Single electron and infinite universes
« on: 08/06/2009 20:29:26 »
Today, on Dr Karl, I heard that there is a single, unique electron in the universe.

I also heard that there are an infinite number of universes.

So, does each universe have its own electron or is it the same one in all of the universes?

The single electron theory was something Feynman came up with as a description of quantum mechanics, but has since been somewhat discounted, since it can't explain why matter is more prevalent than antimatter.  (My source for this one is Wikipedia, since I haven't heard of this theory much in mainstream physics). 

You'll have to be more specific about the multiple universe theory, but the most common one is the many-worlds interpretation of quantum mechanics.  This is another explanation of the weirdness of quantum mechanics, but it hasn't been discounted.

I think this might come from a whimsical statement by Richard Feynman that the universe only consists of one electron. It travels forward in time as an electron and backward in time as a positron and we in the present only see the many passings of that one electron. I don't think it was ever a serious proposition.
