Hawking radiation... more in depth?

Question

OK, i understand the two particles orriginate outside or at the event horizon and the negative particle gets sucked in and Annhialates (sp?) another positive particle inside creating a loss of mass. So the theory goes. But Wouldnt that creat The same mass in energy? And even if that was radiation energy why wouldnt the black hole keep it within its grasps? And even if I'm wrong is it called radiation for siplistic reasons.... because nothing is actually being radiated?

Answer 1

The annihiliation beyond the event horizon is not an annihilation in the standard matter-antimatter perspective. This would indeed violate conservation of energy. The virtual particle now inside the event horizon makes something real in there become its virtual pair, and they both disappear into the quantum fluctuations inside the hole.

Just like you don't have a constant stream of electron-anti-electron annihilation gamma rays from the seething ocean of virtual particle pairs we live in, you don't get gamma rays from the pair inside the black hole.
