This supplement bridges the static topological structure of S1-S2 to physical dynamics. It explores torsional geodesic flow, discusses the scale bridge from Planck to electroweak scales, and presents cosmological predictions.
Date: December 2025
The GIFT framework’s dimensionless predictions (S2) require dynamical completion to connect with absolute physical scales. Joyce’s theorem guarantees a torsion-free G₂ metric exists on K₇. This supplement explores how departures from this torsion-free base (through moduli variation or quantum corrections) could generate the small effective torsion that enables physical interactions.
This supplement provides three proposed bridges:
Torsional dynamics: How departures from the torsion-free base could generate physical interactions. The topological value κ_T = 1/61 represents the geometric “capacity” for torsion.
Scale bridge: The formula m_e = M_Pl × exp(-(H* - L₈ - ln(φ))) derives the electron mass from Planck scale with <0.1% precision on the exponent
Cosmological evolution: Hubble tension resolution via dual topological projections H₀ = {67, 73}
All results emerge from the topological structure established in S1.
Important: This supplement explores THEORETICAL extensions of GIFT. Unlike S2 (which contains VERIFIED dimensionless relations), the content here involves additional assumptions and interpretive frameworks.
| Content | Status | Confidence |
|---|---|---|
| Torsion capacity κ_T = 1/61 | TOPOLOGICAL | High |
| Torsion-free metric exists (Joyce) | VERIFIED | Certain |
| RG flow identification λ = ln(μ) | THEORETICAL | Moderate |
| Scale bridge m_e formula | EXPLORATORY | Low-moderate |

The 33 dimensionless predictions (S2) do not depend on any content in this supplement.
In differential geometry, torsion measures the failure of infinitesimal parallelograms to close. For a connection ∇ on manifold M, the torsion tensor T is defined by:
\[T(X, Y) = \nabla_X Y - \nabla_Y X - [X, Y]\]In components:
\[T^k_{ij} = \Gamma^k_{ij} - \Gamma^k_{ji}\]Levi-Civita connection: Unique torsion-free, metric-compatible connection
Torsionful connection: Preserves metric compatibility but allows non-zero torsion
The GIFT framework employs a torsionful connection arising from non-closure of the G₂ 3-form.
A 7-manifold M has G₂ holonomy if it admits a parallel 3-form φ:
\[\nabla \phi = 0\]Equivalent to closure conditions:
\[d\phi = 0, \quad d*\phi = 0\]Algebraic Reference Form
The reference form φ_ref = c × φ₀ (with c = (65/32)^{1/14}) determines the algebraic structure in a local orthonormal coframe. As explained in the Main paper (Section 3.4) and S1 (Section 11.2), this is not a globally constant form on K₇.
Global Solution Structure
On the compact TCS manifold K₇, the actual solution takes the form: \(\varphi = \varphi_{\text{ref}} + \delta\varphi\)
Joyce’s theorem guarantees a torsion-free metric exists when ‖T‖ < ε₀ = 0.1. PINN validation confirms ‖T‖_max = 4.46 × 10⁻⁴ (224× margin). The topological bound κ_T = 1/61 constrains the amplitude of deviations δφ.
Physical Interactions and Dynamics
The static torsion-free solution represents the classical ground state. Physical interactions may emerge through:
The value κ_T = 1/61 represents the geometric “capacity” for such dynamical deformations.
The magnitude κ_T is derived from cohomological structure:
\[\boxed{\kappa_T = \frac{1}{b_3 - \dim(G_2) - p_2} = \frac{1}{77 - 14 - 2} = \frac{1}{61}}\]Components:
| Term | Value | Origin |
|---|---|---|
| b₃ | 77 | Third Betti number (matter modes) |
| dim(G₂) | 14 | Holonomy constraints |
| p₂ | 2 | Binary duality factor |
| 61 | 77 - 14 - 2 | Net torsion degrees of freedom |
The inverse torsion capacity 61 admits multiple decompositions:
\[61 = \dim(F_4) + N_{gen}^2 = 52 + 9\] \[61 = b_3 - b_2 + \text{Weyl} = 77 - 21 + 5\] \[61 = \text{prime}(18)\]┌─────────────────────────────────────────────────────────────┐ │ IMPORTANT │ │ │ │ κ_T = 1/61 is the CAPACITY, the maximum torsion that │ │ K₇ topology permits while preserving G₂ holonomy. │ │ │ │ Joyce’s theorem guarantees a torsion-free metric exists │ │ on K₇ (i.e., T = 0 for that metric, by definition). │ │ │ │ The capacity 1/61 characterizes the manifold’s topology. │ │ The torsion-free solution exists by Joyce’s theorem. │ │ │ │ All 33 predictions use topology (via b₂, b₃, dim_G₂), │ │ NOT the realized torsion value. │ └─────────────────────────────────────────────────────────────┘
Status: TOPOLOGICAL (capacity bounds deviations from torsion-free base)
| Recent analyses using BAO data to constrain Einstein-Cartan torsion cosmology find bounds of order | T | ² < 10⁻³ at 95% CL. For example, Iosifidis et al. (2024) “Cosmological constraints on torsion parameters from BAO and CMB data” (EPJC 84, 1067) uses Planck+BAO data; similar analyses incorporating DESI DR1/DR2 data yield comparable bounds. |

| Literature bound | T | ² < 10⁻³ (95% CL, Einstein-Cartan models) | |
| GIFT capacity | κ_T² = (1/61)² ≈ 2.69 × 10⁻⁴ | ||
| Status | Compatible |
Caveat: These bounds apply to specific torsion parameterizations (typically scalar torsion modes in Einstein-Cartan theory). Direct comparison with GIFT’s topological κ_T = 1/61 requires model-dependent mapping between the G₂ torsion capacity and cosmological torsion parameters. The compatibility is indicative, not exact.
On a 7-manifold with G₂ structure, torsion decomposes into four irreducible representations:
\[T \in W_1 \oplus W_7 \oplus W_{14} \oplus W_{27}\]| Class | Dimension | Characterization |
|---|---|---|
| W₁ | 1 | dφ ∧ φ ≠ 0 |
| W₇ | 7 | *dφ - θ ∧ φ for 1-form θ |
| W₁₄ | 14 | Traceless part of d*φ |
| W₂₇ | 27 | Symmetric traceless |
Total: 1 + 7 + 14 + 27 = 49 = 7²
Torsion-free G₂: All classes vanish (dφ = 0, d*φ = 0)
GIFT framework: Controlled non-zero torsion with magnitude κ_T = 1/61.
The small but non-zero torsion enables:

If we parameterize fluctuations away from the exact solution using coordinates with physical interpretation:

|---|---|---|
| e | Electromagnetic | [0.1, 2.0] |

| φ | Electroweak/Higgs | [0.1, 1.5] |
From exploratory PINN reconstruction of torsionful G₂ structures (NOT the GIFT analytical solution):

| T_{πφ,e} | O(1/p₂) ~ 0.5 | CP violation |
| T_{eπ,φ} | O(κ_T/b₂b₃) ~ 10⁻⁵ | Jarlskog invariant |
Status: THEORETICAL EXPLORATION — not part of core GIFT predictions.
If physical interactions emerge from quantum fluctuations around the torsion-free base:
This mechanism is CONJECTURAL. The 18 proven predictions use only topology, not these torsion component values.
For curve x^k(λ) on K₇:
\[S = \int d\lambda \, \frac{1}{2} g_{ij} \frac{dx^i}{d\lambda} \frac{dx^j}{d\lambda}\]Standard Euler-Lagrange derivation yields:
\[\ddot{x}^m + \Gamma^m_{ij} \dot{x}^i \dot{x}^j = 0\]The full connection decomposes as Γ = {·} + K where {·} is Levi-Civita (Christoffel symbols) and K is the contorsion tensor. For locally constant metric (∂k g{ij} ≈ 0), the Christoffel symbols vanish and the torsion-induced correction dominates:
\[\boxed{\Delta\Gamma^k_{ij} = -\frac{1}{2} g^{kl} T_{ijl}}\]Note: This is the torsion-induced correction term, not the complete connection. In regions where metric gradients are significant, the full form Γ = {·} + K applies.
Physical meaning: In the regime where metric is approximately constant, acceleration arises primarily from torsion rather than metric gradients.

β-Function Evolution:
\[\frac{d\beta^k}{d\lambda} = \frac{1}{2} g^{kl} T_{ijl} \beta^i \beta^j\]Physical meaning: Evolution of β-functions (two-loop and higher) is determined by torsion.
Experimental bounds on time variation of α:
\[\left|\frac{\dot{\alpha}}{\alpha}\right| < 10^{-17} \text{ yr}^{-1}\]With:
| Γ | ~ κ_T/det(g) = (1/61)/(65/32) = 32/(61×65) ≈ 0.008 |
| v | = flow velocity |
Note: det(g) = 65/32 is TOPOLOGICAL (see S1).
| Constraint: | v | < 0.7 |
This gives:
\[\frac{\dot{\alpha}}{\alpha} \sim 3.0 \times 10^{-18} \times 0.008 \times (0.015)^2 \approx 10^{-24} \text{ s}^{-1}\]Well within experimental bounds.

Problem: How do dimensionless topological numbers acquire dimensions (GeV)?
GIFT predicts dimensionless ratios exactly:
But absolute masses require one reference scale.
The framework contains several natural scales:
| Scale | Value | Origin |
|---|---|---|
| Planck mass | M_Pl ~ 10¹⁹ GeV | Quantum gravity |
| Electroweak | v ~ 246 GeV | Higgs VEV |
| Electron mass | m_e ~ 0.511 MeV | Lightest charged fermion |
Question: Can the ratio m_e/M_Pl be derived from topology?
WARNING: EXPLORATORY CONTENT - The scale bridge formula below achieves 0.09% precision but involves assumptions (Lucas number selection, ln(phi) appearance) that lack geometric derivation. This section represents a working conjecture, not a proven result.

H* = 99 = b₂ + b₃ + 1:
L₈ = 47 = Lucas(8) = Lucas(rank_E₈):
ln(φ):
The scale bridge admits a more transparent form. Rewriting:
\[\frac{m_e}{M_{Pl}} = e^{-H^*} \times e^{L_8} \times e^{\ln(\phi)} = \phi \times e^{-(H^* - L_8)}\]Since H* - L₈ = 99 - 47 = 52 = dim(F₄):
\[\boxed{\frac{m_e}{M_{Pl}} = \phi \times e^{-\dim(F_4)}}\]The exponent is exactly the dimension of the exceptional Lie algebra F₄, which appears as the automorphism group of the exceptional Jordan algebra J₃(O).
Coherence argument: The golden ratio φ appears as a multiplicative factor (not in the exponent) to ensure consistency with inter-generation mass ratios:
| Ratio | Formula | Role of φ |
|---|---|---|
| m_μ/m_e | 27^φ | Exponent |
| m_e/M_Pl | φ × e^(-52) | Factor |
If inter-generation ratios are φ-powers of topological constants, then the absolute scale anchor must contain φ to maintain dimensional coherence of the golden ratio structure.
The choice of Lucas numbers L_n rather than Fibonacci numbers F_n is structurally determined:
Reason 1: Engagement constraint
Reason 2: GIFT decomposition
Lucas and Fibonacci satisfy L_n = F_{n-1} + F_{n+1}. For n = 8:
\[L_8 = F_7 + F_9 = 13 + 34 = 47\]where F₇ = 13 = α_sum^B and F₉ = 34 = d_hidden in GIFT. Thus:
\[\boxed{L_8 = \alpha_{sum}^B + d_{hidden} = 13 + 34 = 47}\]The Lucas number at E₈ rank decomposes as the sum of two independent GIFT constants.
Reason 3: Dimensional consistency
Using F8 = 21 would give H* - F8 = 99 - 21 = 78 = dim(E6), yielding exp(-78) = 10^-34 and m_e = 10^-12 MeV, orders of magnitude too small.
Reason 4: F₄ connection
The resulting exponent 52 = dim(F₄) = 4 × 13 = p₂² × α_sum^B connects the scale bridge to the automorphism algebra of J₃(O), which itself appears in the muon ratio m_μ/m_e = 27^φ through dim(J₃(O)) = 27.
Why is m_e « M_Pl? The ratio m_e/M_Pl ~ 10⁻²³ seems to require extreme fine-tuning.
The hierarchy is topological, not fine-tuned:
\[\frac{m_e}{M_{Pl}} = \exp(-(H^* - L_8 - \ln\phi)) = \exp(-51.52)\]The large suppression arises because:
These are discrete topological invariants, not tunable parameters.
The hierarchy exponent 52 = H* - L₈ = 99 - 47 is an integer determined by topology.
Alternative expressions for 52:
Given m_e from the scale bridge, all other masses follow from GIFT ratios:

m_e = 0.511 MeV

The quark sector presents a qualitatively different challenge from leptons. While one ratio is established:
\[\frac{m_s}{m_d} = p_2^2 \times \text{Weyl} = 4 \times 5 = 20\]Status: VERIFIED (see S2, Section 12)
Absolute quark masses and other ratios remain open. Although GIFT expressions matching experimental values can be constructed, no geometric derivation analogous to the lepton sector has been established.
Key differences from leptons:
Deferred: Complete quark mass derivations require establishing a geometric principle comparable to the lepton sector’s Jordan algebra connection.

Two measurement classes give systematically different H₀ values:

| SH0ES Cepheids | 73.0 ± 1.0 | z < 0.01 (local) |

Both values emerge as distinct topological projections of K₇:
\[\boxed{H_0^{\text{CMB}} = b_3 - 2 \times \text{Weyl} = 77 - 10 = 67}\] \[\boxed{H_0^{\text{Local}} = b_3 - p_2^2 = 77 - 4 = 73}\]The Hubble tension equals twice the number of fermion generations.

The Hubble tension reflects a dimensional projection duality:

| Local (z < 0.01) | p₂² = 4 | Spatial dimensions of effective 4D spacetime |
CMB/Early Universe (Planck):
Local/Late Universe (SH0ES):
The 6 degrees of freedom “frozen” between early and late universe correspond to the 3 generations × 2 chiralities of fermions that decouple during cosmological evolution. This provides a physical mechanism for the transition from early to late universe expansion rates.

The Weyl Triple Identity (S1, Section 2.3) establishes Weyl = 5 as a structural constant. Its square root appears in the dark sector:
\[\frac{\Omega_{DE}}{\Omega_m} = \sqrt{\text{Weyl}} = \sqrt{5} = 2.236\]The √5 ratio suggests a geometric relationship between dark energy and matter:
| Sector | Density | Origin |

The ratio b₂/rank_E₈ = 21/8 = 2.625 matches φ² to 0.27% because:

Two distinct structures appear in cosmological predictions:

| Ω_DE | ln(2) = ln(p₂) | Binary duality |
| Ω_DE/Ω_DM ≈ φ² | φ² = (3+√5)/2 | Golden ratio from Weyl |
The ratio Ω_DE/Ω_DM = 21/8 ≈ 2.625 ≈ φ² connects to √5 via: \(\phi^2 = \phi + 1 = \frac{3 + \sqrt{5}}{2}\)
Thus √5 appears indirectly through the golden ratio in dark sector ratios, while ln(2) appears directly in absolute densities. Both structures derive from GIFT constants (Weyl = 5, p₂ = 2) but encode different geometric aspects: Weyl captures pentagonal/exceptional structure, while p₂ captures binary duality.

The hierarchy parameter τ = 3472/891 ≈ 3.896 has powers that lie remarkably close to integers with GIFT-theoretic significance:
| Power | Value | Lower | Upper | Target | Interpretation |
|---|---|---|---|---|---|
| τ² | 15.18… | 15 | 16 | — | — |
| τ³ | 59.17… | 59 | 60 | — | — |
| τ⁴ | 230.57… | 230 | 231 | 231 | 3 × 7 × 11 = N_gen × b₃ |
| τ⁵ | 898.48… | 898 | 899 | 900 | h(E₈)² = 30² |
GIFT-theoretic interpretations:
Formal verification:
These are rigorous bounds proven in Lean 4 using integer arithmetic:
tau4_bounds: 230 × q⁴ < p⁴ < 231 × q⁴ where τ = p/q = 3472/891tau5_bounds: 898 × q⁵ < p⁵ < 899 × q⁵Status: NUMERICAL OBSERVATION (the proximity to GIFT-significant integers is formally verified, but the significance of this proximity is not yet understood)
Epistemic note: These observations may be coincidental. The fact that τ⁴ and τ⁵ approach but don’t exactly equal these targets suggests either:
Lean 4 verification: tau_power_bounds_certificate
Torsional connection: \(\Gamma^k_{ij} = -\frac{1}{2} g^{kl} T_{ijl}\)
Geodesic equation: \(\frac{d^2 x^k}{d\lambda^2} = \frac{1}{2} g^{kl} T_{ijl} \frac{dx^i}{d\lambda} \frac{dx^j}{d\lambda}\)
Scale bridge: \(m_e = M_{Pl} \times \exp(-(H^* - L_8 - \ln(\phi)))\)
Topological torsion: \(\kappa_T = \frac{1}{b_3 - \dim(G_2) - p_2} = \frac{1}{61}\)
Dark energy: \(\Omega_{DE} = \ln(2) \times \frac{H^* - 1}{H^*} = 0.6861\)
Hubble values: \(H_0^{CMB} = b_3 - 2 \times \text{Weyl} = 67\) \(H_0^{Local} = b_3 - p_2^2 = 73\)
