Towards a spacelike characterization of the null singularity inside a black hole

Year: 2025

Type: article

Abstract: We propose a method for recognizing null singularities in a computer simulation that uses a foliation by spacelike surfaces. The method involves harmonic time slicing as well as rescaled tetrad variables. As a ‘proof of concept’ we show that the method works in Reissner–Nordstrom spacetime.
