The thing that bothers me is that Hawking Radiation causes Black holes to
eventually evaporate (after about 10^67 years for one the mass of the sun,
more massive ones would take longer) but Black Holes contain an enormous
amount of entropy and the Second Law of Thermodynamics says entropy can't
decrease, so when a Black Hole disappears where did all that entropy go?
There are some ideas but nobody knows.
