80% of the matter in the universe is "dark matter", a neutral, diffuse, and weakly-interacting material made of an unknown elementary particle. In this colloquium, Michael Peskin will explain how we know this, and how we might try to directly observe dark matter particles in the galaxy.  He will then examine dark matter from a particle physicist's viewpoint and explain how we will use data from high-energy particle colliders to discover and identify the dark matter particle.
