Likewise, I think of the state of affairs immediately following the
"big bang" as a whole lot more chaotic than the absolute thermal
uniformity of a Universe that, some time far in the distant future,
has reached "absolute equilibrium"

Here it gets hard. As far as I have understood, the answer is that the
universe right after the big bang did have a fair amount of disorder
regarding the _movement_, but back then there wasn't much space to be
disorderly _in_, so the _position_ of things was fairly constrained,
leading to a very low entropy all in all.


HM:

Penrose ( R2R ) does NOT this size/entropy_increase explanation at all.

Surely, I'll be ---NOT EVEN WRONG--- in presenting his view, but ... he
appears to divide entropy contributions into those of Weyl_geometry [ a
huge spacial curvature contributor , and zero at t==0 ) ] and a tiny
entropy contributed by photons/particles.
The enlarging phase_space available to photons ( as the universe expands
) remains insignificant compared to Weyl entropy.

**REM** Somebody kindly -- who knows what they are talking about -- set
out this issue conflict clearly.
