Daniel Jampolski and Luciano Rezzolla from Goethe University Frankfurt have found a mathematical route showing how a collapsing star might form a gravastar, avoiding a black hole’s singularity and event horizon.

How this affects you

This theoretical model provides physicists with a concrete framework to test whether black hole alternatives can arise from ordinary gravitational collapse, potentially sharpening efforts to distinguish black holes from gravastars through future observations. It expands the understanding of extreme gravity's effects on stellar collapse.
