A Role for the `Fauxrizon' in the Semiclassical Limit of a Fuzzball — •Mike D. Schneider — University of Illinois at Chicago, Chicago IL, USA

Recent remarks by Huggett and Matsubara (``Lost Horizon? - Modeling Black Holes in String Theory'', 2021) indicate that a `fauxrizon' (portmanteau of `faux horizon'), such as is relevant to understanding astrophysical black holes according to the fuzzball proposal within string theory (and perhaps in firewall proposals, more generally), might ultimately solve the familiar black hole evaporation paradox. I clarify, with general upshots for quantum gravity research, some of what this suggestion would amount to: namely, identification of intertheoretic constraints on global spacetime structure in semiclassical models of fuzzballs.
