A Self-consistent Model of the Black Hole Evaporation

Understand

We construct a self-consistent model which describes a black hole from formation to evaporation including the back reaction from the Hawking radiation.

• In the case where a null shell collapses, at the beginning the evaporation occurs, but it stops eventually, and a horizon and singularity appear.
• On the other hand, in the generic collapse process of a continuously distributed null matter, the black hole evaporates completely without forming a macroscopically large horizon nor singularity.
• We also find a stationary solution in the heat bath, which can be regarded as a normal thermodynamic object.
