True, but the hole under discussion here is not one of those. (And it's important to note that big holes have weak tidal forces at the event horizon. They still probably have pretty significant tides close to the singularity, but God only knows what actually goes on in there).
- libraryofbabel 4y ago> but the hole under discussion here is not one of those. That’s not correct: It’s a supermassive black hole at the center of a galaxy; the tidal forces will be weak at the event horizon.
- lisper 4y agoYeah, I know that's what the news reports say, but I'm pretty sure they got it wrong. A galactic hole doesn't emit radiation (except perhaps Hawking radiation) because its tidal forces are too weak.
