Main Question or Discussion Point
I hear that black holes evaporate, but does it all get converted into Hawkins radiation? And what role do white holes play in evaporation?
Hawking.I hear that black holes evaporate, but does it all get converted into Hawkins radiation?
There are no indications that white holes exist.And what role do white holes play in evaporation?
Yes, smaller black holes radiate at higher temperatures. The Hawking temperature is directly proportional to the surface gravity, [itex]\kappa[/itex], of the object, [itex]T = \kappa/2\pi[/itex]. As the black hole shrinks, its surface gravity goes up (proportional to [itex]1/R^2_S[/itex], where [itex]R_S[/itex] the Schwarzschild radius) and, hence, so does its temperature.Thanks, and is it true that the smaller the black hole, the faster it evaporates? And is there a critical mass that prevents super massive black holes from evaporating?
