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 ...

We've all heard of relativity, but what is it? How does it relate to light and motion? So we've all heard of relativity, right? But... what is relativity? And how does it relate to light? And motion?

A new study validates Einstein's theory of general relativity in a distant galaxy for the first time. This study supports our current understanding of gravity and provides more evidence for the ...

For the first time ever, researchers have watched a star race past the supermassive black hole at the heart of the Milky Way, verifying that its motion showed the effects of general relativity, as ...

The big thinkers at Aperture explain relativity and how it warps the fabric of spacetime. Experts warn the internet will go down in a big way — and you'd better be ready ...

(via Minute Physics) This video covers the General theory of Relativity, developed by Albert Einstein, from basic simple levels (it's gravity, curved space) through to the concepts of how curved ...
