A century after Albert Einstein sketched out his radical picture of gravity, astronomers have now watched a black hole ...

Astronomers have finally watched a black hole do something Albert Einstein only described on paper: twist the very fabric of ...

A recent astronomical event has provided evidence that black holes twist space and time, supporting a century-old theory proposed by Albert Einstein.

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 ...

Astronomers have detected spacetime itself being dragged and twisted by a spinning black hole for the first time. The discovery, seen during a star’s violent destruction, confirms a prediction made ...

Einstein’s theory of relativity has many strange consequences. Time moves slower for those traveling at high speeds, and massive objects like the Sun deform the space-time in which they sit, causing ...

Even 100 years after Einstein formulated his theory of general relativity, new observations keep confirming its predictions. Now, Australian astronomers have found some of the best evidence of one ...

Earth's spin warps space around the planet, according to a new study that confirms a key prediction of Einstein's general theory of relativity. After 11 years of watching the movements of two ...

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 ...

A team of astrophysicists from around the world has been following an unusual pair of spinning stars for almost 20 years, and now they say the binary system is persuasive evidence of frame dragging.
