Answer to Question 1

The uncertainty principle allows for virtual particles to pop in and out of existence on extremely short timescales anywhere in space. The production of such particles near the event horizon of a black hole can result in one of the pair entering the black hole and the other remaining outside. Without its virtual partner, this particle becomes a real part of space (its mass is equivalent to the gravitational energy lost by its other half falling to the center of the black hole). By symmetry we expect equal numbers of matter and anti-matter particles to form around the black hole and these will eventually meet and annihilate each other, producing what is termed Hawking radiation. The creation of mass-energy from a quantum fluctuation comes at the expense of the black hole which (very slowly) evaporates.
