Do unbounded bubbles ultimately become fenced inside a black hole?

TL;DR

This paper investigates the evolution of five-dimensional bubbles in flat spacetime, demonstrating through numerical analysis that initially expanding bubbles ultimately collapse into black holes.

Contribution

It introduces a numerical study of bubble dynamics in five-dimensional spacetimes, revealing their tendency to collapse into black holes.

Findings

Expanding bubbles eventually collapse into black holes.

Numerical methods effectively model bubble evolution.

Bubbles do not remain unbounded but are fenced inside black holes.

Abstract

We examine the dynamical behavior of recently introduced bubbles in asymptotically flat, five-dimensional spacetimes. Using numerical methods, we find that even bubbles that initially start expanding eventually collapse to a Schwarzschild-Tangherlini black hole.
