1. Why G Must Scale Between Similarity Levels
The Dimensional Argument
The gravitational constant $G$ has dimensions:
$$[G] = \frac{L^3}{M \cdot T^2}$$
Between similarity levels, all three constituent dimensions change:
- Length ($L$): Atomic distances are vastly smaller than solar system distances
- Mass ($M$): Nucleon mass is vastly smaller than stellar mass
- Time ($T$): Atomic orbital periods are vastly shorter than planetary orbital periods
Since $G$ is built from length, mass, and time, its numerical value must change when expressed in the natural units of a different similarity level. This is not a physical assumption $-$ it is arithmetic. A quantity with dimensions cannot remain numerically unchanged when all of its constituent dimensions scale.
Analogy
The speed of light has a different numerical value in m/s versus km/hr. The physics doesn't change $-$ the number changes because the units change. The same principle applies to $G$ between similarity levels: the fundamental gravitational coupling may be universal, but its numerical expression in $SL_{-1}$ units differs from its expression in $SL_{0}$ units.
2. The Kepler Constraint
Deriving the Master Relationship
Kepler's Third Law governs orbital dynamics at every similarity level:
$$T^2 = \frac{4\pi^2 r^3}{GM}$$
This can be rearranged as:
$$T^2 \cdot G \cdot M = 4\pi^2 r^3$$
Between $SL_{0}$ (solar system) and $SL_{-1}$ (atomic), each quantity scales as a power of the distance scaling factor $k$:
| Quantity | Scaling | Exponent |
|---|---|---|
| Distance ($r$) | $r_{-1} = r_0 / k$ | $-1$ (by definition) |
| Time ($T$) | $T_{-1} = T_0 / k^a$ | $-a$ |
| Mass ($M$) | $M_{-1} = M_0 / k^b$ | $-b$ |
| Gravitational constant ($G$) | $G_{-1} = G_0 \cdot k^c$ | $c$ |
Substituting into Kepler's law at $SL_{-1}$:
$$(T_0 / k^a)^2 \cdot (G_0 \cdot k^c) \cdot (M_0 / k^b) = 4\pi^2 (r_0 / k)^3$$
$$T_0^2 \cdot k^{-2a} \cdot G_0 \cdot k^c \cdot M_0 \cdot k^{-b} = 4\pi^2 r_0^3 \cdot k^{-3}$$
Since $T_0^2 \cdot G_0 \cdot M_0 = 4\pi^2 r_0^3$ at $SL_{0}$, dividing gives:
$$k^{-2a + c - b} = k^{-3}$$
Therefore:
$$\boxed{c = 2a + b - 3}$$
This is the Kepler constraint $-$ a rigid mathematical relationship between the four scaling exponents. Given any two, the third is determined. There is exactly one degree of freedom once distance scaling ($k$) is fixed.
Implications
- You cannot independently choose all four exponents
- If distance scales as $k$, only two of ($a$, $b$, $c$) are free
- The constraint holds regardless of the physical mechanism (gravitational shadowing, magnetic contributions, or any other force law that produces Keplerian orbits)
3. Scaling Exponents from Observation
Reference Objects
To determine the actual scaling exponents, we compare analogous objects between $SL_{0}$ and $SL_{-1}$:
| Quantity | $SL_{0}$ Reference | $SL_{-1}$ Reference | Source |
|---|---|---|---|
| Distance | Oort radius: $1.165 \times 10^{16}$ m | Bohr radius: $5.29 \times 10^{-11}$ m | Astronomical observation / QM |
| Mass | Sun: $1.99 \times 10^{30}$ kg | Proton: $1.673 \times 10^{-27}$ kg | Measured |
| Time | Earth orbital period: $3.15 \times 10^7$ s | Mercury planetron period: $8.55 \times 10^{-16}$ s | Observed / spectral |
Calculating the Exponents
Distance scaling factor:
$$k = \frac{r_{Oort}}{r_{Bohr}} = \frac{1.165 \times 10^{16}}{5.29 \times 10^{-11}} = 2.20 \times 10^{26}$$
Time scaling exponent ($a$):
$$\frac{T_0}{T_{-1}} = \frac{3.15 \times 10^7}{8.55 \times 10^{-16}} = 3.68 \times 10^{22}$$
$$k^a = 3.68 \times 10^{22} \quad \Rightarrow \quad a = \frac{\log(3.68 \times 10^{22})}{\log(2.20 \times 10^{26})} = \frac{22.57}{26.34} \approx 0.857$$
Mass scaling exponent ($b$):
$$\frac{M_0}{M_{-1}} = \frac{1.99 \times 10^{30}}{1.673 \times 10^{-27}} = 1.19 \times 10^{57}$$
$$k^b = 1.19 \times 10^{57} \quad \Rightarrow \quad b = \frac{\log(1.19 \times 10^{57})}{\log(2.20 \times 10^{26})} = \frac{57.08}{26.34} \approx 2.167$$
G scaling exponent ($c$) from the Kepler constraint:
$$c = 2a + b - 3 = 2(0.857) + 2.167 - 3 = 1.714 + 2.167 - 3 = 0.881$$
Comparison to empirical G ratio:
$$\frac{G_{-1}}{G_0} = \frac{3.81 \times 10^{13}}{6.674 \times 10^{-11}} = 5.71 \times 10^{23}$$
$$k^c = 5.71 \times 10^{23} \quad \Rightarrow \quad c_{empirical} = \frac{\log(5.71 \times 10^{23})}{\log(2.20 \times 10^{26})} = \frac{23.76}{26.34} \approx 0.902$$
The Kepler constraint predicts $c \approx 0.88$; the empirical value gives $c \approx 0.90$. The close agreement (within the uncertainty of reference object selection) confirms the framework is internally consistent.
4. The Complete Scaling Framework
Scaling Laws Between Similarity Levels
For the distance scaling factor $k$ between $SL_{0}$ and $SL_{-1}$:
| Quantity | Scaling | Approximate Exponent | Exact Value |
|---|---|---|---|
| Distance | $r_{-1} = r_0 / k$ | 1 (definition) | $k \approx 10^{25}$ to $10^{26}$ |
| Time | $T_{-1} = T_0 / k^a$ | $a \approx 0.86$ | From orbital period ratios |
| Mass | $M_{-1} = M_0 / k^b$ | $b \approx 2.17$ | From Sun/proton mass ratio |
| Gravitational constant | $G_{-1} = G_0 \cdot k^c$ | $c \approx 0.88$ | From Kepler constraint |
Constraint: $c = 2a + b - 3$ (always satisfied)
Why the Exponents Are Not Simple Fractions
Unlike the idealized case ($k$, $k^{3/2}$, $k^3$), the actual exponents are not simple integer fractions. This reflects the physical reality that:
- Nucleons are settled objects $-$ iron star analogs, not main-sequence star analogs. Their mass-to-size ratio differs from active stellar systems.
- Magnetic forces contribute at $SL_{-1}$ $-$ planetron orbits are governed by gravity plus magnetic interactions, not gravity alone. This modifies the effective mass-distance-time relationships.
- Reference objects are imperfect analogs $-$ the Sun and proton are not exact self-similar counterparts (the Sun is mid-evolution; nucleons are fully settled).
The Kepler constraint ensures internal consistency regardless of these complications.
5. Physical Interpretation
What G Scaling Means Mechanically
There are two complementary ways to understand G scaling in the AAM framework:
Interpretation A: Dimensional Bookkeeping
$G$ is a conversion factor between units of length, mass, and time in gravitational dynamics. Between similarity levels, all three base dimensions change. The numerical value of $G$ changes accordingly $-$ not because the underlying physics changes, but because the "ruler," "clock," and "scale" are all different.
This is analogous to how the speed of light has different numerical values in different unit systems, while the physics remains identical.
Interpretation B: Effective Gravitational Coupling (Preferred)
The fundamental gravitational shadowing mechanism (Axiom 1) is universal and scale-invariant. However, at $SL_{-1}$, the effective orbital dynamics include contributions beyond pure gravitational shadowing:
- Nucleon magnetic dipoles $-$ nucleons are settled iron stars with strong magnetic fields from their internal rotation. This creates dipole interactions with orbiting planetrons.
- Magnetic force geometry $-$ for co-rotating bodies in the equatorial plane (the typical planetron configuration), the magnetic dipole interaction is repulsive (parallel dipoles side-by-side repel). This partially opposes gravitational attraction.
- Net effect $-$ the combination of gravitational attraction and magnetic repulsion produces orbital dynamics that differ quantitatively from pure Keplerian gravity. When fit to a Keplerian model, this appears as a modified $G$.
The key insight: The "scaling" of $G$ does not require the fundamental gravitational coupling to change. It can emerge from the additional magnetic forces present at $SL_{-1}$ due to the settled, iron-rich, magnetically active nature of nucleons.
This interpretation preserves the principle that fundamental laws are scale-invariant while acknowledging that the effective dynamics at each similarity level include scale-dependent contributions (magnetic properties, density, composition).
Comparison: Nucleon Pairs vs Planetrons
| Configuration | Magnetic Interaction | Combined Effect |
|---|---|---|
| Nucleon binary pairs (co-rotating, equatorial plane) | Repulsive | Gravity + magnetic repulsion \(\rightarrow\) stable locked mutual orbit |
| Planetrons orbiting nucleus (co-rotating, equatorial plane) | Repulsive | Gravity must overcome magnetic repulsion \(\rightarrow\) effective $G$ appears larger |
In both cases, the magnetic repulsion between co-rotating bodies in the equatorial plane contributes to the force balance. For nucleon pairs, this creates the stable "hand-mixer" configuration. For planetrons, it means gravity must be stronger than a naive Keplerian calculation would suggest, which manifests as an apparently enhanced $G_{-1}$.
6. Magnetic Contributions at $SL_{-1}$
Why Magnetic Forces Matter More at Atomic Scale
At $SL_{0}$ (solar system), planetary magnetic moments are negligible compared to gravitational forces $-$ the Sun's gravitational pull dominates orbital dynamics entirely.
At $SL_{-1}$, the situation differs fundamentally:
- Nucleons are iron stars $-$ fully settled, iron-rich composition with aligned internal magnetic domains
- Rotation is rapid $-$ nucleon rotation at THz frequencies produces strong magnetic dipoles
- Distances are tiny $-$ magnetic dipole force scales as $r^{-4}$, falling off much faster than gravity ($r^{-2}$), but at fm-scale separations the magnetic force is significant
Dipole Field at the Equatorial Plane
For a magnetic dipole with moment $\vec{m}$ oriented along the rotation axis, the field at the equatorial plane (where planetrons orbit) is:
$$\vec{B}_{equator} = -\frac{\mu_0}{4\pi} \frac{\vec{m}}{r^3}$$
The field points opposite to the dipole moment at the equator. A co-rotating planetron with its own dipole aligned in the same direction experiences an anti-aligned local field $-$ resulting in repulsive interaction.
Force Decomposition
The total radial force on a planetron:
$$F_{total} = F_{gravity} - F_{magnetic,repulsive}$$
$$F_{total} = \frac{G_0 M_{nucleus} m_{planetron}}{r^2} - f_{mag}(r)$$
where $f_{mag}(r) \propto r^{-4}$ for dipole interactions.
For the orbit to match observed frequencies, $F_{total}$ must equal the centripetal requirement. When we fit this to a pure Keplerian model (attributing everything to gravity), the effective gravitational constant becomes:
$$G_{eff} = G_0 + \Delta G_{magnetic}(r)$$
The distance-dependent magnetic correction $\Delta G_{magnetic}$ means that $G_{eff}$ is not truly constant even within a single similarity level $-$ it varies with orbital radius. This may explain why different planetrons (at different radii) show slightly different effective $G$ values, and why the overall "average" $G_{-1}$ differs from $G_0$.
Open Question
The precise decomposition of $G_{-1}$ into gravitational and magnetic contributions requires:
- Knowledge of the nucleon's magnetic dipole moment at $SL_{-1}$
- The planetron magnetic moments (expected to be negligible due to tidal locking)
- A force-balance calculation at each planetron's orbital radius
This decomposition is a priority for future work and would provide independent validation of $G_{-1}$ from first principles rather than empirical fitting.
7. Consistency with Validated Work
Validation Audit
All validated AAM results use empirically determined $G_{-1}$, anchored to observed spectral data. None depend on ideal geometric scaling alone.
| Validation | $G_{-1}$ Used | Empirical Anchors | Error | Status |
|---|---|---|---|---|
| 2.1.1 Hydrogen spectral lines | $3.81 \times 10^{13}$ | NIST spectral frequencies | $<0.4\%$ | Complete |
| 2.1.4 Planetary resonance | Implicit (ratios) | Solar/atomic orbital ratios | $p < 10^{-20}$ | Complete |
| 2.1.5 Hydrogen N-body | $3.81 \times 10^{13}$ | Validated orbital radii | $0.00\%$ drift | Complete |
| 2.2.2 Helium spectral | $3.81 \times 10^{13}$ | NIST spectral frequencies | $3\%$ avg | Complete |
| 2.2.3 He-4 nuclear structure | $3.81 \times 10^{13}$ | Charge radius measurement | $1.8\%$ | Complete |
| 2.2.5 Helium ionization | $3.81 \times 10^{13}$ | Measured ionization energies | $0.08\%$ avg | Complete |
| 2.2.2 Singlet-triplet | Observed frequencies | 9.26 THz outer orbit | $1.0\%$ | Complete |
Key finding: The validated scaling framework (January 2026) derives $G_{-1} = 3.81 \times 10^{13}$ from the magnetic boundary interpretation of the proton radius ($k_r = 5.5 \times 10^{25}$), validated by $<0.4\%$ match to all 8 hydrogen planetron orbital frequencies. This empirical determination is consistent with the Kepler constraint and does not depend on any particular theoretical derivation of the scaling exponent.
8. Summary
Core Results
- G must scale between similarity levels $-$ dimensional necessity from $[G] = L^3 M^{-1} T^{-2}$
- The Kepler constraint $c = 2a + b - 3$ rigidly connects the scaling exponents of distance, time, mass, and $G$
- Observed exponents from empirical data: $a \approx 0.86$ (time), $b \approx 2.17$ (mass), $c \approx 0.88$ ($G$) $-$ all satisfy the Kepler constraint
- Physical interpretation: The fundamental gravitational coupling is scale-invariant. The apparent scaling of $G$ reflects (a) dimensional unit changes between SLs, and (b) magnetic force contributions at $SL_{-1}$ from settled iron-star nucleons.
- Validated work is consistent $-$ all spectral, ionization, and stability validations use empirically anchored $G_{-1}$ values that satisfy the Kepler constraint.
What This Establishes
- The scaling laws between similarity levels are constrained but not rigid $-$ one degree of freedom exists within the Kepler constraint
- The exponents are determined by observation, not by geometric idealization
- The framework is internally consistent: Kepler's law, dimensional analysis, and empirical measurements all agree
- Future first-principles work on the gravitational-magnetic force decomposition can independently verify $G_{-1}$
