The way the fabric of space and time swirls in a cosmic whirlpool around a dead star has confirmed yet another prediction from Einstein's theory of general relativity, a new study finds. That ...

The longest-running project in NASA’s history has completed its mission. Gravity Probe B has finally confirmed that the Earth drags spacetime around as it rotates like a spoon twisting in a jar of ...

Scientists have observed a spinning star dragging space-time along with it, according to a new paper. Physicists today devote a lot of time to trying to disprove the claims made in Albert Einstein’s ...

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 ...

NEW YORK — Solar sails that use sunlight pressure instead of fuel to fly through space have long been touted by space exploration advocates, but the novel space travel method could also be tapped to ...
