what i see coming out of both Loll's Triangulations gravity
and Smolin's discovery of matter in the twists and braids of the geometry state (the spin network)
is that both of these ways of representing the quantum state of geometry-matter EVOLVE BY LOCAL MOVES
where the spinnetwork is locally rearranged, or the triangulation simplices (triangular building blocks) rearrange themselves
and I see TIME becoming realized as the process of these local moves rearranging the state of geometry+matter
(which are aspects of the same thing, same underlying degrees of freedom)
have to go, back later
