“ALL OF THE LAWS OF PHYSICS are the same for every inertial observer.”
In particular, “The speed of light is the SAME for all inertial observers, regardless of the motion of the source.”
In other words, “no physical experiment (mechanical, electromagnetic, optical—or any physical law whatsoever) can distinguish between a state of absolute rest and a state of constant velocity.”
And the definition of inertia from http://dictionary.reference.com/browse/inertia
Physics .a. the property of matter by which it retains its state of rest or its velocity along a straight line so long as it is not acted upon by an external force.
So to me light is a constant in “each” Minkowski World/Universal Line. If an Observer A from an inertial World line A was observing light from another moving World line B the light observed would always be viewed depending on no change in median as a constant. But no matter what velocity World Line B is traveling, light would be observed by an Observer IN World Line B the same as it would for an Observer viewing light from World line A. So if there are objects traveling at a relative constant velocity to earth near the speed of light, As long as the object is traveling at a constant velocity Observers on that object would experience light the same way as we do. So we really need to define the fact that the speed of light in a vacuum as a constant relates directly to it’s inertial World line. No speed limit just a physical constant of how light is observed in a specific World line.
So the particles CERN accelerate are traveling at a constant velocity of 98% the speed of light and as a result they would be on their own World Line. If from our World Line we measured light generated from their collision it would and could not be faster than what we observe light to be. But since I state that solving for c in E=mc2 is an acceleration and not a velocity. The energy created could easily accelerate byproducts of the collision to speeds faster than what their constant velocity was at the point of impact. As stated earlier it is impossible to distinguish between a state of rest and a constant velocity. It might be very interesting to see if CERN can accelerate particles to speeds faster than the speed light without any collision. And if this is what they did do then it is even more proof I am right. I would imagine most of the energy required in a High Speed Particle Accelerator is controlling the direction of the particles as opposed to the acceleration.
