Why the Redshifts of Galaxies Rotating in Opposte Directions Relative to Milky Way Should Have Different Redshifts?

In his Youtube video, Anton Petrov talks about the notion of tired light as an explanation for some strange findings about galactic redshifts (see this).

The observation that the redshifts of distant galaxies are different depending on whether they rotate in the same or opposite direction to the Milky Way is very interesting and unexpected. Asymmetry also increases with distance. Rotation affects the redshift, but the effect should be very small.

Tired light as a mechanism producing cosmological redshift is suggested as a possible explanation of the findings. As described by Anton Petrov, this mechanism leads to many long-known contradictions with cosmological observations, and in my opinion it can be safely forgotten. However, the effect may be real, even though it has been reported by only one researcher hitherto.

Redshift is real and in general relativity it would most naturally be interpreted as a direct evidence that energy is not conserved. In TGD, where spacetimes are surfaces, the explanation for the cosmological redshift is much simpler and consistent with conservation of energy. The 4-D tangent spaces of the 4-D surfaces related to the 3-surfaces corresponding to the detector and the source differ from each other by the Lorentz transformation and this produces an analogy of the Doppler effect. The energy of the photons is preserved, but one could say that they are perceived as if from systems in different states of motion. The projections of the three-surface tangent spaces M⁴ to the sender and the receiver differ by the Lorentz transformation and this results in a redshift.

A possible TGD based explanation for the observed effect relies on many-sheeted spacetime. The light from galaxies rotating in opposite directions would arrive along different space-time sheets, which would be very large. Their Hubble constants would be slightly different. This might also explain the two values of the Hubble constant: the different values would correspond to different space-time sheets for the arriving photons and the direction of the rotation of the home galaxy of the start relative to the direction of rotation of Milky Way could determine the space-time sheet and therefore also the Hubble constant. The universe would rotate on large scales and both directions of rotation would be possible in many-sheeted space-time.
