Black holes feed on all matter and energy, so of course any dark matter that enters the event horizon is included. Of course consumed mass (energy) counters the evaporation, any energy going in, obviously counters the hawking evaporation (energy going out). read more

Dark matter may have turned spinning stars into black holes near the center of our galaxy, researchers say. There, scientists expected to see plenty of the dense, rotating stars called pulsars, which are fairly common throughout the Milky Way. read more
