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 ...

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

Wormholes sit at the edge of science and storytelling, promising shortcuts across the cosmos and even pathways through time.

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

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 ...

Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

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 ...

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 ...

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

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 ...

I've been trying to explain quantum physics, forces, relativity, and space-time to my kid and we had a question that I'm finding difficult to find a solid answer to. Background you can skip if you ...

A supermassive monster lurks at the center of our galaxy, and astronomers have now discovered that it’s spinning so fast it’s warping the very fabric of spacetime into a football shape. According to ...
