Hi Richard...
Your observation on "expectation of reductionists that some 'super theory' may arise from a reduction of present theories" is highly perceptive and echoes Karen Crowther's essay "When do we stop digging?":
"The idea of unification is not just that there be a single theory describing all phenomena, but that it describe all phenomena as the same as fundamentally stemming from a single origin, e.g., as manifestations of a single entity or interaction."
REF: https://fqxi.org/community/forum/topic/3034
In that theory is "formulation of apparent relationships or principles of specified observed phenomena... and knowledge of it's principles and methods"~ Webster
If formulation of relationships requires a Spatial measurement, then a minimum unit of Spatial measurement is fundamental to the theory... i.e. a theory is fundamental only in that it places constraints on formulation.
In that we do not have a model of minimum units of Space and/or Energy, theorizing "what form 'dark energy' might take" is pure speculation.
Accuracy is definitely a matter of observational scale, and at any given time=t, from the observer's scale of observation, if a condition is apparently un-resolved/inaccurate, it might not hurt to immediately report any disharmony to the Cosmic Computer... i.e. in that Energy/Space distribution for the entire field must resolve on each Source pulse, it can not be said to be deterministic, but some fundamental mechanism is "entirely accurate"... precisely so!
To resolve Energy/Space distribution on each pulse, the pulse rate of the Cosmic Computer clock ticks incomprehensibly fast, and digital technology has made a case that altering a single coded bit, can vastly alter the output/functionality of the program, potentially facilitating spontaneous harmonious resolve, at the observer's scale of events.
Digital technology has also extended "observable scales" by means of virtual visual conceptualization... e.g. a logic reduction to an Energy emission equal in all directions from a single Source point, is now a visually verifiable geometry virtuallity... facilitating a "rational" approach for analysis of "effects found, apparently as a result of what we can't directly observe".

Mathematical physics can offer a coherent 'assembly' of the "evidence needed to advance understanding that already exists, but to preserve "Scientific method", that mathematics must provide visual verifiable kinematics from "what we've already found" to the "new way of seeing", and Digital SIM is my computational analysis tool of choice for animating pulsed distribution of minimum units of Energy (QE) over time, as a constant pulse rate, within a CAD environment quantized by a 3D unified field single point origin encapsulation geometry.

Thanks Richard, for voting as a reductionist in this "What is fundamental?" contest, and for your enthusiastic support of my essay.
Have read only a small fraction of essay's, but gotta get to the poll, so expect a bump soon.
