The observed eclipses were furthest behind the predicted times when the earth was furthest from Jupiter. From his observations, Römer concluded that light took

The first person to realize that light does indeed have a speed at all was an astronomer by the name of Ole Romer. In the Dec 7, 2016 Abstract: The discovery of the finite nature of the velocity of light is usually attributed to Rømer. However, a text at. the Paris Observatory Galileo was the first person to clearly conceive of measuring the speed of light. It took a brash young Danish astronomer named Ole Roemer, however, Dec 7, 2016 Rømer's determination of the speed of light was the demonstration in 1676 that light has a finite speed, and so does not travel instantaneously. Applying the relatively inaccurate calculations for the distances between Earth and Jupiter available during the period, Roemer was able to estimate the speed of Jan 17, 2016 The first true measurement of the speed of light came in 1676 by a fellow named Ole Roemer (Rømer). Roemer was observing Jupiter's moon The first serious measurement of the speed of light occurred in 1676, when the Danish astronomer Ole Roemer observed the moons of Jupiter and noticed that It wasn't until later that Danish astronomer Ole Roemer calculated a finite speed of light by studying Jupiter's moon, Io. See animations illustrating these historical Nevertheless, Römer's method provided clear evidence that the velocity of light was not infinite, and gave a reasonable estimate of its true value—not bad for 1675 Mar 7, 2017 Infinite or a finite speed.

In 1676, the Danish astronomer Ole Roemer (1644–1710) became the first person to measure the speed of light. Roemer measured the speed of light by timing eclipses of Jupiter's moon Io. In this figure, S is the Sun, E1 is the Earth Ole Rømer, a Danish astronomer, calculated the speed of light by observing the eclipses of Jupiter's moon during the years 1668–1674. A discrepancy was observed for the time between the eclipses, increasing when the Earth was moving away from Jupiter and decreasing when the Earth was approaching. Ole Christensen Rømer was a Danish astronomer who, in 1676, made the first quantitative measurements of the speed of light. Rømer also invented the modern thermometer showing the temperature between two fixed points, namely the points at which water respectively boils and freezes. In scientific literature, alternative spellings such as "Roemer", "Römer", or "Romer" are common.

The speed of light was then about 1.5 x 10 17 km/sec. or roughly 5 x 10 11 faster than it is now.

The speed of light in a vacuum stands at “exactly 299,792,458 metres per second“.The reason today we can put an exact figure on it is because the speed of light in a vacuum is a universal

2015-04-20 · Ole Roemer, a Danish astronomer in the 17th century, stumbled upon the speed of light during timing observations of the emergence of Jupiter’s closest Galilean moon, Io, from behind the planet’s limb. The point wasn't really to measure the speed of light; Ole Romer is remembered because his was the first experimental evidence that light has a speed at all (contrary to the previous assumption that sight is instantaneous). It was amazement that drew me to focus on his achievement. The average computed over the long time period will exhibit cumulative effect of the speed of light by being noticeably longer or shorter than the average computed over the short time period.
