A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the ...

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

Every time a coffee mug drops, a satellite orbits or an astronaut floats, we are watching the same phenomenon play out under ...

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 ...

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

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 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 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 ...
