Question

What is the theory in the origin of the universe you agree and disagree explain why.

Answer 1

It is theorized that the universe originated with the Big Bang wherein all the universe was concentrated into a very small space called singularity and in less than a millionth of a second expanded to form the universe today

I don't quite agree with this concept instead I like the multiverse theory according to which the universe was formed by fusion or fission of two separate universes to form our universe
