We argue that, instead, what these results imply is that the inner horizon remains non-singular when leading-order backreaction of the quantum fields is computed, but, after next-order backreaction is accounted for, it will become singular. Then, strong cosmic censorship will be enforced in the BTZ black hole. We support our claims using a four-dimensional holographic dual of the system, which connects the instability of the inner horizon of the BTZ black hole to that of Kerr-type black holes.9 p.application/pdfengcc-by (c) Emparan García de Salazar, Roberto A. et al., 2020https://creativecommons.org/licenses/by/4.0/Espai i tempsForats negres (Astronomia)GravitacióSpace and timeBlack holes (Astronomy)Gravitationinfo:eu-repo/semantics/article7020072021-07-06info:eu-repo/semantics/openAccess
