Today, with advancements in science and technology, the geocentric model seems preposterous.he geocentric model, also known as the Ptolemaic system, is a theory that was developed by philosophers in Ancient Greece and was named after the philosopher Claudius Ptolemy who lived circa 90 to 168 A.D. It was developed to explain how the planets, the Sun, and even the stars orbit around the Earth.
