Gravastar Filled With Dark Energy Counters Stellar Collapse
The collapse of a star may result in a gravastar, an ultra-compact star resembling a black hole, rather than a singularity. Calculations using Einstein’s General Relativity suggest a new mini universe, filled with dark energy, could form inside the collapsing star and counterbalance gravity.
Physicists at Goethe University have proposed a surprising reversal of stellar collapse: the birth of a mini universe within a dying star. Their calculations, based on Albert Einstein’s General Theory of Relativity, suggest that instead of forming a black hole, a star might become a gravastar, an ultra-compact object stabilized by an expanding region of dark energy. This internal “Big Bang” would counteract gravity, preventing the formation of a singularity. How could…
