I was thinking about Hawking Radiation and the idea that black holes evaporate by bleeding off energy as separated virtual particle pairs along the event horizon but was wondering whether or not people are certain this follows regular thermodynamic laws.
If a particle pair arises along the event horizon and one particle escapes the black hole, yes that would seem to produce Hawking Radiation but wouldn't the other particle be trapped in the black hole and fall inside as well? There seems to be one event that violated thermodynamics - the Big Bang.
I assume we've never observed a black hole evaporate yet and assume along this same line we can't be certain they follow normal thermodynamics (they're far from normal objets). It seems we're going to be making them on Earth.
So anyway, how does having additional virtual particles falling into a black hole lead to it evaporating? It seems this would simply add more vacuum energies to it. What am I missing?
(Is it that virtual particles don't truly exist so effectively matter from the black holes is leaking out whenever a real particle in the virtual pair escapes? That could make some sense but it would seem to require a view of black holes different than the typical model of everything compressed to a central point)
