Quantum tunnelling and black holes

  1. Nov 13, 2012 #1
    Just a quick question, that I'm not completely clear about;

    Quantum tunnelling allows particles to overcome barriers that they classically shouldn't be able to overcome, my question is simply, do/can particles escape a black hole after passing the event horizon due to tunnelling? If not, why?

    Thanks :)

    There's a huge difference between the two.

    In ordinary tunneling, the particle only has to overcome a potential barrier, while the "frame" that it is in (space-time) is not affected, i.e. the spacetime didn't curl up onto itself.

    This is not the case beyond such event horizon. This is not simply your "potential barrier" to deal with, but rather a completely complex and new/unknown physics.

    Thankyou! Makes sense, a bit of a silly question really..
