The Supermassive Black Hole in RGG118

Scientists have identified black holes in an approximate like 100 to 200 galaxies. That includes really large galaxies, like Andromeda, and also dwarf galaxies. There's something else going on here that makes us suspect that maybe every single galaxy has a black hole in it. We notice this very close connection between the mass of the supermassive black hole and the mass ofthe galaxy.
