These ones will be quite dim

Yeah, I suppose after a billion billion billion or so years, it probably would be

The light will eventually tire out and turn into radio waves or smth, I’m not a physicist

To al elder God that sees higher bands of the electromagnetic spectrum it would see be a very bright place!

Any self respecting elder god would be playing billiards with the black holes. Fire up the new big bang, ye tatterdemalion layabouts!

Is that because of the accretion disk?

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.

Black holes ain’t black because they didn’t vote for Biden
