It’s time we talked about loop quantum gravity. What exactly is it? What are the loops? And can it really defeat string theory in our quest for a Theory of Everything? PBS Space Time is ...

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

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

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 ...

It depicts the quantum evolution of geometry in Loop Quantum Gravity, with the colors of the faces of the tetrahedrals indicating where and how much area exists at any given moment. It’s also pretty ...

Loop quantum gravity (LQG) is a non-perturbative, background-independent approach to quantising spacetime that seeks to merge the principles of quantum mechanics and general relativity. In this ...

(PhysOrg.com) -- As a quantum theory of gravity, loop quantum gravity could potentially solve one of the biggest problems in physics: reconciling general relativity and quantum mechanics.

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”).
