According the Special Relativity, all objects contract their length if moving fast.
As the observer falls into black hole, his relative speed to it increases up to the speed of light. But from his point of view, it is the Black Hole moving, not himself.
As such, the thickness of the Black Hole in the direction of the falling observer should contract.
At the moment of the impact on the event horizon, the speed of the observer will be equal to the speed of light, so the black hole should appear flat. Moreover, the point of impact on the event horizon would councide with the center of the black hole, e.g. singularity. As such, it seems the observer has no time to travel towards singularity after moving past the event horizon, but rather he will hit the horizon and singularity at the same time.
Also, the fact that the black hole shrinks may lead to the blueshift in the apparent Hawking radiation as its wavelength is proportional to the Black Hole dimentions. If this is true, the observer should experience very strong blue-shifted radiation due to dynamic Casimir effect, which may correspond to the firewall idea.
Is my picture correct?
