For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general ...

It stands among the most famous theories ever created, but the general theory of relativity did not spring into being with a single, astonishing paper like the special theory of relativity in 1905.

And this wasn't even his first revolutionary idea. The Special Theory of Relativity came 10 years earlier, in 1905, when Einstein was a patent clerk in Bern, studying patents for timekeeping devices.

Ever wondered what gravity really is? Is it a force, or is there more to it than we know? In this video, we break down the ...

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.

The general theory stands alongside quantum theory as one of the great pillars of 20th-century physics, but where quantum theory had a long and difficult birth, with multiple modifications and many ...

Albert Einstein's theory of general relativity has been proven right again — and this time, physicists have pinned down just how precise it is: Any deviations from his theory of general ...

Einstein announces the general theory of relativity 1915. Albert Einstein had described the special theory of relativity in 1905. The result of Einstein's thinking about light, ...

In 1913, Albert Einstein had stalled in his efforts to construct his general theory of relativity. He pleaded with his friend Marcel Grossmann for a mathematical boost: “Grossmann, you’ve got ...

It's been over 100 years since Albert Einstein published his general theory of relativity. Scientists have been working to prove or disprove the theory for generations, and UCLA professor of ...
