Big Bang Theory

There are so many number of questions like how this universe
came into existence and what form is it going to be in future
always keeps bothering our scholars and scientists and thus in
sake of finding answers to which they every time come up with
some new theory that can prove out to be perfectly answerable
to their queries.
And so like many other theories, big bang is also the one
which describes about how this universe, that you are living in
now, came into existence. Though, this is not that only theory
which described about whole of the universe, but among many
of those such as Steady State Theory or Oscillating universe
theory, this was the one which was highly accepted and thus
became popular.
This is the theory which made people believe that there was
nothing before this universe that could be of help to make all
this happen and then there was everything that you are living
in after that great explosion. It was actually brought up in light
by the scientist named as Friedrich Franz Friedmann who with
those many of his field equations claimed that the universe is
expanding.
After which the Roman Catholicpriest and physicist George
Lemaitre in 1927 again suggested that the planet is expanding
which was finally proved by Edwin Hubble through his
discoveries. Moving ahead with which the discovery of cosmic
microwave radiation in 1965 actually made this theory proved
as best of all which indicates about how universe actually
originated.
