People tend to think that proponents of an Earth-centered solar system were nothing but intransigent religious fanatics. In fact, they included scientists of Galileo-level genius, like Ptolemy and Aristotle. When their theories were weakened and their opponents’ strengthened, they switched sides — and the “scientific consensus” changed.
From wiki:
Aristotle, 384–322 BC
Claudius Ptolemy, c. AD 100 – c. 170
Galileo Galilei, 15 February 1564 – 8 January 1642
Aristotle and Ptolemy couldn't "change sides", Josh. They'd been dead over a thousand years.
