A team of international scientists and university researchers assembled by the National Aeronautics and Space Administration (NASA) has found the first direct evidence that the Earth is dragging space and time around itself as it rotates, NASA said.
It said that the researchers believe they have measured the effect that was first predicted in 1918 by using Einstein's theory of general relativity by "precisely observing shifts in the orbits of two Earth-orbiting laser-ranging satellites."
The finding, said NASA, constitutes the "first accurate measurement of a bizarre effect that predicts a rotating mass will drag space around it."
The so-called "frame-dragging effect," said Erricos Pavlis of the Joint Center for Earth System Technology in Greenbelt, Maryland, one of the team leaders, "is like what happens if a bowling ball spins in a thick fluid such as molasses.
"As the ball spins, it pulls the molasses around itself," he said. "Anything stuck in the molasses will also move around the ball. Similarly, as the Earth rotates, it pulls space-time in its vicinity around itself. This will shift the orbits of satellites near Earth."
