  Very good question!
  The short answer is: no one knows. There is a theory called the “multiverse”, which suggests there are multiple Universes. I like to believe this is true 🙂
  However, it is extremely difficult to prove this! There are some ideas of experiments we could carry out that may tell us whether other Universes have interacted (or “touched”) our own which is super cool!
  
  Even if there were other universes I’m not sure we would be able to travel between them though.
