Well, Ptolemy proved mathematically that the earth is the center of the solar system. Mathematics is the most exact of the sciences.
Well, Ptolemy proved mathematically that the earth is the center of the solar system.Ptolemy did not "prove" the geocentric model; he merely demonstrated that the generally accepted geocentric model could be represented mathematically by a system of cycles and epicycles. (To my knowledge, only Pythagoras placed the earth other than in the center of the universe.) Nor did Copernicus "prove" the heliocentric model; here merely demonstrated that the heliocentric model was mathematically simpler than the geocentric model.
