Rowbotham never adequately explains his alternative astronomy. If the Copernican theory so adequately explains planetary motions, why discard it, and what would he use in its place? What is the sun orbiting around once a day and how does it work like a spotlight, not a 'point source'? If the moon is self-luminous, what creates its phases? If gravity appears to work here on earth, why doesn't it apply to the celestial objects just a few hundred miles up?
To make his system work he had to throw out a great deal of science, including the scientific method itself, using instead what he calls a 'Zetetic' method. As far as I can see this is simply a license to employ circular reasoning (e.g., the earth is flat, hence we can see distant lighthouses, hence the earth is flat).
This isnt helping your case...
