The 'Big Bang' is the model for the formation of our Universe in which spacetime, and the matter within it, were created from a cosmic singularity. The model suggests that in the 13.

Now astronomers have found more than 500 galaxies that had formed less than a billion years after the Big Bang. The galaxies appear red on the images as the blue light from their newly formed stars is reddened by the expansion of the Universe.

The sections above are about some observational facts of the universe. Now, we discuss the most widely accepted evolution model of the universe, the Big Bang Theory.
Big Bang Theory: The theory that the Universe began with all matter and energy concentrated to very high density and temperature some 15 billion years ago. The present universe expanded from that epoch and is still expanding.

the theory that suggests that the universe was formed from a single point in space during a cataclysmic explosion about 18 billion years ago. The force of the explosion accounts for the current expansion of the universe.

Big Bang a theory of the creation of the universe from an ultra-compact volume with very high temperatures about 13.7 billion years ago. The ultra-compact volume began expanding and is responsible for the expanding motion we see today.
"Big Bang" - the universe is expanding from some initial configuration of (arbitrarily high) initial density.
BIG BANG THEORY
The big bang theory states that the universe began as a tiny but powerful explosion of space-time roughly 13.7 billion years ago (plus or minus 1 percent).
The Big Bang Theory
During 1948 the Russian-American physicist George Gamow modified Lemaître's theory of the primeval atom into the big bang theory of the origin of the universe.

Most people are familiar with the term 'Big Bang' theory. However when astronomer Sir Fred Hoyle first coined the phrase 'Big Bang' he did so in order to mock the theory.
Big Bang
A broadly accepted theory for the origin and evolution of our universe. The theory says that the observable universe started roughly 13.7 billion years ago from an extremely dense and incredibly hot initial state.

39. Big Bang Theory
The theory that the universe began with a violent explosion from which the expanding universe of galaxies formed.
As a result of the Big Bang (the tremendous explosion which is thought to have marked the beginning of our Universe), the universe is expanding and most of the galaxies within it are moving away from each other.

the big bang and steady state theories, have been formulated (see cosmology). Albert Einstein's theory of relativity plays a central role in all modern cosmological theories.
During the early phases of the Big Bang, nucleosynthesis of hydrogen nuclei resulted in the production of hydrogen and helium isotopes, as well as very minuscule amounts (on the order of 10-10) of lithium and beryllium.
Observations show that the galaxies in the universe are on average moving away from one another; this is the motivation for the Big Bang theory of cosmology.
What Could Have Powered the Big Bang?
Scientists think that the universe is almost 14 billion years old. There are different theories for how the universe began. The big-bang theory says that it began when a tiny but dense mass of energy exploded.
George Gamow (March 4, 1904-Aug. 19, 1968) was a nuclear physicist, cosmologist, and writer who formulated the Big Bang Theory (with Ralph Alpher in 1948), worked on quantum theory, stellar evolution, ...
The term "Primordial Nucleosynthesis" refers to the production of chemical elements with more than one proton a few moments after the Big Bang.
The theory that best explains the current universe is the Big Bang theory. This theory states that, in the beginning, the universe was all in one place. All of its matter and energy were squished into an infinitely small point, a singularity.
Some 12 or 15 billion years ago, after the energy created by the "Big Bang" had cooled forming matter, the universe was 75 percent hydrogen, nearly 25 percent helium, and one part in 10,000 lithium.

Hawking (1971) proposed that early after the Big Bang, mini-black holes existed, obeying quantum-mechanical laws due to their sub-atomic size. Hawking (1974) hypothesized that black holes emit subatomic particles until they explode.
