Just a stupid question from a non-physicist. The only theoretical mechanism I know of for ejection of mass from a black hole is Hawking radiation, which I understand to be due to quantum effects near the event horizon, and of extremely small magnitude (9*10^-28 watts for an idealized black hole of 1 solar mass). How then does a black hole collision resurrect 3 solar masses of energy from beyond the grave that is the event horizon?

30-solar mass black hole coalesces with a 35-solar mass black hole, producing a 62-solar mass hole, giving out 2-3 solar masses worth of gravitational wave energy in approx. 1/5 second !
76-minute video of the talk Rainer Weiss from MIT recently gave at KITP.
It was an excellent talk that explains much about their detection of gravity waves.
