Albert Einstein’s theory of general relativity has been remarkably successful in describing the gravity of stars and planets, but it doesn’t seem to apply perfectly on all scales. When you purchase ...

The rapid expansion of the universe has been the most perplexing enigma in physics. To unravel this cosmic puzzle, scientists turn to the fundamental laws of physics, including Albert Einstein's ...

Everything in the universe has gravity – and feels it too. Yet this most common of all fundamental forces is also the one that presents the biggest challenges to physicists. Albert Einstein’s theory ...

Learn how Albert Einstein’s theory reveals that time on Mars runs faster than on Earth — and why that tiny shift matters for ...

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. Now, a newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and ...

A bizarre "cosmic glitch" in the theory of how the gravity of the universe works may have been mended. The strange glitch in Einstein's description of gravity in his theory of general relativity may ...

Einstein's theory of gravity—general relativity—has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own failure ...

For more than 100 years, Albert Einstein’s general theory of relativity has been our best description of how the force of gravity acts throughout the Universe. General relativity is not only very ...

Einstein’s equations were written for chalkboards and paper, yet they now sit at the heart of some of the most visually spectacular simulations ever run on a supercomputer. By folding general ...

One hundred years after Albert Einstein proposed his theory of general relativity, a theoretical physicist, Erik Verlinde from the University of Amsterdam, proposes a revision, suggesting that gravity ...

During a solar eclipse in 1919, Arthur Eddington observed light bending around the sun just as predicted by general relativity, Albert Einstein’s new theory of gravity. Since then, general relativity, ...

It’s official: Antimatter falls down, not up. In a first-of-its-kind experiment, scientists dropped antihydrogen atoms and watched them fall, showing that gravity attracts antimatter toward Earth, ...
