The critically-acclaimed board game
MooT
consists of tough questions about the nuances of the English language.
Answer:
multiverse
According to the Caltech
Knowledge-base for Extragalactic Astronomy and Cosmology ?
http://nedwww.ipac.caltech.edu/level5/ ? the word
multiverse denotes a: Hypothetical enlargement of the cosmos in which our Universe is
but one of an enormous number of separate and distinct Universes.
If you think about it, the neologism
multiverse introduces some cosmological
cognitive dissonance. Doesn't the word Universe denote: "all that there is." Thus a
multiverse being another universe is another "all that there is."
A complete explanation of the term multiverse and its etymology can
be found in the Wikipedia at: http://www.wikipedia.org/wiki/Multiverse
