Black Holes

Regions of space where gravity is so strong that nothing, not even light, can escape, including the supermassive black hole at the centre of the Milky Way and stellar-mass black holes found in X-ray binaries. An object belongs here when its cited article calls it a black hole. Members are placed here from their own cited Wikipedia articles, each with a verbatim supporting quotation, so a reader can check why an entry sits in this group. The grouping forms part of the browse path for this section of the atlas.
