> 11 Feb 2016 - LIGO, the Laser Interferometer Gravitational-Wave
> Observatory, has made the first direct detection of the gravitational
> radiation predicted by Einstein 100 years ago. Rainer Weiss was
> working on the technology for LIGO when I first came to MIT in 1976.
> The technical paper shows that a merger of two black holes of 36 and
> 29 solar masses occuring 410 Megaparsecs away leaving a 62 solar mass
> remnant, with 3 solar masses radiated away in gravitational waves.
> The peak strain was 10-21, and the last cycle of the signal was 7
> milliseconds long. The peak luminosity was equivalent to annihilating
> 200 solar masses per second. The signal was seen 14 Sep 2015 at
> 9:50:42 UTC by both Hanford and Livingston, with a 7 ms time
> difference pointing to a localization on the sky covering hundreds of
