Webb26 mars 2016 · A black hole’s entropy is proportional to the surface area of the black hole (the area of the event horizon), unlike conventional systems where entropy is proportional to volume. This was Bekenstein’s discovery. If you put more matter into a black hole, it cools down. As a black hole emits Hawking radiation, the energy comes from the black ... WebbWhen one talks about the surface gravity of a black hole, one is defining a notion that behaves analogously to the Newtonian surface gravity, but is not the same thing. In fact, the surface gravity of a general black hole is not well defined. However, one can define the surface gravity for a black hole whose event horizon is a Killing horizon.
