The universe’s accelerating expansion has long puzzled physicists. For decades, dark energy, an unseen force thought to make ...

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 ...

Every time a coffee mug drops, a satellite orbits or an astronaut floats, we are watching the same phenomenon play out under ...

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 ...

The following is an excerpt from The Gravity of Math: How Geometry Rules the Universe by Steve Nadis and Shing-Tung Yau. Copyright 2024. Available from Basic Books ...

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 ...

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 ...

A straightforward math tweak could bring tachyon fields into line with the rest of physics. Tachyons are faster-than-light particles, and tachyon fields are special cases of quantum field. The math ...

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 ...

In 1915, Albert Einstein published the Theory of General Relativity, revolutionizing our perception of the universe. In the theory, space and time are a fabric, permeating even the furthest reaches of ...

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.
