Jampolski and Rezzolla propose collapsing stars spawn tiny expanding universes
Technology
Physicists Daniel Jampolski and Luciano Rezzolla have come up with a wild new idea: when a huge star collapses, it might not always turn into a black hole. Instead, under the right conditions, it could spark the birth of a tiny expanding universe.
Their research just dropped in Physical Review D.
Dark energy could produce gravastars
The secret ingredient here is dark energy.
According to their calculations using Einstein's relativity equations, dark energy inside the collapsing star could push outward and stop it from becoming a black hole.
This would create something called a "gravastar," a compact object with no singularity or event horizon (the stuff that makes black holes so mysterious).
