How can one thing be in 2 places at once?

From my understanding, the Quantum theory supports the idea of parallel universes. It suggests that when i make the decision to sit here and type this and ask it to the TED community, there is another "me" in different dimension that is not doing that....in fact, he is probably not a fan of TED community to begin with and is probably kicking a soccer ball in his bedroom or something. I want to hear the TED community's reaction to this notion.

  • Aug 4 2012: There is a difference between “string theory” or “brane theory” and the dimensions that they suppose exist and “parallel universes”. String theory believes there are different dimensions that we cannot perceive but that isn’t to say that they are other three dimensional spaces like we live in they are just in addition to our three(or four) that we understand.
    “Parallel universes” typically suppose an infinite universe where there is an infinite number of stare. An infinite number of stars is going to have an infinite number of stars like the sun. An infinite number of “sun” stars are going to have an infinite number of “earths”. Every possible event that could occur, would occur on that infinite number of “earths”. So when ever any possible action A occurs there are infinite other “earths” where B occurs. If you look back through time at all the possible A or B occurrences there are infinite number of ways that things that could have happened and with infinite “earths” on some A happened and some B happened.
    But those other people on other earths that are identical to you in every way, are no more “you” than a set of twins are the same person. If you could travel the distance to another earth you could meet “you”.

      Aug 5 2012: Hmmm....thanks for that :) I have never thought of or been introduced to "brane theory", i will have to look into it. Any books you would recommend?

        Aug 5 2012: Warped Passages by Lisa Randall. She is, I believe, the originator of the theory of branes and writes about them, as well as about string theory and multiple dimensions in that recent book for the layperson, which probably came out in 2007. She is in the physics department at Harvard.
        • Aug 5 2012: I also like Dr Michio Kaku’s "Strings, Conformal Fields, and M-Theory". M-theory is short for membrane theory, which is the same as brane theory(what it was called the first time I read about it). Essentially it is string theory but with added dimensions… Oops, was I supposed to say “spoiler alert” first?
