Multiverse

A multiverse (or meta-universe) is the hypothetical set of multiple possible universes, including the observable universe, which comprise the whole of physical reality. There are several hypotheses which seek to explain the structure of a multiverse, the nature of each universe within it and the relationship between these various constituent universes.
