Dark Matter: Evidence, Experiments, and Properties

The evolution of the Universe as a whole and the Milky Way within it is governed not by the normal matter humans know well (which takes the form of atoms and molecules) but some kind of unseen matter that must be very different. This lecture explores the empirical evidence that this dark matter exists and the experimental results that constrain its physical properties. While researchers know with great confidence that it is there, they don't see it directly; they don't know much about its fundamental nature. The lecture provides some ideas about how to learn more about the dark matter in the near future.
