Parallel Universes

This is 2001 BBC Horizon documentary film mostly dealing with string theory, M-theory, supergravity and the existence of parallel universes, each one a bit different from the other, with different histories, different event and different laws of physics, thus assuming that everything will happen somewhere, sometime in some universe. Even the same people exist in multiple universes, where their lives may be drastically different, or may even not exist at all…thus encompassing all the possible universes, all possible realities in one multi-verse.
Participants in the documentary include Michio Kaku and Paul Steinhardt.
