Colliding branes and big crunches

TL;DR

This paper investigates the collision of domain walls in Anti-de Sitter spacetime, concluding that such collisions lead to big-crunch singularities instead of black branes, providing insights into spacetime singularity formation.

Contribution

It offers a novel analysis of colliding branes in AdS space, clarifying the nature of resulting singularities as big crunches rather than black branes.

Findings

Collisions produce big-crunch singularities.

Singularities differ from black brane formations.

Global structure of spacetime is characterized by these singularities.

Abstract

We examine the global structure of colliding domain walls in AdS spacetime and come to the conclusion that singularities forming from such collisions are of the big-crunch type rather than that of a black brane.
