There’s an adage coined by [Ian Betteridge] that any headline ending in a question mark can be answered by the word “No”.

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 ...

The most surprising element is that a MOND-influenced theory of gravity—also co-authored by Milgrom—explains this unexpected ...

For over a century, Einstein's general theory of relativity has been key to understanding gravity. But new research suggests this theory "glitches" in the farthest reaches of space. That doesn't mean ...

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 ...

It's not a fluke: For the third time, the LIGO gravitational wave observatory has detected ripples in space-time caused when two black holes circle each other at mind-bending speeds and collide. The ...

A new solution to Albert Einstein's theory of general relativity suggests hypothetical gravitational stars that look like black holes could be nested within one another. When you purchase through ...
