The church’s official position for hundreds of years was that the earth is the center of the universe, and that the sun and other planets revolve around it. The main reason they believed this is, let’s face it, humans are pretty awesome. Have you seen the Notre Dame Cathedral? Or the Vatican? They’re amazing! Why wouldn’t the sun want to rotate around us? Oh, because of that whole gigantic mass and pesky gravitational pull of celestial objects thing.
One scientist in particular, a pleasant fellow by the name of Galileo, tried to point this out in a book titled ‘Dialogue Concerning The Two Chief World Systems.’ He wrote that the earth revolved around the sun, as opposed to the other way around. The religious leaders, upon reading his well-researched findings, immediately applauded his sheer genius and switched their world-view to conform to the tenets of science.
… just kidding. They put Galileo on trial for heresy, and forced him to recant loudly to the masses. He was also put under house arrest, while all copies of the offending book were gathered up and destroyed. This did not put an end to the matter – for you see, the earth does revolve around the sun, despite what others wanted to believe, and as more and more scientists peered through telescopes in between discovering electro-magnetism and contracting syphilis, they realized that the famed Italian astronomer had been right.
