Seems to me all we can see is back to the point where
things are moving away from our relative position at
less than the speed of light. Did you know that the
red shift is quantitized, i.e. not continuous, even
within the same galaxy?

All parts of any given galaxy are not moving toward or away from us at
the same speed, unless the galaxy is perfectly perpendicular to us.

Is your red-shift issue about the red shift itself, or about the
magnitude of the shift? And if "variable seconds" is the culprit, how
are blue shifted stars accommodated in your model?

True, but consider that the red shift frequencies
are discontinuous, i.e. quantized.

My issue is that red-shifts are not necessarily
100% Doppler effects.

Of course there is gravitational redshift too, but I don't think that is
what you are referring to.

I think you are trying to say that time is variable (forgive if I err)
This means that the speed of light is also variable if only by relation
to that variable time element

Doppler effect is readily observable at audio and RF wavelengths. It is
widely accepted that the effect continues at light wavelengths.

Any effects that alter Doppler at light wavelengths should also be
noticeable at to wavelengths. I have not heard of any such, have you?

This then says that we are not in the "fastest time" zone, because there
are celestial bodies that are blue shifting toward us, or perhaps
not,they are just in a different "time zone"? ;^)

BTW, I erred in my perpendicular statement above. I forgot about
transverse Doppler shift that we would indeed have in a galaxy at right
angles.

The question is: Are all frequency shifts in the
universe caused by Doppler effects? I say no.
I say some frequency shifts are relativity effects.

Which is the gravitational redshift. Or do you propose another type too?

The "expanding" space between two galaxies could be
a relativity effect and the shorter second due to
relativity effects naturally results in a lower
measured frequency.

Could be. My questions alway revolve around just what - or why - the
effect is. The great thing about Doppler is that it works on so many
scales. We should be able to perform experiments that will go a long way
toward determining if such an effect exists.

What I see however is that there are no great anomalies with the
present model. That doesn't make it right, but it does mean it pretty
much fits.

Relativity also works at speeds lower and more local than across the
universe, Astronauts and their craft who orbit the earth are "younger"
than they would have been if they stayed on Earth. We use accelerators
that act consistently with relativity. We probably should see some of
what you are thinking of.

The doppler shift of EM frequency is a relativistic effect, so you got
that sorta right.

The doppler red shift is thought to be because
galaxies are receding from each other. If a
rope stretched between those galaxies doesn't
break with time, what would that imply about
the recession?
