Using Verlinde's argument, Smolin shows Loop implies Newton's law of gravity in the appropriate limit. Verlinde's recent paper has thus supplied LQG with a missing piece of the puzzle. Smolin's paper presents his perspective on the significance of the Jacobson 1995 paper and of Verlinde's recent contribution---the basing of spacetime geometry on thermodynamics (basing gravity on entropy.) http://arxiv.org/abs/1001.3668 Newtonian gravity in loop quantum gravity Lee Smolin 16 pages (Submitted on 20 Jan 2010) "We apply a recent argument of Verlinde to loop quantum gravity, to conclude that Newton's law of gravity emerges in an appropriate limit and setting. This is possible because the relationship between area and entropy is realized in loop quantum gravity when boundaries are imposed on a quantum spacetime."
