Lättbegripligt och interaktivt om Ole Römers Man kände väl himlakropparnas banor och hastigheter så Rømer kunde räkna ut hur länge månen borde vara bakom Jupiter, drygt 42 timmar. Han upptäckte att More than two centuries before Einstein, using a crude telescope and a mechanical timepiece, Danish astronomer Ole Romer measured the speed of light with Noticing that Jupiter's moon Io seemed to speed up and slow down on a regular schedule as it passed behind its planet, Romer not only concluded that light did En längre historia med mera fakta (fast på engelska) finns här: The Speed of Light.

Ole Rømer first demonstrated in 1676 that light travels at a finite speed (as opposed to instantaneously) by studying the apparent motion of Jupiter's moon Io. This discovery furthered the adoption of the Copernican model of the Solar System, the development of Kepler's laws of motion, and the first measurement of the speed of light. The speed of light, in any medium,which is usually denoted by c, is a physical constant important in many areas of physics.It is denoted by 'c^0' especially in vacuum medium, although the symbol 'c' can be used to refer to that in any medium. Fizeau calculated the speed of light to be 313,300 kilometres per second, which was within about five percent of the correct value (299,792.458 kilometers per second).

Fizeau published the first results obtained by his method for determining the speed of light in 1849.

The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light.

Once it did, however, the speed of light could be easily calculated by taking the diameter of the Earth’s orbit and dividing it by the difference in time between the quickest and longest recorded For example, if we record the Io eclipse interval, i1, when Earth is at location L and the Io eclipse interval, i2, when Earth is at location K, the speed of light will be the distance between L and K divided by (i2-i1). Using this method, Roemer was able to measure the speed of light as 220,000,000 m/s. In 1983, an international commission on weights and measures set the speed of light in a vacuum at the calculation we use today: 299,792,458 meters per second (186,282 miles per second)—a speed From these findings, Romer could estimate the speed of light.

Feb 18, 2013 More than three hundred years ago, Ole Romer measured the speed of light only by observing the periodic shifting of the observed eclipse arrival

Light is propagated from luminous Bodies in time and spends about seven or eight minutes of an hour in passing from the Sun to the Earth. This was observed first by Romer, and then by others, by means of the Eclipses of the Satellites of Jupiter. Newton endorses the case of a finite speed of light. The speed of light was then estimated to account for the seven minute overall variation of the observed interval between successive eclipses. Roemer's estimate for the speed of light was 140,000 miles/second, which is remarkably good considering the method employed.
