A cloud of helium atoms split, scattered and fell under gravity, yet still behaved as if its parts were linked. That is the ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

Quantum gravity is the missing link between general relativity and quantum mechanics, the yet-to-be-discovered key to a unified theory capable of explaining both the infinitely large and the ...

The graviton – a hypothetical particle that carries the force of gravity – has eluded detection for over a century. But now ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

Scientists have spent decades trying to understand how gravity operates at its most basic scale. However, no theory has come close to fully explaining it. Now, though, a new theory could finally give ...

A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept of quantum gravity does not exist. The idea comes from two London-based ...
