How to practically measure the speed of light?
Speed of light is considered in E=mc^2 formula
Additional Details
@Pearlsawme,
Do you think radio signals = light?
How did the speed of light = 299 792 458 m/s was measured, when long distances were unknown/ accessible?
Is speed of light just a relative hypothetical trick?

@Chris Pitchr,
Distances to moons of Jupiter, Jupiter, stars, etc from Earth can be observed using proportionate distances and the varied times of movement/appearance.
Isn't it a guess work to assume the accuracy of such long distances, speed of light and measurement of light (light years), when standing on quick sand (all are relative assumptions)?
Day-light crimes are hard to solve with more/no public evidence! The most obvious may have flaws!!
