Why was Nicolaus Copernicus's theory that the earth orbits the sun so shocking to the people living in the 1500's?

Explanation: The theory by Nicolaus Copernicus that the earth orbits around the sun is a heliocentric model that is still valid today, while the thinking of the 1500's was that the sun and other planets circle around the earth, which is a geocentric model. The geocentric model was the official position of the Church that shaped people's thinking and had a great influence on believers. That's why this heliocentric model was a shock, and it was considered a heresy.

His views went against traditional beliefs, including those of the Roman Catholic Church
