Following LIGO’s discovery of gravitational waves from the merger of a binary black hole, several colleagues and I speculated that these black holes could make up the dark matter long known to exist in galactic halos. I will explain why the idea, although nutty, was not completely crazy, and discuss several challenges the scenario has seen the past few years. I will also explain several interesting ideas and results in an array of areas of astrophysics that have followed from that initial work.
