Around 26:15 he shows with the help of the abstract concept known as the 'celestial sphere' the movement of the sun throughout the year. He presents both the heliocentric and geocentric models.
You might find the work of the following Italian interesting with regard to the heli/geo debate. Simon Shack (not his real name) who has the following forum, takes the position that Tycho Brahe ,who was a Danish astronomer, had it right and Copernicus was wrong. It's not a subject that one can easily join in and discuss due to the need to bring rock solid understanding of mathematics, astrophysics, celestial mechanics etc. to know where strengths and weaknesses of the models lie. But one things is certain, models are just models, here today gone in the future. There is no guarantee that tomorrow both Tycho's and Copernicus models may not be show to be wrong. Such is Science when it works as it should.
Con-19 PsyOp however shows us how this plays out in Reality. Science becomes the slave of Politics/Finance.
Before posting the above I wanted to find out more about who this Simon is. In the process I found this video. You don't need to watch much to be confronted by a very interesting observation by the person in the video. If you listen from 7 min on you will hear something about Simon Shack.
