Questions on the universe

  1. Dec 3, 2007 #1
    Sorry, I don't know where to post this one -

    Could we detect other universes where the laws of physics are not the same as ours? If there was another universe could we visit it or send anything? Would it be 'compatible'?

    Could the universe have been created from a type of antimatter explosion?

    If there are multiple universes, are these other dimensions or is that different?

    Try in cosmology, i think some one said that effect of other Us on ours could be detected,
    but cosmology is the place.

    Cosmology, yeah, good place to start I guess.
