    Anyone here believe in the multiuniverse? Ours just being one of many?

    It's a theory like many others. I doubt we'll ever find it.....ours alone is too big to big to handle already. Unless the farfetched theories of wormholes etc can come true. It might be science fiction alltogether?

    Until a grand theory of everything is proven I’ll believe in the possibility of anything.

    A good review of multiuniverse theories can be found here, in the Scientific American-
    basically the levels are
    1/ the infinity of possibilities beyond the observable universe;
    2/ the possible other universes that have formed in other separate Big Bangs;
    3/ the Many Worlds Quantum Hypothesis;
    4/ universes based around alternate mathematical possiblities and physics-apparently all possible mathematical relationships may exist in concrete form;
    These are enough to go on with, I think...

    the last one is particularly baffling, I can only personally relate to it by thinking of Olaf Stapleton's Star Maker, the god that made endless cosmoi in endless abstract forms...
    but the rest of the universes are each infinite and infinitely variable as well.

    Well, there is that experiment that has to do with mutiple universes, or at least with the splitting of them. If you fire a photon at a sheet of paper with two parallel (paralell?) slits in it, and put a sheet of film on the other side, the photon will go through one slit but there with be an interference pattern on the film. The conclusion is that the universe splits, and in one the photon goes through slit A, and in the other the photon goes through slit B, and then the two universes rejoin, causing the interference pattern.
    Then there's another idea, that our conciousness is leaping from one universe to the next, and each universe is frozen moment in our lives. I don't believe it for a second, but what the hell, it's an idea.
    Quantum computing is tied up in the existence of multiple universes, so if it does work, then there should be many universes. I don't know how to check if quantum computing is working, or if anyone is even working on making a quantum computer.

    I think that the point of that experement is not to show what you are saying, but to show that light has wave and particle properties. The two slits experement shows it acting as a wave. The pattern projected on to the wall is where the peaks and valleys of the light coming through the two slits meet. Wherever there is one peak and one valley the light is dim or not there, but it is amplified in other parts.

    I don't see how you could fire one photon through two slits.

    Anything is possibly but I dont believe this untill fully proven. I mean hey I liked the show sliders as much as the next guy but this ......I dont think so.

    a better one

    here is a better one......its not that a photon is shot through the slits. any particle going through the slit(s) that is not hit by a photon on the way acts like a wave instead of a particle. because light (photons) brings the "time" state to the particle.
