This is not a duplicate. I am not asking whether anything can escape a BH, I understand nothing can. My question is whether the potential barrier in the definition of Quantum tunneling can be a BH EH? Does the EH qualify as a potential barrier?
I have read this question:
But there is no answer.
Now the answers mention Hawking radiation. Not the type where particle-antiparticle gets created, one inside the EH, one outside. I am talking about the Hawking radiation where it is about Quantum tunneling.
Yet, I read everywhere on this site that nothing can escape the BH.
Please see here:
Quantum tunnelling or tunneling (see spelling differences) is the quantum mechanical phenomenon where a subatomic particle passes through a potential barrier. Quantum tunneling is not predicted by the laws of classical mechanics where surmounting a potential barrier requires enough potential energy.
Now the trick here is, that even though the EH would be a potential barrier, still, nothing can tunnel through it from inside, because nothing can move outwards from inside. Am I correct? Is the EH a potential barrier? Is it just that the direction of the particles can never be outwards?
Can this potential barrier be the EH of a BH?
If not, why is the EH different then a potential barrier in the definition of Quantum tunneling?
