Big Bang Theory
All matter that makes up our Universe originated from a single point- a very small dense
and very hot point called a singularity.
An explosive event caused matter from the singularity to spread out, forming the
Universe that we exhibit today.
This is the Big Bang Theory which is the currently accepted model of the Universe.
