Loop quantum gravity (LQG) is a theory of quantum gravity, merging quantum mechanics and general relativity, making it a possible candidate for a theory of everything. Its goal is to unify gravity in a common theoretical framework with the other three fundamental forces of nature, beginning with relativity and adding quantum features.
String Theory For Dummies. Loop quantum gravity performs this feat by trying to quantize space itself — in other words, treat space like it comes in small chunks. In contrast, string theory starts with methods of particle physics and frequently hopes to not only provide a method of creating a quantum …
Loop quantum gravity. Carlo Rovelli. Weaving space – the 3D structure of space in loop quantum gravity can be visualized as a net of intersecting loops. This simple model was built by the author using key-rings, before spin networks and the physical significance of the nodes were discovered.
The two best theories we have, today, in physics – the Standard Model and General Relativity – are mutually incompatible; loop quantum gravity (LQG) is one of the best proposals for combining them in a consistent way. General Relativity is a theory of spacetime, but it is not a quantum theory.

LOOP QUANTUM GRAVITY: LEE SMOLIN. It’s a way to experiment with the ideals of our democratic societies. For example, in science you must accept the fact that you live in a community that makes the ultimate judgment as to the worth of your work. But at the same time, everybody’s judgment is …
