Parallel Universes (2 of 5)

From a BBC documentary which explores parallel universe theory - that a set of multiple possible universes comprise all of reality. What is a parallel universe? Like an everyday universe it is a region of space-time containing matter, galaxies, stars, planets and living beings. In other words, a parallel universe is similar and possibly even a duplicate of our own universe. Not only in a parallel universe must there be other beings, but these may be human beings who are exact duplicates of ourselves and who are connected to ourselves through mechanisms only explainable using quantum physics concepts.
