"Excited rumors began circulating on Twitter this morning that a major experiment designed to hunt for gravitational waves—ripples in the fabric of spacetime first predicted by Albert Einstein—has observed them directly for the very first time. If confirmed, this would be one of the most significant physics discoveries of the last century."

[Alan Weinstein, who heads the LIGO group at Caltech, had this to say via email: “My response to you is no more or less than the official one, which is the truth: ‘We are analyzing 01 data and will share news when ready.’ I’d say that it is wisest to just be patient.”]
