The Many-Worlds Theory.

Anyone familiar with this one?
The Idea of Parallel Universes, or "worlds" coexisting with our own, each seperate, but similar.
One of my personal favorite Theories.
And I'm pretty sure it's Quantum Physics, or Mechanics, one of the two, which just makes it more awesome, lol.
Dean Koontz wrote a book utilizing the Idea, which got me started in it.
From The Corner Of His Eye.
Amazing.
What're some of yours?
What do you think of the Theory?

I think it's definately a possibility. I mean, we can't be the only life-inhabited planet or vast universe out there. Maybe the only one exactly like ours, but definately not the only one.

Of course, It'd be kind of ignorant, and self centered, to believe that we're the ONLY living things, in this vast universe.

And parallel universes? Of course!
Can you prove it wrong?
