>Lorentz transformations are special relativity, no deflection of light
E=MC^2, C^2 is determined by dielectric permittivity and magnetic permeability of the local region of space.
Since a galaxy is not free space, light will experience a small downward shift in frequency relative to an observer.

The same thing happens in an optical fiber, where the speed of light is slows down as it passes through the fiber.
The output wavelength can be slightly lower than input due to hysteresis in the dielectric.

The point is that there are many potential models to explain a phenomena, that use standard and well-explored formulas to get there.

As long as I have a semi-expert in current model,
does the system really interact at all with electrodynamics anymore, or are the constants of vacuum permittivity and permeability left as floating/arbitrary variables?
