I am not sure what forum category this should go in, but since Cahill's paper (see abstract and link below) claims to be the first evidence for discrete space, which of course supports LQG, this may be the appropriate location. I searched the Physics Forum for Cahill and got zero hits. His theory is rather groundbreaking if true.
Gravitation, the 'Dark Matter' Effect and the Fine Structure Constant
Authors: Reginald T. Cahill (Flinders University)
Comments: 11 pages, 3 eps figures
Subj-class: General Physics
Gravitational anomalies such as the mine/borehole g anomaly, the near-flatness of the spiral galaxy rotation-velocity curves, currently interpreted as a `dark matter' effect, the absence of that effect in ordinary elliptical galaxies, and the ongoing problems in accurately determining Newton's gravitational constant G_N are explained by a generalisation of the Newtonian theory of gravity to a fluid-flow formalism with one new dimensionless constant. By analysing the borehole and spiral galaxy data this constant is shown to be the fine structure constant alpha=1/137. This formalism then also explains the cause of the long-standing uncertainties in G_N and leads to the introduction of a fundamental gravitational constant G not = G_N with value G=(6.6526 +/- 0.013)x 10^-11 m^2s^{-2}kg^{-1}. The occurrence of alpha implies that space has a quantum structure, and we have the first evidence of quantum gravity effects.
