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.

What was the original goal of Ole Romer in his research?

How did Christiaan Huygens contribute to the understanding of the speed of light?

What was the calculated speed of light by Huygens, and how does it compare to the current value?
