A photon is the smallest piece of light; this page follows one photon, closed into a loop, and derives what the high school page stated.
A closed loop turns one way or the other on the plane the expansion selects; that is its charge. Its size is the count of aligned turns per cycle, an integer; its sign is which way it turns:
Q ∝ ∮dφ = 2πn,  so  q = n·q0,  σ = ±1
(n the count of aligned turns per cycle, one here; σ which way the loop turns; in the textbook’s variables q = σe)
The loop throws off a null gravity wave, a ripple with no net change of space density, and another loop feels it only through its own facing: right facing pushes, ninety degrees is a strict null, opposite facing pulls. Far away the interaction is inverse square with its sign from the two orientations:
Fσ1σ2 / r2,  σi ∈ {+1, −1}
The general case, the transported display area as a 2-form, its conservation, the caustic axis, the 1/r², sources and derivation of the Maxwell limit, is not drawn on the high school page;
derived below (panels 6 to 11).

The small figure is the high school drawing. Each numbered circle is exploded below, and each number is a step of the derivation further down. Panels 1 to 5 are the case drawn: one electron loop, its orientation and count, the plane it faces, the base the mass has set, the null gravity wave as the drawing builds it, and the sign law. Panels 6 to 11 are the general solution: display area transported as a 2-form, the identities it obeys, the caustic axis and the two polarizations, flux conservation and the inverse square, sources and the charge as a closed-surface flux, the sign, and the Maxwell limit. The derivation uses these published documents and nothing else: the Mathematical Bridge (section 4, orientation; the waveform section, the preferred plane) and its Math Appendix (Electromagnetism from Void Transport, and its Source Extension), the Electromagnetism Narrative (what charge is; the plane; sign, size and steps; why it is not gravity), the Electromagnetism Math Walk-Through (the Maxwell set and Coulomb) and Math Appendix (section 9, the sign law), the Particle Mechanics Narrative (section 7, q = n·q₀) and Math Appendix (the closure phase), and the Student Workbook (symbols). Only ratios enter; S₀ is the one scale; ε₀, μ₀ and ke are limit locks, not inputs. Moving sources, magnetism and the Lorentz force are in the same documents (the Walk-Through’s section 2; the Math Appendix’s Transport Circulation from Moving Sources) and are not drawn on this page.

A note on the mathematics. The general solution on this page is written in the language of differential forms on a Lorentzian manifold (a transport 1-form A, its exterior derivative K = dA, the Hodge dual ⋆, Stokes’ theorem), with the preferred axis coming from the same fold-caustic asymptotics (the Airy function, the Maslov index) as the photon and matter pages. The forms language is standard graduate mathematics (Flanders, Differential Forms with Applications to the Physical Sciences, 1963; Frankel, The Geometry of Physics, 3rd ed., 2011) and it is the language in which vacuum electromagnetism is most compactly written; the caustic asymptotics are the province of the small community described on the matter page (Arnold, Gusein-Zade and Varchenko, 1985; Kravtsov and Orlov, 1998). Nothing here needs more than those two bodies of work.

A. The case drawn, step by step (the numbers are the circles in the figure)

1. In this case: the loop, which way it turns, and how many turns

The loop is the electron loop of the matter pages, closed on the plane the expansion selects. The Mathematical Bridge (section 4): “Each loop carries an orientation σ ∈ {+1, −1}, preserved under expansion as specified in A3.” And: “When a void loop closes on the preferred expansion plane, the orientation of its rotation defines a polarity. This polarity is identified with electric charge.” How much charge is a count. The Electromagnetism Narrative (section 3): “Sign: which side of the preferred plane the loop’s orientation locks to. Size: how many aligned turns per cycle the loop contributes (an integer count when you coarse-grain over time). Steps (quantization): you only change the count at discrete orientation-flip or merge/split events; it doesn’t slide continuously when closure holds.” The Particle Mechanics Narrative (section 7): “Stable loops carry integer winding numbers. Those give discrete charge steps and spin classes.”

Δφloop = (1/ħ)·∮p·dl = 2πn,  n ∈ ℤ  (closure; Particle Mechanics Math Appendix)
q = n·q0  (Particle Mechanics Narrative, 7);  σ ∈ {+1, −1}  (Bridge, 4);  shadow: q = σe  (Student Workbook, symbols)

The drawing’s loop makes one turn per cycle, n = 1; the mirror loop is the same loop with σ flipped. Nothing else distinguishes them: same closed route, same obscured volume, same mass (matter page, step 7), opposite sign.

2. In this case: the preferred plane, why there is a facing

The Electromagnetism Narrative (section 2) gives the plane in the same bookkeeping as the matter pages’ split. For fragments of volume Vi that merge into one body the display area contracts by

Fmerge = Aafter/Abefore = (ΣiVi)2/3 / ΣiVi2/3 ≤ 1;   two equal fragments: Fmerge = V2/3/[2(V/2)2/3] = 2−1/3 = 0.7937  (inverse of the split factor 21/3)

“When a loop splits and merges space along its route, splitting expands display-area and merging contracts it. That rule naturally picks out the preferred plane for the loop’s motion from the caustic, on that plane the expansion/merging bookkeeping balances best. ‘Facing’ is judged against that plane. The sign we call ‘positive’ or ‘negative’ is just which direction, counterclockwise vs clockwise locked to that common plane.” The Bridge (Waveform) says how the plane holds a loop: “Expansion-driven caustics select a preferred plane in the surrounding space; loops are steered toward that plane rather than ‘choosing’ it … tilt the loop off the ridge by a small angle θ and the transport pushes it back toward the plane, while reversing the loop’s rotation flips the side toward which the transverse push acts, setting the handed response of the force.” Panel 2 plots Fmerge(a) for two parts a and 1 − a; its minimum at a = ½ is the 2−1/3.

3. In this case: the base, what the mass has already set

The grey of the drawing is not charge; it is the mass. From the mass pages (Mathematical Bridge Math Appendix, Mass and Gravity from Closed Void Loops), seen from outside a loop of radius R₀ = ƛe omits the span it hides, and the share of space missing at radius R is

R = √(r² − R0²),   δ(R) = R0²/(R² + R0²) = R0²/r²;   δ(0) = 1,   δ = ½ at the rim,   δ → R0²/R² far out (inverse square)

Every shade of the base is this δ at that radius: the dark ring at the loop’s edge is δ = ½, the point itself would be δ = 1, and the base fades to white where δ no longer leaves a visible mark. The wave of panel 4 rides on that base and returns to it.

4. In this case: the null gravity wave, as the drawing builds it

The Electromagnetism Narrative (What Is Charge in VMS?): “A ‘charged’ thing here is a rotating void-loop that’s constantly throwing off null-gravity waves (NGWs) ripples. Those ripples don’t pile anything up, no net space-density change. Another loop only feels something if it’s also spinning and its facing lines up with the ripple pattern. The effect is purely orientation-gated.” The drawing shows one such ripple: a white line born at the tail (released space, the same white as no-mass space far away), a band easing back to the base shade, complete at the head’s edge; net change through the band, zero. The drawing gives the band a width by one rule of its own, stated here as such and not as a line in any document: both edges run at c; where a share δ of space is missing, the release edge covers drawn distance faster, and the head edge, crossing space the release edge has already freed, does not:

release edge: dr/du = c/(1 − δ(r));   head edge: dr/du = c,  0.7 rad behind;   band contrast ∝ δ  (drawn eased as √δ, declared)

Integrated from the rim, the gap grows fastest at the rim (δ = ½) and saturates as δ dies; the high school figure prints 1.26 ƛe and 1.40 ƛe at two crossings, and panel 4 recomputes the two edges from the rule. One turn of ribbon per loop period, its handedness the sign: that is the count of panel 1, made visible.

5. In this case: push, null, pull

The Electromagnetism Math Appendix (section 9) writes the facing law as an equation once, for its neutral-rotor test: a spinning body aligned to the caustic plane, with ε the closure/tear bias, σ the spin orientation (+1 right-handed, with +n̂; −1 opposite) and θ the facing angle to +n̂:

⟨Δp⟩ ∝ ε · σ · cos θ  (Eq. 9.4);  right spin + right facing (σ = +1, θ = 0°) → push;  90° tilt → strict null;  spin-flip or opposite facing (σ = −1 or θ = 180°) → pull

That equation is the rotor prediction; for two loops the same push, null, pull is the Narrative’s statement in words, and the two-charge sign law is the Bridge’s F ∝ σ₁σ₂/r² of step 10. The Narrative: “Right spin, right facing → you get a push; wrong facing → the pushes cancel over a cycle and you feel nothing net. opposite facing you get a pull.” And why this is not gravity (section 6): “Gravity behaves like a standing curvature gradient, a downhill. Anything with inertia ‘rolls’ the same way no matter how it’s turned. Electromagnetism here is different: there’s no standing downhill, just a traveling pattern, so the outcome depends completely on how you’re oriented.” Two loops of opposite sign pull together, two of the same sign push apart: the push and pull page.

B. The general solution: charge from transported display area

6. Display area transported: the 2-form K = dA

Now the general case, from the Mathematical Bridge Math Appendix, Electromagnetism from Void Transport (No Field Primitives). The objects: the display area density Ad, “transverse obscuration measured along transport”; a transport 1-form A that “encodes oriented accumulation of Display Area along worldlines/surfaces (no ‘field’ postulate)”; its exterior derivative K := dA, “oriented flux of Display Area (a curvature of transport; again, not a field primitive)”; and the Hodge dual ⋆ from the metric that A1 and A2 fix. For any oriented patch S carried by the front,

∂S A = ∬S K,   K := dA  (Stokes; “No dynamics are assumed here”)
dK = 0  (geometric identity / absence of transport sources),  d⋆K = 0  (conservation of transported obscuration density under expansion, from A2–A3)

“Here A3 (finite tension) is crucial: it enforces that transported flux remains finite, so conservation under expansion leads to an unavoidable 1/r² falloff. Without finite nonzero Ts, flux would dilute improperly or diverge.” (section 3). This is the same finite tension that made a finite G exist on the matter page.

7. The caustic fixes the axis: one normal, two polarizations

Section 2 of the same derivation. Parameterise the Void front by rays x = X(q, t), q ∈ ℝ²; the Jacobian J(q, t) = det(∂X/∂q) measures local area transport, and at J = 0 a fold caustic forms. With canonical coordinates ξ normal and η tangential to the caustic, the transported obscuration admits the uniform Airy form near the fold:

u(ξ, η, t) ≈ 𝒜(η, t) Ai(αξ),  α > 0;   oscillations for ξ < 0, exponential decay for ξ > 0, a π/2 phase across the fold (Maslov index ½)
n̂ = ∇ξ/|∇ξ|  the preferred axis; oscillations transverse to n̂; “Symmetry ensures only two polarizations (±) remain.”

This is the same fold that the photon page’s x³ normal form describes; here it does one more job: it fixes a direction in space, the axis against which “facing” in panels 1, 2 and 5 is measured. Panel 7 plots Ai(αξ), computed.

8. The wave operator, the action, and the inverse square

Sections 4, 5 and 7. Apply d⋆ to K = dA and use d² = 0: d⋆dA = 0. The relabelling freedom A → A + dχ allows ∇·A = 0, and the transport equation becomes the wave equation; the preferred axis enforces transversality. The two identities follow from stationarity of a geometric action, with the same σs as the matter page:

□A = 0,   □K = 0;   n̂·A = 0,   n̂⌟K = 0  (exactly transverse; two independent polarizations)
S[A] = (1/2σs) ∫ K ∧ ⋆K,   δS/δA = 0 ⇒ d⋆K = 0  (dK = 0 is geometric)
𝒥 := (1/σs) ⋆(A ∧ K),   d𝒥 = 0  in vacuumflux through spheres constant: amplitude ∝ 1/r,  intensity ∝ 1/r²

This 1/r² is the intensity of the transported wave, the far field of a radiating source; the static inverse-square force between two charges is a different statement, and comes from the source equation d⋆K = J through Poisson’s equation in step 11. “This derives entirely from expansion and finite tension (A2–A3). Riding the wave outward, one perceives conservation: the further one goes, the wider the ripples spread, and the weaker each crest must be to conserve flux.” And the remark that separates the two far fields: “Magnetism drops off faster than gravity because here the conserved flux is tied to transverse oscillations set by tension. Gravity, by contrast, is encoded in space curvature directly and dilutes differently.” Panel 8 draws the equal flux through nested spheres and the two curves.

9. A source: the charge as a closed-surface flux

The Source Extension (sections 10 to 14). “Sources arise when Void transport fails to close perfectly (broken closures, defects, intersections), creating conserved transport currents.” Introduce a transport current 3-form J, “oriented injection of transported Display Area”; consistency requires dJ = 0. The equations and the action that produces them:

dJ = 0  (continuity);  dK = 0,   d⋆K = J
S[A; J] = (1/2σs) ∫ K ∧ ⋆K + ∫ A ∧ J  ⇒ δS/δA = 0 gives d⋆K = J; A → A + dχ leaves S invariant iff dJ = 0
Q[V] := ∫V J = ∫V d⋆K = ∮∂V ⋆K  (surface independent, by dJ = 0);  □A = 𝒮[J]  (retarded: causal at c; far zone 1/r amplitude, 1/r² intensity)

“Thus Q is measured by the flux of ⋆K through any closed 2-surface surrounding the source.” That is the general statement of what panel 1 counted: the closed loop, a transport that does not close perfectly, is the source, and its strength is the flux through any surface round it, the same for every surface. The integer of panel 1 is the count of that flux in units of the electron loop’s; the Workbook’s q = σe is the shadow of Q for one loop.

10. The sign: the same loop, the second far field

The Mathematical Bridge, section 4, closes the loop back to panel 1: “Relative orientation determines the sign of far-field interaction. The far-field again follows a 1/r² dependence, but its direction depends only on σ. Binary polarity is therefore a direct geometric consequence of orientation.”

F ∝ (σ1σ2) / r²,   σi ∈ {+1, −1}    beside gravity, the matter page’s F = Gmm′/r²  (always toward, no σ)

Same loop, two far fields, both inverse square: one from the volume the loop obscures, always attractive; one from which way it turns, with a sign. The high school drawing is the second one, seen at the loop; panel 10 is its far field. The Bridge Narrative says it in one line: “Mass is missing space; gravity is how another spinning Void responds to that missing space; electromagnetism is orientation on the same stage”.

11. The limit engineers use: Maxwell, and Coulomb

The Electromagnetism Math Walk-Through carries the same two identities into the familiar variables. “Display-area flux is encoded as a 2-form F with dF = 0 (Bianchi). With action S[A] = ½∫F ∧ ⋆F and minimal coupling ∫J·A d⁴x, Euler–Lagrange yields d⋆F = J.” Splitting A = (Φ, A) gives E = −∇Φ − ∂A/∂t and B = ∇×A, and the components are the Maxwell set (Box 1); the static point source gives Coulomb (Box 4):

∇·E = ρ/ε₀,   ∇·B = 0,   ∇×E = −∂B/∂t,   ∇×B = μ₀J + μ₀ε₀ ∂E/∂t;   ∇²E − μ₀ε₀ ∂²E/∂t² = 0,   c = (μ₀ε₀)−1/2
ρ = q δ³(x) ⇒ Φ = keq/r,   F = ke q1q2/r²,   ke = 1/(4πε₀)  (a limit lock, not an input)

“Sources are geometric descriptors: (ρ, J) from orientation and topology of loops.” The Narrative (section 5): “When you average these orientation-gated path nudges over time and over many loops, in smooth, weak-curvature conditions, the effective path law you recover is the same set engineers already use: the standard Maxwell equations.” The Math Appendix names the dictionary in one line (section 8): “If one chooses to adopt conventional names at the end, components of K transverse to n̂ coincide with the usual vacuum electromagnetism quantities, and the pair dK=0, d⋆K=0 matches the standard homogeneous and inhomogeneous vacuum equations.” And its caveat: “This reinterpretation is optional and appears only here for comparison; the proof does not depend on it.” The only dimensional scale admitted is S₀ = ħ; ε₀, μ₀ and ke are acceptance locks.

Mathematical Bridge Math Appendix: Electromagnetism from Void Transport (No Field Primitives), sections 1 to 9 (objects; the caustic axis and Airy form; ∮A = ∬K, dK = 0, d⋆K = 0; □A = 0; S[A] = (1/2σs)∫K∧⋆K; 𝒥 and the 1/r²; naming only at the end); Source Extension, sections 10 to 17 (J, dJ = 0; d⋆K = J; S[A; J]; Q[V] = ∮⋆K; retarded □A = 𝒮[J]); Mass and Gravity from Closed Void Loops (the map and δ, via the mass pages). Electromagnetism Narrative: What Is Charge in VMS?; sections 1 (the surfer), 2 (Fmerge, the preferred plane, the sign as direction), 3 (sign, size, steps), 5 (the Maxwell limit), 6 (how this is not gravity). Electromagnetism Math Walk-Through: section 0 and 1 (F = dA; the Maxwell set, Boxes 1 and 2), section 2 (Lorentz force, Coulomb, Boxes 3 and 4). Electromagnetism Math Appendix: section 9, Eq. 9.1 to 9.5 (ε, σ, θ; ⟨Δp⟩ ∝ ε·σ·cos θ; push / null / pull). Particle Mechanics Narrative: section 7 (integer winding numbers; q = n·q₀). Particle Mechanics Math Appendix: Δφloop = (1/ħ)∮p·dl = 2πn. Electromagnetism Student Workbook: symbols (Q, closure measure from σ; shadow q = σe). Generator: gen_charge_proofs3d.py.
