abstract

  • The question of black hole evaporation is reviewed in the framework of quantum field
    theory in curved spacetimes and semiclassical gravity. We highlight the importance
    of taking backreaction effects into account to have a consistent picture of the fate of
    gravitational collapse in this framework. We describe the difficulties of solving the
    backreaction semiclassical equations due to practical complications of renormalizing
    the stress-energy tensor of quantum fields in general 3 + 1 spacetimes. We end with
    some personal views and plans on the subject.
