The Most Precisely Tested Theory in the History of Science

NASA held a big press conference yesterday to announce that the Gravity Probe B experiment had confirmed a prediction of General Relativity that spacetime near Earth should be “twisted” by the Earth’s rotation. A lot of the coverage has focused on the troubled history of the mission (as did the press conference, apparently), but scientifically… Continue reading The Most Precisely Tested Theory in the History of Science
