When you run the math backwards, you no longer get a bang, though. The
speed of expansion doesn't peak to a maximum at the moment of creation.
This would depend on whether time is what we think it is, but that's
another matter entirely. Perhaps the rate of change of time, no that
surely doesn't account for it.
If the bang wasn't as hot, surely the predictions for material
production and whatnot are also out by some margin?

If there was no big bang, then obviously there is nothing to point to
the existence of an echo of it. Whatever the radiation is can be caused
by anything else, and I don't have an explanation for it. I don't
recognise that I need one any more than I would feel a need to explain
where the bible came from if I had a world view that didn't include a
deity.
It would be bad science to assume that the radiation comes from the
low-level production of matter from the cosmic vacuum. That would be a
nice, tidy explanation but I've no reason to treat it as valid.
Seemingly, most of it would date back to the very early universe, if it
was black body radiation, and there may be a point where some process
delineated itself at that point.

There's been lots of people working for a long time on this w.r.t. big
bang, whereas I'm floating some speculation.
I presume that the chance production of hydrogen can also lead to the
chance production of twin, triple and quad hadron units, assuming that
cold fusion isn't possible. What ratio and stuff to expect, pass. I'm
not a mathematician and anyway haven't got the source figures to derive
answers, as you probably realise.
