John you scared me a bit with the 36/29, these being the masses of the first detected pair. If we had two pairs of the same masses, I would think we have some kind of problem with the instrument. No worries, we had about 2 solar masses go into gravitational energy.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Fun aside, the older ones among us may recall our misspent childhood when we first read about black holes.
