  Does Dark Matter Exist?
  Host: Devlin
  Abstract: A range of dynamical properties of galaxies are difficult to explain in the context of dark matter models. I will review arguments in favor and against dark matter and discuss the possibility of a modified law of gravitation as an alternative. Cosmology will ultimately provide the testing ground for any proposed modifications to gravity. Current relevant cosmological observations and possible discrepancies will be discussed.
