Gravitational Lensing
  • Gravity distort light, dark matter has gravity
  • We see distorted version of galaxy behind dark
    matter
  • Roughly see where it is

Neutrino vs. WIMP
  • Thought to be dark matter
  • Very fast - hot
  • Neutral
  • Interact weakly
  • Theory rejected
  • Weakly interacting
  • Move slow - cold
  • Most people believe to be dark matter

Mining The Heavens
  • Soudan Mine Minnesota
  • Cryogenic Dark Matter Search (CDMS)
  • 46 scientist, 12 universities, Fermi lab

Activity
  • Because discovering dark matter takes up a lot
    of time and energy not to mention millions of
    dollars to support the project. Do you think that
    we should try and figure out what dark matter
    actually is or should be leave it because the
    universe if going to keep working the way it is
    right now anyway.
