The Big Bang Theory is the dominant scientific theory about the origin of the universe. According to the big bang, the universe was created sometime between 10 billion and 20 billion years ago from a cosmic explosion that hurled matter and in all directions.
In 1927, the Belgian priest Georges Lemaître was the first to propose that the universe began with the explosion of a primeval atom. His proposal came after observing the red shift in distant nebulas by astronomers to a model of the universe based on relativity. Years later, Edwin Hubble found experimental evidence to help justify Lemaître's theory. He found that distant galaxies in every direction are going away from us with speeds proportional to their distance.
The big bang was initially suggested because it explains why distant galaxies are traveling away from us at great speeds. The theory also predicts the existence of cosmic background radiation (the glow left over from the explosion itself). The Big Bang Theory received its strongest confirmation when this radiation was discovered in 1964 by Arno Penzias and Robert Wilson, who later won the Nobel Prize for this discovery.
Although the Big Bang Theory is widely accepted, it probably will never be proved; consequentially, leaving a number of tough, unanswered questions.

To matt o-
If you read most science books the first chapter will tell you there are no facts in science. However, the second chapter will tell you that evolution and the big bang theory are facts. If you exam the evidence you will find that evolution and the big bang take more faith than creation to believe in. They are theories and can not be proven. In order for the Big Bang to have taken place, every law of nature (and the laws of thermodynamics) would have had to be broken. Also, evolution is in direct conflict with the law, "Everything tends toward decay."

The theory in short is that the substance of the universe existed at a single point, the primeval atom which then exploded outwards. In the explosion the structure of space time and the setting of the current physical laws occurred. The explosion is still happening as space is expanding (as seen by red blue shift). It is thought that either it will continue to expand or start to fall in on itself. If it falls in on itself another big bang could occur creating a new universe with different laws and matter.

In physical cosmology, the Big Bang is the scientific theory of how the universe emerged from a tremendously dense and hot state about 13.7 billion years ago
The theory is based on the observations indicating the expansion of space (in accord with the Friedmann-Lemaître model of general relativity) as indicated by the Hubble redshift of distant galaxies taken together with the cosmological principle.

Basically, the big bang theory states that in the beginning (about 13,700 million years ago), matter was very concentrated and that, following an explosion (the big bang), matter was strewn outwards to form galaxies and other astronomical entities. Supposedly, some quasars may remain from the original big bang.

One day, long ago, two fairy clans were at the annual fairy convention. Such a tadoo ensued as one of the elders got his wing trapped in a sliding door. Magic was everywhere and it got rather out of control. The universe was full of magicness and fairy flutterings. Bang! And boy was it a big one. Star dust everywhere and several worlds collided. Hope that helps, thank you for asking. x

If there was a big bang 20 million years ago shouldn't there be a big hollow in the middle with nothing in it or is it still banging?

first there was the big crunch, where everything in the universe comes together and forms nothingness... then that nothingness has too much mass or something like that..and then there was a big bang and everything scattered all over the place

read a book of fact not fiction . big bang aint a theory, its a fact. the book will tell you what it actually is.
