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

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

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

Einstein's theory of general relativity, published in 1916, built upon his earlier work, including special relativity and the mass-energy equivalence, both published in his "Annus Mirabilis" in 1905.

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 ...

In another verification of the validity of Einstein's theory of general relativity scientists have used two finely tuned optical lattice clocks to make new ultra-precise measurements of the time ...

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 ...
