Question

what is some of the evidence used by galileo to support copernicuss model and disprove aristotle and ptolemys?
each planet spins in an epicycle
planets appear to move backward
jupiter has moons orbiting it
the religion and cultural beliefs supported this model

Explanation:

• Option 1: Each planet spins in an epicycle was part of Ptolemy's model, not evidence for Copernicus.
• Option 2: Planets appearing to move backward (retrograde motion) was explained by Copernicus' heliocentric model (due to Earth overtaking other planets), but this was known before Galileo.
• Option 3: Galileo's discovery of Jupiter having moons orbiting it (using his telescope) showed that not all celestial bodies orbit Earth (contradicting Aristotle - Ptolemy's geocentric view where Earth was the center of all celestial motion).
• Option 4: Religion and cultural beliefs were not scientific evidence. In fact, the Church initially supported the geocentric (Aristotle - Ptolemy) model.

Answer:

C. Jupiter has moons orbiting it
