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

Black holes, these extreme cosmic entities, might well hold the missing clues to solve one of physics' greatest mysteries: ...

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, ...

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 ...

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.

Loop quantum gravity, by contrast, reformulates general relativity in a background-independent manner, quantising space-time itself through discrete structures.

Quantum gravity theories predict that gravity can lead to the creation of entanglement between two masses, ... spawning various theoretical frameworks such as string theory and loop quantum gravity.

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.

The most prominent approaches, like string theory and loop quantum gravity, may have made progress, but they struggle to make testable predictions. So what if we’ve been looking at it the wrong ...
