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.

The document summarizes the Big Bang theory in three main points:
1. The universe began approximately 13.7 billion years ago from a single point of pure energy in an instant, expanding from the size of an atom to larger than a grapefruit within the first 3 months. The early universe was mostly hydrogen and helium.
2. The first stars and galaxies formed between 200-400 million years after the Big Bang. Our solar system formed around 4.6 billion years ago.
3. Misconceptions about the Big Bang include that it was not an explosion but rather an expansion like a balloon growing to the size of the current universe.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 hot dense state. Albert Einstein's theory of relativity and Edwin Hubble's discovery that galaxies are moving away from each other provided evidence for this theory. According to the Big Bang, the early universe underwent rapid inflation and cooling, allowing the formation of protons, neutrons, and eventually atoms of hydrogen and helium as it expanded and evolved into the present cosmos.The big bang theory

This document discusses scientific theories and the Big Bang Theory. It provides definitions of key terms like scientific theory, fact, and law. It explains that a scientific theory is well-supported by evidence but is not absolute fact. The document then summarizes the development of the Big Bang Theory, including contributions from Einstein, Friedman, and Hubble. It describes how evidence from the cosmic microwave background and galaxy redshifts supports the idea that the universe expanded from a hot, dense initial state nearly 14 billion years ago.The big bang theory

The document summarizes the Big Bang theory, which proposes that the universe began approximately 13-15 billion years ago from the violent expansion of space-time known as the Big Bang. It describes how initially the universe was very hot and dense but expanded and cooled over time, allowing the formation of subatomic particles, stars, and galaxies. It discusses evidence that supports the Big Bang theory, such as the discovery of cosmic microwave background radiation and abundances of light elements found throughout the universe.The Big Bang Theory

The document summarizes the history and development of the Big Bang theory. It describes how discoveries in astronomy and physics have shown that the universe started approximately 13.8 billion years ago from an infinitely dense and hot singularity. It then explains the three phases of the early universe and some of the scientists like Einstein, Friedman, Hubble, and Lema樽tre who contributed to establishing the theory. Finally, it discusses some evidence that supports the Big Bang theory like the discovery of the cosmic microwave background radiation and some continuing problems and areas of research.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.Big Bang Theorychandler

The Big Bang Theory attempts to explain how the universe was created around 13.8 billion years ago from an infinitely dense and hot singularity. It holds that all matter in the observable universe was compressed into a tiny point that began rapidly expanding and cooling. Two key scientists who developed it were Hubble and Lemaitre. Black holes are theorized to be the power behind the Big Bang, as their intense gravity can compress matter into a single point, and could trigger another "Big Bang" by consuming all matter into a single black hole that causes re-expansion. The theory remains controversial on questions like what caused or predated the initial expansion.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 distanceCreation 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.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.The Big Bang

The Big Bang theory proposes that the universe began around 13.7 billion years ago as a tiny, infinitely dense point that exploded outward. It then rapidly expanded and cooled over the next few minutes, forming the light atoms of hydrogen and helium. Over millions of years, gravity caused matter to accumulate into galaxies, stars, and other celestial bodies. Predictions of the Big Bang theory have been confirmed by observations that galaxies are moving away from each other, the discovery of cosmic microwave background radiation, and the composition of the universe matching what would be expected from a hot, dense initial state. The universe continues to expand today.Theories of the creation of the universe

The document discusses several theories about the origin and creation of the universe:
1) A higher power or super-scientient created everything using skills and knowledge beyond our own understanding.
2) Ancient Greeks and Romans believed their gods emerged and created the world, though their understanding was limited.
3) Some early cultures believed the universe was created by water serpents or heaven dwellers.
4) Christianity teaches that God created the universe in seven days, though different sects disagree on the timeline.

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.Big bang theory2

The Big Bang theory proposes that the universe began approximately 13.7 billion years ago from the violent expansion of space and time starting from a state of extreme density and high temperature. Evidence for this theory includes the expansion of the universe, the cosmic microwave background radiation, and the relative abundance of light elements like hydrogen and helium. The theory is supported by observations from the COBE satellite which mapped the cosmic microwave background radiation and provided insights into the early universe shortly after the Big Bang. There are several hypotheses for the long-term future of the universe depending on whether its overall density exceeds or falls below the critical density level.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.Big Bang

The document discusses different theories about the origin and creation of the universe throughout history. It begins with what the ancient Greeks believed, which was that the Earth was the center of the universe. It then explains the modern Big Bang theory, which suggests the universe began roughly 13.7 billion years ago from an infinitely dense, hot explosion. The document considers what the universe might be like if the Greek view was correct and the Earth was at the center, concluding that the Big Bang theory currently provides the most accurate explanation.01a 0 is_there_god

This document discusses arguments for the existence of God. It begins by stating that human reason allows for only two explanations for the origin of the world: either something has always existed or nothing existed at some point. Since nothing cannot become something, the author argues we must assume something has always existed, and that something is God. The document then discusses different views people have on faith and creation, including theist, atheist, agnostic, theistic evolutionist, and Christian views.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.the-bigbang-theory

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.thebigbangtheory-59725464

Christians often feel intimidated when talking to others about creation--not because they doubt creation but because most of academia doubts it. Feel that way no longer! The chapter discusses, in simple language, the logic behind creation and the irrational thought those who doubt creatoin must accept live with.Ellemer Rose_Earth and Life Science Lesson 1.pdf

Nothing at the Cosmic Beginning?
Is the creation of something from nothing (creatio ex nihilo) biblical?
Priest George Lemaitre, using Einsteins general relativity, predicted the beginning was a miniscule, hot big bang. Radio astronomers have measured the cool fossil radiation from this hot beginning.
MIT Prof. Guths inflationary cosmology refined with Lemaitres prediction. Guths answer to what was there at the beginning is the laws of physics. In the beginning was the word, or logos (John 1.1).

The Big Bang theory proposes that the universe began approximately 13.8 billion years ago from the explosion of a single point that contained all matter. As this primeval atom exploded it formed the basic building blocks of atoms like hydrogen and helium. Over billions of years, gravity caused these atoms to form stars and galaxies which eventually led to the formation of planets, and eventually life. Evidence for the Big Bang includes the cosmic microwave background radiation and the redshifting of light from distant galaxies indicating an expanding universe. While largely accepted, some questions remain about what caused the initial explosion and conditions in the early universe.The Cosmological Argument
The Cosmological ArgumentEllenLesser
油
The document summarizes arguments for and against the cosmological argument. It presents the cosmological argument, which claims that everything that exists has a cause, the universe exists, therefore the universe must have a cause (God). It then discusses several objections, such as whether the universe truly had a beginning, Russell's argument that quantum events appear uncaused, and that the jump from a cause to God is unwarranted. The document also considers responses to these objections.

Protein degradation via ubiquitous pathway In general science, a ubiquitous pathway refers to a biochemical or metabolic pathway that is:
1. *Widely present*: Found in many different organisms, tissues, or cells.
2. *Conserved*: Remains relatively unchanged across different species or contexts.
Examples of ubiquitous pathways include:
1. *Glycolysis*: The process of breaking down glucose for energy, found in nearly all living organisms.
2. *Citric acid cycle (Krebs cycle)*: A key metabolic pathway involved in energy production, present in many cells.
3. *Pentose phosphate pathway*: A metabolic pathway involved in energy production and antioxidant defenses, found in many organisms.
These pathways are essential for life and have been conserved across evolution, highlighting their importance for cellular function and survival.

We investigate how localization precision and the depth of optical imaging affect host association and discuss the implications of such a low-luminosity dwarf galaxy. Unlike the other repeaters with low-luminosity hosts, FRB 20190208A has a modest Faraday rotation measure of a few tens of rad m2, and EVN plus Very Large Array observations reveal no associated compact persistent radio source. We also monitored FRB20190208A for 40.4hr over 2yr as part of the Extragalactic Coherent Light from Astrophysical Transients repeating FRB monitoring campaign on the Nan巽ay Radio Telescope and detected one burst. Our results demonstrate that, in some cases, the robust association of an FRB with a host galaxy will require both high localization precision and deep optical follow-up.

The Solar Systems passage through the Radcliffe wave during the middle MioceneS辿rgio Sacani
油
As the Solar System orbits the Milky Way, it encounters various Galactic environments, including dense regions of the
interstellar medium (ISM). These encounters can compress the heliosphere, exposing parts of the Solar System to the ISM, while also
increasing the influx of interstellar dust into the Solar System and Earths atmosphere. The discovery of new Galactic structures, such
as the Radcliffe wave, raises the question of whether the Sun has encountered any of them.
Aims. The present study investigates the potential passage of the Solar System through the Radcliffe wave gas structure over the past
30 million years (Myr).
Methods. We used a sample of 56 high-quality, young (30 Myr) open clusters associated with a region of interest of the Radcliffe
wave to trace its motion back and investigate a potential crossing with the Solar Systems past orbit.
Results. We find that the Solar Systems trajectory intersected the Radcliffe wave in the Orion region. We have constrained the timing
of this event to between 18.2 and 11.5 Myr ago, with the closest approach occurring between 14.8 and 12.4 Myr ago. Notably, this
period coincides with the Middle Miocene climate transition on Earth, providing an interdisciplinary link with paleoclimatology. The
potential impact of the crossing of the Radcliffe wave on the climate on Earth is estimated. This crossing could also lead to anomalies
in radionuclide abundances, which is an important research topic in the field of geology and nuclear astrophysics.

The big bang theory
- 1. THE BIG BANG THEORY Patricia C. Persia 11-Albert Einstein
- 2. The Big Bang theory The idea that the Universe was suddenly born and is not infinite.
- 3. This idea was made when Albert Einstein gave us a better understanding about gravity using the Theory of Relativity
- 4. And Edward Hubble discovered that the galaxies are moving apart from one another.
- 5. But what really happened in the Big Bang theory? Was there really a large explosion?
- 6. NO! There was no explosion, rather there was an expansion!
- 7. Approximately 13.8 billion years ago there was an expansion, and from that expansion all things came to be.
- 8. And from that the Universe started to expand from something really small to something large very quickly, since the Universe has no borders it still continues to expand and expand from all around it is just nothing.
- 10. But there are still many questions on how the Big Bang started. And maybe we will never be able to answer them. But one thing is for sure.
- 11. It is that everything as we know it started from it and we will just have to keep exploring.
- 12. Remember, that we are part of the Universe therefore we can say that we maybe the Universes way of experiencing it. So let us keep exploring and experiencing until there are no more questions to ask.
- 13. THANK YOU!!!
