Thanks, Russell,
I really do not want to continue - seems side-line to you and side line to
me.
I just cannot keep my mouse shut.
1. The 'nonequilibrium' topics still identify a certain 'cut' within the
boundaries of them, neglecting wider - maybe unobserved/able - effects from
'unrelated' sides.
(see my '3' below) Pertinent to 'closed systems' as well. In (my) wholistic
view nothing is shut of of anything in an intereffectiveness that may
include unknown
elements at the level of our present cognitive inventory.
2. Suppose singularity is "not" - where does the (alleged) GR break down? It
is a 150th consequential idea from a questionable startup-figment and we
just continue to build logically, quantitatively, formally - call it
science. To be clear:
I appreciate and USE the technological marvels based on such questionable
theoretical background. I believe in human ingenuity even on wrong premises.
3.To your last par:
one cannot have it both ways. Einstein (what a comparison to myself!!!) did
not accept all Newton in his thinking and tackled only certain terms in a
new view.
Copernicus did not abide by the well proven Flat Earth and just 'included'
at some points his new ideas. You cannot keep creationism when you think in
evolution.
I may get lost - as you say - but it won't last long. I won't either. In the
meantime I have the luxury of tasting the new ideas. And I feel I am not
alone in these ways
