Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...

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 ...

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 ...

Scientists have confirmed, for the first time, that the very fabric of spacetime takes a "final plunge" at the edge of a black hole. The observation of this plunging region around black holes was made ...

Lorentzian geometry forms the mathematical cornerstone of modern spacetime theory by providing a framework in which the causal structure and metric properties of the universe can be rigorously ...

The original version of this story appeared in Quanta Magazine. At the beginning of time and the center of every black hole lies a point of infinite density called a singularity. To explore these ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

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

A violent stellar disruption recorded in 2024 has given astronomers their most comprehensive evidence yet of a black hole twisting the very fabric of spacetime around itself. This effect is known as ...

The big thinkers at Aperture explain relativity and how it warps the fabric of spacetime. House fails to override Trump's ...
