Tassos poses four questions about the Earth's interior, then lays out — in list form, as compressed statements of physical and geological fact with their numbers attached — the "cognitive tools" he considers necessary to answer them. Only at the very end does he give the answers.</ins></div></td></tr>

Mainstream geodynamics takes the first: the interior is hot, heat escapes by convection, and gravitational settling plus radiogenic heating supply the energy that drives plate motions. Tassos argues for the second, and his conclusion is stated in a single sentence: the Earth, except for a thin surface layer, is "an electrically unbalanced 'real gas' of particles subject to the exclusion principle." His philosophical premise is declared at the outset — "A knowable material reality with necessities, but also with possibilities and potentialities, exists independent of human thought and action."</ins></div></td></tr>

Irreversibility follows from the opposite conditions — lack of thermal equilibrium, non-conservative forces such as friction, interacting particles as in real gases and fluids, and lack of insulation. Since the Earth is a thermally open system, complete reversibility is impossible; complete conversion of thermal energy into mechanical work cannot occur "unless there is a constant input of thermal energy."</ins></div></td></tr>

Entropy in a crystal is ''S'' = ''k''ln''W'', with ''W'' the number of available lattice arrangements or degrees of freedom. The higher the pressure, the more restricted the mobility of atoms, the fewer the degrees of freedom, and therefore the ''lower'' the entropy. Pressure, not temperature, becomes the organising variable — and increasing order under increasing pressure is what he means by irreversibility that is ''upgrading'' rather than degrading.</ins></div></td></tr>

Thermal energy — the sum of translational, rotational and vibrational energy — is only a very small fraction of electronic energy. Binding energy between atoms is of order electron-volts, while between nucleons it is of order MeV, about 10<sup>6</sup> times greater; iron has the highest nuclear binding energy at 8.8 MeV per nucleon. The gravitational force between a proton and an [[electron]] is about 4×10<sup>−47</sup> N against an electric force of about 9×10<sup>−8</sup> N, some 10<sup>39</sup> times greater — and the electric force, he notes, "is behind friction and other contact forces." Van der Waals forces between dipoles and confining walls are about 10<sup>36</sup> times stronger than gravity and "can move the polar atoms against gravity."</ins></div></td></tr>

Tunnelling through a potential barrier can be achieved by heating to 10<sup>6</sup>–10<sup>9</sup> degrees, or by lowering the barrier with an external electric potential, or by ''narrowing'' it to 10<sup>−8</sup>–10<sup>−9</sup> m through pressure. Fusion of hydrogen nuclei, he states, requires a pressure of order 10<sup>26</sup> Pa; a proton travelling at about 3×10<sup>7</sup> m/s produces shock-wave pressures of order 10<sup>30</sup> Pa, since shock waves form wherever wave sources move faster than the waves they produce and the cone sharpens toward a line as speed rises. He gives the reaction chain 2<sup>2</sup>H + 2p → 2<sup>3</sup>He + 2γ + 11 MeV → <sup>4</sup>He + 2p + γ + 13 MeV, yielding two protons and 24 MeV.</ins></div></td></tr>

The pieces he actually needs are these. Identical bosons congregate in the lowest available energy state, which explains lasers and superfluidity. Pairs of identical fermions can form bosons and behave as one large boson system, which is the microscopic explanation of superconductivity — pairing that occurs "when ion lattices can not vibrate, as a result of low temperature ''and/or high pressure''." The zero spin state, from attraction between antiparallel spins, is a low energy state; the unit spin state, from repulsion between parallel spins, is high. Incompressibility results from repulsive forces between identical fermions, compressibility from attraction between identical bosons.</ins></div></td></tr>

Tensile strength of mantle rock is of order 10<sup>10</sup> Pa against 10<sup>6</sup> Pa for granite at the surface; viscosity ranges from 10<sup>20</sup> to 10<sup>27</sup> poise and relaxation times from 10<sup>9</sup> to 10<sup>15</sup> s. In a Stress Engine Earth the mantle behaves as a plastic-brittle material; in a Heat Engine Earth, as a dilatant-ductile one. Tassos ends the compilation with a pointed asymmetry: seismic velocities, density and pressure with depth are known "with a degree of confidence of 95%", whereas the variation of temperature with depth, below about 10 km, "is not directly known."</ins></div></td></tr>

Expansion, in this picture, follows from matter being generated and de-densified under falling pressure as the interior works its way outward, rather than from any thermal engine.</ins></div></td></tr>

By ending on the observation that the depth profiles of velocity, density and pressure are measured while the temperature profile is not, Tassos identifies a genuine soft spot: the geotherm below the shallow crust is inferred from assumed adiabats, phase-transition depths and models of core composition, not measured, and a great deal of standard geodynamics rests on it. His insistence on comparing energy scales before assigning a driver is also sound practice, and the point that electronic and nuclear energies dwarf thermal energies is correct as stated. The emphasis on pressure as a variable that ''reduces'' entropy is a real and under-used idea, and the observation that superconducting-type pairing can be produced by high pressure as well as by low temperature is legitimate physics. As a reading list with numbers attached, the compilation is useful in itself.</ins></div></td></tr>

This is a list, not an argument. Between the physics tools and the geological tools there is no derivation — no calculation in which the quantum quantities are applied to a specific volume of the Earth to yield a rate of volume increase, a heat budget, or a stress. The conclusion that the Earth is a Stress Engine does not follow from the assembled facts; it is placed after them. Nothing in the paper computes how much expansion the proposed mechanism would produce, over what time, or what would be observed if it were wrong.</ins></div></td></tr>

A field of 10<sup>31</sup> V/m is roughly 10<sup>13</sup> times the Schwinger limit at which the vacuum breaks down into electron–positron pairs; the energy density of such a field alone would exceed the mass-energy of the Earth by an enormous factor. A net charge of 10<sup>53</sup> electrons is about 10<sup>34</sup> coulombs, and the electrostatic self-energy of that charge distributed over a body of Earth's radius exceeds the Earth's gravitational binding energy by tens of orders of magnitude — the planet would disassemble instantly. Similarly, a field of 10<sup>21</sup> tesla is some 10<sup>13</sup> times the strongest magnetar field known and vastly beyond the quantum critical field; it is also inconsistent with the paper's own figure of about 0.5 gauss at the surface, which no plausible geometry can reconcile with 10<sup>21</sup> tesla in the core. These quantities are introduced with the word "assumed", and they are never checked against anything.</ins></div></td></tr>

The ratio of thermal to electronic energy is given as 10<sup>−4</sup> to 10<sup>−5</sup> on one page and as 10<sup>−6</sup> to 10<sup>−2</sup> on another. The geothermal heat loss is quoted as "3×10<sup>13</sup> W per year", but a watt is already a rate. Hydrogen is said to have the lowest nuclear binding energy at 1.1 MeV per nucleon, which is the figure for deuterium; ordinary hydrogen has none. The three-force taxonomy, folding electromagnetism into the weak force, is not a defensible simplification but a category error, since the two have different couplings, ranges and conservation laws.</ins></div></td></tr>

The [[Expanding Earth]] hypothesis stands or falls on whether the Earth's radius has changed measurably, and that is now directly testable: space-geodetic solutions combining VLBI, SLR and GPS constrain any secular change in mean radius to well under a millimetre per year, far below what expansion tectonics requires. The paper predates the best of those results, so this is not a fault of the author, but it does mean that the compilation's central conclusion has since been confronted by a measurement it does not survive. Likewise, the observation that oceanic crust is young and continental crust old is real and important, but it is exactly what subduction predicts; presenting it as evidence for expansion requires an argument that subduction does not occur, which the paper does not attempt.</ins></div></td></tr>

<br />
==Abstract==<br />
<br />
Questions to answer:<br /> * Is the dominant character of processes inside the Earth reversible or irreversible?<br />
* If irreversibility dominates, is it degrading or upgrading?<br />
* If upgrading, is it a result of one major catastrophic event that happened very early in Earth&#8217;s history, or is it an ongoing process and a result of many episodes?<br />
* Is the Earth a Heat Engine (Gravity mechanics) or a Stress Engine(Quantum mechanics)?<br />
