The macroscopic analogue of a vortex particle is a bubble ring — a toroidal air bubble stabilised by poloidal circulation of the surrounding water. Air bubbles smaller than approximately two centimetres remain spherical; larger bubbles transition to toroidal form as the internal pressure differential punches through the centre (Bonometti & Magnaudet, 2006). This sphere-to-toroid transition is the bubble analogue of the mass gap between monopole and dipole particles: below a critical size, surface tension holds the vortex spherical; above it, the circulation opens an eye. Bubble rings in water also offer the best available visualisation of particle decay: they form, rearrange, split into smaller rings, and transform between toroidal and spherical shapes — not a perfect analogy, but the easiest way to see how vortex structures break apart.
5.1. The Electron and Positron as Wound Orientational Defects
The electron is identified as a wound defect of the lattice’s orientational field; the positron is the same structure wound the opposite way. The lattice’s minimum-energy state has every hyphon’s spin axis on one of the four tetrahedral directions (
Section 2.1). An orientational defect is a localized region where the axes are tilted away from this alignment — not arbitrarily, but wound: following the tilt pattern around the defect’s core, the axes complete one full turn. A single tilted hyphon is not a candidate: the surrounding tension simply restores it, and a tilt angle is continuous — it comes in no natural unit. A wound structure is different in kind: it cannot be untwisted locally, because removing it would require unwinding the entire surrounding pattern at once, and the number of turns is an integer by geometry — +1 or −1, nothing between. The tilt angles are continuous; the winding is quantized. This is where the exactness of charge originates: every electron is identical because every winding of the same sign is the same object. Which sign corresponds to which particle is a convention not fixed here.
Winding is conserved: the total winding of the lattice cannot change smoothly, so a +1 can only appear together with a −1 — pair production is forced by the geometry, not assumed. Annihilation is the reverse: the two windings mesh and cancel, the texture smooths out, and the stored orientational energy leaves as waves of the orientational field — which in this model is light (
Section 3). The pair annihilates into photons by sector identity, with no added rule; and the same identity explains the electron’s ready emission and absorption of light — they are exchanges within a single field.
An orientational defect travels without transporting material: no hyphon changes its position; the pattern of tilts glides from element to element. This is “the particle is the pattern” in its cleanest form. In real quantum crystals, point defects were predicted (Andreev & Lifshitz, 1969) and subsequently observed to move through the crystal as delocalized waves — the measured quantum diffusion of defects in solid helium — so defect-as-wave is laboratory fact in this material class, not merely simulation. One honesty note fixes the epistemic status: the substrate’s quantum character is an input of this framework, its origin an open question (
Section 3); what the identification buys is not a derivation of quantum mechanics but a unification — the electron’s wave nature, its pair production, and its annihilation cease to be separate postulates and become generic behaviour of defects in such a medium.
Charge, on this identification, is not something the electron carries but something the electron is: a wound pattern of the lattice’s own axes, its two senses being the two particles. The sectors of the two long-range forces separate cleanly: the defect’s energy contributes to the pressure field like any energy — that is gravity (
Section 4) — while its charge lives entirely in the winding.
5.1.1. The Sign Law and the Range Question
The interaction follows from superposition. Where two defects’ tilt fields overlap, the elastic energy goes as the square of the total tilt; the cross-term carries the sign. Two windings of the same sense reinforce — the same springs are stressed doubly, the cross-term is positive, and the pair repels. Opposite windings mesh — the fields partially cancel, the cross-term is negative, the material relaxes further the closer they approach, and the descent completes at contact: annihilation is the endpoint of the attraction. Like repels, opposite attracts, from one mechanism.
What is not automatic is the range. A wound texture in a plain, uniformly aligned medium does not produce a 1/r potential; its energetics are confining. Converting the winding into a Coulomb-law charge is the job of the background structure this lattice specifically supplies — the standing tension of the bond network, the four-axis cubic order, and the pressure-dependence of the hyphon size. That such a conversion is physically possible is a measured fact of at least one real material: in spin ice, ± point defects of an ordered lattice demonstrably interact through a genuine Coulomb law, with a measured elementary charge and measurable defect currents (Castelnovo et al., 2008; Bramwell et al., 2009); and wound point textures of an orientational field have been created and imaged in spinor condensates (Ray et al., 2014, 2015). These establish the class, not this lattice. The 1/r far field itself is not in doubt: harmonic relaxation in three dimensions obeys Laplace’s equation, whose point-source solution is 1/r — the same mathematics for gravity’s pressure deficit and charge’s orientational relaxation. The lattice-relaxation calculation posed in
Section 4, extended to the orientational field, supplies what remains: the coefficients — the strengths of both far fields — and the lattice’s exact isotropy. It has not yet been carried out.
5.1.2. Auxiliary Pictures: the Missing Element and the Crowdion
Two earlier candidates are retired as identifications but kept in working roles. The first is the missing-element/extra-element pair — one partial void, and one element with no room for it (the Frenkel pair of crystal physics). This is the recommended simplified mental image, adequate for most everyday reasoning: it gets the essentials right — two opposite disturbances, necessarily born together, attracting as the material relaxes between them, and vanishing completely when they merge. It falls short of the identification in two respects. The count is quantized — one element is missing or it is not — but the two members are not mirror images: a missing and an extra element are structurally different objects with generically different energies, which would leave the electron and positron unequal in mass, whereas opposite windings are the same object mirrored, degenerate exactly — as the pair is measured to be. And nothing ties the pair to light: its recombination energy has no reason to leave as orientational waves, where for the winding pair that outcome is an identity. The second is the crowdion — an extra element delocalized along a close-packed row — which supplied this work’s original intuition and its dynamical picture; its propagation is established by molecular-dynamics simulation in FCC metals (Shepelev et al., 2023), direct experiment being impractical for so mobile a defect, and its Peierls–Nabarro velocity quantization remains the guide for a free defect’s preferred translation speeds (
Section 3.2). As an identification it fails the same two tests and is retained only as the motivating analogue. The soliton electron has a long history (Ekholdt, 2009), following de Broglie’s programme; what is proposed here is the concrete lattice, the explicit question of which defect class fits, and a decision.
5.1.3. Spin, Standing and Travelling
Spin is native to this identification: the defect is made of orientation, so it possesses an axis and two senses without further construction. What spin-½ additionally requires is the half-turn property — a rotation by 360° must carry the state to its negative, restoring it only after 720°. Whether the wound texture of this four-sublattice lattice carries that character is a single open condition — the same Z
2 condition on which
Section 5.5’s neutrino identification rests. One condition underwrites both purchases.
The distinction between charge and neutrality is the distinction between standing and travelling. The electron’s winding is pinned: its tilt field has a fixed sign and a non-zero mean, and a non-zero mean is a permanent charge. The neutrino (
Section 5.5) is a travelling oscillation of the same sector: its tilts alternate and average to zero over every cycle, and a zero mean is no charge at all. A neutral spin-½ object must therefore be a wave, and a charged one must be a standing defect — neutrality and wave-nature are one fact, not two.
5.1.4. Electron Mass
The electron mass is an open quantity of this identification. It is the core-plus-gradient energy of the wound texture, and it has not been computed. That the defect should be light compared with the proton — a texture against a full vortex — is plausible but not derived. The retired crowdion picture offered a kink-mass estimate, m/m_element = 2/(π
2√g) (Braun & Kivshar, 1998; Girifalco & Weizer, 1959); it does not transfer to the orientational identification and is recorded only for completeness. The charge mechanism and its consequences are developed in
Section 7.
5.2. The Proton
The proton is a coherent vortex excitation in the hyphon lattice carrying a single positron. The vortex is a self-sustaining circulation pattern, possibly toroidal in shape; the precise geometry is not pinned down in this version. Different particles correspond to different vortex topologies — not just different sizes — but the specific topology of each particle is not developed in this version.
The proton mass (938.3 MeV) is excitation energy — the energy cost of maintaining the vortex pattern above the lattice ground state. This is confirmed by π0 decay, where 100% of the 135 MeV pion rest mass radiates as photons: only the stored excitation energy is released. As the vortex pattern translates through the lattice, the lattice flow that constitutes the vortex shifts coherently with it. (An alternative phonon-like description, in which the underlying lattice elements remain essentially in place and only the pattern translates — like a magnon in a magnetic crystal — is also conceivable; which picture is the correct one depends on details of the supersolid hyphon medium that are not pinned down here.)
When a vortex resolves, the lattice locally rearranges back toward its ground-state pattern. The rearrangement can leave behind wound-defect pairs of opposite winding: electron–positron pairs. They appear as pairs because total winding is conserved — a single winding cannot be created in isolation (
Section 5.1). The vortex flow then sorts the pair by chirality: the co-chiral member is drawn into the core and becomes the positron that provides the charge; the counter-chiral member is excluded from the core and settles into a much wider orbit — a natural candidate for the atom-scale electron partner discussed in §5.2.1 — escaping entirely only if it remains unbound.
The proton’s charge (+1e) is carried by a single positron, most likely confined inside the vortex core. The antiproton is the same structure with opposite-chirality circulation. This assignment carries a 1021-precision fact for free: bulk-matter neutrality experiments show |q_p| = |q_e| to about one part in 1021, and here the equality is an identity — the proton’s charge is an electron’s charge mirrored, the same wound defect, not a separately generated quantity that happens to cancel. Charge quantization follows from the same construction: one defect, one unit, no free fractions. And the construction forbids something: a neutral particle of the electron’s mass cannot exist, because an electron minus its winding is nothing — none has been observed.
A natural question is why the neutron’s positron and electron, held at sub-femtometre separation, do not annihilate. The answer is in
Section 5.1.1: annihilation is the endpoint of the attraction, completed only at contact, where the two windings mesh and cancel. In the neutron, contact never occurs — the vortex flow holds the two defects in fixed, separated positions on a common axis, and the neutron’s own measured charge structure shows exactly this geometry: a positive interior and a negative exterior, the two-dipole charge model of
Section 5.3 placing the positron in the core and the electron in an outer shell at roughly twice the core radius. They are close, but they do not meet. The same resolution applies at atom scale: the hydrogen electron’s s-state density at the origin is an atom-scale statistical description of the standing wave, not the presence of the wound defect in the proton’s core — the defect does not pass through the core. Electron capture agrees: when an electron is driven onto a proton (p + e
− → n + ν in proton-rich nuclei), the measured outcome is always a neutron — the electron takes up the outer position — and never two annihilation photons.
The magnetic moment supports the same geometry. If the defect’s moment is a circulation property, μ = evr/2 — a current loop, as for orbital moments in standard atomic and nuclear physics — then the free electron, its charge pattern circulating at the Compton radius at c, gives exactly the Bohr magneton. The same defect confined in the proton’s core at r ≈ 0.1 fm gives μ ≈ 0.5 μ_N: the nuclear-magneton scale is not a separate anomaly but the same moment reduced by the confinement radius, the ratio being ~1/1836 automatically. The measured μ_p = +2.793 μ_N sits at this scale; the remaining factor of ~5.6 is shared among the vortex’s own circulation moment, the effective radius, and the circulation speed — which in a tight orbit is not capped at c (
Section 5.6) — and is open.
What makes the proton specifically stable when most vortex configurations decay is an open question. The η′ meson (958 MeV, spin 0) is heavier than the proton but decays in 10−21 s, so mass alone does not guarantee stability. Vortex topology and internal structure determine which configurations are stable; identifying the specific stabilising mechanism for the proton is left to future work.
A body of short-distance scattering data must eventually be answered. Within the standard framework, electron–proton and neutrino–proton deep-inelastic scattering and the stepwise hadron-production ratio in e+e− collisions are organized with striking economy by fractional constituent charges. This model does not contradict the raw measurements, and the standard extraction does not carry over to it: the electron near the core also feels the flow force, not the charge sector alone; the bound positron is in rapid circulation, not static; the neutrino’s role as a charge-blind reference beam is itself open here — as an oscillating tilt wave its charge averages to zero, but whether it vanishes instant by instant, as a short-distance probe would require, is undetermined; and no weak interaction in the standard form fixes the neutrino’s coupling. Replacing the assumptions removes the contradiction, but at the price of a debt: the model owes its own computed account of these cross-sections, and none exists yet. The fractional-charge organization of the data is the benchmark such an account must meet. Recorded as the largest unmet computational front of the charge picture.
The following subsections develop the quantitative picture. §5.2.1 establishes the parallel with hydrogen 1s electron distributions: both have the same exponential form, with characteristic length scales separated by ~2.5×105. §5.2.2 fits the proton’s measured form factor with this exponential baseline plus a small additional shift, comparing several positive-definite candidates against the polarization data.
5.2.1. The Atom-Scale Parallel
The starting point for the proton picture developed here is a mathematical observation about two measured charge distributions at wildly different scales.
At the atomic scale, the hydrogen 1s electron probability density has the form |ψ1ₛ(r)|2 ∝ exp(−2r/a0) = exp(−r/(a0/2)), where a0 = ℏ/(m_e c α) ≈ 0.529 Å is the Bohr radius. The distribution is a simple exponential in r, peaked at the origin, with characteristic falloff length d_atom = a0/2 ≈ 0.265 Å — the natural structural length at atom scale.
At the sub-femtometre scale inside the proton, the measured electric form factor G_E^p(Q2) has the classical dipole shape 1/(1+Q2/Λ2)2, where Λ ≈ 4.27 fm−1. The inverse Fourier transform of this form factor in real space is again a pure exponential, ρ_proton(r) ∝ exp(−Λr) = exp(−r/(1/Λ)), peaked at the origin with characteristic falloff length 1/Λ ≈ 0.234 fm.
These are the same function. Both are exp(−r/ℓ) with a single length scale ℓ. The atomic structural spacing d_atom = a0/2 stands to atom-scale physics as the hyphon spacing d = ƛ_p/2 stands to nucleon-scale physics — in both cases, half of a deeper wavelength (the Bohr radius a0 at atom scale, the proton’s reduced Compton wavelength ƛ_p = ℏ/(m_p c) at proton scale). The two structural lengths differ by a factor d_atom/d = a0/ƛ_p = m_p/(m_e α) ≈ 2.5 × 105, consistent with §2’s two-wavelength organization of matter.
A note on what the parallel does and does not claim. The shared exponential does not mean the same binding force acts at both scales — the forces are entirely different. The electron is held in its sphere by Coulomb attraction to the positron inside the proton; the positron is held in its sphere by the core vortex’s own flow dynamics. What is the same is the class of situation: a point defect confined to a spherical region by a host structure, with a probability distribution rather than a trajectory. The exponential is the signature of that class, indifferent to what does the confining. This is also why the two length scales follow different recipes — a0 = ƛₑ/α carries the Coulomb coupling because Coulomb attraction is the binder at atom scale, while the proton’s falloff sits at ≈ ƛ_p with no factor of α, because the vortex flow, not charge, is the binder at core scale. Different binders, different lengths, one distribution family.
The functional identity is structurally suggestive. The hydrogen electron’s exponential distribution is a standard quantum-mechanical result — the 1s wavefunction solves the Coulomb-potential Schrödinger equation, and the probability density is its square. The proton’s exponential charge distribution, internal to the proton, has no such standard derivation in the quark-model picture; the dipole form factor has been noted for decades as a feature requiring an exponential underlying constituent distribution (Strobel, 1996), but the mechanism remains open in the Standard Model.
In the lattice framework, the parallel has a direct interpretation. The proton is a toroidal vortex in the hyphon lattice. A bound positron — the same wound defect as the free positron — is bound inside this vortex by the flow geometry. Its spatial distribution is set by the same kind of balance that sets the electron’s distribution inside the hydrogen atom: kinetic energy of the charge carrier against the binding geometry of the host. Both give exponential distributions because both are bound states of a point-like charge carrier in a host binding structure — a Coulomb potential in the atomic case, a toroidal hyphon vortex in the proton case.
The two distributions may share more than a functional form. As mentioned in §2, vorticity conservation in a coherent medium typically requires every vortex to have a counter-rotating partner — and there is a natural candidate at the right scale: the bound electron in a hydrogen atom, occupying the atom-scale region around the proton. Whether the proton-scale vortex and the atom-scale electron orbital are linked as a single coupled structure remains a possibility worth exploring in future work.
This parallel motivates the quantitative form-factor fit developed in §5.2.2. The proton’s exponential charge distribution provides the baseline; an additional small shift on top — modelled as a positive-definite function of qR — captures the deviation from pure dipole scaling that polarization data shows at high Q2.
5.2.2. Charge Form Factor
The proton’s electric form factor has been measured for four decades by polarization-transfer experiments, most recently in the final GEp-III reanalysis (Puckett et al., 2017). The data are traditionally summarised by the “dipole scaling” hypothesis: both G_E^p(Q2) and G_M^p(Q2)/μ_p are well approximated at low Q2 by the same standard dipole G_D(Q2) = 1 / (1 + Q2/0.71 GeV2)2, which would imply that the measured ratio R(Q2) = μ_p G_E^p / G_M^p equals 1 identically at all Q2. Polarization-transfer experiments beginning with Jones et al. (2000) showed this dipole scaling to be wrong at high Q2: R drops progressively as Q2 increases, reaching R = 0.448 ± 0.060 at Q2 = 5.17 GeV2, R = 0.348 ± 0.106 at Q2 = 6.70 GeV2, and R = 0.145 ± 0.177 at Q2 = 8.49 GeV2 (Puckett et al. 2017, Table X). At the highest-Q2 point the dipole scaling prediction overshoots the measurement by a factor of nearly seven. No current QCD-based framework (vector-meson dominance, constituent quark, Dyson-Schwinger, lattice QCD) reproduces these high-Q2 values cleanly despite typically using dozens of free parameters.
Several positive-definite shift functions f(qR) on top of the dipole baseline were tested:
where |q|
2 = Q
2(1 + Q
2/(4m_p
2)) is the three-momentum transfer squared in the proton’s rest frame (the relativistic factor reaches 2.4 at Q
2 = 8.5 GeV
2 and is essential at high Q
2). We require f to remain positive at all Q
2 because no measurement of G_E^p has shown it going negative; a function that crosses zero would predict an unobserved feature in the data. Each candidate was fit to the 69 polarization data points using a min-max criterion (minimising the worst-case |residual|/σ rather than the average). The results are summarised below:

Five of the six candidates cluster around two natural V13 length scales: R ≈ 0.105 fm for the displacement and 1/Λ ≈ 0.21 fm for the dipole’s characteristic size. The exponential breaks out of this cluster with a smaller R and a slightly larger Λ; the Yukawa absorbs most of the dipole into its own falling form. The j0 and damped sinc, while fitting the data well within the measured Q2 range, both produce a small negative G_E^p at Q2 beyond current measurements — a behaviour that has not been observed and would require justification.
We adopt the Gaussian shift as the V13 description of the proton charge distribution:
with R ≈ 0.11 fm and 1/Λ ≈ 0.21 fm. R ≈ 0.11 fm is the off-centre shift parameter; 1/Λ ≈ 0.21 fm is the exponential decay rate of the real-space distribution. The radial probability 4πr
2ρ(r) peaks near 0.42 fm and extends to 1.58 fm and beyond. The measured charge radius 0.84 fm is the RMS of this distribution — a statistical summary, not a hard boundary; roughly half the probability sits beyond it. Because elastic scattering resolves only the dense central region where two vortex cores cannot overlap, it measures this core size rather than the full extent of the vortex, which may reach considerably larger scales. The hyphons themselves remain intact lattice elements throughout.
This is the same dipole/exponential form that describes the hydrogen 1s electron at atomic scale, scaled down by ≈ 2.5 × 105.
5.3. The Neutron
The neutron is a proton with an additional bound electron and, pinned with it, the electron’s half-winding partner — a frozen antineutrino twist. The proton is essentially unchanged — same vortex pattern, same positron providing the +1e — and the electron is bound outside the core in its own probability cloud, giving net charge zero. The twist is the travelling helical wave of
Section 5.5 brought to rest: free, its tilt direction rotates and averages out; bound, the rotation stops and the twist is pinned at a specific orientation, which is what gives the neutron’s internal structure its common axis. Like the positron in the proton, the electron has an exponential-like distribution at the lattice scale; the small but non-zero G_E^n signal arises from the slight asymmetry between these two near-mirror clouds.
The pinned twist is not optional decoration; the neutron’s spin requires it. A composite’s spin character follows a strict counting rule: orbital and geometric contributions are always integer, so half-integer total spin requires an odd number of half-winding constituents. A neutron built of proton and electron alone carries two halves — an integer — against the measured spin-½; carried into nuclei, the same count fails for the deuteron, helium-3, and nitrogen-14, the last being the historic 1930 argument that eliminated nuclear-electron models. With the pinned twist each bound electron brings two halves of its own (electron plus twist), and the count becomes the proton number mod 2: half-integer exactly for odd proton number — the measured rule, verified across neutron, deuteron, helium-3, tritium, helium-4, and nitrogen-14. The same bookkeeping forces beta decay’s antineutrino: three halves in, three out — its emission is winding-parity conservation, not a postulate. Measurement constrains which part of the neutrino flips and which is fixed: every neutrino observed has the same handedness, so the half-winding itself is pinned to the propagation, while the tilt phase is what rotates and averages to zero in flight. One honest flag: this rests on the same Z
2 half-winding condition already named open in
Section 5.1.3 — one condition, now underwriting three purchases.
β-decay is the release of this stored configuration. The neutron is heavier than its decay products by 0.782 MeV: the bound state is not deeply bound but metastable — the counter-chiral electron, excluded from the core (
Section 5.2), sits in the shallow outer well holding that energy, and escape requires a lattice fluctuation to carry it over the confining barrier. The 880-second lifetime measures the height of that barrier, not the depth of a binding. At escape the pinned twist unpins and resumes travelling as the antineutrino, sharing the released energy; the proton’s charge is fully exposed and positive charge reappears. Inside a nucleus, neighbouring nucleons reshape the well and the exchange geometry, which is why bound neutrons are stable.
The neutron’s electric form factor follows directly from this picture. Treating both clouds with the same Gaussian-shifted-dipole form used for the proton in §5.2: G_E^n(Q2) = G_E^p(Q2) − G_E^e(Q2), with the proton’s parameters held fixed at their bare-proton values (R_p ≈ 0.115 fm, Λ_p = 4.25 fm−1), and only the electron parameters R_e and Λ_e fitted to the 38 measured G_E^n data points (Q2 = 0.01 to 3.41 GeV2).
The min-max fit gives R_e ≈ 0.21 fm and Λ_e = 3.97 fm−1 (1/Λ_e ≈ 0.25 fm). The model fits all 38 data points within 1.89σ on the worst residual, with χ2/N = 0.96 — comparable to the standard Galster (1.83σ, χ2/N = 0.90) and two-dipole (1.82σ, χ2/N = 0.90) parametrizations on the same data. The model gives ⟨r2⟩_n = −0.126 fm2, within 9% of the measured −0.116 fm2. No model in this comparison stands out as decisively better than the others — they all describe the data within similar precision, which is the same situation Galster has had for forty years. The V13 model is competitive with the standard fits while using a physical interpretation tied to the proton’s bare parameters.

In panel (a) the radius axis is in units of d ≈ 0.105 fm.
The result implies a definite physical picture: the electron in the neutron sits at roughly twice the off-center radius of the bare positron (R_e ≈ 0.206 fm versus R_p ≈ 0.115 fm) and is slightly broader than the positron (1/Λ_e ≈ 0.251 fm versus 1/Λ_p ≈ 0.236 fm, about 7% wider). The bound electron is more delocalized than the positron, consistent with its weaker binding. The Fourier transform of the difference produces the standard “neutron has positive core, negative shell” picture — a positive lobe at small r where the positron’s tighter distribution dominates, and a negative lobe further out where the electron’s wider distribution wins.
The magnetic moment follows the same two-cloud geometry. With circulation moments μ = evr/2 (
Section 5.2), the positron at R_p contributes a small positive moment and the electron at its roughly doubled radius a larger negative one: the neutron’s negative magnetic moment — anomalous for a neutral particle in the naive picture — is automatic here, because the negative charge circulates on the wider orbit. The fitted radii give a net ≈ −0.4 μ_N against the measured −1.913 μ_N: sign and scale from geometry, the remaining factor open to the same knobs as the proton’s (vortex contribution, effective radii, circulation speed).
The same caveats apply as for any modern parametrization of G_E^n: the data are sparse (38 points across 3.4 GeV2 of Q2), some experiments have systematic disagreements, and the extracted electron parameters depend on the proton parameters being correctly fixed. The fit should not be over-interpreted as a definitive statement about the electron’s distribution inside the neutron; it is the closest the simple two-cloud picture comes to the measured form factor with parameters that match the bare proton.
5.4. Mesons and the Baryon-Meson Unification
The pion’s measured electromagnetic form factor F_π(Q2) is well-described by a monopole shape 1/(1 + Q2/Λ2), in contrast to the dipole-like shapes of the proton and neutron. The corresponding real-space charge density is a Yukawa-like exponential, ρ(r) ∝ exp(−Λr)/r, with a normal radial probability 4πr2ρ(r) that peaks at r ≈ 1/Λ and falls off exponentially. In this picture, the pion is simpler than a baryon: a single falling distribution rather than the offset, dipole-shaped distribution that the proton requires. The decay channel π+ → μ+ + ν fits this — the muon has a positron at its centre with no resolvable charge distribution, and the pion sits one step removed from that fully-static configuration.
The decay asymmetries of the pions read naturally in this picture. The π
0 annihilates to two photons in 10
−17 seconds: it is a configuration in which the opposite windings do reach contact — the endpoint of
Section 5.1.1 completing — where the neutron’s geometry holds its pair apart for 880 seconds. The contrast between the two lifetimes is geometry, not a new interaction. The charged pion cannot annihilate completely — a net winding would remain — so it decays instead by reconfiguration, emitting a neutrino as winding parity requires (
Section 5.3), and lives some 10
8 times longer. These readings are consistency observations, not derivations.
One correspondence is already fixed by the measurements: the preamble’s sphere-to-toroid transition maps onto the measured form-factor shapes. The proton’s dipole form factor corresponds to the ring form with an open eye; the pion’s monopole form factor to the simpler closed form with no eye — the measured 1/Q4 versus 1/Q2 fall-offs are the two shapes’ signatures. The detailed vortex topology distinguishing mesons from baryons beyond this correspondence, including how spin assignments emerge from different host geometries, is left for future work.
5.5. The Neutrino
The weak nuclear force does not exist as a separate force in this model. Beta decay and electron capture are the escape from and entry into the bound configuration of
Section 5.3 — threshold physics of the neutron’s outer well, not a new interaction. What remains for this section is the particle those processes emit.
Earlier versions of this model identified the neutrino with the lattice’s longitudinal compression mode. That identification is withdrawn here, because measurement rules it out. In 1958 Goldhaber, Grodzins and Sunyar determined the neutrino’s helicity by measuring the polarization of a photon emitted opposite a neutrino in electron capture on europium-152: the spin is always locked antiparallel to the motion — every neutrino left-handed, every antineutrino right-handed. Fixed handedness is a rotational property, and a compression wave — rotationally symmetric about its direction of travel — has nothing that could carry it. The data decide against the earlier guess, and the correction is made openly.
The neutrino is identified instead as a travelling helical wave of the lattice’s orientational field — the same sector whose standing windings are the electron and positron (
Section 5.1.3). The wave has two distinct aspects, and keeping them separate is what makes the measured properties consistent. The tilt phase rotates as the wave propagates: the local tilt direction, and with it any instantaneous charge-sector amplitude, sweeps around and averages to zero over every cycle — a flipping disturbance with zero mean, which is why the neutrino is neutral and why it is a wave rather than a standing defect: the two facts are one (
Section 5.1.3). The handedness does not rotate: the sense of the helix is a half-integer winding of the same Z
2 character conjectured for the electron’s spin, structurally locked to the propagation — this fixed sense is what helicity experiments measure, and ν and ν̄ are its two values. The same winding is why the neutrino barely interacts: scattering into light or compression would require converting a half-winding into an integer one, which no smooth lattice process can do. Transparency, neutrality, and spin-½ are three faces of one property. Pinned to a fixed orientation inside a neutron, this same wave is the frozen twist of
Section 5.3; unpinned, it flies.
This object has a measured laboratory counterpart: the chiral phonon. Lattice waves that rotate while propagating, with handedness locked to the structure, are now directly observed — truly chiral phonons along the screw axis of α-HgS (Ishito et al., 2023), handedness-split phonon dispersion in quartz (Ueda et al., 2023), and, most relevantly, chiral acoustic phonons in α-quartz obeying pseudo-angular-momentum selection rules (Kim et al., 2026) — acoustic meaning they travel at the crystal’s sound speed, which in this lattice is c. On this identification the neutrino is the space lattice’s chiral acoustic phonon, upgraded from integer to half-integer winding. Everything except the half is observed physics. Two caveats keep the claim honest: measured chiral phonons carry integer winding, so the half remains this model’s addition, resting on the open Z2 condition; and the observed hosts are chiral crystals while this lattice is globally achiral — mitigated by the fact that both senses are needed anyway (ν and ν̄), so the medium must not prefer one.
That a half-winding can exist and survive in a real medium is itself measured: half-quantum vortices — a π orbital winding compensated by a π spin winding — have been observed and are robust in superfluid helium-3 (Autti et al., 2016). And helium-3-A hosts massless, chiral, luminal quasiparticles at its Fermi points (Volovik, 2003) — the established analogue class for a neutrino-like excitation of a condensed medium, with the caveat that its substrate is fermionic where this lattice’s is not.
The neutrino carries no rest mass: it is a wave, travelling at the medium’s wave speed by nature — which is why it moves at, or indistinguishably close to, c. Its speed is no longer conditioned on the longitudinal mode: as a wave of the orientational sector it rides the same channel as light, and the residual condition is only that the two circular senses propagate degenerately at c — the isotropy question of
Section 3.1 in another form. What is detected as a small mass is not stored rest energy: lattice discreteness gives the helical mode a small dispersion correction at finite wavelength, so beta-decay neutrinos propagate slightly below c, and the launch recoil mimics inertia. The supernova SN1987A bound (|v/c − 1| < 10
−9) and the KATRIN limit (m_ν < 0.45 eV) constrain the correction to be small but allow it to be non-zero — consistent with a discrete lattice.
The open conditions are listed explicitly. First, the Z
2 half-winding: whether the four-sublattice orientational order supports it — one condition now underwriting the electron’s spin, the neutrino, and the neutron’s parity count (
Section 5.1.3 and
Section 5.3). Second, the flip bookkeeping: that the rotating tilt phase conserves angular momentum internally in flight is asserted, not derived. Third, whether the instantaneous charge amplitude averages to harmlessness at short probe scales is undetermined (
Section 5.2). Fourth, flavour structure: the three flavours and their mass splittings are unassigned; three helical branches of the four-sublattice structure are a natural direction, not an identification. Fifth, the dispersion law has not been computed quantitatively against oscillation data. Of the identifications in this chapter, this is the one most likely to evolve: it is recorded as the best current understanding, expected to be revisited in future iterations of this work.
5.6. The Lorentz Factor and Rotational Speed
The relativistic energy formula E = γmc2, where γ = 1/√(1 − v2/c2), was derived by Hendrik Lorentz between 1892 and 1904 from the mechanics of objects moving through a stationary ether, before Einstein reinterpreted the same equations without reference to a medium.
In the vortex model, γ describes the energy cost of pushing a vortex through the ether lattice at translational speed v. As a vortex approaches c, the hyphons ahead have less and less time to move aside—the displacement signal travels at c, barely ahead of the vortex. At v = c the signal cannot propagate ahead at all, an infinite column of hyphons must be displaced simultaneously, and the energy diverges.
This is strictly a translational phenomenon. A spinning vortex does not push a column of lattice ahead—it rotates in place. Its neighbours feel the mismatch, but there is no infinite-column problem. Rotational speed has no theoretical ceiling. A vortex can spin at any rate. It cannot do so stably—the lattice bleeds energy from the over-spun vortex—but the instability is energetic, not kinematic. There is no rotational equivalent of the γ divergence.
The column picture can be made quantitative, and it yields a formula. The relativistic relation E2 = (m0c2)2 + (pc)2 can be rewritten exactly as γ = √(1 + L/d), where L = d·(p/m0c)2. Read mechanically: the inertia of a moving pattern is set by the length L of the hyphon column it must carry, measured in lattice spacings, and that column grows as the square of the momentum. On a straight path L is free to grow without limit, and the divergence of γ at v = c is the infinite-column statement above in algebraic form.
Circular motion bounds the column geometrically: an orbit of radius r cannot coherently recruit more than a length ~κr of forward column, with κ an order-one geometric factor. Writing 1/L_eff = 1/(dβ
2γ
2) + 1/(κr), the effective inertia m_eff = m
0√(1 + L_eff/d) recovers the standard γ exactly as r → ∞, but in tight orbits it turns a knee near m
0√(1 + κr/a), where a is the spacing of the lattice’s own elements. Past that knee the simplified form levels off, and that plateau is where it fails: the dragged column shears against the medium outside it and entrains that in turn, layer by layer. What the speed of light limits is the slip between neighbouring layers, not the speed of the defect against the distant lattice — so a faster orbit is accommodated by entraining more layers rather than by refusing to go faster, and the inertia keeps rising without bound instead of saturating. The consequence for rotation is unchanged and now has a mechanism behind it: circulation faster than c is permitted at finite energy, costing more than circulation at c rather than being forbidden, because the c-limit constrains transport, not rotation. A quantitative, speed-dependent entrainment law is left to future work (
Figure 6). Two consequences follow. At r comparable to the lattice spacing — the bound positron’s orbit in the proton core (
Section 5.2) — the inertia caps near √2 m
0, so core circulation above c costs little. And in any laboratory ring the electron should be fractionally lighter than γm

−5 precision of resonant-depolarization calibration, consistent with every existing measurement while remaining, in principle, a falsifiable departure from special relativity. The rewriting itself is exact; what this model adds is the column interpretation and the geometric cutoff, whose form and constant κ are not derived here. Whether the diverging part of a fast defect’s co-moving field in fact resides in the forward column rather than in a contracting core — as it does for one-dimensional lattice kinks — is a computable property of this lattice, and it decides whether the cutoff operates.
5.7. The Gyroscopic Lattice: Laboratory Realisation and the Reciprocity Constraint
A second laboratory system supports the picture of space as a lattice of spinning elements. Nash et al. (2015) built a “gyroscopic metamaterial”—coupled spinning gyroscopes arranged on a lattice—and showed experimentally that it has a genuine vibrational band structure with a sonic gap, behaving as a rigid, dispersive medium of a kind no gas can imitate. This is a direct realisation of the central assumption of the present model: that a lattice whose elements carry intrinsic spin is a real mechanical medium with its own wave speed and dispersion relation, not merely a fluid.
The same work raises the sharpest objection to a spinning-element vacuum, and points to its answer. Nash et al. found that a lattice of gyroscopes all spinning in the same sense breaks time-reversal symmetry and carries waves preferentially in one direction—its edge modes are chiral and non-reciprocal. They further showed that this symmetry breaking is set by the lattice bond-angle distribution together with the common spin direction. A vacuum built this way would be optically handed, which experiment excludes to very high precision.
The hyphon lattice escapes this because its spins are not aligned. The four FCC sublattices spin along the four tetrahedral axes and pair into two antiparallel groups (
Section 2.1); neighbouring hyphons rotate oppositely, so the net angular momentum and the macroscopic time-reversal bias cancel, while the local torsional stiffness that carries light survives. The gyroscopic metamaterial is therefore both the closest engineered analogue of the model and the experiment that fixes a necessary property of the spin arrangement: the vacuum can be gyroscopic at the element scale only if it is non-chiral in bulk, which the opposite-spin sublattice structure guarantees. This constraint closes a loop with
Section 5.2 and
Section 5.5. The measured physics that would make an aligned lattice handed — spin sense steering waves preferentially — is the same physics class as the chirality-selective force of
Section 5.2: near a single vortex the spin sense does discriminate, binding the co-chiral defect and excluding the counter-chiral one; the sublattice cancellation removes the bias only in the bulk average, not locally. And the achiral bulk is exactly what the neutrino picture requires: with no preferred handedness, the two helical senses of
Section 5.5 propagate as a degenerate pair — ν and ν̄ on equal footing — which is the residual speed condition of that section restated. One measured system, three duties: analogue, constraint, and consistency check.
