It's hard to know which stars in the sky will turn into black holes. And which ones will open up worm holes into entire new universes.

A black hole is simply the end of space as we know it!

There are no black holes in the sense of regimes from which light can't escape to infinity.

Evolutionary cosmology formulates theories in which a universe is capable of giving rise to and generating future universes out of itself, within black holes or whatever.

Black holes can bang against space-time as mallets on a drum and have a very characteristic song.

Things changed with the discovery of neutron stars and black holes - objects with gravitational fields so intense that dramatic space and time-warping effects occur.
