How do we know that nothing can travel faster than the speed of light?
But how do we measure the speed of light?
One of the earliest experiments to measure the speed of light was conducted by Ole Rømer in 1676. He observed the moons of Jupiter and noticed that their orbits appeared to shift earlier or later depending on the distance between Jupiter and Earth. This led him to conclude that light does indeed have a finite speed.
