Israel,

"Physically speaking, the effect is related to the fact that dissipation damps the higher
frequencies stronger and causes the maximal frequency of the packet to shift to lower
frequencies (longer wave lengths). The redshifting is a property of the packet. No actual
dilation of the different harmonics is needed as in Doppler effect. This means that even a
shghtest dissipation in the interstellar medium will result in a persistent (cosmological)
redshift of the light propagating throughout the Universe.
The important trait of the new model is that the Hubble constant depends on the initial
width of the spectral line investigated. Then, two sources, that are in a close proximity
in cosmological sense, can have different redshifts depending on the width, d, of the
spectral line (as represented by the parameter fi °^ d^^). A more active (hotter) source
(smaller /3 or wider spectral line) will appear to the observer as much more redshifted
than a more quieter (cooler) source (larger /3 or thinner spectral line). This conclusion is
in very good qualitative agreement with the actual experimental observations."
It makes me really scratch my head as to why the entire cosmological community is out chasing multiverses, when they need to be reviewing the details.
