http://bourabai.narod.ru/shtyrkov/evolution-e.htm E. I. Shtyrkov: "At present, vacuum has been experimentally established to be not a void but it is some material medium with definite but not so far investigated features. It was really confirmed by observation of several vacuum effects, for instance, zero oscillations and polarization of vacuum, generating the particles in vacuum due to electromagnetic interaction. Therefore, it was reasonable to assume that this real matter-physical vacuum can possess internal friction due to its small but a real viscosity to result in variation of light-matter interaction. That is, vacuum can affect on the light wave because of certain resistance. This may be a reason for the redshifts observed. (...) The electromagnetic wave is gradually slowing down... (...) The frequency perceived by observers at any point on the light path depends on the light velocity being at the observation time."
http://cosmos.asu.edu/publications/papers/Quantum_vacuum.pdf Paul Davies: "The quantum vacuum may in certain circumstances be regarded as a type of fluid medium, or aether, exhibiting energy density, pressure, stress and friction. (...) This sort of phenomenon is at its most striking in the case of a single atom moving parallel to, but some distance from, an imperfectly conducting plate. The atom also experiences a velocity-dependent damping force due to vacuum friction."
Question: Einsteinians, do photons coming from distant galaxies experience a velocity-dependent damping force due to vacuum friction?
Einsteinians: Shtyrkov is wrong by definition but Brother Paul Davies is right by definition so... No! Help! Help! Divine Einstein! Yes we all believe in relativity, relativity, relativity! Brother Paul Davies speaks of an atom, not of a photon! The atom does experience a velocity-dependent damping force due to vacuum friction because Brother Paul Davies says so but the photon never experiences a velocity-dependent damping force due to vacuum friction because... well... because we all believe in relativity, relativity, relativity! Crimestop! Crimestop! Crimestop!

It includes the power of not grasping analogies, of failing to perceive logical errors, of misunderstanding the simplest arguments if they are inimical to Ingsoc, and of being bored or repelled by any train of thought which is capable of leading in a heretical direction. Crimestop, in short, means protective stupidity."
