…and George W. Bush is just the Comissioner of Baseball…or, at least, these are among the possibilities that some leading physicists postulate might live among an infinite number of parallel universes.
A recent episode of The History Channel's "The Universe" series explores the same concepts that we dance around here in our own "Parallel Universe of T. Townsend Brown." You can view the episode in short videos online.
The argument is presented that even the word "universe" is obsolete in cosmological terms, because the root "uni" means "one." So, now it's the "multiverse." Or maybe it's the "megaverse." Or the "infiniverse." Take your pick. Just, please, don't let George W. Bush be president in any of them. Come to think of it "Commissioner of Baseball" is probably over his head, too.
