Web18 de jul. de 2016 · An introduction to loop quantum gravity is given, focussing on the fundamental aspects of the theory, different approaches to the dynamics, as well as possible future directions. It is structured in five … WebIn the last decade, cosmological applications of loop quantum gravity, a candidate theory of quantum gravity, have started to be rigorously explored. Largely, these investigations have been carried out in the framework of loop quantum cosmology, which is based on using techniques of loop quantum gravity to quantize cosmological spacetimes.

I would like a very simple answer to this question with as little math as possible. In quantum loop gravity, we want to quantize the curvature of space. I understand that: First, we discretize our manifold (let's say we work in 2D, then we will discretize with triangles) Second, we quantize our discretisation: the length of the edges … black and white hooded flannel jacket
