Goethe Physicists Say Dying Stars Can Spawn Universes as Dark Energy, 68% of Cosmos, Halts Collapse

Summary
A new Physical Review D study argues some extremely massive stars may stop short of becoming black holes and instead create tiny nascent universes at their cores.
Daniel Jampolski and Luciano Rezzolla say dark energy provides the outward pressure needed to balance gravity, stabilizing a gravastar rather than allowing full collapse into a singularity.
The researchers link that gravastar core to Big Bang-like conditions, suggesting the emerging universe begins after the star has nearly reached the black-hole stage.
Dark energy is estimated to make up about 68% of the known universe’s energy-mass content, but the authors say their model explores an alternative outcome of collapse rather than disproving black holes.
With LIGO data still backing black holes, how can we ever prove gravastars exist?
If gravastars create new universes, could our own Big Bang have started inside one?
Gravastars vs. Black Holes: The 2026 Breakthrough Dynamic Model That Challenges the Fate of Collapsing Stars
Overview
In June 2026, researchers Daniel Jampolski and Luciano Rezzolla from Goethe University Frankfurt introduced the first dynamic model for gravastar formation, marking a major breakthrough in astrophysics. Their work provides a new theoretical pathway that challenges the traditional black hole paradigm, which struggles with issues like singularities and event horizons. Instead, their model suggests that when a massive star collapses, a core powered by dark energy can form, halting the collapse and avoiding a singularity. This alternative not only addresses long-standing questions about the fate of massive stars but also opens new directions for understanding the universe’s most extreme objects.
