Abstract: The dominant forms of matter and energy in the Universe are of unknown
origin. In particular, the presence of dark matter (DM) - constituting
roughly a quarter of the cosmic energy budget - has been established
only through its gravitational effects and its nature remains largely a
mystery. In this talk, we will briefly discuss some general aspects of
DM theory and observation. It is possible that DM belongs to a separate
sector, including various states and new forces. We will discuss some
of the ways that such a sector may communicate with our visible world
and reveal itself in current and future experiments.
