RE: [Vo]:THE VACUUM, LIGHT SPEED, AND THE REDSHIFT
Kevin, you don’t have to convince me but mine is still a relativistic perspective where C ALWAYS seems like C from the perspective of the local observer inside the Casimir cavity who is unaware he is being time dilate.

It has already been mentioned that an increase in vacuum energy density will result in an increase in the electrical permittivity and the magnetic permeability of space, since they are energy related. Since light-speed is inversely linked to both these properties, if the energy density of the vacuum increases, light-speed will decrease uniformly throughout the cosmos. Indeed, in 1990 Scharnhorst [48] and Barton [20] demonstrated that a lessening of the energy density of a vacuum would produce a higher velocity for light. This is explicable in terms of the QED approach. The virtual particles that make up the seething vacuum can absorb a photon of light and then re-emit it when they annihilate. This process, while fast, takes a finite time. The lower the energy density of the vacuum, the fewer virtual particles will be in the path of light photons in transit. As a consequence, the fewer absorptions and re-emissions which take place over a given distance, the faster light travels over that distance [49, 50]. However, the converse is also true. The higher the energy density of the vacuum, the more virtual particles will interact with the light photons in a given distance, and so the slower light will travel. Similarly, when light enters a transparent medium such as glass, similar absorptions and re-emissions occur, but this time it is the atoms in the glass that absorb and re-emit the light photons. This is why light slows as it travels through a denser medium. Indeed, the more closely packed the atoms, the slower light will travel as a greater number of interactions occur in a given distance. In a recent illustration of this light-speed was reduced to 17 metres/second as it passed through extremely closely packed sodium atoms near absolute zero [51]. All this is now known from experimental physics. This agrees with Barnett's comments in Nature [11] that The vacuum is certainly a most mysterious and elusive object...The suggestion that the value of the speed of light is determined by its structure is worthy of serious investigation by theoretical physicists. http://www.ldolphin.org/setterfield/vacuum.html

RE: [Vo]:THE VACUUM, LIGHT SPEED, AND THE REDSHIFT
Fran, The important paper in this fine write-up is from Barton in 1990 - Faster-than-c light between parallel mirrors . the Scharnhorst effect rederived. Definitely an oldie but goody. it is the essence of the entire piece. http://www.sciencedirect.com/science/article/pii/037026939091224Y The most interesting subset of this phenomenon could be a situation where the mirrors are the reflective walls of hollow nanoparticles.
