When two black holes slam together, they do not simply vanish into darkness, they ring like struck bells and briefly light up ...

Learn how researchers used Einstein’s theory of general relativity to create the most accurate simulations to date.

Here we explore what the theory of general relativity is and how it affects space-time. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. General ...

The cosmos has served up a gift for a group of scientists who have been searching for one of the most elusive phenomena in ...

One hundred years ago this Wednesday, Albert Einstein gave the last of a series of presentations to the Prussian Academy of Sciences, which marks the official completion of his General Theory of ...

For more than a century, gravity and quantum physics have stubbornly resisted a common language, one describing the smooth ...

Einstein's general theory of relativity achieved widespread recognition following its empirical validation in 1919 by observing the gravitational lensing of starlight during a solar eclipse, precisely ...

The supermassive black hole at the center of the Milky Way is the most extreme astrophysical object located within a million light-years of Earth. With an estimated four million solar masses, it's the ...

Score one more for Einstein. A new study has confirmed histheory of general relativity works on extremely large scales. The study was one of the first rigorous tests of this theoryof gravity beyond ...

Wormholes, warp speed, space-time anomalies — science fiction wouldn't be the same without Albert Einstein's general theory of relativity. And in the real world, we would probably also notice a few ...

Clocks tick faster on Mars than they do on Earth, in part because Mars experiences less gravitational pull from the Sun. Now scientists have calculated just how much faster -- 477 microseconds, on ...

Albert Einstein's theory of general relativity has been proven right again — and this time, physicists have pinned down just how precise it is: Any deviations from his theory of general relativity are ...
