This leads to the question of why the formation of matter after the Big Bang resulted in a universe consisting almost entirely of matter, rather than being a half-and-half mixture of matter and antimatter.

In this theory, the remote future of the previous aeons becomes the Big Bang of subsequent aeons.

He especially tried to explain the baryon asymmetry of the universe, being the first scientist to introduce two universes called " sheets ", linked by the Big Bang.

According to the Big Bang model, the Universe expanded from an extremely dense and hot state and continues to expand today.

The Big Bang theory is the prevailing cosmological model that describes the early development of the Universe.

According to the Big Bang theory, the Universe was once in an extremely hot and dense state which expanded rapidly.

According to the most recent measurements and observations, the Big Bang occurred approximately 13. 75 billion years ago, which is thus considered the age of the Universe.

While protons and neutrons combined to form the first atomic nuclei only a few minutes after the Big Bang, it would take thousands of years for electrons to combine with them and create electrically neutral atoms.

The Big Bang is a well-tested scientific theory and is widely accepted within the scientific community.

The core ideas of the Big Bang — the expansion, the early hot state, the formation of helium, and the formation of galaxies — are derived from many observations that are independent from any cosmological model ; these include the abundance of light elements, the cosmic microwave background, large scale structure, and the Hubble diagram for Type Ia supernovae.

Thus, the Big Bang theory cannot and does not provide any explanation for such an initial condition ; rather, it describes and explains the general evolution of the universe going forward from that point on.

Georges Lemaître first proposed what would become the Big Bang theory in what he called his " hypothesis of the primeval atom.

The framework for the Big Bang model relies on Albert Einstein's general relativity and on simplifying assumptions such as homogeneity and isotropy of space.

While the scientific community was once divided between supporters of the Big Bang and those of alternative cosmological models, most scientists became convinced that some version of the Big Bang scenario best fit observations after the discovery of the cosmic microwave background radiation in 1964, and especially when its spectrum ( i. e., the amount of radiation measured at each wavelength ) was found to match that of thermal radiation from a black body.

This singularity is sometimes called " the Big Bang ", but the term can also refer to the early hot, dense phase itself, which can be considered the " birth " of our Universe.

The earliest phases of the Big Bang are subject to much speculation.

A few minutes into the expansion, when the temperature was about a billion ( one thousand million ; 10 < sup > 9 </ sup >; SI prefix giga -) kelvin and the density was about that of air, neutrons combined with protons to form the Universe's deuterium and helium nuclei in a process called Big Bang nucleosynthesis.

Also, general relativity has passed stringent tests on the scale of the Solar System and binary stars while extrapolation to cosmological scales has been validated by the empirical successes of various aspects of the Big Bang theory.

The Big Bang is not an explosion of matter moving outward to fill an empty universe.

An important feature of the Big Bang spacetime is the presence of horizons.

Fred Hoyle is credited with coining the term Big Bang during a 1949 radio broadcast.

The Big Bang theory developed from observations of the structure of the Universe and from theoretical considerations.

In the 1920s and 1930s almost every major cosmologist preferred an eternal steady state Universe, and several complained that the beginning of time implied by the Big Bang imported religious concepts into physics ; this objection was later repeated by supporters of the steady state theory.

This perception was enhanced by the fact that the originator of the Big Bang theory, Monsignor Georges Lemaître, was a Roman Catholic priest.

The other was Lemaître's Big Bang theory, advocated and developed by George Gamow, who introduced big bang nucleosynthesis ( BBN ) and whose associates, Ralph Alpher and Robert Herman, predicted the cosmic microwave background radiation ( CMB ).

The discovery and confirmation of the cosmic microwave background radiation in 1964 secured the Big Bang as the best theory of the origin and evolution of the cosmos.

Much of the current work in cosmology includes understanding how galaxies form in the context of the Big Bang, understanding the physics of the Universe at earlier and earlier times, and reconciling observations with the basic theory.

The earliest and most direct kinds of observational evidence are the Hubble-type expansion seen in the redshifts of galaxies, the detailed measurements of the cosmic microwave background, the relative abundances of light elements produced by Big Bang nucleosynthesis, and today also the large scale distribution and apparent evolution of galaxies predicted to occur due to gravitational growth of structure in the standard theory.

These are sometimes called " the four pillars of the Big Bang theory ".

Inflation and baryogenesis remain more speculative features of current Big Bang models: they explain important features of the early universe, but could be replaced by alternative ideas without affecting the rest of the theory.

As a theory relevant to the origin of the universe, the Big Bang has significant bearing on religion and philosophy.

Some researchers still advocate a handful of alternative cosmologies ; however, cosmologists generally agree that the Big Bang theory best explains observations.

One was Lemaître's Big Bang theory, advocated and developed by George Gamow.

Therefore, while the basic features of this epoch have been worked out in the Big Bang theory, the details are largely based on educated guesses.

Big Bang Nucleosynthesis is the theory of the formation of the elements in the early universe.

It was used for many years as a probe of physics at the time of the Big Bang, as the theory of Big Bang nucleosynthesis connects the abundances of primordial light elements with the features of the early universe.

In light of the Big Bang theory, a stylized version of argument has emerged ( sometimes called the Kalam cosmological argument, the following form of which was created by Al-Gazali and then strongly supported by William Lane Craig ):

`` A fat hell on Big Hans.

`` A fat hell on Big Hans.

`` He said a fat hell on Big Hans ''.

`` He said a fat hell on Big Hans ''.

but they were going up to the Big House after supper, and she had to put on a clean dress and fix her hair a little.

When the Korean war began, on June 25, 1950, the anniversary of the day Custer had gone down fighting at the Little Big Horn and the day the regiment had assaulted the beachhead of Leyte during World War 2,, the 7th Cavalry was not in the best fighting condition.

To help him on this religious aspect of primitive jazz he had `` Big '' Miller, as a preacher-singer and Hannah Dean, Gospel-singer, while Oscar Brown Jr., an extremely talented young man, did a slave auctioneer's call, a field-hands' work song, and a beautifully sung Negro lullaby, `` Brown Baby '', which was one of the truly moving moments of the festival.

In " The Big Four " ( 1927 ) Poirot feigned his death and subsequent funeral in order to launch a surprise attack on the Big Four.

Big business is not taxed in proportion to its capacity and output, and the disproportionate burden falls on small and medium size businesses.

She has referenced this independence from major labels in song more than once, including " The Million You Never Made " ( Not A Pretty Girl ), which discusses the act of turning down a lucrative contract, " The Next Big Thing " ( Not So Soft ), which describes an imagined meeting with a label head-hunter who evaluates the singer based on her looks, and " Napoleon " ( Dilate ), which sympathizes sarcastically with an unnamed friend who did sign with a label.

The album was a multi-platinum success and produced the pop hit " Lucky One " ( No. 18 pop and No. 2 AC ; No. 1 on Radio & Records ) as well as the title track ( a duet with country music star and future husband Vince Gill ) ( No. 37 pop ) and a cover of Joni Mitchell's frequently covered " Big Yellow Taxi " ( No. 67 pop ) ( in which she changed the line " And they charged the people a dollar and a half just to see em " to " And then they charged the people 25 bucks just to see em ").
