The evolution of conifolds

TL;DR

This paper simulates the gravitational collapse of conifold geometries, revealing horizon formation and proposing a candidate black-hole solution as the end state of the collapse.

Contribution

It provides the first detailed simulation of conifold collapse dynamics and identifies a potential black-hole final state.

Findings

Horizon forms during conifold collapse

Black-hole structure is characterized post-collapse

Collapse leads to a stable black-hole candidate

Abstract

We simulate the gravitational dynamics of the conifold geometries (resolved and deformed) involved in the description of certain compact spacetimes. As the cycles of the conifold collapse towards a singular geometry we find that a horizon develops, shielding the external spacetime from the curvature singularity of the newly formed black hole. The structure of the black hole is examined for a range of initial conditions, and we find a candidate black-hole solution for the final state of the collapse.
