- Rømer's_determination_of_the_speed_of_light abstract "Rømer's determination of the speed of light was the demonstration in 1676 that light has a finite speed, and so doesn't travel instantaneously. The discovery is usually attributed to Danish astronomer Ole Rømer (1644–1710), who was working at the Royal Observatory in Paris at the time.Rømer estimated that light would take about 22 minutes to travel a distance equal to the diameter of Earth's orbit around the Sun: this is equivalent to about 220,000 kilometres per second in modern units, about 26% lower than the true value. While the exact details of Rømer's calculations have been lost, the error is probably due to an error in the orbital elements of Jupiter, leading Rømer to believe that Jupiter was closer to the Sun than is actually the case.Rømer's theory was controversial at the time he announced it, and he never convinced the director of the Royal Observatory, Giovanni Domenico Cassini, to fully accept it. However, it quickly gained support among other natural philosophers of the period, such as Christiaan Huygens and Isaac Newton. It was finally confirmed nearly two decades after Rømer's death, with the explanation in 1729 of stellar aberration by the English astronomer James Bradley.".
