Abstract. The Cartesian material space approach to Maxwell’s equations reveals the analytical solution of the continuous radial density for the extended elementary charge. Radial charges and their Coulomb fields carry equal passive and active imaginary energies. The Einstein mass-energy formula can be updated for electricity in complex numbers. The Principle of Equivalence works universally for active/passive masses and for active/passive electric charges. Maxwell’s equations for complex continuous charges become 4-vector identities for locally paired flows of energies that correspond to the Chinese yin-yang approach to the nature. Cartesian relativistic physics has its own nondual analog of the Einstein Equation, which leads to geodesic equations for the motion of Ricci material densities and to vortex states of the elementary mass-extension. Non-empty space physics modifies the Navier-Stokes equation by kinematic ‘living forces’. This inertial feedback enables a conceptual choice between Newtonian and Cartesian universes (with localized or extended elementary masses, respectively) because of new predictions of pressure and temperature gradients across laboratory flows of liquids and gases.

Cartesian physics [2, 3] of material space is currently described only in qualitative terms and without quantitative predictions of specific phenomena for the theory verification procedure. This physics refers to Descartes’s natural philosophy [4, 5] which is still ‘The Terra Incognita’ for pragmatic supporters of the dual Newton world with empty space between localized mechanical bodies. The concept of void space regions without matter was unclear to Descartes, who after Aristotle also maintained the extension of matter or ‘matter-extension’ as the continuous material plenum. The Cartesian vortex mechanics for all types of observable spatial displacement in this material plenum was published in 1629. Later Newton’s successful dynamics of point-like masses shook the need in sophisticated matter-extensions with vortex states. Nowadays, Newton’s mechanics of localized masses and continuous gravitation fields in empty space form the dual core of contemporary space theories in the Solar system and beyond. Not Cartesian physics, but Newtonian empty space modeling became mandatory for 1916 Einstein’s gravitation in the weak field limit. No one looked at mechanical theories if they did not fit Newton’s mass transport at low speeds.

Western science invented the motto ‘Nullius in verba’ in a line of mandatory experimental evidence. This pragmatic approach to reality turned out very promising for initial technical progress that took place since the Middle Ages. Western researchers and engineers tend to be independent from any religion and from the influence of any philosophical teachings, including Cartesianism of material space and Chinese reading of immeasurable reality. Recall that the ancient Chinese science has recognized the coexistence of corporeal and incorporeal (immeasurable) worlds that contradict the Western science scope. However, many eastern findings, like the traditional Chinese medicine, are still challenging western researches.

The 1961 Eightfold way of M.Gell-Mann and other formal ‘coincidences’ between modern physics and ancient Eastern dogmas have been mentioned by many authors, for example by F.Capra [6]. Contemporary physicists merely superficially trace the roots of the Standard Model in ancient texts and symbols like the eight trigrams. In conventional scientific publications, the authors avoid referring to Eastern teachings. The latter originated, in particular, from the classic ‘Book of Changes’ (‘I Ching’), a fundamental work in the Chinese history and culture. In general, it would be wrong to say that many leading researchers were inspired by the philosophical treasury, whether it be East or West.

By rejecting invisible material phenomena beyond the limits of laboratory measurements, it is impossible to fully understand, for instance, Cartesian natural philosophy, the yin-yang Chinese dialectics, and the Russian Cosmism [7] principles (“people are citizens of the whole Universe rather than the Earth”). Beginning with Plato, the Ancient Greeks considered space to be a continuous material plenum, filled everywhere by ‘the most translucent kind (Aether)’. Material bodies cannot be replaced, according to Aristotle’s logical proof, to completely empty, intangible place outside the continuous space-plenum. Descartes followed this logical avenue and eventually offered his vortex mechanics for the spatial transport of variable energy charges. Should we neglect Cartesian physics of non-empty space due to ‘laboratory evidence’ in favor of the Newtonian empty space model? The point mass notion has to be conceptually criticized by the relativistic carrier of variable internal energy, which exhibits the proper time dilatation (frequency red shift) in the case of one moving particle or the kinematic cooling in the case of a moving thermodynamical body. Due to low speed changes of bodies’ internal energies, Einstein’s Theory of Relativity better corresponds the Cartesian world of viriable energy charges in the low speed limit than the Newtonian world of constant gravitational/inertial charges. Below we plan to describe this statement quantitatively and to reject Newtonian references from the self-contained metric description of non-empty inertial spaces.

Dual classical physics for spatially separated matter and fields is traditionally assigned to the macroscopic world, while nondual material densities of quantum fields physicists tend assign to only the microscopic world. But the unique physical reality is either dual or nondual regardless of the spatial scaling and mathematical formalisms in available theories. Similarly, the matter is either local or non-local regardless of suitable approaches to describe it. The celebrated Einstein-Podolsky-Rosen paradox initiated the long-term discussion and many tests of the material world nonlocality. Now nonlocality of matter is reasonably considered beyond quantum physics [8]. The world holism [9] and the global direct overlap of all material elements motivates our attempts to develop non-Newtonian mechanics for mass densities of the extended particle. The Newton empty space model vs the Cartesian material space of overlapping extended vortexes is illustrated in Figure 1. There is no in reality a mesoscopic scale for a possible transitions from nondual microscopic physics to dual macroscopic model of Newton. Material states should initially be considered in nondual field terms on micro, macro, and mega scales in qualitative, if not quantitative, approaches to any energy flows within the Universe.

Figure 1: Newtonian particles and empty space vs Cartesian nondual plenum

The purpose of this paper is to trace the balanced energy origin of extended charges in Maxwell’s electrodynamics and Einstein’s metric gravitation, to study strong field energy conservation and compensation for overlapping material elements in terms of complex densities, to propose nondual field analogues of the Maxwell equations and the Einstein equation, and to predict inertial space phenomena for conceptual tests of Cartesian physics in the laboratory. Based on propositions of Aristotle, Descartes, Mie [10] and Einstein [11], we shall try to study how to redesign classical electrodynamics and gravitation in pure field terms (material fields without localized particles) in order to construct a bridge between the Western science pragmatism and the eastern untestable approach to the invisible reality. Our initial idea is that ‘Nullius in verba’ physics may coherently replace the supposed empty space (between the localized charges) with the Aristotle space plenum of charged material fields. This may assist to give up the unnecessary concept of Newton’s point-like particles and to modify the old building of classical gravitation and electrodynamics by strong field solutions without energy divergence.

Nonempty space with a continuous charge density and a density of the continuous mass will have the energy meaning in our computations. All material densities will obey the universal Yin-Yang Principle for local pairing of complementary (passive and active) energy flows. This Chinese principle was rediscovered by Einstein as the Principle of Equivalence for gravitational (passive) and inertial (active) masses of mechanical (corporeal) bodies. Below we prove analytically that the Yin-Yang Principle can be applied to gravitational / mechanical field densities of continuous masses. The same is true for local pairing of active / passive energy densities in Maxwell’s electrodynamics. The yin-yang dialectic suggests in such a way to unify as the charge with its field, as well as electricity with gravity. For this, we used complex numbers, while four known interactions may be unified similarly in algebra of quaternions.

The Einstein Equation in the dual (field + matter) Newtonian paradigm has been known since 1915. The similar tensor equation in the Cartesian paradigm of the united space-matter operates with a nondual field continuum of extended mass-energies. This continuum is filled by radial vortexes with chaotic auto-rotations of elementary metric densities. Such permanent metric motions within the elementary Cartesian vortex reveal the kinematic origin of the rest-mass energy . This active, kinetic energy may be called the internal relativistic heat. The positive (kinetic, active) energy is always accompanied by equal, but negative (potential, passive) self-energy according to the Yin-Yang Principle. Therefore, the mass creation mechanism from ‘the void nothing’ can be quantitatively discussed in Cartesian physics and in Chinese dialectics. There is no elementary inertial mass without vortex auto-rotations of metric space. And circular material densities with positive kinetic energy generate self-gravitation with negative (passive) elementary energies of Cartesian vortex states that results in the global compensation of active and passive energies in the non-empty space Universe.

We will return to the Einstein idea that the geodesic equations of motion should follow from the strong-filed gravitation equation. This was difficult to prove from iterations in the dual post-Newtonian physics. But Cartesian geodesic relations for Ricci material densities can be derived exactly from the nondual field analogue of the Einstein Equation. In order to demonstrate some practical benefits of non-empty space physics, we will modify the Navier-Stokes equation in terms of Ricci energy flows with the inertial feedback of ‘living’ forces, . This dynamical pressure averts asymptotically divergent energy flows and can initiate conceptual tests of Newton vs Cartesian mechanics in the laboratory.

This paper is not a polemical overview of the Descartes philosophical treasury or the known neo-Cartesian approaches to the nature. We focused on the analytical energy balances for the introduced radial charge instead of the point particle in order to reinforce the non-empty space idea for Maxwell’s electrodynamics, for Einstein’s special and general theories of relativity, and for thermodynamics of condensed matter. The following mathematical exercises may be useful also for those researchers of living matter, who would like to look at the world holism and nonlocality beyond the formal procedures of quantum mechanics.


Coulomb fields within continuous charges

The predominant majority of people believe that electric charges and inertial masses are located within the visible frame of macroscopic bodies. Such bodies can be divided into smaller parts in accordance with everyday observations. Thus, the smallest part of substance was introduced as a so-called corpuscle (the point particle in the indivisible limit) that is a carrier of the elementary mass and charge. Classical fields between localized particles in ‘Nullius in verba’ physics are considered massless and chargeless. Nevertheless, the experiment is only a criterion of truth, but not the truth itself. The materialistic pragmatism of highly educated and well-equipped researchers of the supposed dual ‘reality’ (particle and field are different notions) was rejected by many philosophers. Indeed, by dividing an infinitely extended field-energy object into parts one should again obtain only infinite objects rather than corpuscles of limited size.

In contrast to available observations, nonempty space of continuous material flows has been recognized by philosophers not only in the Ancient East and in Ancient Greece, but also by many contemporary thinkers in the West (Mie, Einstein, Infeld) and in Russia (Fedorov, Umov, Vernadsky, Roerich et al.[7]). “A coherent field theory requires that all elements be continuous… And from this requirement arises the fact that the material particle has no place as a basic concept in a field theory. Thus, even apart from the fact that it does not include gravitation, Maxwell’s theory cannot be considered as a complete theory”as was stated by Einstein and Infeld [11] in 1938. Indeed, the postulated point-particle paradigm results in Coulomb divergence, which terminates Classical Electrodynamics as a self-consistent theory. A point source in the Maxwell-Lorentz Equations may be considered as “an attempt which we have called intellectually unsatisfying” according to De Broglie [12]. Einstein also criticized his 1915 field equation for the point gravitational source: “it resembles a building with one wing built of resplendent marble and the other built of cheap wood” (translation [13]). The Dirac delta-operator for point material densities in emptiness seem to have pushed Western physicists far away from the physical reality and Eastern approaches to superimposed energy flows.

Continuously distributed elementary charge was reasonably inferred by Mie in order to derive properties of nonlocal charges from properties of their EM fields and four-potentials. Regretfully, in 1912-1913 the ‘Theory der Matter’ [10] had not found the exact (logarithmic) potential of strong fields within nonlocal classical matter. Therefore, the promising non-empty space concept had not been proven before the mathematical era of quantum non-locality began. Formal probabilities of the delta-operator ‘dice’ in the Newtonian empty space arena postponed search of rigorous analytical solutions for Mie’s nonlocal world of continuous particles.

The classical field equations keep the analytical solution option for a distributed elementary particle. By following Mie, we assume that it is possible to relate locally electric, , and magnetic, , field intensities in the Maxwell-Lorentz equations [14],

(1)

to charge, , and current, , densities of the extended electron. Contrary to Lorentz, the electron’s charge distribution was not postulated by Mie within a microscopic spatial volume (electron’s fields were assigned by Lorentz to charge-free regions or to the supposed empty space around charges). The mathematical equation can be rigorously resolved under the nonempty space assumption by admitting that the elementary charge and its field coexist together in all space points of the infinite Universe. In other words, we maintain that the Mie (and Einstein) idea that the elementary electric (and gravitational) charge is to be inseparably integrated into its spatial field structure with instantaneous local relations (yin-yang pairing).

The distributed radial electron with the analytical material density possesses the same inertial mass density as the gravitational field mass density due to the Einstein’s Principle of Equivalence. This gravimechanical principle is a part of the Yin-Yang Principle for all natural phenomena. By following the Chinese dialectic, the ‘yin’ electric charge density of the extended electron should be equalized with the paired charge density of local Coulomb fields, . In the Einstein-type terminology, the passive charge density of the extended particle numerically coincides with the active energy-charge density of the Coulomb field:

(2)

where and is the universal self-potential for densities of active charges. Such physical relations between the particle’s density and its Coulomb’s field intensity can be found [15] as an exact solution to the Maxwell-Lorentz equations (1),

(3)

in full confirmation that the Yin-Yang Principle equally works for paired active/passive densities of charges in Maxwell’s electrodynamics and in Einstein’s gravitation. The active charge (of Coulomb fields with their energy density and the strong field scale ) has the energy nature under the universal potential like an inertial mass has the energy nature due to the celebrated formula . Maxwell-Lorentz’s equations can be discussed as in dual terms of electric fields and their currents, as well as in nondual terms of paired fields with continuous active/passive charge densities in the conjugated structure of active/passive energy streams. In general, the self-energy of the active charge for electricity should be added to the mechanical self-energy of the active, inertial mass. Potential self-energies of passive charge densities in their own electric/gravitational fields compensate quantitatively energies of active charges. These passive self-energies are infinite for point particles in Newton/Coulomb theories, but can be counted in the Cartesian world of extended elementary carriers of energy.

Now we associate electricity with imaginary numbers by using for the ‘negative’ elementary charge of the electron. Its self-potential is to be defined via the light speed limit and the Cavendish constant . The similar charge to spatial scale ratio, , arises in gravitation of continuous radial masses [15, 16], where is the body internal (kinetic or active) energy. In other words, we use the fundamental potential for self-energies of both mechanical (real) and electric (imaginary) charges,

(4)

in order to extend the Einstein mechanical formula to electricity [17].

Despite that the electron possesses in (4) the imaginary electric energy ( of the imaginary charge ) next to 511 of the real mechanical energy, paired interactions of imaginary electric charges correspond to real Coulomb forces and to real interaction energies. Contrary to an electric charge defined in real numbers, like the inertial mass, the imaginary electric charge exhibits a correct direction of the radiation self-force , which is proportional to . Ultimately, joint densities of mechanic and electric charges can be described in complex functions. Real integrals over spatial densities provide inertial mass-energies, while imaginary integrals correspond to non-inertial self-energies of electric charges.


Superimposition of extended charges with conservation and compensation of active/passive field energies

The strong-field potential within the extended gravitational/inertial charge was introduced [15] for local action on probe bodies and for the local gravitational self-action of massive densities themselves. In this view, the inertial (active, positive, kinetic) energy of the active charge is accompanied by the negative gravitational (passive, negative, potential) self-energy because of the gravitational action of the negative potential on its positive mass-charge densities . Computations provide exact compensation of active (inertial, measurable) and passive (gravitational, unmeasurable) energy integrals for every radial (elementary) carrier of inertia and gravitation,

(5)

This universal compensation of the internal (kinetic, active) rest-mass energy by the negative potential energy from the gravitational self-action, , takes place under the integral mathematical equality . Similarly, radial electric densities in their strong-field logarithmic potential should also lead to compensation of their post-Coulomb field energy. The latter and the potential self-energy are both infinite in the point charge model, but they are finite for strong fields of the extended radial charge in consideration.

The gravity-type Poisson equation, , treats the imaginary (astro)electron as a non-linear field composition with respect to the radial field intensity or the electron’s interaction potential , with and

(6)

This non-linear equation reveals the imaginary post-Coulomb potential with the negative, gravitational sign for the continuous radial carrier of electricity,

(7)

The logarithmic potential (7) reproduces the Coulomb law on measurable scales, for , but with the Newtonian negative sign. Such a Newton-type potential of imaginary charges describes real electric forces, , with the mutual repulsion of like charges and , and the attraction of unlike ones.

The gravitational sign in the Poisson equation for imaginary electric energies suggests to inverse positive and negative imaginary densities of electric charges, , in the Maxwell-Lorentz equations (1). The conventional inversion of electric charge signs for electrons and protons does not change electrodynamic laws of paired interactions. The electrostatic solution for charged imaginary densities in (1) with the gravitational type direction of the radial Coulomb field, , facilitates the unification of gravity and electricity on the basis of one complex energy - charge (4), . The Maxwell-Lorentz equations (1) for the massless elementary charge can be extended to the complex energy flows of the radial carrier with the elementary charge density ,

(8)

Here we replaced the extended charge density in the nondual Maxwell-Lorentz equations with the equivalent density of the local field divergence. The yin-yang field physics of locally paired material densities maintains nondual energy reality in classical electrodynamics in a line of electrodynamics for nondual quantum fields.

By locally pairing energy flows of the radial Newton-Coulomb fields and the densities of the continuous particle, one also unifies in (8) gravi-mechanical and electric self-energies . Such a double unification (particle with field and gravity with electricity) requires one (but complex) charge in the logarithmic potential (7). One can verify quantitatively that the complex (astro)charge distribution, with , generates this strong field potential under the regular integral rule for classical gravitation and electrodynamics,

(9)
(10)
(11)

Notice from the last relation in (9) that coincides with the work associated with replacements of a unit probe charge from the point to against the radial field . The integration over within vanishes identically in (9) in agreement with the physical meaning of potentials for a probe body.

The multibody system of complex charges with strong field electric and gravitational interactions can be described in statics by the ‘long’ logarithmic potential:

(12)

Like in the equality (6), the Yin-Yang Principle universally works for net active and passive densities of overlapping complex charges (or their self-energies) in all field points of the common material space-plenum,

(13)

In spite of paired interactions of elementary extended charges, their volume energy integral demonstrates the system energy conservation law due to interference (dark, invisible) exchanges in the algebra structure of overlapping energy densities,

(14)
(15)

Again, mono-radial densities and can be interpreted under observations as elementary carriers of energy due to measurable radial structures of their Coulomb/Newton fields. It is possible to extract these mono-radial carriers from a visible substance like its parts (radial particles). Based on the experimental data, it can be assumed that only mono-radial elementary carriers can constitute the visible substance. Indeed, bi-radial material densities in the energy integral (12) cannot be in principle retrieved from the visible body together with one particle or one corpuscle. Thus, the interference (invisible, dark) energy densities can be justified for electrodynamics and gravitation only from calculations rather than from experiments and observations. This justification contradicts the motto ‘Nullius in verba’.

Another yin-yang universal law of this Cartesian physics of material fields is the exact compensation of Coulomb/Newton active energies (12) by the self-action of passive charged densities from (11) in their relativistic potential (10):

(16)
(17)

The yin-yang Universe with the mass/charge creation mechanism from ‘the void nothing ’ (i.e. from the net zero energy) stands behind the global integral compensation (13) for active and passive densities of complex energies. The Cartesian world of extended matter is a self-consistent one in energy terms contrary to the Newton empty space with material singularities, Coulomb energy divergence and astronomical black holes.


Maxwell equations are quantitative identities for paired energy flows

The exact analytical solution (3) to Maxwell’s equations rigorously requests the radial astroparticle instead of the conventional point particle (or the smallest material corpuscle assumed by observers in microscopic volumes). However, rigorous solutions demand that the empty space paradigm (presumably resulting from observations and measurements) should be replaced with the non-empty space concept to achieve a coherent theory of classical fields. Distributed elementary energies with smooth densities should stand behind the yin-yang reality, which is available to everyone in observations of regions with high (former particles, substance) and low (weak fields) concentrations of energy.

Like the first pair of Maxwell identities, , the second pair of Maxwell equations for currents can also be considered (in the non-empty space paradigm) as quantitative identities for balanced momentums () of yin-yang paired energy densities,

(18)

Here we used the following identical relations for classical fields:

(19)

Energy-momentum balance of the pair of 4-vector flows in the second identity in (14) requires the absence of energy currents along directions normal to the 4-velocity of the field-energy density (with ). There is no sense in the extra particle notion under the yin-yang scheme of locally paired field densities in Maxwell identities. In other words, the material reality is nothing but inhomogeneous energy flows in all spatial points of the Universe, filled continuously with densities of visible (corporeal) and invisible (incorporeal) matter.

If we consider the electric currents through the coupled field flows of energy in the Maxwell-Lorentz theory for the extended electron, then the variation techniques for paired material fields in unified physics of nonempty space must be different from the textbook variation procedures for the empty space physics of spatially separated particles and fields. Indeed, the current Maxwell equations were derived in the dual action approach to fields and remote particles (which can be varied and fixed independently, like ). In the yin-yang unified approach, self-energy variations of locally paired flows are coupled inseparably and is equal to the sum that doubles the variational result,

(20)
(21)

Thus, the yin-yang Lagrangian for locally paired energies should possess the double electromagnetic density, , of charged material fields,

(22)

compared to the conventional alternative with spatially separated fields and charges. The yin-yang paired variations of (17) with respect to both potentials and currents result in the Maxwell relation or the energy flow identities in (14). It is worth noting that the yin-yang action (17) vanishes for Lagrange variation trajectories:

(23)
(24)
(25)

The integral nullification of charge-energy currents in (18) is in full agreement with the yin-yang compensation law for the case of static matter (13), where the active energy of extended charges is balanced by the passive potential energy due to the self-action in their post Coulomb/Newton radial fields. In other words, the action nullification on the Lagrange trajectory is the expected result for the yin-yang nondual physics. We recall that the conventional current + field action in dual physics, where is instead of in (2), and instead of in (17), does not match such a Lagrange path nullification. This obvious mathematical flaw is the penalty for using an empty space model and for its misinterpretation of continuous material reality. Illogical changes in magnetic fields at fixed currents that locally and identically generate these fields, including any changes of them, have always been one of the unsolved problems of Classical Electrodynamics.


1938 Einstein’s material fields for 1629 Cartesian vortex mechanics

The evolution of Einstein’s theory of relativity has already passed three milestones. They are the first two postulates and the active internal energy of the 1905 Special Relativity, the geometrization of massless metric fields in the 1915 Einstein Equation under the Newton’s empty space dogma, and the 1938 proposition to distribute particle’s mass-energy continuously over all spatial points of the material metric field in the non-Newton nondual approach to physical reality. Recall that the integration of particles into spatial structures of their fields was suggested by Einstein together with Infeld [11] for the further evolution of all physics disciplines: “We would regard matter as being made up of regions of space in which the field is extremely intense… There would be no room in this new physics for both field and matter, for the field would be the only reality.” However, the extended mass has not been yet adopted by modern relativists. Their Newtonian references traditionally associate General Relativity (GR) only with the 1916 empty space metric of Schwarzschild. And they use the Dirac delta-function for the formal presentation of the Lagrange material density in the point mass action for the Newton empty space with material peculiarities along the path . But, the mass density is to be a continuous space-time function in the Cartesian world and the Einstein-Infeld pure field approach to matter [11]. The best mathematical candidate in pseudo-Riemannian geometry to match this scalar physics function is the Ricci scalar density . Indeed, the latter is also unique for a particular distribution of mass-energy in pseudo-Riemannian space-time. By following the Einstein and Infeld propositions of 1938 for nonempty space reality of massive fields, one may request linear proportionality of physics and mathematics scalar densities, . Here again is the universal potential for the inertial/gravitational energy charge and is the dimensionless coupling constant (subject to be defined).

Cartesian vortex dynamics requires to distribute the ‘rest’ mass-energy continuously over all GR 4-volumes in the action integral:

(26)

Therefore, the Cartesian approach to nature reveals the kinematic scalar field next to the inhomogeneous Ricci scalar in the nonempty space-time with inertial densities,

(27)

This inertial field depends on the GR metric tensor , the physical three-velocity and the relativistic speed factor , with . The Hilbert-type variations of (19) with respect to , namely , define the energy tensor density of moving inertial/gravitational fields,

(28)

associated to the covariant material 4-flows, , of continuous masses.

The kinematic field (20) is constant, , for the static case, when , , , and . The latter is the mass-energy tensor of static material densities in the 1938 pure field theory of Einstein and Infeld. Again, in 1915 Hilbert and Einstein considered field densities as massless and, therefore, motionless. They separated the static gravitational field from moving inertial particles by replacing the Ricci tensor construction with the opposite sign to the left-hand side of the 1915 Einstein Equation. Indeed, Hilbert varied the massless Ricci density without any options for its motion in the 1915 field action by formally taking Mathematics is able to study only the coordinate field contribution to the Lagrange dynamical equations in the empty space model of Newton. By following Einstein and Infeld, we admitted the medium-like motion of field matter in (19). And we related the geometrical curvature to inertial mass-energy flows , which are, in fact, metric space-time flows of the material space-plenum.

Cartesian natural philosophy considers the non-stop vortex motion as an origin of matter and its energy. Therefore, the steady vortex auto-organization could be considered as an equilibrium state of the elementary extended mass in the Einstein-Infeld theory of nondual material reality. The geometrical 4-flow of matter provides vanishing spatial transport of mass-energy under the metric equilibrium,

(29)

where , , , , and . There are no stresses within the elementary material space in its dynamical equilibrium and the energy-tensor density (21) is to be traceless in all points of the elementary Cartesian vortex (22),

(30)

The radial auto-organization of the elementary mass-energy within its continuous material space is accompanied by six inherent geometry symmetries [15] (, with , ) under the radial distributions of the continuous mass-energy, , and the time related metric component , . This steady radial distribution of elementary matter is also a stationary solution of the Klein-Gordon type equation (23),

(31)

that here defines the coupling constant as .

The stationary radial solutions of (22) - (24), and for the equilibrium vortex motion, mean that the geometrical Ricci scalar in (24) originates from the inertial field . In other words, the elementary vortex mass has the pure kinematic, Cartesian origin due to for the equilibrium creation of elementary inertial and gravitational energies. The fact that the initial cause of everything lies in mechanical motion was understood by Descartes in the 17th century. Chaotic vortex motions of Ricci metric densities are indeed responsible as for the kinematic creation of the internal mass-energy within the elementary mater-extension of Descartes. It is essential that the vortex self-organization of the inertial (positive) mass-energy is accompanied and balanced by the metric gravitation, , within the same material space. It is clear from the kinematic nature of the Cartesian vortex that the internal mass-energy of elementary matter has the meaning of its internal relativistic heat, associated with chaotic vortex motions of metric densities at high orbital speeds.

Now we look again at the yin-yang compensation (13) of world energies from the Cartesian physics position. From where did the positive (kinetic) rest-mass energy emerge under the vortex auto-organization of the Cartesian matter-extension? The point is that, aside from the equilibrium metric motion for the kinematic creation of inertial mass-energy , the gravitational self-action always arises due to the intense interaction potential [15] of the emerged charge density , with :

(32)

Contrary to measurable exchanges of internal and translation kinetic energies, the negative potential energy is not relevant to observations in practice. But negative energy tensions within the continuous carrier of the elementary relativistic heat is relevant to stability of the elementary extended mass-energy by the internal negative pressure, once assumed by Poincare for the extended particle.


Cartesian references for the Einstein Equation

The internal heat, or an internal kinetic degree of freedom under the spatial transport of elementary energy, cannot be reasonably assigned to the Newton point mass. Therefore, the variable vortex heat is the principle difference between Newton and Cartesian transport of energy, even at the low speed motion of mechanical bodies. Indeed, the Newton point particle possesses only one degree for the summary (internal and translation) kinetic energy, while the Cartesian distributed vortex at rest for the elementary heat-energy possesses both kinetic internal and kinetic translation energies. The Special Relativity kinematic cooling of the elementary rest-mass energy , which is now the elementary relativistic heat, and the pure translation (mechanical) energy reitirate together the Newton-type summary changes of internal (heat) and external (mechanical, translation) kinetic energies, for the low speed () transport of the elementary energy carrier with metric auto-rotations.

The slow spatial motion of the Cartesian mechanical body is first of all the transport of the variable heat integral of vortex densities. The accompanying fraction of the kinetic energy is counted as a small correction of chaos due to the translation ordering. Cartesian transport of two variable energies just formally correspond to the Newton transport of the constant mass plus one variable energy . Newton had no idea about the internal degree of kinematic heat-energy and modeled transport energy changes, , through one summary coefficient . It is clear from Cartesian physics that Newton’s model works properly only for small probe bodies in empty space where internal and external (translation) kinematic degrees of freedom obey the collinear transport laws.

In condensed media, where heat energy gradients and mechanical momentum may have different directions, Cartesian mechanics will not reiterate Newtonian one. Moreover, the Newton model of motionless point masses without internal heat does not coincide with the Cartesian system of static vortices which initially have internal kinetic energy or heat. One can expect some principle differences between the dual and nondual theories of matter for its spatial acceleration and its heat transfer in liquids and gases. Here, different exchange mechanisms can control non-Newtonian energy gains of and thermal losses due to kinematic cooling. Early or later, the elementary relativistic energy of internal vortex motions with variable heat should replace the Newtonian constant mass as a basic notion for description of warm material space in General Relativity. The latter can not rely on Newton’s cold masses in order to incorporate thermodynamics at the low speed limit. Equally, metric gravitation of cold masses cannot considered as a true limit for gravitation of Cartesian energy-charges, which depend on variable heat.

The pure field physics of Einstein and Infeld claims mutual interactions of overlapping mass-energy densities of elementary heat structures, which are forming the indivisible whole called the warm Universe. The world material medium in any considered region is always out of equilibrium, unless the global system has not reached some steady kind of self-organization for local material densities in consideration. The tensor densities (21) for nonequilibrium material flows are balanced in the most general case by external stresses . This general balance for moving nonempty space in nondual physics of Einstein and Infeld corresponds to an analog of the Einstein Equation for formally separated empty space and matter,

(33)

Einstein was the first researcher who tried to derive the motion of particles directly from his gravitational field equation. He was engaged into this conceptual problem for more than 20 years. Empty space regions in Newtonian dual physics are described by field solutions with zero Ricci curvatures, . The motion of point peculiarities in such massless fields can be approximated only through successive iterations [18, 19, 20]. Cartesian physics of material fields is free from these complicated iteration procedures. One can find the exact geodesic equations for any non-equilibrium motion of inertial Ricci densities in the world metric space-time as the vector flow conservation from the general tensor balance (26), . Here it is sufficient to make use of the known geometrical equalities and the Bianch identities 2:

(34)

This general equation of motion can be equally read for the 4-acceleration along a normal axis to the 4-velocity of the scalar mass density ,

(35)

The vector equation (28) for Cartesian mechanics claims that the inertial field contributes to geodesic dynamics of material space densities, while dual theories with the empty space notion are free from such kinematic feedbacks.


Practical benefits from Cartesian physics of Einstein and Infeld

It is very difficult to infer from observations and measurements whether the world space is empty, as Newton modeled for localized bodies and point particles, or this space is filled continuously everywhere with invisible matter, as Aristotle and Descartes claimed. The experimental procedure of a theory verification can reject improper approximations of reality, but cannot select the most correct approach among suitable alternatives [21]. For instance, there are about ten competing formulations of Quantum Mechanics at the moment. General Relativity of 1916 was requested to reiterate Newton’s empty space dogma. But Einstein himself began to share the Cartesian matter-extension for the pure field physics at least since 1938. And non-empty space metric constructions for Einstein’s General Relativity lead again to the same post-Newton findings for the main gravitational tests [16] as the empty-space metric of Schwarzschild can propose. What is the use of reinforcing the Aristotle-Descartes material space if it might not be ever justified in practice?

Recall again that Newton’s low speed dynamics works satisfactorily for small probe bodies where transports of the internal kinetic energy or relativistic heat and the kinetic energy of spatial translations have collinear directions. Newtonian proponents, who have to consider the mechanical motion as a transport of the constant elementary mass , derive dynamical laws for acceleration of such masses and, basing on these laws for constant masses, compute accompanying energy flows. Cartesian physicists have to consider first of all the transport of elementary vortex energies with the kinematic cooling under motion, , and have to derive dynamical laws for vector energy flows. And basing on these dynamical laws for variable elementary energies, they compute accompanying transport of elementary objects with constant masses or fixed rest-energies . These competing force and energy approaches lead to the same low speed dynamics of probe masses in external fields but not of material densities within continuous media with inhomogeneous ‘life forces’ . Streams of liquids and gases are available for measurements and new conceptual tests to distinguish Newton and Cartesian mechanics for reality.

The Cartesian acceleration law (28) for mass-energy flows within the Einstein-Infeld material space can be considered in the limit of vanishing gravitational fields, , and low speeds, , ,
