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

So far, the most accurate model describing gravity is still Einstein’s theory of general relativity. It states that gravity as we feel and observe it is a kind of side effect of the fabric of ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

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

The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the universe is expanding faster and faster remains one of the most intriguing ...

The nature of quantum entanglement remains an outstanding problem in physics. But Albert Einstein's theories, along with insights from quantum computing, could finally put the mystery to rest. When ...
