Hi RP,
Sorry to be slow getting back to you about red shifts and Lorentz transformations. Red shifts do not need to be related to Lorentz Transformations at all. For example in nearby spiral galaxies that we see edge on one side is red shifted and the other side is blue shifted, while the central portion is not shifted. So in this case the Lorentz transformations clearly do not apply, since the relative angular motion of the whole galaxy should result in a red shift if its time frame is dilated. The blue shift results because that edge is moving toward us and the relative frequency of the light is compressed accordingly. The opposite happens on the other edge that is moving away from us. The frequency of the light becomes more distended or drawn out. There is really not a clear explanation for this in a continuous universe. In a discontinuous universe all motion is a series of quantum jumps in position from frame to frame and space itself is defined by light so relative motions require a relative skipping of space frames which shifts the frequency of light. It also accounts much more directly for the Lorentz Transformations, as shown in “Gravity and the Void: Tip of a Toe Iceberg.”
At very high relative velocities the whole object should be red shifted since its whole relative time frame is distended or slowed down according to the Lorentz transformations. This is presumed to be the case with distant galaxies. There are anomalies however between different derivations of the Lorentz transformations, including Einstein’s derivation.
There is a fair general description of various manifestations of red shift on the Wikepedia.
Also I have posted a new article “Unified Theories, Fantasy & Cosmic Order” on my website at www.cosmic-mindreach.com that may interest you, since it indicates that light is essentially matter in reflux.
The Lorentz transformations cannot apply to expanding dimensions of matter itself in an expanding universe or no expansion could be observed. If matter is shrinking relative to a presumed spacetime continuum that is expanding then the Lorentz contractions can not apply to matter either since they are derived from considerations of relative space-time motions. These motions on a cosmic scale are very complex.
Best regards,
Bob
