is an interesting little suggestive piece on the connections between quantum gravity and residual electromagentic effects of electrical dipoles in electrically neutral atoms.

Noncommutative spacetime effects and gravitation

Authors: B.G.Sidharth

Comments: 8 pages, based on two papers accepted for publication in Int.J.Mod.Phys.E

Subj-class: General Physics

In recent years Quantum Superstrings and Quantum Gravity approaches have come to rely on non differenciable spacetime manifolds. These throw up a noncommutative spacetime geometry and we consider the origin of mass and a related modification of the Dirac equation in this context. This also throws some light on gravitation itself.
