Question

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

Explanation:

The Copernican model (heliocentric) challenged the long - held geocentric view. The option "It was a radical change in people’s understanding of the universe and Earth’s place in it" is correct because the geocentric model (Earth - centered) was deeply ingrained in scientific and philosophical thought at the time. The other options are incorrect: the Copernican model did not propose a new research method (so the first option is wrong), it went against the Catholic Church's teachings (so the third option is wrong), and the idea of gravity affecting motion on Earth is related to Newton, not Copernicus (so the second option is wrong).

Answer:

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