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 ...

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 ...

The big thinkers at Aperture explain relativity and how it warps the fabric of spacetime.

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 ...

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...

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 ...

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 ...

In 1905, Albert Einstein revolutionized physics by demonstrating that time is not absolute but relative to the observer's ...
