String theory is perhaps the most high-profile candidate for what physicists call a theory of everything – a single ...

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 ...

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 ...

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

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”).

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 ...

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 ...

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