qroqqa commented on the word gravastar
A postulated alternative kind of structure to a standard black hole. Instead of a permeable event horizon it has a thin, dense shell of matter; instead of centring on a point singularity, the vacuum within the shell undergoes phase transition to a Bose-Einstein condensate.The name is 'gravastar' rather than the expected *'gravistar' to include the vacuum aspect.
