Once the light enters the ruby, its speed is slowed down to around the speed of sound (approximately 741mph) and the spinning motion of the rod drags the light with it, … The possibility that the speed of light is not a “constant” after all and has been slowing down is highly controversial and conjectural. The speed of light is a constant. [1]. In fact, there is a deep space probe that has an on board experiment to determine if that's true or not. In this animation, the speed of light appears to be quite fast-, however, the film likewise demonstrates how finite it is. If our world had no atmosphere (air refracts and slows down light a little bit), a photon skimming along its surface could lap the equator nearly 7.5 times every second. This photon, which is identical to the first, travels at the speed of light until it is absorbed by another atom and the process repeats. According to relativity theory, an astronaut traveling at close to the speed of light will not get old as fast as those she leaves behind on Earth. Many different measurements of the speed of light have been made in the last 180 or so years. How fast light travels relative to Earth. Earth is 24,901 miles around at its center. One of O'Donoghue's first animations shows how fast light moves in relation to Earth. Yet, some of the most dramatic changes in scientific perspective come only after much debate, vigorous opposition, and the like. How to slow down light until it stops In vacuum, light always travels at a constant speed of 299,792,458 metres per second. Quote: On Sat, 24 Jan 2015 07:38:27 +0100, Poutnik
