    I guess the next questions would be

    1. How fast? Really fast? Does this question even make sense?
    2. What does this say about the inside of the event horizon? Does it say anything? Is this black hole leaking real information?
    3. 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.

          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

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