Abstract

For nearly a century, we have known that the majority of matter in the universe is not luminous. In the past few decades we have come to be certain that this matter is not only not luminous but not made out of any of the particle ever observed in a laboratory. I will describe the ongoing hunt for this matter and the prospects for the discovery in the next decade. I will further discuss recent claims the dark matter may have been discovered in various signals, and prospects for resolving these claims in the next few years. Finally I will touch on the idea of "dark forces," the idea of an expansive dark sector that is much greater than a single dark particle.
