... intersecting loops. There is no location of the net, but only location on the net itself; there are no loops on space, only loops on loops. Loops interact with particles in the same way as, say, a photon ... elementary quantum excitation of the field, and in the absence of charges these lines must close on themselves to form loops. Loop quantum gravity is the mathematical descr...
