How did copernicus's work challenge the accepted view of the universe?
a: he rejected ptolemy's work altogether, theorizing that the earth was stationary and fixed orbits were not possible.
b: he agreed with ptolemy that the planets moved, but he did not believe they revolved around the earth.
c: he wanted to prove that god created the universe and that science was not involved.
d: he though that the universe had changed since ptolemy's theory.

The correct answer is option B - He agreed with Plotemy that the planets moved, but he did not believe they revolved around the earth.

Nicolaus Copernicus was a Polish scientist who introduced the idea of the planets moving around the sun, contrary to what everyone believed at that time (1500), that the planets moved around the Earth.

The Copernican system was based on the sun as the center of the Universe. In his manuscripts, he also suggested that the Earth rotation was the basis for the rise and setting of the sun.
