An Alternative to Black Holes: Gravastars with Big Bangs Inside

The problem with stellar mass black holes is that general relativity can't account for their strangeness. But the theoretical gravastars, an alternative to black holes, don't clash with general relativity in the same way. Nobody has figured out how they could form through Einstein's equations, until now.

Stellar mass black holes may not be black holes at all. Instead, they could be a type of extremely compact star called a gravastar, which mimics a black hole. This is according to theoretical phsyicists who have discovered a solution to Einstein's Theory of General Relativity that doesn't automatically result in a black hole when a star collapses at the end of its life.
