Distribution and proportion of dark matter in galaxies

  1. Mar 27, 2010 #1
    I read that the distribution and proportion of dark matter to regular matter is different for regular-size galaxies and dwarf galaxies. Could you guys elaborate on that?

    the theory is that dark matter could cover 99 percent of our universe, but today i don't think we know much about it relative to regular matter.

    I thought it covered 96%

    It could be a lot less depending on how innaccurate our theories are.

    We don't really know for sure how gravity works on larger scales.
