The TV show "Sliders"(from one concurrent universe to another) was either beyond its time or to early for it..
It appears Americans are getting stupider.. and the Sliders meme window is closed.. Quantum mechanics work on cars these days..
That "possibility" (of multiverses) certainly simplifies choice. It will not matter. For instance, I encourage all Obama supporters to not vote since Obama will win, somewhere. Maybe even here since seeing that the Obama supporters might have something up their sleeves, the McCain supporters will also not vote. But then this might be the multiverse where the necessary molecules just happen to gather in one spot and form Ronald Reagan again and seeing this event occur the single voter in each state will write in Ronald Reagan and he will be the President again. Ah, but he must be reformed within the territory of the United States to be eligible.
But then again, this may be the multiverse in which some clever scientist proves that there are not multiverses.
etc.

Ad infinitum. Does the list of all lists that do not contain their own names contain its own name? ala K. Göedel
