Loop Quantum Gravity

The following sequence visualises the quantum evolution of geometry in Loop Quantum Gravity. The colours of the faces of the tetrahedra indicate where and how much area exists at a given moment of time. The movie illustrates how these excitations of geometry change as dictated by the Quantum Einstein Equations.

Technically, the faces form a complex dual to the graph of a spin network state and the colour shows the amount of spin (area) with which the edges of the graph area are charged.
