      … only in Marvel world .. as far as we know!

      Really good question and there is not a clear answer. At the moment it is just a theory, so just an idea, but no experiment to prove it yet. I think it makes a lot of sense, but how would you show that it exists?
      Also (I am not sure if you know), there are two versions of the multiverse:
      1. The one used in movies (like the Marvel Multiverse): Basically it is multiple Worlds overlapping were all things happen at once, but we only experience one of them.
      Or
      2. Our Universe is basically a huge bubble that keeps growing and growing. But what is outside of this bubble? Maybe another bubble next to it? Maybe 100s? 10000s? These would all be other universe-bubbles. so in total a Multiverse.
      I think the second version makes a lot more sense, but again, both are really difficult to show in an experiment… maybe even impossible.

      Nobody knows! Some scientists think so, others don’t, but nobody has been able to prove it… yet! It would be an exciting time to study physics and find this out though 🙂

      The really cool thing about science is there is loads of stuff we don’t yet know, such as whether or not there is a multiverse! It is a theory which some scientists are exploring, but nobody has proved it yet. It is still a question to be further explored

      Multiverses are a theoretical physics idea that try to explain some aspects of what we do not yet know (they are also a way for some people to publish lots of speculative papers with no real physics in them). For me, this goes against Occam’s razor (that the simplest explanation is usually correct) in that there appears to be lots of ideas stuck into this big idea and that should make one immediately suspicious. I suspect we have a long way to go on this and a more natural and simpler idea will eventually be proposed.
