In case anyone 'wonders': No, I'm not giving short-shrift to the
so-called "four forces".

I'm not saying that "TD E/I-minimization" is what's been referred to
as "gravity".

The example was selected [as in AoK, Ap10], only to convey a sense
for an all-[nervous]-system-permeating energydynamic.

=Of course=, within nervous systems, the all-permeating-ness of TD
E/I-minimization conforms, rigorously, to the neural topology [just
as what's been referred to as "gravity" conforms to the distribution
of 'matter' in 'space'.

The concept is =Huge=. If 'you' don't get it, it's not because I've
not asked to come and give it to 'you', is it"
