If a man was as big as a Galaxy he must theoretically be able to move faster than light?
That's really fascinating. Can you tell me more about the speed of light and how it was discovered?
Certainly. The speed of light was first measured by Ole Rømer in 1676. He observed the moons of Jupiter through a telescope and noticed that their orbits appeared to be slightly out of sync. He attributed this to the fact that light takes time to travel from Jupiter to Earth. Using his observations, he was able to calculate the first comprehensive estimate of the speed of light.
