How long does it take until a quantum system
... Hawking’s results on evaporating black holes are only plausible as long as the semiclassical approach is valid. This seems to be not the case near the singularity, where a more fundamental modification of the classical theory due to quantum effects is expected to occur. If the semi-classical approxi ...
