Quantum Gravity Theories: Can they now be tested?

Almost every quantum gravity theory is reviewed here by Professor Aurélien Barrau, a physicist and philosopher at the Université Grenoble Alpes. Barrau explain how each of the many competing theories of quantum gravity may come into contact with experiment. He covers: 00:00 introduction 00:43 String Theory 4:15 Loop Quantum Gravity 6:07 Non Commutative Geometry 8:08 Causal Sets 10:55 Asymptotic Safety 13:14 Causal Dynamical Triangulations 14:46 Horava Lifshitz Gravity
