How Jupiter’s Moons Showed Us the Speed of Light

The video explores the history of understanding light's speed, from ancient Greek debates to Ole Romer's 17th-century discovery using Jupiter's moons. Romer's observations led to the realization that light has a finite speed. Christiaan Huygens later calculated this speed, coming close to modern values. Despite initial goals to aid navigation, Romer's work significantly advanced scientific knowledge.
