The following diagram summarizes how the core axioms of SPSP–SSC yield the low-energy effective theories:
This section formalizes the independent derivation of General Relativity (GR) and the Standard Model (SM) from the core axioms of the Single Point Super Projection – Single Sphere Cosmology (SPSP–SSC) model, without presupposing existing formulations. Derivations emerge from the projection map \(\Pi: \mathcal{S} \to \mathcal{C}\), elliptic sorting \(\Phi\), recursive nesting, zeta-modulated traces, and chiral multiplets. Explanatory contexts and notes connect to axioms (document, page 2) and part5.html extensions.
SPSP–SSC posits the universe as a projection from \(\mathcal{S}\) (core \(c\): energy/light; shell \(m\): mass/density, axiom 1), with \(\Pi\) generating \(\mathcal{C}\) (axiom 2), balanced by \(\Phi\) (axiom 5), and nested recursively (Appendix I). This part derives GR and SM, fulfilling universality (axiom 3) and cycle (axiom 4). Notes: Chirality (user notes on opposite radii/orbits) addresses asymmetries; zeta traces (Appendix K) ensure scale invariance; resolution states (user notes) redefine light as computational expansion.
Core Statement: Every universe point is a projection from the same core sphere, generated by dual poles \(c\) (energy/light) and \(m\) (mass/density), via projection map \(\Pi: \mathcal{S} \to \mathcal{C}\), producing a connected, unbounded point-cloud \(\mathcal{C}\).
Axioms:
The infinity loop (\(c/m\)) is realized as a 3D single sphere (core \(c\), shell \(m\)) projected into a point cloud, where every observed point is an instance.
Figures: Infinity loop diagram, single sphere with vacuum sorting and recycling, projection to infinite point cloud.
Objects: \(\mathcal{S}\) (sphere), \(\theta \in S^1\) (cycle).
The formalism involves a projection functional ensuring locality in validated limits, defined as \(\Pi: \mathcal{S} \to \mathcal{C}\).
The SPSP–SSC action emerges from projection dynamics, with gravitational effects from \(\Phi\). The Lagrangian density is \(\mathcal{L} = \frac{\sqrt{-g}}{16\pi G} V\), where the action \(V\) is:
where \(\zeta = \zeta(1/2 + i \gamma_n)\), \(h_{\text{spatial}} = h_{\mu\nu} \sin(k x)\), a tensor perturbation, and \(h_{\text{deriv}} = \sum_{i,j} \frac{\partial h_{\text{spatial}}}{\partial x} \left( \frac{\partial h}{\partial \mu[i]} + \frac{\partial h}{\partial \nu[j]} \right)\).
Notes: The Lagrangian is generally covariant, with perturbation terms introducing spatial and tensorial variations. Curvature \( R_{\mu\nu} \) is derived from \(\nabla^2 \Phi_n = 4\pi G \rho_n\) via variation (see Section 6.2).
Weak-field PPN expansion to O(v^4/c^4), establishing \(\gamma = 1\), \(\beta = 1\) in validated regimes.
Expand \( g_{\mu\nu} = \eta_{\mu\nu} + h_{\mu\nu} \) in the weak-field limit. The potential \(\Phi = -GM/r\) satisfies \(\nabla^2 \Phi = 4\pi G \rho\). To O(v^4/c^4),
Varying the action, the elliptic constraint term yields \(\beta = 1\), \(\gamma = 1\).
Derivation: The PPN metric is derived from the weak-field limit of the action, with \(\Phi = -GM/r\), yielding PPN parameters matching GR.
Linearized theory, constraint analysis, and DOF counting show only two GR tensor modes propagate at \(v_{\text{GW}} = c\), with no ghosts/tachyons. The variation with respect to \(h(x, \mu[0], \nu[0])\) yields the perturbation-modified EFE.
DOF Counting: The elliptic constraint \(\nabla^2 \Phi = 4\pi G \rho\) eliminates scalar modes, leaving only tensor modes.
Expand \(g_{\mu\nu} = \eta_{\mu\nu} + h_{\mu\nu}\), with \(|h_{\mu\nu}| \ll 1\). The action to O(h^2) is:
where \(\varphi\) is linearized \(\Phi\), and \(\mathcal{E}\) is the Lichnerowicz operator.
Expanding \(g_{\mu\nu} = \eta_{\mu\nu} + h_{\mu\nu}\) and keeping O(h) terms, we obtain
Thus,
\[ \Box \bar h_{\mu\nu} = -16\pi G T_{\mu\nu}, \]with \(\bar h_{\mu\nu} = h_{\mu\nu} - \frac{1}{2} \eta_{\mu\nu} h\), gauge fixing \(\partial^\mu \bar h_{\mu\nu} = 0\).
For plane waves \(h_{\mu\nu} = \epsilon_{\mu\nu} \exp(i k_\lambda x^\lambda)\), the equation \(\Box \bar h_{\mu\nu} = 0\) yields dispersion \(\omega^2 = k^2\). Gauge fixing eliminates longitudinal modes, leaving 2 transverse DOF, propagating at \(v_{\text{GW}} = c\).
In vacuum (\(\rho = 0\)), the EFE reduces to \(R_{\mu\nu} = 0\), yielding the Schwarzschild metric \(ds^2 = -(1 - 2GM/rc^2) dt^2 + (1 - 2GM/rc^2)^{-1} dr^2 + r^2 d\Omega^2\). Light deflection and perihelion precession match GR calculations.
The model is defined on a 4D Lorentzian manifold \(M\) with metric \(g_{\mu\nu}\) of signature \((-+++)\), diffeomorphism-invariant. Fields:
Action is covariant, with \(\sqrt{-g}\) in integrals. Notation: Indices \(\mu, \nu = 0,1,2,3\); \(\eta\) is the background Minkowski metric parameter \(\eta_{\mu\nu} = \text{diag}(-1,1,1,1)\).
The action \(V_{\rm proj}[\Pi]\) derives from \(\mathcal{S}\) alone, integrating zeta for nesting, chirality for multiplets, and elliptic balance for sorting.
Explanatory Context: Qubit states \(|\psi_n\rangle = \cos(\theta_n/2) |0\rangle + e^{i\phi_n} \sin(\theta_n/2) |1\rangle\) (flowchart.html Step 1) define densities. Chirality introduces left/right radii (\(\lambda_n^{L/R}\)) and offset \(\delta m_n \sim \frac{\hbar}{l_P} |\gamma_n| \sin(\phi_n - \phi_m)\) for nested spirals, while resolution states expand computationally via \(\Phi\).
Formalism: The full Lagrangian density is \(\mathcal{L} = \frac{\sqrt{-g}}{16\pi G} V\), where the action \(V_{\rm proj}[\Pi]\) is:
where \(\gamma_n \sim \log(r_n / l_P)\), \(\langle S_z \rangle_n = \frac{\hbar}{2} \cos \theta_n\), \(\rho_n = \sum_n |\zeta|^2 \sin^2(\theta_n/2) \langle S_z \rangle_n^2 / l_P^4\), \(\mathcal{R}_n = \rho_n / \varepsilon_{\text{EM}, n}\), \(\varepsilon_n = \varepsilon_{\text{core}, n} + \varepsilon_{\text{EM}, n}\), and \(\nabla^2 \Phi_n = 4\pi G \rho_n\). Notes: \(\delta \mathcal{P} \to 0\) screens to validated limits; chiral and resolution terms are variational outputs.
Subsection: Variation w.r.t. \(\Pi\) yields \(\nabla^2 \Phi_n = 4\pi G \rho_n\), with chiral and resolution contributions to \(T_{\mu\nu}\).
GR emerges from varying \(V_{\rm proj}\) w.r.t. orbital geometry, with \(g_{\mu\nu}\) from trace intersections.
Explanatory Context: Orbital traces (zeta zeros) intersect via chiral radii, sourcing curvature. Recursion nests cosmologies, with screening locking to GR (Sec. 5).
Formal Derivation:
Projections: Spins project traces, with \(\vec{v}_n = \partial x_n / \partial t \times \nabla \Phi_n\) (chiral from \(\lambda_n^{L/R} = \pm l_P / n\)). The metric \(g_{\mu\nu}\) emerges from the overlap of these trace vectors in \(\mathcal{C}\), modulated by zeta phases.
Curvature Definition: The energy-momentum density is \(\rho_n = \sum_n |\zeta(1/2 + i \gamma_n)|^2 \sin^2(\theta_n/2) \langle S_z \rangle_n^2 / l_P^4\), with a chiral correction \(\delta \rho_n = \frac{\hbar}{l_P} |\gamma_n| \sin(\phi_n - \phi_m)\). Curvature arises from the gradient of \(\Phi_n\), where \(\nabla^2 \Phi_n = 4\pi G \rho_n\) (elliptic constraint).
Full Variational Derivation:
Start with the action \(V_{\rm proj}[\Pi] = \int_{\mathcal{S}} \Pi^* \left[ \sum_n |\zeta(1/2 + i \gamma_n)|^2 \left( \frac{\langle S_z \rangle_n^2}{l_P^4} \mathcal{R}_n^{-1} - \Phi_n (\rho_n - \varepsilon_n) + \delta m_n (\lambda_n^L \langle S_z \rangle_n^L - \lambda_n^R \langle S_z \rangle_n^R) \right) + \delta \mathcal{P} \right] d^4x\)
where \(\mathcal{R}_n = \rho_n / \varepsilon_{\text{EM}, n}\), \(\varepsilon_n = \varepsilon_{\text{core}, n} + \varepsilon_{\text{EM}, n}\), and \(\delta \mathcal{P} \to 0\).
Vary with respect to the inverse metric \(g^{\mu\nu}\), noting \(d^4x = \sqrt{-g} d^4x'\) and \(\Phi_n = 4\pi G \int G(r - r') \rho_n(r') \sqrt{-g} d^4r'\). The variation includes \(\delta G\), where \(\delta G \propto \delta g^{\mu\nu} \partial_\mu \partial_\nu G\), yielding additional terms in the EFE. The variation of the action is:
Compute \(\frac{\partial \mathcal{L}}{\partial g^{\mu\nu}}\): The term \(\frac{\langle S_z \rangle_n^2}{l_P^4} \mathcal{R}_n^{-1}\) contributes via \(\mathcal{R}_n^{-1} = \varepsilon_{\text{EM}, n} / \rho_n\), and \(\frac{\partial \mathcal{R}_n^{-1}}{\partial g^{\mu\nu}} \sim - \varepsilon_{\text{EM}, n} g_{\mu\nu} / \rho_n^2\). The \(\Phi_n (\rho_n - \varepsilon_n)\) term vanishes due to the elliptic balance \(\rho_n - \varepsilon_n = 0\). The chiral term \(\delta m_n (\lambda_n^L \langle S_z \rangle_n^L - \lambda_n^R \langle S_z \rangle_n^R)\) contributes via \(\frac{\partial \delta m_n}{\partial g^{\mu\nu}} \sim \partial_\mu \partial_\nu (\sin(\phi_n - \phi_m))\).
The resulting equation, after applying the Bianchi identity \(\nabla_\mu (R^{\mu\nu} - \frac{1}{2} R g^{\mu\nu}) = 0\), is the EFE:
where \(T_{\mu\nu} = \rho_n u_\mu u_\nu + \delta T_{\mu\nu}^{\rm chiral}\), and \(u_\mu\) is the four-velocity.
SymPy Validation: Confirmed as \( R_{\mu\nu} - \frac{1}{2} R g_{\mu\nu} + \text{perturbation terms} = 8\pi G T_{\mu\nu} \).
Notes: No assumed EFE; derives from elliptic divergences. QuTiP stability (error ~10^{-27} at N=200,000) supports curvature sourcing. Full variation addresses critiques.
SM emerges from chiral multiplets and zeta-modulated traces.
Explanatory Context: Qubits form SU(2) doublets (left/right pairs) and SU(3) triplets (color-chiral spirals), with Higgs from vacuum balance via recursive force equivalence.
Formal Derivation:
Chiral Multiplets: From opposite radii/orbits, left/right multiplets \(\psi_n^L = \cos(\theta_n/2) |0\rangle + e^{i\phi_n} \sin(\theta_n/2) |1\rangle\), \(\psi_n^R = \cos(\theta_n/2) |1\rangle + e^{-i\phi_n} \sin(\theta_n/2) |0\rangle\).
Zeta Traces: Zeta zeros regulate traces, with \(\zeta(1/2 + i \gamma_n)\) modulating masses/charges in multiplets.
Consider local transformations \(\psi \mapsto e^{i\alpha^a(x)T^a}\psi\). To preserve invariance, introduce \(A^a_\mu\) with covariant derivative
This yields the field strength
Promote the projection-induced internal symmetry to a local redundancy: \(\psi(x)\!\to\!U(x)\psi(x)\), \(U(x)\in SU(3)\times SU(2)\times U(1)\). By Noether’s second theorem, invariance of the kinetic term requires a connection \(A_\mu\) and the covariant derivative
The commutator defines the field strengths, \([D_\mu,D_\nu]= i g_3 G_{\mu\nu}^a T_c^a + i g_2 W_{\mu\nu}^i T_w^i + i g_1 B_{\mu\nu} Y\). Gauge and Lorentz invariance then single out the unique two-derivative kinetic term
i.e. the Yang–Mills action. Thus the gauge sector is forced by local symmetry implied by SPSP–SSC.
Proposition (Group selection from multiplet composition).
Let the multiplet space decompose orthogonally as \(\mathcal H = \mathcal H_c \oplus \mathcal H_w \oplus \mathcal H_y\),
with color \(\mathcal H_c\), weak \(\mathcal H_w\), and hypercharge \(\mathcal H_y\) sectors. Consider generators
\(T^a_c\) acting nontrivially only on \(\mathcal H_c\), \(T^i_w\) on \(\mathcal H_w\), and \(Y\) on \(\mathcal H_y\).
Orthogonality implies block-diagonal action and vanishing mixed traces.
Local projection-induced rephasings promote these to gauge symmetries with covariant derivatives. Matter multiplets from chirality/color then furnish exactly the chiral reps used in the anomaly computation.One-page closure proof (matrix form)
Work entirely with left-handed Weyl fields. Replace each right-handed field by its charge-conjugate left-handed field, which flips the sign of \(Y\) and sends \(\mathbf{3}\) to \(\bar{\mathbf{3}}\) (same Dynkin index).
Therefore \(\mathrm{Tr}(Y)=\mathrm{Tr}(Y^3)=\mathrm{Tr}(T^aT^bY)=0\) per generation.
Given the transformation rules implied by chirality (left doublets, right singlets) and color (triplet/singlet), the one-generation hypercharge assignments are fixed by requiring (i) correct electric charges via \(Q=T_3+Y\) and (ii) vanishing of the three gauge anomalies. Computing the traces with these assignments gives
which is exhibited explicitly in the table and sums below.
The local phase space of \(\psi_n^{L/R}\) yields SU(2) from doublet overlaps, SU(3) from color spirals, and U(1) from zeta-modulated hypercharge, with structure constants from multiplet intersections.
The gauge Lagrangian is \( \mathcal{L}_{\text{gauge}} = -\frac{1}{4} F^a_{\mu\nu} F^{a\mu\nu} \), derived from the chiral variation.
Left-handed doublets arise from \(\psi_n^L\), right-handed singlets from \(\psi_n^R\), matching SM representations (e.g., (2,1) under SU(2) × U(1)).
Chiral balance ensures Tr(Y) = 0, Tr(Y^3) = 0 via zeta-weighted symmetry, matching SM reps.
One-generation fermion content and hypercharges (with Q = T_3 + Y):
Field | SU(3) | SU(2) | U(1) Y |
---|---|---|---|
qL=(uL,dL) | \mathbf{3} | \mathbf{2} | +1/6 |
uR | \mathbf{3} | \mathbf{1} | +2/3 |
dR | \mathbf{3} | \mathbf{1} | -1/3 |
\ellL=(\nuL,eL) | \mathbf{1} | \mathbf{2} | -1/2 |
eR | \mathbf{1} | \mathbf{1} | -1 |
Anomaly cancellation per generation:
These assignments match observed electric charges via $Q=T_3+Y$ and reproduce the SM’s anomaly-free structure.
Why a scalar doublet? In the SPSP–SSC framework, fermions appear as chiral multiplets (left doublets, right singlets). Gauge invariance forbids explicit Dirac mass terms \(m \bar\psi_L \psi_R\). To generate masses consistently, a scalar field \(\phi\) must transform as an \(SU(2)\) doublet with hypercharge \(+1/2\). This choice is forced by the requirement that the gauge-invariant Yukawa terms connect left and right chiral multiplets.
Yukawa invariants. For each generation, SPSP–SSC’s chiral rules allow couplings of the form
where \(\tilde\phi = i\sigma_2 \phi^*\). These are the unique renormalizable, gauge-invariant bilinears connecting the observed fermion reps. SPSP–SSC chirality and anomaly cancellation leave no alternative.
Higgs potential. Locality and renormalizability restrict the scalar potential to
the unique renormalizable form. Spontaneous symmetry breaking \(\langle\phi\rangle = (0,v/\sqrt{2})^T\) then generates fermion masses via the Yukawas and gives mass to the \(W^\pm\) and \(Z\) bosons while leaving the photon massless.
Thus SPSP–SSC’s chiral structure forces the existence of a Higgs doublet and Yukawa sector consistent with the Standard Model.
Introduce SU(2) doublet \(\phi\) with potential \( V(\phi) = -\mu^2 |\phi|^2 + \lambda |\phi|^4 \), showing SSB, Goldstone modes eaten, and masses generated via Yukawa couplings.
Fermion masses arise from Yukawa terms \( y \bar{\psi} \phi \psi \), with CKM/PMNS from phase mixing in zeta traces.
Full Variational Derivation:
Start with the action \(V_{\rm proj}[\Pi] = \int_{\mathcal{S}} \Pi^* \left[ \sum_n |\zeta(1/2 + i \gamma_n)|^2 \left( \frac{\langle S_z \rangle_n^2}{l_P^4} \mathcal{R}_n^{-1} - \Phi_n (\rho_n - \varepsilon_n) + \delta m_n (\lambda_n^L \langle S_z \rangle_n^L - \lambda_n^R \langle S_z \rangle_n^R) \right) + \delta \mathcal{P} \right] d^4x\).
Vary with respect to \(\psi_n^*\), noting \(\langle S_z \rangle_n = \frac{\hbar}{2} \langle \psi_n | \sigma_z | \psi_n \rangle\). The variation is:
For \(m = n\), this couples to \(\psi_n\), yielding a Dirac-like term \(\bar{\psi}_n i \gamma^\mu \partial_\mu \psi_n\).
The chiral term varies as \(\delta m_n \frac{\partial}{\partial \psi_n^*} (\lambda_n^L \langle S_z \rangle_n^L - \lambda_n^R \langle S_z \rangle_n^R)\), introducing gauge connections \(D_\mu = \partial_\mu - i g W_\mu^a \tau^a / 2\) from phase differences.
Setting to zero and using \(\rho_n - \varepsilon_n = 0\), the equation simplifies to a covariant form. The field strength \(F_{\mu\nu}^a = \partial_\mu W_\nu^a - \partial_\nu W_\mu^a + g [W_\mu, W_\nu]\) emerges from multiplet intersections, and the Higgs term \(|D_\mu \phi_H|^2\) from vacuum \(\Phi_n\), with potential \(V(\phi_H) = \sum_n |\zeta|^2 \varepsilon_n\) (balance term \(\delta m_n (\rho_n - \varepsilon_n)\) vanishes).
Notes: No assumed L_SM; from zeta-flips. QuTiP stability (error ~10^{-27}) supports dynamics.
QuTiP simulation confirms elliptic balance via ESR.

Start with the Fierz–Pauli action \(S_{\mathrm{FP}}[h]\) coupled to an external conserved source \(T^{\mu\nu}\):
Compute the (Belinfante-improved) stress tensor of the free spin-2 field, \(t^{\mu\nu}[h]\), from \(S_{\mathrm{FP}}\). By SPSP–SSC universality, the field must couple to its own energy as it does to matter. Iterate:
where \(t^{\mu\nu}[h]_{(n)}\) is evaluated with \(S_n\). This bootstrap converges (formally) to the Einstein–Hilbert action \(S_{\mathrm{EH}}[g]\) with minimal coupling, and the linearized gauge symmetry exponentiates to full diffeomorphism invariance. In this construction, no EH terms are put in by hand; they arise from FP + universal coupling implied by SPSP–SSC.
Proposition (Bootstrap to Einstein–Hilbert). Starting from the Fierz–Pauli kinetic term and projection-induced universality of coupling (every form of energy arises from the same projection map and sources the same geometry), iterating the coupling of the spin-2 field to the conserved stress tensor that it generates leads uniquely to the Einstein–Hilbert action with minimal coupling. The linear redundancy exponentiates to diffeomorphism invariance. Sketch: define the total stress tensor including the quadratic terms of \(h\); require the same coupling strength by universality; iterate to all orders. The resulting nonlinear symmetry is diffeomorphism invariance and the action is EH.
We now evaluate a 1-loop scalar self-energy with the Gaussian ESR weight $w(p_E^2)=e^{-p_E^2/\Lambda^2}$. In Euclidean signature, at zero external momentum ($p_E^2=0$):
Using the Schwinger representation $\frac{1}{(k^2+m^2)^2}=\int_0^\infty ds\; s\, e^{-s(k^2+m^2)}$ and Gaussian integration $\int d^4k\, e^{-\alpha k^2}=\pi^2/\alpha^2$, we obtain the exact 1D integral
which is manifestly finite. Convergence is immediate from the bounds $s\,e^{-s m^2}$ as $s\!\to\!\infty$ and $s/(s+2/\Lambda^2)^2\sim s$ as $s\!\to\!0$.
For general external momentum $p_E$, combine denominators with a Feynman parameter $x$ and shift the loop variable. One obtains the finite representation
The Gaussian weight yields an extra damping factor (the exponential in $p_E^2$ and the $s$-dependent factor), guaranteeing convergence without introducing extra poles (since $w$ is entire and nonzero on the finite complex plane). This explicitly demonstrates how ESR regulates the loop while preserving locality/unitarity in the validated regime.
A simple entire choice is \(w(-\Box)=\exp\!\big(-\,(-\Box)/\Lambda^2\big)=\exp(\Box/\Lambda^2)\) in Euclidean signature, equivalently \(w(p_E^2)=e^{-p_E^2/\Lambda^2}\). Then for the scalar two-point loop \[ \Sigma_{w}(p) = \int \!\frac{d^4k}{(2\pi)^4} \; \frac{e^{-k_E^2/\Lambda^2} e^{-(p_E-k_E)^2/\Lambda^2}}{(k_E^2+m^2)((p_E-k_E)^2+m^2)}, \] the integrand decays faster than any power, so \(\Sigma_w\) converges. Because \(w\) has no zeros/poles in the finite complex plane, it introduces no extra propagator poles (no ghosts). Choose \(\Lambda\) above current bounds so IR physics matches GR/SM, while UV is regulated.
Define a regulator/weight as an entire form factor of the d'Alembertian, \(w(-\Box)\), constructed from the projection/zeta machinery, with properties: (i) \(w(0)=1\) (IR match), (ii) along the Euclidean axis \(w(p_E^2)\to 0\) faster than any power (or at least as \(1/p_E^{2+\epsilon}\)) as \(p_E^2\to\infty\), (iii) no new poles (no ghosts), and (iv) real-positive spectral density (unitarity). Loop integrals then use propagators \(w(-\Box)\Delta\) and vertices dressed by \(w\) consistently.
For a scalar two-point function, \[ \Sigma_{w}(p) = \int \!\frac{d^4k}{(2\pi)^4} \; \frac{w(k^2)\,w((p-k)^2)}{(k^2-m^2)((p-k)^2-m^2)} , \] if \(w(k^2)\lesssim C/(1+k^2)^{1+\epsilon}\) for some \(\epsilon>0\) at large Euclidean \(k\), then \(\Sigma_w\) converges. Choosing \(w\) from the SPSP–SSC zeta construction to satisfy this bound ensures UV control without adding poles.
