A team of astronomers led by Ignazio Ciufolini from the Wuhan Institute of Physics and Mathematics in China has reported the most accurate measurement of the terrestrial Lense-Thirring effect, which is a phenomenon predicted by Albert Einstein’s general theory of relativity. This effect describes how a rotating mass, such as the Earth, influences the fabric of space and time. The team's measurement reduces the uncertainty of this effect from several percentage points to 0.2 percent, achieved using a satellite designed to resemble a golf ball and a disco ball.
