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

Einstein’s equations were written for chalkboards and paper, yet they now sit at the heart of some of the most visually ...

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 ...
