General Relativity's Frame Dragging Confirmed

Earth's spin warps space around the planet, according to a new study that confirms a key prediction of Einstein's general theory of relativity. After 11 years of watching the movements of two Earth-orbiting satellites, researchers found each is dragged by about 6 feet (2 meters) every year because the very fabric of space is twisted by our whirling world. The results, announced today, are much more precise than preliminary findings published by the same group in the late 1990s.

I'm a veteran of two careers - high school math and physics teacher, retirement consulting actuary - who is now enjoying the pleasure of staying at home for my daughter. (My avatar is in honor of Will Durant, whom I consider the last true sage.)
