Anyway it's great that we have further confirmation, if any were needed, that Einstein's 100-year-old theory of the universe is correct. I don't think this is quite as surprising or momentous as a lot of news reports make out... we've had a long time now to confirm this theory in all its aspects, and have found zero counter-examples. It would have been surprising if the absence of gravitational waves had been proved, but of course it is hard to prove a negative.
Well anyway it was fun, and the diagrams are cool. Onward!
