Did Pythagoras study the geocentric or heliocentric model?

Pythagoras, who lived in the 6th century BCE, is primarily associated with early mathematical and philosophical ideas rather than a specific model of the cosmos. While he and his followers proposed that the Earth was spherical and considered the central role of numbers in understanding the universe, they did not fully develop a geocentric or heliocentric model. The geocentric model was later articulated by Aristotle and Ptolemy, while the heliocentric model was proposed by Copernicus in the 16th century. Therefore, Pythagoras's contributions predate these models and are more foundational in nature.
