These mfers are like glitches in reality. Even trying to wrap my head around wtf they are freaks me out. How the hell can there be a thing in this universe that has infinite density? That doesn't even make sense.

Ugh

    I'm not exactly sure how black hole evaporation works into this

    Yeah I thought I was with you but then this doesn't make sense at all. If black holes can cease to exist then surely anything that was "frozen" at the event horizon should just get flung off into space

      Hawking Radiation, I believe is the term for however something, uh... I guess escapes the black hole.

        So, what, a black hole is like a cosmic grinder that just converts all that matter into hawking radiation ("instantly" from the perspective of the thing being destroyed) and nothing ever actually reaches the singularity?

          Ask three physicists this question and you will get three completely different answers to it. This question is one of the biggest unresolved questions in physics.

          It seems like maybe they do, but if so, then they're able to reduce matter from a complex state to a simple one, meaning they can reduce entropy in a closed system, which isn't supposed to be possible.

        From my understanding, pairs of particles pop into existence everywhere in the universe, all the time. These particles have a negative and a positive charge, and they cancel each other out moments after popping into existence. However, these pairs of particles can pop into existence in a way that causes one of them to appear inside the event horizon of a black hole, while the other pops into existence outside of the event horizon. Over time, this ??? and the black hole evaporates.

          The particle-antiparticle pair thing is an imperfect analogy. PBS explains it well here https://youtu.be/qPKj0YnKANw

      It might be related to the black hole information paradox, idk
