About C - Speed of Light
A Bit of History
The so-called "speed limit" of the universe, the speed of light was originally quantified in 1676 by Ole Romer. He measured Jupiter's satellite Io's revolutions during different times in Earth's revolutions and came up with a value of 220,000,000 meters/second. Many experiments and centuries later, the speed of light is now an accepted defined constant, represented by the letter c, and made famous by Albert Einstein in his energy equations:
E=mc Travelling close to the speed of light will take years off your age. Speed of Light in a Vacuum: 299,792,458 m/s.
