Ole Romer gave us one of the first accurate evaluations for the speed of light. The problem is, did he also prove that 'the past' , 'the future', 'time', 'seconds etc', and 'times arrow' all exist, or, did he just prove that light doesn't travel from A to B instantaneously?

Roemer's method can be regarded as a means of measuring the speed of light in the direction from Jupiter to the Earth. Jupiter has an orbital period of about 12 years, so if we use Roemer's method to evaluate the speed of light several times over a 12 year period, we will be evaluating the speed in all possible directions (in the plane of the ecliptic).

Starting with Roemer's 1676 breakthrough endeavors, the Roemer' s greatest achievement, however, was the first relatively accurate measurement of the speed of light, a feat he accomplished in 1676. At the Royal Observatory, Roemer's studies of Jupiter's moon Io and its frequent eclipses enabled him to predict the periodicity of an eclipse period for the moon. The "speed of light" can also mean the speed at which light travels in a given medium. For example, light travels only two-thirds as quickly in glass as it does in a vacuum.

Rømer also invented the modern thermometer showing the temperature between two fixed points, namely the points at which water respectively boils and freezes.

Se hela listan på interestingengineering.com http://demonstrations.wolfram.com/RomersMeasurementOfTheSpeedOfLightThe Wolfram Demonstrations Project contains thousands of free interactive visualizations, 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. How did Ole Christensen Rømer, who in 1676, shortly after Galileo's death, was said to have measured the speed of light as 220,000 km/s by timing the orbits of Io around Jupiter? My only guess is the moon Io orbiting Jupiter is simply a clock.

He stated it to be 220,000 km/s, which is not that different than the modern value of 299,792 km/s. Romer Fiber specializes in large scale project management and installation of high speed data networks.

My only guess is the moon Io orbiting Jupiter is simply a clock. Rømer's argumentation was the reason Descartes' view of instantaneous light propagation was abandoned in favor of the until now accepted view of light traveling at a high but finite speed. His arguments were quite simple, maybe a little too simple, but were universally accepted.
