For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

Mind = blown.

A recent study proposes that gravity, the force shaping galaxies and anchoring planets, might not be fundamental after all.

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 ...

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

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

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 ...

"So far we have been watching the cosmos like a silent movie, capturing the ripples of spacetime with LISA will be a real game-changer, like when sound was added to motion pictures." When you purchase ...

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 ...
