> and if black holes really do explode at the end of evaporation, then maybe that is also observable I suppose her reason to assume we can't observe this is that evaporation takes extremely long time. For example, a solar mass black hole will take about 10^64 years to evaporate [1] (this is approximately 7 * 10^54 times the age of the universe). Note that astronomical black holes are heavier than the Sun, so take even longer to evaporate. I suppose the micro black holes [2] might offer a glimmer of hope, but these objects are entirely hypothetical.
