Big-Bang pretty much explain the origin of universe, but still many people don't believe it. Isn't it possible that our universe come out of a white hole which have been pulled out from a black hole that was in some other universe?

  • $\begingroup$ By "formation" do you mean "origin" or "the development of the structure that we see today"? Those are two different things, and will elicit different answers. $\endgroup$ – garyp Jul 18 '16 at 17:43
  • $\begingroup$ I mean the origin (how it was created). $\endgroup$ – Vishnu JK Jul 18 '16 at 17:45
  • $\begingroup$ why you didnt consider that black hole was pulled out of another black hole which was pulled out of a white hole? $\endgroup$ – user122089 Jul 18 '16 at 17:49

No one knows.

One other thing ... the big bang hypothesis does not explain the origin of the universe (although I recognize that you used the word "formation", not "origin", but I'm not sure what exactly you meant by "formation"). It explains what happens after a certain epoch in our universe's history. What happens before that is completely unknown. What we call the big bang might occur a tiny fraction of a second before the creation of the universe, or many billions of years after the creation of the universe. All that assuming that the universe had a creation event.
