Stable, Thin Wall, Negative Mass Bubbles
in de Sitter Space-Time
Matthew C. Johnson, M. B. Paranjape, Antoine Savard,
and Natalia Tapia-Arellano
Abstract Up to now, only configurations of negative mass have been found (Belletête and Paranjape, Int J Mod Phys D22:1341017, 2013; Mbarek and Paranjape,
Phys Rev D90(10):101502, 2014), no stability or dynamics was considered. Here we
show the existence of stable, static, negative mass bubbles in de Sitter space-time.
The bubbles have an interior that is pure de Sitter, separated by a thin wall from the
exact, negative mass Schwarzschild-de Sitter space-time exterior. We use the Israel
junction conditions at the wall. We find the bubbles can collapse spherically to the
singular negative mass solution, violating the cosmic censorship hypothesis.
