Einstein’s Theory Proven Right by Stanford-NASA Space Probe

A U.S. space probe carrying four gyroscopes has confirmed two key elements of Albert Einstein’s theory of relativity about 95 years after he postulated it and 56 years after he died.

Gravity Probe B, built by Lockheed Martin Corp. and designed by scientists from Stanford University near Palo Alto, California, measured how space and time are warped by gravitational bodies, a phenomenon called the geodetic effect. The probe launched in 2004 also analyzed frame-dragging, the way spinning objects pull space and time around them.
