When Copernicus first systematically created his Sun-centered model of the universe, it did not lead to substantially better predictions of planetary positions than the Ptolemaic model. Why not

When Copernicus first systematically created his Sun-centered model of the universe, it did not lead to substantially better predictions of planetary positions than the Ptolemaic model because the Catholic Church, which was the power at the time, stated it was false, and anybody who believed Copernicus and spread the "myth" were excommunicated or even executed. This was because a sun centered universe would mean that everything the Catholic Church had been teaching about how the Earth was the center of the universe would be false. If people believed it, the church would no longer be seen as the infallible authority, so they needed to stop it from spreading.
