Résumé |
In this talk, I will construct a definition of diff-invariant bulk observables
in lower-dimensional JT gravity, and argue for its uniqueness. I will use these
to construct bulk observer worldlines, their detectors and discuss the resulting
physical implications. For the case of observers falling into a quantum black
hole, I will discuss how quantum gravity effects lead to a violation of the
equivalence principle, but the absence of a firewall. Including wormholes into
the calculation causes the classical horizon to be operationally inaccessible
and the interior effectively sealed off from the outside. Based on 2607.03344
and 2609.05164. |
