- Multiverse (Wikipedia)
The multiverse is a hypothetical group of multiple universes. Together, these universes are presumed to comprise everything that exists: the entirety of space, time, matter, energy, information, and the physical laws and constants that describe them. The different universes within the multiverse are called “parallel universes”, “other universes”, “alternate universes”, or “many worlds”. One common assumption is that the multiverse is a “patchwork quilt of separate universes all bound by the same laws of physics.”
