Mr Salza himself confuses what heliocentrism is. At one point he describes it as the Earth and other planets revolving around the Sun and in another he has the correct interpretation that it means the Sun to be the center of the universe. It cannot be both. Copernicus, Clavius, Gregory, Bellarmine and Galileo simply could not conceive of the idea that the Sun and Earth are BOTH in motion and they also had no conception of a Solar system which only starts to be recognised after Newton and Bradley.
