BOULDER- Black holes, time travel and E= mc^2. They are all related to Albert Einstein's Theory of Relativity. How many of us, though, can actually explain any of it? This year, Einstein's theory ...

A "New Theory of Everything" aims to advance and improve our understanding of gravity beyond what we know from Einstein's Theory of Relativity. For years, scientists have tried to combine gravity with ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. In 1963, Roy Kerr, a New Zealand-based mathematician proposed a set of equations that explain the properties of rotating black ...

In October 2015, a young mathematician named Clemens Sämann was flying home to Austria from a conference in Turin, Italy, when he had a chance encounter. He found himself seated beside Michael ...

Albert Einstein is arguably the most influential scientist of the 20th century. His general theory of relativity changed our understanding of space and time, becoming one of the two pillars of modern ...

What if the Big Bang didn't begin with a singularity? This point of infinite density, which so divides physicists, could be ...

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 ...

After Albert Einstein published his special theory of relativity in 1905, he spent the next decade trying to come up with a theory of gravity. But for years, he kept running up against a problem. He ...

Einstein's theory of general relativity has passed its toughest test with flying colors, a new study reports. General relativity, which Einstein proposed in 1916, holds that gravity is a consequence ...
