Geocentric universe

Have you ever wondered how it was found out that the earth revolves the sun? Well at one time this was unknown until a man named Galileo came along. He was highly criticized for his views especially by the church because they seemed to go against there teachings, but eventually his views were confirmed and now we know how the solar system is arranged and that we are not at the center of the universe and it all started with a man who was willing to challenge the social norm and risk everything in his time.
