Quanta Of Space II

Faraday's lines of force were infinitely thin and continuous and filled space whereas the closed lines or loops of quantum gravity are discrete and finite and are space.
The loops are links between points called nodes.
Each node is a quantum of space.
Two nodes are separated by a small area.
Photons are in space whereas nodes are space.
-Carlo Rovelli, Reality Is Not What It Seems (Allen Lane, 2016), Chapter 6.
