Relativity prediction is correct

A key prediction of Albert Einstein's general theory of relativity has been confirmed by an experiment showing that the Earth's rotation drags the surrounding fabric of space-time along with it.
The phenomenon, known as frame-dragging, was one of the last untested predictions of general relativity. A NASA satellite, Gravity Probe B, was launched earlier this year to test the same effect.
"Frame-dragging is like what happens if a bowling ball spins in a thick fluid, such as molasses," said Errico C. Pavlis of the Joint Center for Earth System Technology, a leader of the international research team that measured the effect.
