What happens after death? This age-old question has intrigued humanity for centuries, with countless theories from religious, ...

In a way, general relativity theory's solidity is kind of a problem. That's because even though it's an essential blueprint for understanding our universe, it isn't the only blueprint.

General relativity has withstood perhaps its toughest challenge to date. The theory, which Albert Einstein published in 1916, revolutionized our understanding of physics and the cosmos.

The preparatory manuscript to the theory of general relativity of Albert Einstein, during their presentation a day before being auctioned at Christie's auction house in Paris, Nov. 22, 2021.

Now, in the most comprehensive test of general relativity near the monstrous black hole at the center of our galaxy, Ghez and her research team report July 25 in the journal Science that Einstein’s ...

Einstein threw out the original hand-written manuscript of his theory of relativity when the paper was published in 1905, but made another hand-written copy in 1943 to raise money for the war effort ...

At cosmological scales, Albert Einstein’s theory of general relativity has given scientists an immensely accurate blueprint ...

Einstein presented his general theory of relativity at the end of 1915 in a series of lectures in Berlin. But it wasn’t until a solar eclipse in 1919 that everyone took notice.

The first image of a black hole, captured in 2019, has revealed more support for Albert Einstein's theory of general relativity. The new finding has suggested his theory is now 500 times harder to ...

While the recent observations and analysis agree with Einstein's theory of general relativity, the authors acknowledge that the 100-year-old theory is starting to show its vulnerability.

Einstein's theory of special relativity beautifully marries the realms of space and time. But more importantly for Designolle's team, it also leads to constraints on how fast information travels.

Launched in 2016, the MICROSCOPE satellite was charged with hunting for deviations in the acceleration of free-falling objects. The instrument presented Einstein's theory of general relativity ...
