The Strange Alternative to Black Holes Proposed by Physicists

Bedtime Astronomy

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.
