes early geocentric and heliocentric models of the solar system from 2000 and 500 years ago. It then outlines major developments in the last 100-400 years including Einstein's theory of relativity, Hubble's discovery of galaxy expansion, and advances in observational astronomy through powerful telescopes. On small scales, it discusses discoveries like the atomic model from 110-100 years ago and developments in particle physics and nuclear fusion models over the last 50-100 years. In the end, it notes many areas still not fully understood including dark matter, dark energy, reconciling quantum theory with general relativity, and possibilities like string theory and

- 1. The Big Bang • Broadly accepted theory for the origin and evolution of our universe. • 12-14 billion years ago, the visible universe was only a few millimeters across. • It expanded from this hot dense state into the vast cosmos we currently inhabit.
- 2. Tests of Big Bang Cosmology • The Big Bang Model is supported by a number of important observations • The expansion of the universe – The observation that galaxies are receding from us • The abundance of the light elements H, He, Li – these elements were fused from protons and neutrons in the first few minutes after the Big Bang. • The cosmic microwave background (CMB) radiation – The early universe was very hot. The CMB radiation is the remnant heat leftover from the Big Bang.
- 3. COBE • COsmic microwave Background Explorer (COBE) satellite • Observed microwave emissions from the edge of the Universe for two years
- 4. Results from COBE • Distribution of intensities consistent with a black body at 2.736 K
- 5. Results from COBE • Immense clouds that are 2.7 x 10-5 K warmer than background
- 6. Probing the Early Universe • The COBE satellite observed the edge of the visible Universe • Prior to this time, photons were not free to travel through space • It is impossible to see beyond this • The conditions that existed in the Universe at this time can be recreated in the laboratory
- 7. The Ultimate Structure of Matter • Experiments at Fermilab and other particle accelerators show that protons and neutrons can be further broken down into “quarks” • A neutron contains: – 2 down, 1 up quark • A proton contains: – 2 up, 1 down quark
