The Marolf-Ori singularity inside fast spinning black holes

Abstract
The effective shock wave singularity at the outgoing leg of the inner horizon of a linearly perturbed fast spinning black hole is studied numerically for either scalar field, or vacuum, gravitational perturbations. We demonstrate the occurrence of the Marolf-Ori singularity, including changes of order unity in the scalar field $φ$ for the scalar field model, and in the Weyl scalars $ψ_0$ and $ψ_4$ (rescaled appropriately by the horizon function $Δ$) and the Kretschmann curvature scalar $K$ for the vacuum, gravitational perturbations model for both null and timelike geodesic observers. We quantify the shock sharpening effect and show that in all cases its rate agrees with expectations.
Yes, TFA says nothing about what happens after surviving the fall. But from Burko and Khanna (2019) I get this: > The fate of an astronaut who falls into a black hole depends not just on the latter’s properties (such as the intrinsic parameters, i.e., the mass and spin angular…
