This is great news for physicists! As I started to drive home from work today, I heard this on NPR. LIGO, the pair of mile-long L-shaped super-sensitive interferometers in Washington and Louisiana, picked up data last December looking a lot like a black hole collision. Everyone by now has heard the announcement last February, of a signal picked up last September, indicating black holes of masses of about 29 and 36 solar masses. Now there’s this collision, with masses about 8 and 14 solar masses.
Of course, it has been turned into audio. The version I heard on the radio sounded very much like something watery or airy being suddenly sucked up, or falling into a hole (of course.) The audio at https://www.ligo.caltech.edu/video/ligo20160211v2 uses the same data, but it doesn’t sound the same to me, but then, my car’s audio and my home computer’s audio aren’t the same.
