An Infinite Speed of Light?
For many ages, men thought that light had no speed. It simply was. It was instantaneous. If speed was referred to, it was referred to as infinite. The Greek philosophers generally had followed Aristotle's belief that the speed of light was infinite. However, there were exceptions such as Empedocles of Acragas (c.450 B.C.) who spoke of light, "traveling or being at any given moment between the earth and its envelope, its movement being unobservable to us," (The Works of Aristotle translated into English, W.D. Ross, Ed.; Vol. III; Oxford Press, 1931: De Anima, p. 418b and De Sensu, pp. 446a-447b). Around 1000 A.D., the Moslem scientists Avicenna and Alhazen both believed in a finite speed for light (George Sarton, Introduction to the History of Science Vol. I; Baltimore, 1927; pp. 709-12).
Both Roger Bacon (1250 A.D. ) and Francis Bacon (1600 A.D.) argued against an infinite speed for light. Francis Bacon wrote, "Even in sight, whe •Finding the Speed of Light: The 1676 Discovery that Dazzled the World

Ole Romer, born in 1644, was the son of a sea captain and trained from his youth to read the stars. Raised in Denmark, he attended university in Copenhagen and studied astronomy. He proved himself quite capable and was invited to teach the king’s sons in Paris and be an astronomer at the France’s Royal Academy of Science. Shortly thereafter, he and his fellow scientists were able to determine the distance between the sun, earth, and the other planets throughout the year. At this time, everyone believed that light was instantaneous, including Romer. But when he discovered that Jupiter’s moon, Io, seemed to slow down and then speed up in its orbit around Jupiter, and then discovered that the change in the speed happened in a predictable pattern every six months, he eventually had an eureka moment. He realized that Jupiter was farther away from Earth every six months, and that it must be the light that took longer to travel to him rather than any
