In February 2016, the Laser Interferometer Gravitational Wave Observatory (LIGO) announced discovery of the merger of two black holes, each of which weighed around 30 times the mass of the Sun. In addition to being the first detection of gravitational waves, it was also the first observational evidence of stellar mass black holes above 25 solar masses. Shortly thereafter, it was speculated that these black holes might make up the dark matter that has long been known to exist in galaxies (like our own Milky Way). Dr. Kamionkowski will discuss this possibility and explain why this hypothesis may or may not work.
