A new theoretical study suggests that when a massive star collapses, it might not form a singularity hidden behind an event horizon, but rather the collapse could trigger the birth of a tiny new universe inside the dying star.

How this affects you

This study offers a novel theoretical alternative to the formation of black holes when massive stars collapse, proposing that such events could instead lead to the creation of gravastars containing new universes. This challenges existing understanding of stellar remnants and black hole physics, potentially reshaping future astrophysical research into the extreme conditions of stellar death.
