Unsolved problems in astrophysics

  1. Feb 15, 2009 #1
    so what are some simple unsolved problems in astrophysics, that are interesting. could someone just list some topics out? I've been researching on the interwebz, but can't seem to find a topic that is interesting/simple.
    also are there any such topics related to newtonian mechanics/electricity and magnetism?
    I don't have a really advanced background in physics, as I am only taking an introductory college course.

    bump. specifically, I'm interested in the shape and origin of the Universe.
    how can knot theory explain the shape of the Universe? specific info would be helpful. thanks!
