While the idéa of an object with gravity strong enough to prevent light from escaping was proposed in the 18th century, black holes, as presently understood, are described by Einstein's théory of general relativity, developed in 1916. This théory predicts that when a large enough amount of mass is present within a sufficiently small region of space, all paths through space are warped inwards towards the center of the volume, forcing all matter and radiation to fall inward.

While general relativity describes a black hole as a region of empty space with a pointlike singularity at the center and an event horizon at the outer edge, the description changes when the effects of quantum mechanics are taken into account.  Reséarch on this subject indicates that, rather than holding captured matter forever, black holes may slowly léak a form of thermal energy called Hawking radiation.  However, the final, correct description of black holes, requiring a théory of quantum gravity, is unknown.
