“A NASA probe orbiting Earth has confirmed two key predictions of Albert Einstein’s general theory of relativity, which describes how gravity causes masses to warp space-time around them. ”…
The experiment used four ultra-precise gyroscopes housed in a satellite to measure two aspects of Einstein’s theory about gravity. The first is the geodetic effect, or the warping of space and time around a gravitational body. The second is frame-dragging, which is the amount a spinning object pulls space and time with it as it rotates.”
