Similar hypotheses have been considered. The most popular (edit: AFAICT, but I'm not any kind of scientist), gravastars, would appear to have been ruled out by LIGO, as described here https://astronomy.stackexchange.com/questions/25449/gravasta... in the article linked therein. And as my current sibling comment mentions, they're not much good for dark matter either. They would be exactly as good as black holes for dark matter and, since they are still compact enough to do gravitational lensing, are ruled out by the same test |
