Numerical simulations of generic singuarities

TL;DR

This paper presents numerical simulations of vacuum spacetimes approaching singularities, revealing that the singularity is spacelike with local, oscillatory dynamics as it is approached.

Contribution

It provides the first detailed numerical analysis of generic, symmetry-free vacuum singularities, demonstrating their spacelike and oscillatory nature.

Findings

Singularities are spacelike in the studied spacetimes.

Approaching the singularity, the dynamics become local.

The behavior near the singularity is oscillatory.

Abstract

Numerical simulations of the approach to the singularity in vacuum spacetimes are presented here. The spacetimes examined have no symmetries and can be regarded as representing the general behavior of singularities. It is found that the singularity is spacelike and that as it is approached, the spacetime dynamics becomes local and oscillatory.
