Description
Fractal abstract illustration depicting Loop Quantum Gravity. In loop quantum gravity, or LQG, space-time is a network. The smooth background of Einstein's theory of gravity is replaced by nodes and links to which quantum properties are assigned. In this way, space is built up of discrete chunks. LQG is in large part a study of these chunks. String theory requires that space-time have 10 dimensions; LQG doesn't work in higher dimensions. String theory also implies the existence of supersymmetry, in which all known particles have yet-undiscovered partners. Supersymmetry isn't a feature of LQG.
