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 ...

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

Scientists observed a spinning black hole dragging space and time as it tore apart a star, confirming a key prediction of Einstein’s theory of relativity ...

California-based startup Relativity Space is one of many launch startups, but it stands out for its 3D-printing approach to manufacturing rockets while also pursuing fully reusable rockets. Relativity ...

This temporal lag is a direct consequence of Albert Einstein’s Theory of General Relativity. The rule is simple: the weaker ...

If you're going to Mars you'd best take along a jar of anti-aging cream because while you're there you're going to age faster ...

Clocks tick faster on Mars than they do on Earth, in part because Mars experiences less gravitational pull from the Sun. Now scientists have calculated just how much faster -- 477 microseconds, on ...
