A new theory suggests gravity could possibly be the result of entropy—which would mean everything in the universe would fall ...

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

The universe comes with a built‑in speed cap, a hard limit that shapes everything from how stars shine to how cause and ...

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

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 ...
