Executive Summary
- Gravastars are theoretical alternatives to black holes, possessing similar mass and density.
- Unlike black holes, gravastars are composed of dark energy surrounded by a thin shell of exotic matter.
- The shell of a gravastar is extremely cold, nearly absolute zero, and made of matter at the limit of physical possibility.
Event Overview
Gravastars are hypothetical astronomical objects proposed as alternatives to black holes. While sharing similar characteristics such as immense mass and density, gravastars differ significantly in composition and structure. Instead of a singularity enveloped by an event horizon, a gravastar consists of dark energy enclosed by an extremely thin shell of exotic matter. This shell is notable for being incredibly cold and dark, representing an extreme state of matter.
