      A simple answer is we don’t know. Some physicists have proposed that there are big bangs going on all the time and an infinite number of parallel universes.

      But the universe is everything we know and can see. So the problem is: how will we ever know if those other universes actually exist? We may never be able to know that.

      And even if they do exist the physics of them could be completely different! People there might live in 4 dimensions rather than 3!!!
