Copernicus and the trial of Galileo

The geocentric theory was created by the greeks. It states that the earth is the center of the universe. All the other planets and the sun revolved around it. All everyone seen was the earth staying still and everything else moving. That's what lead them to believe this.

The heliocentric came after the geocentric theory. It stated that the earth and all the other planets revolved around the sun. Nicholas Copernicus came up with that theory. But Galileo proved it. 

The catholic church did not approve of this theory. They said it was blasphemy. So the put Galileo on trial and forced him to say he was wrong. On top of that they gave him house arrest. But he was right.
