Is this the “firewall hypothesis” of everything inside a black hole piling up in an infinitely hot infinitely thin surface just inside of the event horizon?

Yeah isn’t there something about how gravitational time dilation reaches infinity at the event horizon? Like going down to the black hole planet in “Interstellar” caused 20 years to elapse within minutes, because it was close to the event horizon.

Going down to the event horizon and coming back up would take an infinite amount of time, which no matter or information can possibly survive. So it does not matter what you do, you can’t get anything back.
