One thing I have thought a lot about is the varying declination of the Sun which Simon explains so well in the picture below. The only reasonable explanation for the rapid declination of the Sun in Spring and Autumn is that the Sun is moving at an angled orbit around us. In the summer months we see the Sun "staying" high in the sky because we have its angled orbit "in front of us". I'm poor at explaining this, I know. Go read Simons chapter on this in his book instead :-)
But if you get what I mean, think about how this would appear if the Earth was moving around the Sun with a tilted axis. Then the change of declination would be constant during the year. I think not even Kepler would argue that the Earth would change it's speed in his suggested elliptical orbit at a rate that would accord for this. That would be absurd.
Now imagine how we could demonstrate this with a 3D animation. We have a camera with and Eartly viewpoint that looks at the Sun as it goes around the Earth. The declination speeds would match what we can observe in the real world. Now have another animation with the same camera but where the Earth moves around the Sun with a tilted axis. The declination speeds would not vary the way they observably do.
I will implement an Earth view camera into Tychosium 3D eventually, and when that's done I will make a small Copernican model as well to illustrate this. But I have a lot on my table right now, and I'm also thinking why should I be the only one doing these historical animations that visually show that the TYCHOS model is the only one that works with actual observations? Anyone that has the time and skill to do some 3D modelling could do this. So this is a call out. Put your mark in history and make this animation! All required is a globe orbiting another globe (revolving) and a viewpoint from the center globe and the opposite for the Copernican model.
And also, anyone with programming skills are welcome to join the Tychosium team. I've tried reaching out in some programming circles, but everyone seems to freak out when they realize it's about questioning the oh so holy Copernican model, which by the way only makes me even more determined to help put and end to this mass delusion with some crisp 3D visuals. But one guy can only do so much I guess.
If you're interested in joining send me a private PM. I will introduce you to the current T3D code.
