Okay. Here's hoping to hear from some of you theoretical physicists and cosmologists.
Particle-antiparticle pairs are popping into existence all the time, but the energy of the universe as a whole is conserved because they annihilate each other quickly. When this occurs near the event horizon of a black hole, one particle can be sucked into the black hole while the other escapes as Hawking radiation.
Now, I've heard several times that this is the reason why black holes will evaporate over time. But that doesn't make sense to me - the black hole isn't losing mass or energy in this transaction, it is gaining mass from the particle that's swallowed up. The Hawking radiation can't carry away any of the black hole's energy, because whatever it carries away ought to be exactly balanced by the particle that is swallowed.
I'm clearly misunderstanding something here. Any help for someone with a non-mathematical background?
