I really don't intend to delve into this.  BUT, this is just like sound.  If someone sends a sound signal at you, and you travel at the signal, or if the source is travelling at you, the speed is constant.  The energy of the traveler is taken up in wave compression, thus the higher pitched sound.  Surprise, surprise, if a source is traveling at you, and shines a light, the light will become "bluer" as the energy of the traveler is converted into wave compression.  So you can't push sound over the speed of sound, nor can you slow it down.  You can only impact the frequency, which is EXACTLY how light behaves.

The problem is that light is not just a wave, but a particle, too.  Imagine two cars (particles).  The lead car is going 100 miles an hour and the 2nd is going 80 miles an hour.  If the second car measures the speed of the first, the answer will be 20, not 100.  Now, make the lead car a photon of light and the 2nd car some sort of measuring device.  Instead of the 20 that you'd expect if it was a car, instead you get 100.  Always 100, no matter how fast or slow the measuring device goes.  That does not make any sense unless time changes and the ratio is related to the speed of light.  This has been born out in literally thousands of experiments.

Sound is never a particle, always a wave.  Light is sometimes one, sometimes another.
