I must apologize for not including the background radiation in the discussion.

Your comments are describing the condition in an open multi-galaxy model in which case I agree with you. The background radiation is commonly considered as the residue of the original Big Bang shifted into the microwave spectrum due to gravity. The closed galaxy model is almost identical.

The only difference in the two models is...

The open galaxy model would not have an identifiable back ground radiation source.

While...

The closed galaxy model would be receiving back ground radiation from the oldest reflected images returning from every region of space.
At some point shortly after the Big Bang the galaxy expansion would reduce the mass density to the point that light spectrum shifts due to gravity would be reduced.
At this point in the expansion the spectrum shift into the microwave region would cease and there would be a light image emitted which would orbit in a closed galaxy.
A quasar displays all the properties I would expect from this image.

Are we in agreement?
