In the domain of physiology, basic atomic structure is heterogeneously dense enough that decoherent states predominate even microscopically, with matter's motions differentiated by trillions upon trillions of wavicle asymmetries, giving rise to what can approximately be termed interference. Because of the asynchrony produced by extreme variability in density contours, coherence tends to endogenously occur within an organic body only at quantum scales, a situation in which the physics of matter fields is equivalent to the physics of quantum fields. As biological evolution proceeded, organisms developed mechanisms for harnessing quantum coherence, in enzyme catalysis, photosynthesis, and electrical properties of the neuron. Technologies have also utilized quantum coherence in electronics, lasers, computers and more. But these systems, both organic and artificial, are deeply connected to principles modelable with the Newtonian physics of macroscopic objects, a maximally intuitive interpretation regarding matter as in a state of decoherence even while it moves. This assumption that decoherence exists as the default state allows humans to supplement the interface of proprioception with environment in extremely efficient ways, and is core to human toolmaking, object fabrication, and the species' survival.

Proprioception's material basis, as was indirectly theorized by James Clerk Maxwell and scientists of a similar bent, seems to be the extremely probable fact that, within density contours of matter's approximately wavelike structure, loci of maximum energy exist, which in the present day we know are generated by interaction of nuclei with the surrounding field. The relative orientations and forces of nuclear fields along with their effects on the total field are what we call electromagnetism, inducing loci of maximum energy concentration within the density contour that we know as atoms. If both position and motion of distinct instances of matter are hypothetically identical, greater density or ''mass'' implies more constituent energy and more inertial resistance against transitioning from a standing to traveling wave, whether this energy is a beam of electrons or a basketball.

Within an atom, still more finely differentiated loci of energy concentration we model as electron orbitals absorb and emit energy as photons. This is deceptive because even though absorption and emission of light by ''orbitals'' is rather straightforwardly quantized in the textbook case, the total electromagnetic field radiates predominantly as an unquantized wave while amongst atomic wavicles, undergoing subtle, extremely complex energy transitions when perturbed by atoms. As per conservation laws, the energy transition at contact affects atomic wavicles as well, increasing or decreasing chemical vibrations as heat and modulating atomic wavelengths, though knowledge of how exactly this interchange works remains rudimentary. Entire atoms and molecules as defined by nuclear fields do not ordinarily move at speeds that relativistically increase mass to a degree having measurement significance, but the electrons and photons that interact within the scope of nuclear fields do. When electrons attain these speeds, their energy density as mass increases slightly. Light which electrons emit reaches lower frequencies the more these electrons are accelerating and thus subsisting in a less dense state within the bounds of their coherence upon energy release, and reaches higher frequencies the more that electrons are decelerating upon energy release, a more dense state. Thus, an x-ray machine emits braking radiation as high energy x-rays, and accelerating current within a radio antenna emits low energy radio waves. Matter somewhat hotter than temperatures typically reached at Earth's surface emits greater amounts of ultraviolet and visible light due to more rapid vibration, corresponding with larger electron energy density - relativistic mass - to do higher energy radiating. This effect could be explained by the density contour within an atom becoming more pronounced so the proportion of diffuse, highest velocity space increases while loci of greater density become much more compactly massive, similar in concept to a complex combination of centripetal and centrifugal forces.

Physiological matter is extremely dense and assymmetric, interference-laden and decoherent, so endogenous structure and motions of the underlying nonlocal substrate, which in different conditions can perturb at faster rates than the speed of light, align closely with a model that assumes the quantum/classical divide. Except for pockets of nanoscale machinery where quantum states have adapted to function with extreme degrees of coherence, these systems can be viewed mostly as decoherent and pervasively classical. But coherence as the underlying, more nonlocally active substrate of matter is not essentially electromagnetic or even quantum. We should not be surprised then if further research leads to proof that standing and traveling waves of coherence within the nonlocal substrate can perturb electromagnetic matter, the field's core densities, near-instantaneously at quite remote and macroscopic scales from the perspective of current physics, especially if this matter is much more diffuse and homogeneous than an organic body. Beginning to model perturbations of the total coherence field, relying partly on more determined analysis of this field's correlations and interactions with coherence of electromagnetic matter at the quantum scale, in organic bodies and undoubtedly elsewhere, may initiate the next scientific reuolution, surpassing current models to fully bridge the gap from quantum theory to coherence field theory.

A complete realist foundation might be possible!
