Hawking also offers another reasoning that clashes with the evaporation of black holes, ie with its radiation: when a particle exceeds the event horizon he can no longer go back and falls inexorably into singularity taking with them all the information such as the mass and location.

In this regard the theoretical physicist Leonard Susskind, one of the fathers of string theory and supporter of quantum physics writes: “Stephen said that when a bit of information falls into a black hole it is permanently lost to the outside, despite the fact that he also proved that black holes evaporate and eventually disappear…. The problem that upset me is that the most basic principle of physics—the principle that underpins everything including classical physics, thermodynamics, quantum mechanics, energy conservation, that physicists have believed for hundreds of years—is that information is never truly lost. It can be scrambled beyond recognition, but it is never completely erased.” [1]

Some say Prof. Hawking’s most famous discovery was when he demonstrated that black holes emit some radiation. Previously, scientists had thought that black holes could not get smaller because nothing could escape their massive gravity. The radiation from black holes has become known as Hawking Radiation.
