Ptolemy's model first became a generally accepted model of the universe in the early days of astronomy. This model described the earth as being motionless and occupied the center of the universe.
A table shaking model was proposed by Copernicus, which has come to be referred to as the heliocentric model of the universe. In this model, the earth is depicted as orbiting the sun about its own axis, and so did other planets. The sun now lies at the center of the solar system, surrounded by the planets.
This theory removed the supposed "uniqueness" of the earth among other planets, which sparked outrage, especially from the Roman Catholic church, since the idea was diametrically opposed to the scientific ideas prevalent at that time.
