If we could indeed watch something go into a ‘Black Hole’ from our direction, wouldn’t it get so close, then appear to just ‘freeze’ in place, because after getting so close we would no longer see any changes of the object?
I’m probably not explaining myself very well, but you may get what I’m saying. The whole concept is fascinating and difficult for me to wrap my often feeble mind around. lol
Astronaut B and the rest of us see a man instantly crushed at the Roche limit, his constituent atoms spread over the entire surface of the mass, perhaps with only a squeak of x-rays to indicate Astronaut A's thorough annihilation.
From Astronaut A's point of view, his acceleration toward the black hole would speed him up nearly to the velocity of light, and his perception would be of an "outside" universe coming to a halt, while he experienced an eternity of always being destroyed and always speeding toward an inevitable destruction that is always an eternity away.
Actually, he would die of starvation or old age before arriving at that end, but, still, this always kind of reminds me of traditional descriptions of literal hell, the burning dump of the universe. Eternal fire for those who don't escape, but a quick end for the "damned" for those who do escape.
Eternal damnation, as described by Christ (and reported by credible witnesses), is easier to imagine today than it was 100 years ago. We have at least one real example in nature, as common as dirt in the sky above.
