And Hawking radiation. Hawking radiation is pretty "dark" for solar-mass scale black holes and up, but it can become relatively very intense for smaller holes.
For the holes we observe astronomically, the things we can see are the accretion disks and the orbits of stars around the black hole.
But that happens because of matter falling into them, right? When they've already swallowed everything, there's not going to be accretion disks.
Yeah, though eventually they should all evaporate one after another with a last huge tiny energy burst due to hawking radiation. But that will take a looooooooong ass time. And we still don't know (might never know) if hawking radiation is real.
They said the same thing about the curvature of spacetime 100 years ago. Then it was proven like three years later.
