    I know this is a joke, but i think the idea is that you would only look stretched to outside observers, but you yourself actually wouldnt perceive any stretching going on.

      I think you literally stretch; the part of you that touches the horizon line first experiences infinite gravity, while the parts of you outside the horizon line don’t, so you’re getting stretched out as the parts inside the horizon line fall in much faster

        No, that’s not the case at all.

        If you fall into a black hole, you can do no experiment to detect the horizon, it’s a completely unremarkable region of space to you.

        The stretching is just because of tidal forces, which means that gravity gets so much stronger closer to the black hole that your feet are pulled harder than your head, you experience the same thing standing on earth, it’s just that the change in gravity is basically negligible here.

      It is literally stretch because the difference in gravity at your feet would be much stronger than the gravity at your head, pulling you apart

      Depends on the size of the black hole.

      Really big ones can let you live for a surprisingly long time. (Not going to quote any numbers because I’m not completely sure of them any more)

      Bigger black holes become more and more gentle.

      The neat thing about black holes is the process would be both instantaneous and take literally eternity, depending on one’s perspective.
