Summary
Daniel Jampolski and Luciano Rezzolla say they have found the first dynamic solution to Einstein’s equations showing how a collapsing massive star could form a gravastar instead of a black hole.
Their model proposes that, at a very late stage of collapse, a tiny expanding universe emerges inside the star; dark-energy-like pressure then pushes outward strongly enough to halt further collapse.
That balance would leave an ultra-compact object with ordinary matter in its outer layers and a dark-energy-filled interior, avoiding both a singularity and an event horizon.
Published June 11 in Physical Review D, the work targets a roughly 25-year-old question over how gravastars could arise from ordinary matter, while the authors stress black holes remain the simplest standard outcome.
Have physicists finally found a way to erase the paradoxes of black holes from the cosmos?
Could gravitational waves soon reveal tiny universes hiding where we once thought black holes were?
If a collapsing star can birth a new universe, could our own universe exist inside another?
Dynamic Gravastar Formation Unveiled: Jampolski-Rezzolla Model Challenges Black Hole Paradigm (2026)
Overview
On June 18, 2026, physicist Daniel Jampolski and Professor Luciano Rezzolla announced the first dynamic model for gravastar formation, marking a major milestone in theoretical astrophysics. Building on Jampolski's master's thesis under Rezzolla's supervision, their model provides a concrete, dynamic solution to Einstein's equations and fills a long-standing gap in understanding these exotic objects. Gravastars, long considered intriguing alternatives to black holes, are ultra-compact stars without a singularity or event horizon. The new model explains how gravastars could actually form, moving the idea from theory to a plausible astrophysical phenomenon.
