Dark matter

  1. Dec 13, 2007 #1
    Why do we think there is a significant amount of Dark Matter in the
    universe?
    a) Descibe at least 3 independent situations which require Dark Matter to understand observations.
    b) Why don’t we think that Dark Matter is baryonic?
    c) What do we think is might be?
