I have thus far read a couple of books which have multiverses in them. I was wondering if there are any others out there so I am creating this list in the hopes of discovering more. According to Wikipedia, '"The multiverse (or meta-universe) is the hypothetical set of finite and infinite possible universes, including the universe in which we live. Together, these universes comprise everything that exists: the entirety of space, time, matter, energy, and the physical laws and constants that describe them.
The various universes within the multiverse are called "parallel universes", "other universes" or "alternate universes."'
