Thanks! Actually, your materials scientist perspective is perfect for a few of the questions I have been wondering about.
I could be wrong, but I was under the impression that the CMB (a photonic gas) is composed of primordial photons; that they’re not still being generated.
This is my understanding as well. I switched into a thinking mode that explores limits without bothering with what can be achieved in reality. Kind of like how gas volume decreases as temperature goes down. Reality dictates the gas will turn solid at some point. But what if it didn’t? You are much more firmly rooted in reality compared to me, I think.

Since I can (thanks to you), I have now posted my next part here.
