Have you ever wondered
where the universe came from? There have been many theories over
the ages but nobody really knows the answer. The Big Bang Theory
explains how the universe was created based on our current
understanding of physics and astronomy.
It is probable the universe had a definite starting point which
occurred about 13.3 billion years ago. The Big Bang Theory
explains what happened at the point when the universe began and
was formulated by Georges Lemaitre in 1927. He called it the
“hypothesis of the primeval atom”. The term Big Bang Theory was
first used by astronomer Fred Hoyle in a radio interview in
1949. Hoyle used the term Big Bang to try and explain the
difference between his Steady State Model and Lemaitre's theory.
The Big Bang Theory states the universe was created when a
singularity expanded and cooled. A singularity is an infinitely
small, dense and hot something that we believe is found at the
center of a black hole. When the incredibly small, dense and hot
singularity expanded all the matter that was contained within it
expanded into the universe and continues to expand.
