Ha, who am I kidding. It turns out they may be responsible for ending star formation across the entire universe.

They were discovered as the driving force behind quasars, where matter is heated to extreme incandescence before its plunge into vast black holes. But if that weren’t enough, we soon realized that every single decent-sized galaxy contains such a supermassive black hole. By the beginning of the 21st century it became clear that black holes and the galaxies that contain them are very closely connected. The bigger the galaxy, the bigger its supermassive black hole. That might not sound surprising. What was weird was how closely they were connected. There’s a tight correlation between the mass the central black hole and the mass of the stars in the galactic bulge – that’s the central ball-like part of a spiral galax
