Loop quantum gravity seems to predict that the speed of light should depend very slightly on the energy of the photon, with, for example, high-energy gamma rays travelling a wee bit slower than ...

Loop quantum gravity might be thought of as the dark horse in the race for a quantum gravity. Nevertheless, it has some remarkable features.

All the latest science news on loop quantum gravity from Phys.org. Find the latest news, advancements, and breakthroughs.

Physicists have recently proposed a test to determine whether or not loop quantum gravity exists. Before understanding the importance of the test (or the test itself), first we need to understand ...

Now, I should note that this is not as cut and dried as it sounds. The researchers calculated some parameters from loop corrections to quantum gravity and used those to modify general relativity ...

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.

In “Loop quantum gravity” Carlo Rovelli explains how he arrived at a background-independent quantum field theory by treating the gravitational field in terms of closed lines or loops. A remarkable ...

To try to illustrate the concept, the Max Planck Institute for Gravitational Physics made the accompanying movie of “ Quantum Spin Dynamics in Loop Quantum Gravity.” It depicts the quantum evolution ...

Is quantum gravity slowing down neutrinos? To this end, the researchers are working to replace the wheel outside their cryostat with a similar wheel or propeller inside it. “Instead of a wheel with ...

Theoretical physicists working in the rarefied field of loop quantum gravity have developed a way to describe elementary particles as merely tangles in space (see “Out of the void”).
