Black Holes  

In General > s.a. censorship; history of relativistic physics; horizons; phenomenology; {#einstein}.
* Early idea: Calculation by clergyman John Michell in 1784 for situation in which the escape speed equals c (however, because of addition of velocities, in Newtonian theory light emitted by a moving source could escape).
* History: Schwarzschild solution found early, but before the work of Oppenheimer & Snyder, black holes were not thought of as real astrophysical objects; The term black hole was introduced by Wheeler, in a 29 dec 1967 -BK lecture.
$ Definition: A strongly asymptotically predictable spacetime M contains a black hole if M is not in J(), and M \ J() is the black hole region; In non-asymptotically flat spacetimes the notion seems to be physically less relevant, and many theorems would not hold.
* Remark: Classically a black hole can be thought of as a general relativity soliton, but not quantum mechanically, due to their radiation and instability.

Geometry and Topology > s.a. event horizons; models for topology change [censorship, genus].
* Hawking's theorem: If = 0, the constant time sections of the horizon of stationary black holes are topologically spheres.
* Black strings: Gregory & Laflamme argued that an instability along the extra dimension causes the Schwarzschild black string to break up into disjoint black holes; Horowitz and Maeda derived bounds on the rate at which the smallest sphere can pinch off.
