What about annihilation? What happens to the quantum information in a particle and its antiparticle when they annihilate to give rise to a photon pair?
How is information conserved when one form of energy is converted to other?
Like how a black hole's gravitational energy is used to create photon pairs near the event horizon, what happens to the information in the gravitational wavepackets (gravitons?) and how is it not lost?
A black hole evaporates through hawking radiation, what I don't get is the requirement for an energy-negative energy pair production. Since it's the black hole's gravitational energy that's responsible for the pair production, even if one of them escapes, the black hole would lose energy anyway...
