C. Prior to the discovery of Hawking physics were convinced – static gravitational field outside a black hole can not bear the particle. The alternating field is on the horizon in the hole "invisible", "intangible" to the outside observer, and it seemed to be forgotten. But quantum processes just as characterized by the fact that the particle can be where, in terms of classical physics, it does should not be. For example, the particle may "leak" through the energy barrier when she did not have enough energy to overcome it. S. Hawking has shown that this property of quantum particles in the case of black holes leads to a qualitatively new effect – the quantum evaporation of black holes to themselves, without external influences, they slowly disappear, transformed into thermal radiation, slowly tightened in space and time.
