The way I understand it it, black holes decay because particle-antiparticle pairs appear so close to the black hole that the particle gets away, but the antiparticle falls in and annihilates part of the black hole (Hawking Radiation), but there are two things I don't understand:
1) When the antiparticle falls in, doesn't it add energy to the black hole (because energy is always positive) and shouldn't it increase the size?
2) Why would more antiparticles fall in than regular particles, since the eruption of pairs from the vacuum is random, shouldn't equal numbers of both fall in while equal numbers of particles and antiparticles escape as radiation? Wouldn't this mean that the black hole's size shouldn't change (or if my understanding of 1 was right, get bigger).
Any insight would be appreciated.
