      I don’t think anyone knows for sure yet. There are some theories of physics that predict that there are an infinite number of universes, but they haven’t been tested yet (and probably won’t be for a long time, unfortunately, as they are very difficult to test). So it’s possible.

      I don’t know! I don’t think anyone does! There are some theories that exist about other universes, but we need to find a way of testing if other universes exist before we’ll know for sure.

      I would like to, yes! I don’t believe that there is any evidence for this yet but that doesn’t mean that it isn’t true! I would like to believe that there is another (or maybe even many) other universes out there just waiting for us to discover them!

      I think parallel universes are definitely possible. Whether they exist or not is unclear, and it might take a while to find out. In the meantime, there are lots of exciting theories about them and one day we might be able to prove them. So stay tuned!

      The reason why we think they might exist is about probability: Basically, our Universe appears to be very strange, in some sense. It is as if somebody flipped 400 coins and they all landed heads! This is not impossible, but very strange.

      So the idea is that if you have many many parallel universes, and all of them are different, sooner or later you’ll end up with a universe that looks just like ours, even though to us that looks extremely strange (just like the 400 coins all landed heads — if you try long enough, you’ll eventually get the 400 coins all showing heads, but you have to try many many times).

      So how many other universes might there be??? Here’s the number:
      (no, this is NOT a joke!)
