Copernicus and the trial of Galileo

During the ancient times, Greeks and the Roman Catholic Church believed that the Earth was at the center of the solar system. However this was not true. Aristotle thought that heavy objects fell faster than a small object. That is not true either. Sometime in the 1500's Galileo, according to legend, went up the Leaning Tower. He used a big and small stone. Both stones fell at the same speed. This is true, so Galileo proved Aristotle wrong. The Church eventually accused him of doing that and forced him to say the wrong things. A hundred years later, Isaac Newton proved that the sun was the center of the solar system. That too, is true. We now know that all objects fall at the same speed, no matter the size. We also now know that the sun is at the center of the solar system.
