"The multiverse (or meta-universe, metaverse) is the hypothetical set of multiple possible universes (including the one unique universe we are pretty sure we consistently inhabit) that together comprise everything that physically exists: the entirety of space and time, all forms of matter, energy and momentum, and the physical laws and constants that govern them. The term was coined in 1895 by the American philosopher and psychologist William James. The various universes within the multiverse are sometimes called parallel universes."
