Celestial Movements Through Time: Ancient Models of the Universe

The video explores the history of astronomy, starting with ancient Greek models of the universe, which placed Earth at the center. It then transitions to the heliocentric model proposed by Copernicus and refined by Kepler, which placed the Sun at the center. Galileo's use of the telescope provided evidence for this model, showing that not everything revolved around Earth. The video concludes with modern advancements in astronomy, highlighting the use of advanced telescopes and space exploration, which have expanded our understanding of the universe.
