You said: Spectral shift is generally interpreted as analogous to the Doppler effect. Shift to lower energy is equated to a receding source. Observed low energy shifts in all directions is the basis for speculating that the universe is expanding.

I agree a doppler shift is typically considered to be caused by a receding source.
The conclusion of this assumption requires an expanding universe which has some problems with energy balance.
I will not say it is impossible, just that other causes for the doppler shift should be explored.

You said: Human observation of astronomical topography covers a relatively short period of time but it contradicts expansion in view of the observed stability of positional relations within constellations.

Are you referring to objects in our galaxy or other galaxies?

If you are referring to objects in other galaxies, then you are correct we have been here a very short time.
The time required for a the light of a typical galaxy which has a measurable red shift to reach us is probably a billion years.
Observable records are only a few thousand years.

The red shift effect is not a strait line function but accelerates with increasing distance.
This would indicate that what ever is causing the red shift was more prevalent at a distant time in the past.
At this point in time the cause of the red shift may have reduced stopped or reversed to a blue shift as indicated by close galaxies.

Thank you for your comments. May you never be shift-less.
