A recent study proposes that gravity, the force shaping galaxies and anchoring planets, might not be fundamental after all.
Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...
Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...
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 ...
Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...
"This is a real gift for physicists as we confirm predictions made more than a century ago." When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.
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 ...
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 ...
