Spinning massive objects drag spacetime along with them. This curious phenomenon is an important prediction in general relativity, which has been confirmed from a variety of celestial bodies and ...

A groundbreaking study published in Science Advances has confirmed one of Albert Einstein’s predictions from over a century ago: spacetime vortices, also known as frame-dragging, have been directly ...

A violent stellar disruption recorded in 2024 has given astronomers their most comprehensive evidence yet of a black hole twisting the very fabric of spacetime around itself. This effect is known as ...

A satellite designed to test one of the more twisted predictions of Albert Einstein’s general theory of relativity is finally at its launch site after 40 years of preparation. The probe will look for ...

According to a prediction of general relativity, the spinning mass of the Earth affects the motion of satellites. A measurement of this ‘frame-dragging’ effect confirms Einstein's theory. General ...
