Physicists Propose Mini-Universe Gravastar Halting Black-Hole Collapse

6/16/2026

Summary

Story summary

Theoretical physicist Daniel Jampolski and Professor Luciano Rezzolla presented a dynamic solution to Einstein’s equations showing a collapsing massive star can generate a miniature universe.
The mini-universe pushes outward against gravity, halting collapse before a black hole forms.
This balance yields a stable gravastar rather than a singularity-containing black hole.
Published in Physical Review D, the findings answer a 25-year-old question while noting they do not reject black holes.
