The nature of dark matter has long been questioned, but the recent discovery of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO) has renewed interest in the possibility that dark matter could actually consist of primordial black holes in the mass range of 10 to 1000 solar masses. Could dark matter be made of these intermediate-mass black holes that formed at the beginning of the Universe? A recent study takes a new look at this question and concludes... Probably not.
