Who came up with Geocentrism?

Answer 1

Geocentrism, the astronomical model that places the Earth at the center of the universe, was primarily developed by the ancient Greek philosopher Claudius Ptolemy in the 2nd century AD. His work, the "Almagest," systematized earlier ideas and provided a comprehensive model of the universe that dominated Western thought for over a millennium. While earlier thinkers like Aristotle also supported geocentric views, Ptolemy's formulation was the most influential in shaping the geocentric worldview.
