Description
Quantum Gravity induced corrections at the classical level are usually too small to be relevant for phenomena that can be probed by current observations. In this talk, I will focus on spherically symmetric solutions of Quadratic Gravity. I will discuss a mechanism that ensures that even if corrections to the Schwarzschild solution from General Relativity are small, they become dominant just outside the would-be event horizon - even if the corrections are Planck-sized to begin with. Confronting the Quadratic Gravity solutions, that are all sensitive for this mechanism, with observations from the Event Horizon Telescope allows to rule out a considerable portion of the phase space.
