That idea gave rise to spin-foam models [4–6] (SFM) (see also Rovelli’s book [1]). The concept of a spin foam, although not called that at the time, was introduced in the paper "A Step Toward Pregeometry I: Ponzano–Regge Spin Networks and the Origin of Spacetime Structure in Four Dimensions" by Norman J. LaFave.
