In this informal talk, I shall discuss a proposal that "Dark" Matter
consists of antimatter (strange) quark nuggets, naturally explaining
both baryogenesis and the similar amounts of visible and dark matter.
But how can antimatter be "dark"? Don't observations rule out this
proposal? On the contrary, not only is our proposal consistent with all
known constraints, but it provides a common resolution for three sets of
puzzling diffuse emissions from the core of our galaxy: the 511 keV
emission observed by INTEGRAL, a diffuse x-ray emission observed by
Chandra, the microwave WMAP-haze, and an excess emission below 30 MeV.
I will explain the basic ideas behind this proposal and hope to
stimulate a discussion leading to further ways of testing or ruling out
