Here's what I want to know...Whenever I see things about falling into a black hole, it's always said that an outside observer would never actually see the entity fall in...it would appear frozen right on the event horizon...So, why wouldn't this be the same, and we would just see the Neutron star hovering on the edge?
Or, is this about the idea that it is still there, and is just smeared across the accretion disk?
I think this is a great question. I find myself tempted to give an answer, based on the limited understanding that I have of this theory. But it's probably better not to try, and to just hope someone will give a helpful answer. Along with your query, I would add related questions:
For simplicity, assume we're talking about a very small entity, like the size of a single atom. Would the falling entity appear to red-shift as we watched it? As it approached the horizon, even if it were a very luminous object, would it appear to dim? Would its image appear to fade to darkness, simultaneous to it appearing to stop?
The PBS Space Time guy on YouTube (Matt O'Dowd) sure talks as if he has it all figured out, maybe we could ask him.
