Big bang 2?

  1. Mar 10, 2005 #1
    if matter and anti-matter are highly explosive when they collide, then how come there hasn't been a second big bang???

    where has all the anti-matter gone, if there were equal amounts for the big bang, then why is there matter, but apparantly no anti-matter

    sorry if i got something wrong here

    The conclusion that there are no large amounts of antimatter in the observable universe is that, if we assume the contrary, chances are we would have seen some kind of effects of annihilation from time to time. Although, from my understanding of the explanation, it is assuming alot.

    Because most of the antimatter is in between the places with concentrations of matter - the expanses between galaxies
