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.

The black hole's a drain of ill-fame
That needs a less ominous name.
For better PR
it's gravastar.
Appearance improved - still sucks the same.
See also black hole.
