The Evaporation Of Black Holes

I found it extremely interesting that black holes could evaporate. All because of quantum mechanics. Vaccuum fluctuations outside the event horizon can be turned into real particles by the tidal forces of the black holes gravity. Doing this requires the expenditure of energy, and when these particles escape the gravitational pull of the black hole and "fly off" into the universe, that is energy that the black hole no longer has. That'sroughly how it works. Any comments?
