ELI5: What does Hawkings discovery, black holes don't have event horizons, mean?
gpt
The basic paradox of the black hole event horizon is that all "information" - velocity and position of the particles going past it, etc. is 'lost' because it can never return past the boundary. So say a meteor heads right into the black hole - once it is torn apart crossing the boundary, we can't predict or say anything about the stuff that got sucked in.

A lot of stuff has been written about possible ways that this information may be retained, or is actually leaking out of the black hole, and things like that. One of these things is called Hawking radiation. Another is this 'soft hair' theory which seems to be what you're referring to.
