it is derived from GR, it has not yet been able to show that its
low-energy limit is GR.
I wonder if spin networks or spin foam can form a coherent state that
approximates a string, and i wonder whether the perturbative methods
employed in string theory can then be used on such "strings" to show
GR as its classical limit, and quite possibly, construct other
particles.
