[time-nuts] LIGO detects gravitational waves

[Nick Sayer]

I watched the video. It’s a spectacular discovery, no doubt. But the next day, the headlines in the non-technical press were all about how we can now “hear” the universe. The parlor trick the scientists did for the press conference was what lead the news. I don’t know which side the face-palm should be on.
