I guess the next questions would be

How fast? Really fast? Does this question even make sense?
What does this say about the inside of the event horizon? Does it say anything? Is this black hole leaking real information?
Is black hole spin quantized like quantum spin? Is it spin-up or spin-down?

Quantum Physics “spin” has nothing to do with actual spinning. It’s just a weirdly named property of particles.

I've always thought that they should have just named the properties something like P1, P2, etc. So there's no connotation.

Spin is a form of angular momentum, so there is a reason for the name. It’d be a pain in the butt to learn if properties didn’t have catchy names too.

I thought "spinning" was meant rather literally in this case and not in some quantum sense

[-] anlumo@lemmy.world 1 points 11 months ago

For black holes, it does refer to actual spinning. Particles are the ones not really spinning.
