quote: I don't think it slows down. It only appears to.
quote: We don't really know this (light not requiring a medium) for certain.
quote: In any event, my observation here is that one cannot affect the speed of a sound wave.
quote: However, if you listen to the Doppler Effect, by listening to an ambulance for instance, you'll notice that there are more oscillations as it approaches over a period of, say, ten seconds, than when it leaves. Thus, time is compressed, albeit, to the ear. I am saying that light does the same thing to the eye.
quote: The experiment done with the rocket could easily be explained by the effect that gravity has on photons.
quote: There is also the fact that, relatively speaking, it doesn't matter which object is expending energy to achieve a difference in velocity. Relatively speaking, if you sit on either the rocket or in the chair, it's not going to make a difference.
quote: if we had a different medium in which to observe both train and ball, than light, we would see the ball exceed the speed of light.
