It has been theorized before that if there is infinite universes, then there is infinite possibilities of what could exist. So anything anyone has ever imagined could be real somewhere. Think of a multiverse, infinite universes expanding and contracting all next to each other, like individual little atoms within something infinitely larger. Possibly even different laws of physics, maybe completely different fundamental forces controlling everything. Although I'm going off on a whole other tangent here... Can't help it sometimes...
