The Catholic Church supported the Geocentric Theory because it was consistent with religious doctrine that god had made the earth a special place in the universe
1. For almost 1,500 years, the Church supported almost all of Aristotle’s scientific theories as fact

Nicholas Copernicus• A. Copernicus was so fearful of being considered a heretic that he waited until the last year
of his life to publish his theory
1. However, his ideas spread despite Church condemnation and were eventually embraced by others

Johannes Kepler• Johannes KEPLER (1571-1630) an Austrian• He had already accepted the Copernican picture and tried
to use his superior data to see if it could fit better than the Ptolemaic theory.

The Scientific method was championed by Francis Bacon1. He was an English writer who felt that scholars had
assumed Aristotle’s teachings to be truth without testing them
2. He emphasized the need for experimentation over simple observation in arriving at conclusions (scientific method)
