SUMMARY:Knowing So  Little about So Much\, Physics Department Colloqui
 um\, Hooman Davoudiasl \, Brookhaven National Laboratory
DESCRIPTION:The dominant forms of matter and energy in the Universe ar
 e of unknown 
\norigin.  In particular\, the presence of dark matter (
 DM) - constituting 
\nroughly a quarter of the cosmic energy budget - 
 has been established 
\nonly through its gravitational effects and its
  nature remains largely a 
\nmystery.  In this talk\, we will briefly 
 discuss some general aspects of 
\nDM theory and observation.  It is p
 ossible that DM belongs to a separate 
\nsector\, including various st
 ates and new forces.  We will discuss some 
\nof the ways that such a 
 sector may communicate with our visible world 
\nand reveal itself in 
 current and future experiments.
