Another

viewpoint of this is that the

antiparticle created can be viewed as the normal

particle, but traveling backward in

time. In this view, the particle escapes from the

black hole, traveling backward in time, and then scatters, and reverting to normal timeflow.

Yet another view is that a particle can

quantum tunnel out of a black hole. The chances of this happening increase as the black hole shrinks (shorter distance to tunnel) and thus a small black hole emits more radiation than a large one. The energy output increases greatly as the black hole gets miniscule, ending in a explosion of sorts as the hole evaporates completely, having lost all of its

mass/

energy in radiation.

The hawking radiation corresponds exactly to perfectly normal

thermal radiation from a

blackbody object, and can be used to calculate the 'surface temperature' of the black hole.
