The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Astronomers have seen spacetime itself wobble near a spinning black hole for the first time. The discovery, revealed during a star’s destruction, confirms a major prediction of Einstein’s theory of ...

In the 1900s, Albert Einstein unified the concepts of space and time, giving us a useful new way to picture the universe. At the start of the 20th century, physicists had a problem: The speed of light ...

This is the first time that disk-jet co-precession has been clearly observed in a black hole system, which is truly exciting, ...

The first detection of gravitational waves in 2016 provided decisive confirmation of Einstein’s general theory of relativity. But another astounding prediction remains unconfirmed: According to ...

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 scientist studying crystal structures has developed a new mathematical formula that may solve a decades-old problem in understanding spacetime, the fabric of the universe proposed in Einstein's ...
