Read more at TechNewsWorld about the Einstein Gravity Effect Demonstrated by NASA.
According to Einstein's calculations, when a large, massive body such as the Earth rotates, it tends to pull the surrounding space around with it slightly, just as sticking a spoon in a jar of honey and twisting it will tend to drag around some of the honey.
The effect is extremely small -- amounting to about 6 feet (1.9 meters) in the distance that satellites, moving at about 18,000 miles per hour, cover in their orbits in a year -- but it is within the ability of NASA's tracking instruments to detect.
Paul and George meet to enjoy lunch in the Valley of the Sun and discuss whatever we feel like.

Einstein Right Again!
NASA's Gravity Probe B spacecraft in orbit around Earth has allowed astronomers to confirm a prediction made by Einstein's theory of General Relativity. They were able to directly measure an effect known as "frame-dragging."
