WebOct 6, 2014 · Black Hole Thermodynamics S. Carlip The discovery in the early 1970s that black holes radiate as black bodies has radically affected our understanding of general relativity, and offered us some early hints about the nature of quantum gravity. WebApr 22, 2024 · The EuclideanBTZ black holeis a hyperbolic 3-manifoldhomeomorphicto (the interiorof) the hyperbolic solid torus, hence to the knot complementof the unknotin the 3-sphere. (e.g Gukov 03, appendix A, Kraus 06, around Fig. 1, BKR 07, 2.1) Notice that the volumeof the hyperbolic solid torusis not finite.

The idea of a body so big that even light could not escape was briefly proposed by English astronomical pioneer and clergyman John Michell in a letter published in November 1784. Michell's simplistic calculations assumed such a body might have the same density as the Sun, and concluded that one would form when a star's diameter exceeds the Sun's by a factor of 500, and its surface escape v… WebApr 5, 2024 · We consider black hole solutions with electric and magnetic sources in the four-dimensional Einstein-Born-Infeld-AdS theory with spherical, planar and hyperbolic horizon geometries.

WebSep 5, 2024 · The foundation of thermodynamics is this equilibrium relation, which sets up the meaning of temperature. The zeroth law for black holes is that the surface gravity of a black hole, which measures the gravitational acceleration, is a constant on the horizon. So that assumes temperature being constant is the zeroth law. That’s not really right.
