Explanation:
The scientific community is the one that accepts or dismisses theories. Some theories are accepted, and that is because there are enough evidence that support them, while some theories are dismissed as they have been proven over time that they are not correct.

This theory was basically suggesting that the Earth is the center of the solar system. The Sun, Moon, all the other planets that were known, as well as the stars, were all orbiting around the Earth. This has been proven as wrong (except that the Moon is orbiting around Earth), and that the theory is far away from the truth, so naturally once there were enough evidence it was dismissed.
