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

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 ...

Scientists observing a dramatic cosmic outburst have confirmed a prediction first explored in Albert Einstein’s work on ...

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 ...

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 ...

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 ...
