Why Parallel Universes?

I agree with 1.618 here.There are some very bizarre behaviours of matter at the quantum level. Attempts to explain these behaviours has led to a lot of speculation. Basically anything that can't be ruled out is conjectured as an explanation for what is going on.I don't think the scientists do think that parallel universes exist or think that they don't exist it is simply a speculation about why quantum behaviour is so weird. They can't be tested (as far as I know) so they remain speculations.There have been objections to some of the "explanations" behind QM before. Einstein, for example, objected to "spooky action at a distance". However, it turned out, decades later, that tests could be done on this speculation and he was wrong. Now we have suggestions of using this effect for computing.Will parallel universes go through the same stages? Dammed if I know.

You can't go back in time. And you don't have to. The speculation is that the other universe with the other avatar exists. When you made your avatar decision the two universes split and one had Jesus and one Mosus.(added by edit)
Though in fact this is NOT exactly what the idea is suggesting. Unless your decision is a QM event in some way that kind of difference isn't what splits the universes. But then I guess there are QM events going on in how your think. That is part of the suggestions of R. Penrose as to why we will never get AI. (I think he's wrong btw).This message has been edited by NosyNed, 07-12-2004 10:01 PM
