Confidence 5.1 sigma, ringdown to a Kerr black hole seen, too
Update: On Monday, 2 pm DC time, LIGO at Twitter has officially announced the press conference on Thursday. An hour later, the LIGO website posted an announcement, too. VIRGO in Italy organizes an event at the same moment, 16:30 Italian time. CERN should do a webcast, too. But please bookmark this YouTube page where the webcast will start on Thursday.
For those of us who "knew" that there would be an announcement of a LIGO discovery (timed to coincide with the publication of their paper in Nature) involving a black hole merger, was there a reason to watch the Thursday February 11th 10:30 am press conference in D.C. (National Press Club)? You bet. As recently as 10 hours ago, we still didn't know some numbers and details that were going to thrill us despite the previous knowledge.
