Copernicus and the trial of Galileo

Heliosentrism was the idea that the sun is the center of the earth. This was proven by science in the 16th century but it went against the church's geosentrism , so the church did everything in it's power to stop it. Since the church was so powerful they got the person who tried to teach the world Heliosentrism arrested and banned from teaching plus all Heliosentrism books were banned and removed from stores. They had a trial for Galileo in 1633 and they said that Heliosentrism could now only be taught as a hypothoseis and not as fact of course that has changed now.
