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

An artist's impression depicts the accretion disc surrounding a black hole, in which the inner region of the disc wobbles. In ...

Physicists have chased a unified description of nature for more than a century, yet quantum theory and gravity have ...

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 has been the stubborn outlier in physics, resisting every attempt to be folded neatly into the quantum rules that govern the rest of nature. Now a convergence of bold ...

Thomas Smeenk, BA, unveils a proposed conformal invariant, A = E/(hv), explored as a potential bridge between General ...

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 ...

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 ...

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 ...

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 ...
