Speed of light

The Speed of Light is so fast it can go 299 792 458 m/s 


the Speed of light was founded by Ole Romer.

The speed of light is very very fast . the speed of light = 299 792 458 M / S .The light travels 186,000 MI/S. The speed of light is so fast if you were to run that fast around the equator you would go around it 7.5 times per sec. in 1676 by a danish astronomer that was from Paris named Ole Romer came up with the speed of light. Ole Romer first measured Jupiters orbits speed of life which is is 1.75 . The orbital period is known to be 1.769 earth days. The dutch scientist Christiaan Huygens, who first did the arithmetic found a value for the speed of light. Roemer went back to Denmark in 1681 where he pursued a distinguished career in both science and government. He designed and built the most accurate astronomical instruments of his time and made extensive observations. He later served as mayor and prefect of police of Copenhagen and ultimately as head of the State

Ole Romer
Council. Roemer is remembered today of course not for his high political office but for being the first person to measure the speed of light. They use microscopes,binoculars magnifying glass & telescopes to measure.The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its value is exactly 299,792,458 metres per second, a figure that is exact because the length of the metre is defined from this constant and theinternational standard for time.[1] This is, to three significant figures, 186,000 miles per second, or about 671 million miles per hour. According to special relativityc is the maximum speed at which all energy, matter, and information in the universe can travel. It is the speed at which all massless particles and associated fields (including electromagnetic radiation such as light) travel in vacuum. It is also the speed of gravity (i.e. of gravitational waves) predicted by current theories. Such particles and waves travel at c regardless of the motion of the source or the inertial frame of refeand time, and also appears in the famous equation of mass–energy equivalence E = mc2.[2]
