The nodes in a quantum network don’t necessarily have to be computers; they can also be atomic clocks. The cesium atoms that ...

What exactly is gravity, and how does it work? From Newton’s early groundbreaking discoveries to Einstein’s revolutionary ...

As a result, alternative theories have emerged—string theory, loop quantum gravity, asymptotic safety, and others—all aiming to fill this gap. Still, none have offered a complete, ...

All the latest science news on loop quantum gravity from Phys.org. Find the latest news, advancements, ... researchers have ventured deep into the realms of string theory, loop quantum gravity, ...

That is the provocative assertion behind Professor Ginestra Bianconi’s latest work, which reframes gravity as an emergent phenomenon arising from the interplay of spacetime geometry, quantum ...

This is what the notorious string theory attempts to do, as does loop quantum gravity, currently considered a frontrunner. But again, neither of these notions quite seem to fit as well as Einstein ...

Detection of the graviton would allow us to confirm gravity’s quantum nature, and even to test our theories of quantum gravity, such as string theory and loop quantum gravity. We’ve talked ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

While the electromagnetic, weak, and strong forces are described by the Standard Model of particle physics, gravity remains an outlier—resisting efforts to be fully explained by quantum theory.
