A paper by Andrew J. S. Hamilton and Tyler McMaken (published in Phys. Rev. D 114, 024088, Aug 2026) argues that the black hole singularity is a 2-dimensional surface, not a point. Two free-falling observers on different angular trajectories lose causal contact well before reaching the singularity, and for rotating black holes the singular surface likely resides at the inner horizon where mass inflation instability drives collapse to a spacelike surface. The authors suggest quantum states of a black hole probably live on this 2D surface, coevolving unitarily with trapped Hawking radiation.
