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 ...

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 ...

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 ...

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 ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

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

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 ...

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 collapsing warp bubble like the one seen in Star Trek would set space ringing with gravitational waves. When you purchase through links on our site, we may earn an affiliate commission. Here’s how ...

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

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 ...
