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

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

Scientists could soon test Einstein's theory of general relativity by measuring the distortion of time. General relativity states that gravity is the result of mass warping the fabric of space and ...

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

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 ...

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 ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

Solar eclipses occasion lots of excitement and pique the public's interest in astronomical phenomena. Eclipses can also expand our understanding of the universe in profound ways. In fact, astronomical ...

July 26 (UPI) --It's been more than a century since Albert Einstein published his theory of relativity. And while new research shows that it remains intact, they also say new questions have arisen. A ...

Astronomers have observed a star wobbling in its orbit around a ravenous supermassive black hole that is ripping it apart and ...
