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 ...

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

Today marks the centenary of an experiment which proved Albert Einstein's theory of general relativity - but what exactly is that theory? Dr Matthew Bothwell, an astronomer at the University of ...

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 ...

As new and powerful telescopes gather fresh data about the universe, they reveal the limits of older theories like Einstein's relativity. When you purchase through links on our site, we may earn an ...

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 ...

Physicists found that clocks on Mars will tick 477 microseconds (millionths of a second) faster than on Earth per day, on ...

A team of computational astrophysicists has developed a simulation that explains the behavior of matter around black holes.

While you already may be aware of Albert Einstein and his Theory of Relativity, it’s worth a refresher before we discuss the theory of financial relativity. There’s a famous example of his theory ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...
