Final answer:
Galileo should have defended his scientific beliefs when charged with heresy by the Catholic Church.
Step-by-step explanation:
Galileo's heliocentric theory challenged the beliefs of the Catholic Church that upheld the geocentric view of the universe. When charged with heresy, Galileo faced the choice of recanting his theory or defending his scientific beliefs. While recanting may have spared him from persecution, it would have hindered scientific progress and the advancement of knowledge. Therefore, Galileo should have defended his scientific beliefs.
