#403 – Lisa Randall: Dark Matter, Theoretical Physics, and Extinction Events
Lisa Randall
And the interesting thing is that if some of the dark matter does radiate, and I like to call it dark light because it's light that we don't see but dark matter would see, it could radiate that and then it could perhaps collapse into a disk the same way ordinary matter collapsed into the Milky Way disk. So it's not all the dark matter, it's a fraction.
