      That’s a tricky question! Probably, yes, but it’s difficult to know.
      Physicists have proposed several forms of “multiverse” (i.e. lots of different universes together) that are each made possible by a different aspect of the laws of physics. The problem is that we don’t yet have a way of testing whether that theory is correct, if a multiverse did exist then it’d be very far away, and so we need to try to come up with new methods to test for the existence of universes that don’t need us to see them.

      Love these questions as they blown my mind as you start thinking about them. I have read a couple of books about this kind of thing and would say the answer is we have no idea but there could be. It is hard to even contemplate what that could mean but it is very exciting to imagine what it would be like to be able to visit other universes, or that a copy of you could be living in one!

      apparently there are currently 5 possible ways this could be
