Description
The fundamental scale of gravity could be significantly lower than the Planck scale due to the existence of a large number of particle species. This would also mean that processes exceeding this energy scale could produce black holes. In this talk, I will discuss two consequences of such a situation: first, the production of micro black holes in the corona of active galactic nuclei, together with their accompanying phenomenology; and second, their prolonged lifetime due to the memory burden effect. In some regions of the parameter space, their lifetime exceeds the age of the universe, which opens the possibility that primordial versions of such black holes could be viable dark matter candidates.
