| Aug 20, 2011 at 8:41 | comment | added | Anixx | Actually this estimation is mostly inaccurate because the temperature will decrease as the body evaporates (due to decrease of surface acceleration), unlike a BH which evaporates at accelerating rate. Thus one should better estimate the "half-evaporation" time for Earth rather than the expected time of complete evaporation which is infinite. The figure in the question is just for illustration, it is calculated out of presumption that the rate of evaporation does not change. One can better think of it as of an approximate time of evaporation of Earth mass from Saturn. | |

| Jan 11, 2011 at 2:08 | comment | added | Zo the Relativist | I would warn you against extrapolating black hole temperature to estimating evaporation times. the back reaction problem (quantum effects create matter, which then perturbs the spacetime, which then change the quantum effects) in semi-classical gravity is extremely non-trivial, and once the star has radiated a large portion of its mass, the back-reaction effects will not be negligible. The premise of this problem, where the quantum radiation interacts with a matter distribution, is even more complicated. | |
