Since the early part of the 1900s, one explanation of the origin and fate of the universe, the Big Bang theory, has dominated the discussion. Proponents of the Big Bang maintain that, between 13 billion and 15 billion years ago, all the matter and energy in the known cosmos was crammed into a tiny, compact point. In fact, according to this theory, matter and energy back then was the same thing, and it was impossible to distinguish one from the other.
Adherents of the Big Bang believe that this small but incredibly dense point of primitive matter exploded. Within seconds the fireball ejected matter at velocities at the high speed. At some later time all of the different elements in the universe started to creation.
Big Bang theorists claim that all of the galaxies, stars, and planets still retain the explosive motion of the moment of creation and are moving away from each other at great speed. This supposition came from an unusual finding about our neighboring galaxies. In 1929 astronomer Edwin Hubble, working at the Mount Wilson Observatory in California, announced that all of the galaxies he had observed were receding from us, and from each other, at speeds of up to several thousand miles per second .
These are all things which have been studied by scientists until the time of the Big Bang, but no logical explanation has been given by them for before the Big Bang. In this article, we provide an overview of what happened before the Big Bang.
