The speed of light in a vacuum is an important physical constant denoted by the letter c for constant or for the Latin celeritas ("swiftness"). It is the speed of all electromagnetic radiation, including visible light, in a vacuum. More generally, it is the speed of anything having zero rest mass.

The speed of light when it passes through a transparent or translucent material medium, like glass or air, is slower than its speed in a vacuum. The ratio of c to the observed phase velocity is called the refractive index of the medium. General relativity explains how a gravitational potential can affect the apparent speed of distant light in a vacuum, but locally light in a vacuum always passes an observer at a rate of c.

I color-marked things by relevance. What you do is mix them all together and claim, on that basis, that c is not constant.The speed of light when it passes through a transparent or translucent material medium, like glass or air, is slower than its speed in a vacuum. The ratio of c to the observed phase velocity...
I hope you arent going to claim now that jet planes violate relativistic speed limit daily?In the article Physicists Slow Speed of Light, they slow light down to 38 miles per hour.
from here, it is quite clear what is meant by "speed of light" in the thread afterwards.i want to know why nothing can travel faster than the speed of light?
Yeah, -1 * c.GOD wrote:BMA: Are you imagining that there's a minimum natural speed?BMAONE23 wrote:Would the solution be to state C as the maximum natural speed of light???
