[time-nuts] LIGO detects gravitational waves

[Bill Beam]

The ring-down is due to the combined BH ringing down from oblate to spherical and rotateing while ringing.
The wave contains most of the lost mass/energy. There likely was also EM energy radiated from the surrounding
BH disks, but not observed here.
