Kea always has fascinating posts. Thanks to Kea for encouraging the publishing of these ideas. Progress is being made on a gr-qc article. Though even arxiv has gatekeepers, more and more outlets are becoming available.
Astro.Philica is a new resource. It allows publication of observations and papers without the usual process of peer review. Nigel, Gebar and others, this is something you could use. To demonstrate, I have published a brief observation. When you have digested my 2000 characters, feel free to look around the site.
This observation alludes to a GM =tc^3 solution to the "Faint Young Sun" paradox. The Sun also converts its fuel to energy according to E = mc^2. The upward L/Lo curve is luminosity according to the Standard Solar Model. The green line indicates a level to keep Earth above the freezing point. When c change is factored in, instead of an upward curve the Sun's energy output has been nearly constant. Life on Earth has been able to evolve over billions of years. If c had not changed in the amounts predicted, we would not be around to argue about it.
