Bill6. As I was writing that post I was aware that it was heading towards the subject matter of your comment. I deliberately stopped short of raising that issue, as I thought it would be of value to deal with some peripheral points first.

I made no mention of tired light for two reasons:

1. I didn't really address redshift.
2. I don't yet know enough about it.

I have a section in my notes from a couple of years ago dealing with redshift/Doppler. I'm just looking for some time to swat up on tired light and add it to those notes.

There never was nothing.
