Galileo, in order to measure the speed of light, performed this simple experiment: He and his assistant each took a lantern that had a shutter in front of it, and stood on hilltops one mile apart in the night.
Galileo was to flash his lantern, and the assistant was to open the shutter of his own lantern as soon as he saw the light from Galileo's lantern. Galileo had planned to measure the time taken for light to travel from one hill to the other and back, and calculate the speed of light using the formula, Speed = distance travelled / time taken. But he could not measure the speed of light using this method.
The time taken for the light to travel would have been ( too little, too much, average ) to have been measured by them.
