Etymology

Blend of gravitational + vacuum + star, first hypothesized in 2001.

Meanings

1. A proposed alternative to black holes that is more consistent with quantum mechanics.
   • These dark objects do not have an event horizon, and there is no singularity at their center, as is the case with classical black hole solutions in general relativity. In the gravastar, the quantum physics of the baryonic matter at the shell or crust surrounding the interior vacuum prevents the formation of a general relativity event horizon. 2020, John W.
