Physicists and engineers from Stanford University and NASA have collaborated to create an experiment to test two extraordinary, unverified predictions of Albert Einstein’s general theory of relativity. The Gravity Probe B experiment uses four gyroscopes orbiting over the Earth’s poles. The site offers a general interest section with educational material, FAQs and an image library. Along with weekly highlights, a technical interest section supplies information on scientific papers, contacts, an orbit timeline and link to the ground station. Go to: einstein.stanford.edu/
