A multiverse (or meta-universe) is the hypothetical set of multiple possible universes (including our universe) that together comprise all of physical reality. The different universes within a multiverse are called parallel universes. The structure of the multiverse, the nature of each universe within it and the relationship between the various constituent universes, depend on the specific multiverse hypothesis considered.

Multiverses have been hypothesized in cosmology, physics, philosophy, theology, and fiction, particularly in science fiction and fantasy. The specific term "multiverse", which was originally coined by William James, was popularized by science fiction author Michael Moorcock. In these contexts, parallel universes are also called "alternate universes", "quantum universes", "parallel worlds", or "alternate realities".

The possibility of many universes raises various scientific, philosophical, and theological questions.

Answer 2

A ton of speculation about the so-called multiverse ==>http://en.wikipedia.org/wiki/Multiverse_(science)

If you're into science-fiction books, James P. Hogan has a new novel on the stands all about the multiverse. It's called "Mission to Minerva" and is packed with hard science, along with lots of stuff that's possible but not proven yet in the real world.

Answer 3

It is hypothesized that there are many universes. They occupy distinct space-time continua and as such cannot be construed as being spatially adjacent at all, i.e. we'll never run into one and we'll never know if they exist.

It is possible that physical constants are variable from one universe to the other making star formation, life, etc. impossible. Our luck can be explained by the anthropic principle.
