Summary
Daniel Jampolski and Luciano Rezzolla said they have produced a first model for creating a static gravastar through the gravitational collapse of a spherical cloud of matter.
The model replaces a black hole’s singularity and event horizon with a de Sitter region—an expanding dark-energy-dominated interior that pushes outward as the surrounding matter collapses inward.
That inward-outward balance yields an equilibrium object the authors say could be made arbitrarily close in compactness to a black hole, making it hard for outside observers to distinguish.
The work is theoretical, but it offers a concrete formation pathway for a long-hypothesized black hole alternative that could even host a mini-universe inside.

Gravastars vs. Black Holes: The 2026 Dynamic Model and the Future of Stellar Collapse
Overview
In June 2026, Daniel Jampolski and Luciano Rezzolla achieved a major breakthrough in astrophysics by presenting the first dynamic and mathematically viable model for gravastar formation. Their research offers a compelling alternative to the traditional black hole theory, providing a new perspective on what happens to massive stars after they exhaust their nuclear fuel. Instead of collapsing into a singularity, the model shows that under certain conditions, a star can form a gravastar—a stable object where outward pressure from a core of dark energy balances gravity. This discovery opens new possibilities for understanding the fate of massive stars and challenges long-held beliefs about black holes.
