Nicolaus Copernicus was frightened and his mind was confused.Although he had tried to ignore them,all his mathematical calculations led to the same conclusion:that the earth was not the centre of the solar system.Only if you put the sun there did the movements of the other planets in the sky make sense.Yet he could not tell anyone about his theory as the powerful Christian Church would have punished him for even suggesting such an idea.They believed God had made the world and for that reason the earth was special and must be the centre of the solar system.
