When the 'evaporation' of a black hole supposedly occurs, it is always attributed to 'Hawking radiation.' As I understand it, Hawking radiation occurs when a virtual particle pair is 'split' at the exact edge of an event horizon. When this occurs, one of the particle pair escapes to 'normal' spacetime, while the other is pulled down into the hole. When this occurs, it is logical to assume that the black hole actually gains a very small amount of matter (the doomed companion of the free particle). As I understand 'evaporation,' it occurs when a portion of a 'thing' or condition actually yields part of its being or totality. With Hawking radiation, this is not actually happening, since the Black hole/singularity is not giving anything of its 'self' but is actually gaining (the sad particle of the pair). How can we speak of the black hole evaporating when in fact it is 'gaining' matter during Hawking radiation?
