Question

A.

C.
that the Earth was not the center of the universe but rather orbited around the Sun
D.
that the pope had no authority and no right to be the head of the Catholic Church

Answer 1

The main cause of Galileo's conflict with the Catholic Church was:

C. that the Earth was not the center of the universe but rather orbited around the Sun.

Galileo supported the heliocentric model of the solar system, which proposed that the Earth and other planets orbit the Sun, contradicting the geocentric view held by the Church at the time. This belief led to significant conflict, including Galileo's eventual trial and house arrest.
