Main Question or Discussion Point
As I understand it, the crux of the issue is: how is information preserved across the event horizon, in this case, the arrangements of subatomic particles, atoms, etc right on up through the individual parts, etc., of the creature in question. That, and the relativistic escape velocity required to be overcome. What I have in mind is a creature in a very far distant future made up of nano-modules which, after having been banished into a galactic supermassive black hole, slowly crawls out, bit by bit, over billions of years. Plausible?
