Singularity problem

  1. Jan 7, 2008 #1
    I'm trying to figure out how scientists concluded that all matter in the universe was compressed to the size of something smaller than an atom. If thats true than I think the there has to be undiscovered particles several folds smaller that the smallest known particle today. Particles so small that if you increased their size to the size of an atom then the size of an atom would as big as our solar system. I wouldn't be suprised if they were shrinking at the same rate in which our universe is expanding.

    The general assumption is that right after the big bang the universe was made up of energy. Matter was created while the early expansion took place from photon-photon reactions.
