Live blogging: Vidotto

Now Vidotto describes some of the dynamics of spinfoam amplitudes, and claims that some beautiful work (Barrett, Dowall, Fairbain, Gomes, Hellmann, Alesci…’09) has shown that in the semi-classical limit, one can get some nice classical structures to fall out of the dynamics, e.g. FRW-like geometry.

Conclusion:  Atomism is fundamental, and so is relationalism.  To exist is to interact, to stand in relations.  Fundamentally what exists are processes;  spacetime itself is a process.
