Doing the (Gravity) Wave

My understanding of higher-order physics is very limited, but the news that the LIGO experiment has uncovered evidence of gravity waves emanating from two black holes is quite exciting.  I do wonder how often such an event will occur in order for the scientists to really use this to peer back into the first moments of the Big Bang, according to the ever-excitable Stephen Hawking.  On the other hand, if there truly are massive black holes at the centre of all galaxies, then it might not be such a rare event after all.  While this has made the news everywhere, this article goes a bit deeper into the mechanics of the experiment -- and has some droll comments BTL.

Congratulations to all, and particularly to Albert Einstein whose theories have been borne out (yet again).
