As I understand it, the intensity of sound varies inversely with the square of the distance. I expect the same would apply to light.

1b) How does "intensity var[y] [...] by the time light or heat waves from stars have stretched"?

1c) How far do "light or heat waves from stars" travel for them to be "stretched into microwaves" (in an infinite, static, universe)?

These 2 questions restate the problems with current formula that I have mentioned. There is no summation formula for gravitation and formula grav redshift seems to diminish with distance. If I had any background in how to solve these issues it would have been part of the paper.

1d) If, as you say, the universe is static and infinite, why is the intensity of the microwave background not infinite?

I do like the answer by Art. Beyond that I think this and other of your questions consist of conflicting infinities. For example there is an infinite range of wavelengths at the varying distances from the infinite number of sources. Opposite to the question of infinite microwave intensity , at any point there might be none of a specific frequency because there are an infinite number of other possible frequencies for each source beam.

2a) When do you expect to have finished working this out?
Not soon.

Here is your earlier statement:
my earlier statements, in blue to you, dont come through for me to respond to.
To replace i'nterim steps', I could say - during the gradual lengthening of the wavelength of light, its length will match those of microwave waves before ever reaching the infinite length of paep streams.
3a) Please re-state this, clarifying the word 'interim' so that it no longer "confuses the issue here".

3b) Why, in a static, infinite universe, aren't radio waves "near the extreme length where the various infrared wouuld be more interim in nature"?
I suggested earlier that the role of the observer, in our case, the motions of earth may limit the observable length of radiation stream wave lengths.
