I've read as much on the subject as I can before getting into the actual math of it, so I need people who know the subject better then I do to answer my question.
The way I understand it, at the quantum level, particle/anti-particle pairs are created all the time and annihilate before they can impact the universe with their presence.
The way hawking Radiation works as I understand it, a pair is created on the edge of the event horizon, and as the pair is created, and before it can annihilate, the anti-particle falls into the black hole, and the positive particle is seen by the rest of the universe as if the black hole had just expelled matter.
Now, given how the uncertainty principle will never allow for any particle to have a known position, how can the black hole only absorb the anti-particle? Why isn't the black hole sometime getting the positive particle and therefore gaining weight? While the universe gets the bad end of the deal and gets an anti-particle?
So in summary, shouldn't by sheer luck a black hole remain stable in regards to hawking radiation? Or is there some artifact of physics, or something similar to the CP violation going on?
If its CP violation, I would imagine that the discrepency would be immensely small given the original scale for the universe, so that explanation seems somewhat weak.
Finally, as far as I understood it, negative particle retains their mass, as far as physics is concerned, there are no particle with negative mass, so what exactly happens for a particle from a pair creation from quantum fluctuation to emit a particle that is absorbed by the black hole to count as lowering its mass?
I mean, ok, so the universe sees a particle that seems to have been emited by the black hole, however, since the black hole itself absorbed something, and as far as I know mass is invariant to the actual polarity of a particle, how does the black hole loses mass?
Is this a new quantum mechanic property I've never read? Redistribution of mass to satisfy math?
I remains puzzled by how the black hole should lose mass because it so happened to gobble up a particle that was too close to its event horizon.
The way I see it, I'm also not sure how a particle created so close to the horizon would have the energy to get away from it?
I can imagine the theory says that the black hole imparts some energy to the particle to escape, but how would such a mechanism work? And why wouldn't it work for normal matter?
That would mean black hole can arbitrarely eject matter from its event horizon thus losing mass? Do we know of any such mechanism?
Anyway, looking forward to some ideas or explanation regarding that one.
