I suspect the shape of the curve is due to adding up a whole bunch of
unrelated things with some lower wavelength boundary, just like the
"law of large numbers" theorem, that shows adding up random numbers
gives a normal distribution (bell-shaped curve). The same might be
said of the black body curve (although it has been ages since I've
looked at the mathematics of that).
The peak of the curve at 9000K is probably a coinicidence, although
IIUC, the universe was constantly cooling from the first spit second,
so is the point at which it was 9000K significant in any way?
Anyway - meh - someone else can look into this.
