Parallel Universes Go Legit

One of the fun things about physics is the strange things predicted by Quantum Mechanics. For example, the idea that a particle can move from point A to point B without ever occupying the space in between. Or the idea that an object can be in multiple states (i.e. dead and not dead) simultaneously. But one of the strangest predictions of Quantum Mechanics has to be the Star Trek-esque idea that everytime you make a choice, the universe splits into two parallel universes in which you make each choice. For years, people have made fun of this idea. But now, it appears that the idea is not so crazy. Lazy sci fi writers, have at it!
