Loop Quantum Gravity — Spin Network Simulator

Interactive 3D spin-network / spin-foam simulator: nodes are quanta of space labeled by spin j, edges carry quantized area A = 8πγℓP²√(j(j+1)); click a node for its volume operator, click an edge for its quantized area, and watch the spin foam evolve.

A 3D visualization of the spin networks and spin foams of loop quantum gravity. Nodes are quanta of space labeled by a spin j; edges are quanta of area whose thickness and quantized eigenvalue follow A = 8πγℓP²√(j(j+1)). Build the graph by adding nodes and edges, then watch faded time-slices stack up above it as a spin foam — a discrete, causal history replacing smooth spacetime with granular Planck-scale structure. Click any node for its volume-operator quantum, or any edge for its quantized area.

Interactive 3D spin-network simulator: nodes are quanta of space labeled by spin j, edges are quanta of area whose thickness follows the quantized area operator A = 8πγℓP²√(j(j+1)). Add nodes and edges, click a node for its volume-operator eigenvalue, click an edge for its quantized area, and watch translucent time-slices stack above the graph as an evolving spin foam.
