The geometry of spacetime forms the very foundation of modern gravitational theory, where the elegant interplay between curvature and matter is described by Einstein’s field equations. In this ...

General Relativity, Einstein’s seminal theory of gravitation, remains a pillar of modern physics by describing gravity as the curvature of spacetime. Nonetheless, persistent questions—ranging from the ...

Albert Einstein’s general theory of relativity has been wildly successful at describing how gravity works and how it shapes the large-scale structure of the universe. It’s summed up in a saying by the ...

A century ago, Albert Einstein became famous. Sure, he was already well-known among physicists. But the world at large learned his name only after November 1919, when news broke that his theory of ...

One hundred years ago this Wednesday, Albert Einstein gave the last of a series of presentations to the Prussian Academy of Sciences, which marks the official completion of his General Theory of ...

Get your news from a source that’s not owned and controlled by oligarchs. Sign up for the free Mother Jones Daily. Yesterday I tackled a vexing problem: Is general relativity really that hard to ...

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.

“This study changes the conversation about warp drives,” pronounced Dr. Jared Fuchs, as a transition between science-fiction ...

We are at a critical time and supporting climate journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen environmental ...

This is the first spacetime to be written down in which a warp-drive is not required to have exotic negative energy. That one ...

Under certain extreme conditions Einstein’s general theory of relativity seems to violate determinism, according to an international team of physicists. The group has shown that in a universe ...
