# bio (long form, separated for readability)
bio: |
  Born in Samos around 310 BC, Aristarchus likely studied in Alexandria under Strato of Lampsacus. He built sundials, observed the summer solstice of 280 BC, and attempted to measure the sizes and distances of the Sun and Moon. His calculation that the Sun was seven times larger than Earth (wildly low, but still enormous by ancient standards) led him to a radical conclusion: something that massive belonged at the center. He took Philolaus's old idea of a central fire and recast it as the Sun, arranging the planets in their correct order around it and suspecting the stars were distant suns. The model was rejected. Aristotle and Ptolemy's geocentric universe held the floor until Copernicus, who knew Aristarchus had proposed a moving Earth but likely never grasped that he'd already solved the whole puzzle.
