There was a youtube lecture I saw years ago that showed exactly what you'd see as you fell into a black hole and passed through the event horizon.

You'd see EVERYTHING that EVER crossed the event horizon. But critically, you'd see it EXACTLY as it was at the monent it crossed.

Sounds a bit crowded to me. Sounds a bit like I'd expect the big bang to look.

I thought you were supposed to get spaghettified and die instantly ?

  • At the event horizon of a large enough black hole, the tidal difference in gravity between your toes and head shouldn't be noticeable. There shouldn't actually be anything special about falling through the event horizon when looking at yourself.

    Outside though, you'd see everything start to blue-shift. Things below you would blue shift back to normal, and the universe above you would blue-shift and speed up until you'd see the heat death of the universe. Anything falling in after you would red-shift again as it approached to match your "normal" rate of time. Critically this would include any light or other particles, so it might be very hard to survive.

    No matter how fast you go or how weird the space time you are in, your local clock should still tick steadily to you, and you wouldn't notice anything weird.

      If you went in feet-first, you'd perhaps find it quite odd that your feet never seemed to cross the horizon, as they would have red-shifted so dramatically.

      > you wouldn't notice anything weird.

      Maybe you wouldn't notice that you never saw your feet cross, since you wouldn't have much time to ponder it before your head crossed as well, but at that point, you surely you would notice that everything below you is black, since all light (and everything else) is now destined for the singularity. That's the very definition of the event horizon. There wouldn't be any reflected light.
