I've heard/read many times that in the general relativistic description of a black hole an object would pass through the event horizon unharmed (ignoring tidal forces) while quantum mechanics predicts that an object would be thermalised (firewall) and that this presents a paradox. I can't reference any particular papers here but I've watched a lot of Leonard Susskind's stuff on Youtube.

My understanding is that from the point of view of an observer falling into the black hole the field of view gets concentrated in a disk behind them due to the extreme lensing effects and tends towards infinite brightness and blue shift as they fall further towards the black hole.

Surely any object would be destroyed by high energy gamma rays before it reached the event horizon as observed from infinity.
