About this episode

This episode discusses a new theoretical model suggesting that collapsing stars may form gravastars instead of traditional black holes.

A new theoretical model suggests that some collapsing stars may not form traditional black holes at all. Instead, they could become gravastars—exotic objects powered by an expanding interior that prevents complete gravitational collapse. If correct, this idea could offer a surprising alternative to singularities and reshape our understanding of some of the most extreme objects in the universe.
