Introduction to loop quantum gravity
... The quantum nature of three of the four forces, electromagnetism, weak and strong interactions, suggest that gravitational force too should have quantum properties at Planck scales. Loop quantum gravity (LQG) is an attempt to quantise gravity in a non-perturbative and background independent way. Thi ...
