Einstein’s Theory of General Relativity, an immensely important update to Newton's Law of Universal Gravitation, is currently our best approximation of how the universe ticks. But there are some holes ...

Albert Einstein is famous for his theory of relativity, and GPS navigation and nuclear energy would be impossible without the equation e=mc2.

For over a century, quantum mechanics and Einstein’s general relativity have stood as the cornerstones of modern physics, yet their unification remains one of science’s greatest challenges ...

Albert Einstein's theory of general relativity is based on the idea that massive objects cause a distortion in space-time, which is felt as gravity ...

A rare 54-page manuscript featuring preliminary calculations for Albert Einstein’s general theory of relativity sold for about $13 million at auction in Paris Tuesday to an unknown buyer ...

Einstein published a new theory of gravity—the theory of general relativity—in 1915. It would transform our understanding of physics forever. But it’s far from perfect.
