    Anti-particle is particle that moves back in time ? Jonh Wheeler has an argument about it ?
    Is this really true ?
    How this works ?
    Thanks

    No it is not. Mathematically there are some similarities in some models, but that is all.

    There are a great many "hypothetical ideas" that get lobbed around in science. Almost none of them get beyond the hypothetical stage, but they often attract the attention of amateurs and crackpots and, because many of these ideas sound really cool, they tend to get shared more than the mainstream models and ideas.

    We can make or collect some kinds of antiparticles such as positrons which now have routine applications such as PET scans in hospitals.
    This is obviously not possible if the positrons used have to come from the future, after then scan has been done.

    This part is really true, Arman777... it was a postulate, proposed by John Wheeler to Richard Feynman, alluding to the one-electron universe...[COLOR=#black].[/COLOR] :oldcool:

    So... no need to be sad...[COLOR=#black] [/COLOR]:ok:
