I was watching a video about how an observer outside a black hole would watch someone slow to a halt at the event horizon and I don't question it, as that makes sense.
My first question to the Astrophysicists out there is what the observer falling into the black hole would see. It would make sense to me that they would observe the rest of the universe progress through the entirety of its existence.
Does this make sense?
My second question is about what people say would happen for a supermassive black hole, that it would be pleasant when crossing the event horizon. If the event horizon means that no world lines can travel away from the black hole, doesn't that imply that, once crossed, a person could no longer think, as impulses in the brain travel slower than light and cannot travel from place to place, but only towards the center of the black hole? Would this also apply when getting close to the black hole (i.e. within a few kilometers of the black hole's event horizon)?
Thanks for your time!
