Question

why did many scientists reject the copernican model when it was published?
it proposed that gravity affects motion on earth, which sounded unbelievable to many people.
it supported the teachings of the catholic church during the spread of the protestant reformation.
it presented an unfamiliar method of conducting research and creating new scientific theories.
it was a radical change in peoples understanding of the universe and earths place in it.

Explanation:

The Copernican model proposed that the Sun was at the center of the universe, challenging the long - held geocentric view (Earth - centered). This was a radical shift in understanding the universe and Earth's place.

• The first option is incorrect as gravity affecting motion on Earth was not a key aspect of the Copernican model's rejection.
• The second option is wrong because the Copernican model was in conflict with the Catholic Church's teachings (which supported geocentrism).
• The third option is not the main reason; the issue was more about the model's content (heliocentrism) rather than the research method.

Answer:

It was a radical change in people's understanding of the universe and Earth's place in it.
