Quote by Al-Biruni: “The Earth's rotation explains celestial motions without further assumption.”

Al-Biruni showed remarkable insight into planetary mechanics, suggesting that the Earth's spinning motion could account for observations of stars and planets. This idea, centuries ahead of its time, proposed a simpler explanation for complex celestial phenomena, challenging geocentric models.

While the geocentric model was dominant, Al-Biruni considered the heliocentric theory and Earth's rotation. His work, such as "Al-Qanun al-Mas'udi," showcased his advanced understanding of astronomy and his willingness to explore radical ideas.
