The sunspots were what Galileo used to record the 28 day revolution. The model does not explain the horizon. Why are objects, like the sun and moon, falling behind the horizon.. You can get a telescope, I have a very cheap one, and look at the lunar surface and observe the shadow to confirm that it's a sphere. All the images I've seen of the horizon from airplanes show curvature, and it's easy to verify with any paint program, the bulge always in the middle and it falls off on either side equally. Your model does not explain where the data came from, from satellites that have been independently verified by radio signals and from telescopes. You also cannot explain why lie about the most obscure thing in the world?
