Sights of Saturn

Cassini returned this fantastic photo of Saturn's aurora superimposed on the North polar hexagon. The aurora was photographed at 4 microns on November 10, 2006 and the clouds at 5 microns on June 15, 2008. The aurora has inner and outer components caused by streams of inward and outward magnetic field lines. Concentric lines crowd in on one another near the pole, creating the hexagon. Saturn's poles are hot spots with the highest temperatures of the surface. Heat and polar magnetic fields are clues that Saturn may have formed around a Black Hole.

Off topic comment Louise, but have you seen this paper which appeared in Can. J. Phys. 84 (2006) 933-944:

"A cosmology with variable c", Hossein Shojaie, Mehrdad Farhoudi

Seems similar to your theory although they conclude that c is proportional to t^(-1/5) rather than t^(-1/3).

Quite interesting that papers on this subject make the arxiv. We are still ahead of the game in making c ~ t^{-1/3}. That fits data from supernovae, Sun and Moon.
