Document Summary
The accepted universe was the geocentric universe(the earth is the center of the universe and everything else are on crystal spheres that go around the planet. ) that is why we see the sun rise from the east and sets in the west. There were six stars which would be in a different path. copernicus studied mars. Copernicus" evidence was the observation of the planets. Copernicus asked a student of his if he would publish the heliocentric model, but do it the day he dies. 1543 on his death bed, he asked his student to publish it. The earth is not the center of the universe, but only the center of gravity. 1545 calculations on mathematics, not physics. if the earth actually moved, then you would expect things on planet earth to move as well. Copernicus was wrong they said - evidence: the authority of the bible and 1000 years of scientific consensus.
