Is there such a thing as a parallel universe?
There could be parallel universes. Some explanations of the paradoxes
of time travel (which we also don't know if it's possible yet) use the existence
of parallel universes to solve the problem, and some interpretations of quantum
mechanics (the fundamental theory that explains how atoms and electrons behave) also suggest
that parallel universes exist. So far, however, nobody really knows any way of
going from our universe to another one, so it's really hard to prove or disprove
any of these theories!
