Posts Tagged ‘Loop Quantum Gravity’

According to Loop quantum gravity (LQG), loops are the quantum excitations of the gravitational
field and they are space. Because there is no background space. Only loops over loops and these loops intersect each other just like a net. Interesting fact is that, the points at which loops intersect, i mean at the nodes “quanta of space” ( also called elements of space or grains of space)was found! Two adjacent quanta or elements of space are separated by a surface, and the area of this surface is also quantized. Nodes carry quantum numbers of volume elements and links carry quantum numbers of area elements. These quantum numbers and their algebra looked like the spin angular momentum numbers of elementary particles. So they are called spin network.

Here are few selected articles which should work well to understand spin network.
