Multiverse

Scientists speculate that ours might not be the only universe out there — we might instead live in a set of infinite universes called a "multiverse". Infinite universes are a consequence of several scientific theories; for instance, if spacetime truly goes on forever it might start repeating eventually, since particles can only be arranged a finite number of ways. A multiverse could also arise from "bubble universes," pockets of space in an inflating universe that are never able to meet; or parallel universes, where multiple 3D universes are held in higher-dimensional space, unable to interact. While some universes in a multiverse might be like our own, others could have wildly different laws of physics and fundamental constants.
