Hawking’s seminal result, that black holes behave as black bodies with a non-vanishing temperature, suggests that black holes should evaporate. However, Hawking’s derivation is incomplete as it neglects the backreaction between radiation and geometry. Including it requires to incorporate quantum gravity. This talk focuses on the description of the conceptual challenges associated with black hole evaporation and sketches a recent proposal designed for meeting them. The intention is to eventually derive quantum gravity triggered deviations from Hawking’s evaporation formula and to convert them into measurable data.
