So we are at a distance from the black hole R>2GM/c^2 where quantum fluctuations happen all the time.
How is it possible that every time the anti-particle ends up in the black hole(the one that will decrease her mass) and eaven if it's so,how can the other particle escape?if they are at a really small distance with a huge potential energy,why doesent the anti-particle just attract with herslelf her partner with the Coulomb force?

The particle anti-particle picture for Hawking radiation is just one way to conceptualize this complex idea. It has its faults, because actually the particle that falls into the black hole must reduce the black hole mass, where real anti-particles have positive mass not negative mass.

Actually the result of Hawking radiation is a semi-classical result from analyzing quantum field theory in the curved space time Schwarzschild solution of general relativity. The details are actually pretty complicated.

Who knows what's actually happening.
Do you know any site with relativistic or non-relativistic formulas for the Hawking Radiation?
Or a PDF document of his paper?
Thank you for answearing.

ghost313, Hawking himself has said that the "particle pair" description of Hawking radiation is an analogy and is as close as he could come to an English language description of what is actually going on, which can only be described accurately by the math and is NOT really a particle pair event.
