φ-segmentation geometry

Rebuilt from the archived SEGMENTED_SPACETIME/Slider.html, with no CodePen or iframe. This is an explanatory geometry of exponential radial levels—not a derivation of the canonical metric.

rn = r₀eλn

The golden-ratio step is λ=lnφ≈0.4812. Moving away from it is a deliberate conceptual comparison.

Canonical field mapping

How Ξ changes clocks and radial rulers

The same normalized radius drives Ξ, D=1/(1+Ξ), and s=1/D. Concentric circles are coordinate spheres; the gold radial intervals show the corresponding proper radial scale of the diagonal ansatz.

P0 branch audit

C² continuity microscope

Zoom into either join and inspect Ξ, dΞ/dx and d²Ξ/dx² on both sides. This makes the six Hermite endpoint conditions visible rather than merely asserting “smoothness”. The displayed Δ values compare finite numerical probes immediately to either side; exact endpoint identities are tested separately.

SSZ-METRIC_COMPLETE · canonical pure metric

Metric, inverse and local-frame explorer

This reconstruction follows the repository’s primary chain \(\Xi\rightarrow D,s\rightarrow g_{\mu\nu}\), rather than plotting two detached coefficients. Compare the diagonal static form with the repository’s non-diagonal flow form; inspect algebraic identities, signature, determinant and local radial null slopes at the same event.

Diagonal form

\[\frac{g_{\mu\nu}}{\{c^2,1,r^2,r^2\sin^2\theta\}}=\operatorname{diag}(-D^2,s^2,1,1),\quad Ds=1\]

The exact repository identity gives \(\det g=-c^2r^4\sin^2\theta\) away from spherical-coordinate axes.

Flow form

\[ds^2=-c^2(1-\beta^2)dt^2+2\beta c\,dt\,dr+dr^2+r^2d\Omega^2\]

This is a coordinate representation provided by the repository. A nonzero cross term is not an additional force or a rotating solution.

P0 boundary

At \(r\to0^+\), the diagonal coefficients tend to finite values \(D^2\to1/4\) and \(s^2\to4\), but \(R\sim3/(2r^2)\) and \(K\sim9/(4r^4)\). Component finiteness, determinant identities and Lorentzian signature do not establish a regular areal centre.

Static-clock comparison

Two clocks at different radii

Coordinate time is shared by the diagram; each static clock accumulates its own proper time dτ=D(r)dt. This animation distinguishes a comparison of clocks from a claim that photons locally slow down.

Spectral-line shift explorer

Choose an emitted wavelength and two static radii. The line moves according to 1+z=D(ro)/D(re). Doppler motion, plasma and radiative transfer are deliberately not hidden inside the result.

Radial null-path integration

For ds²=0 and dΩ=0, dr/dt=±cD²(r). The animation integrates the coordinate slope while reiterating that every local freely falling observer measures light at c.

Weak-field reference

Light-deflection geometry

This module visualises the leading PPN expression α=(1+γ)rs/b with γ=1. It is an intentionally scaled diagram; screen curvature is not a ray-traced strong-field prediction.

α = 2rs/b =

For b≫rs, increasing b reduces the leading deflection. Near the compact object, the weak-field approximation is not sufficient.

Metric-derived diagnostic

Null and timelike orbit diagnostics

For the declared static spherical ansatz, the circular-null diagnostic is \(A(r)/r^2\) with \(A=D^2\). The same shared metric engine now derives the critical-impact proxy and searches the circular-timelike \(L^2\) curve for a stationary minimum; none of these radii is hard-coded.

A bridge-localised stationary point may be sensitive to the matching prescription. Accessibility, stability, a complete rotating geometry and radiative transfer are still required before calling a feature an observed photon ring, ISCO or shadow.

Gaia-derived repository catalogue

Interactive SSZ Starmaps explorer

A faithful static-browser adaptation of the repository’s coordinate, filtering and comparison workflow. It uses 3,000 real catalogue stars with ICRS position, parallax distance, magnitude, colour, temperature and proper motion. The legacy constant Ξ/D columns are deliberately ignored because they conflict with the current P0 piecewise model.

galactic-year · source-level consistency audit

Solar Galactic Year: measurements, dynamics and clock rate

Follow the full inference chain instead of collapsing unlike quantities into one “orbit model”. The directly constrained angular motion, an adopted circular speed, the equivalent enclosed mass, the inadequate Sgr A* point-mass countermodel and the SSZ weak-field clock factor answer different questions.

Two observational routes

\[T_{\rm kin}=\frac{2\pi R_0}{\Theta_0},\qquad T_\mu=\frac{2\pi}{|\mu_l|}\]

The first route combines radius and adopted circular speed. The second reads the reflex angular motion of Sgr A*. They need not be identical because Θ₀, Solar peculiar motion and the angular observable are distinct inputs.

Dynamical consistency

\[M(<R_0)=\frac{\Theta_0^2R_0}{G},\qquad T_{\rm BH}=2\pi\sqrt{\frac{R_0^3}{GM_{\rm BH}}}\]

The equivalent enclosed mass encodes the extended Galactic potential. Sgr A* alone predicts about 1.49 km/s and a period of many billions of years, so it is a counterexample—not a Solar-orbit model.

Separate SSZ clock layer

\[\Xi=\frac{r_s}{2R_0},\quad D=(1+\Xi)^{-1},\quad \Delta T=T_{\rm kin}(D^{-1}-1)\]

The portal reports the weak-field proper-time increment in years per orbit. It does not multiply a point-mass trajectory into agreement with Galactic data.

Resolved audit finding: the generated JSON’s 1.492 km/s follows from applying \(v=\sqrt{GM/R}\) to Sgr A* alone; the README’s 247.8 km/s and 230 Myr use a Galactic-scale orbit. They are not competing SSZ predictions. The interactive comparison makes that category error visible and links to the source repository.

Chord-partition eigenmodes and φ convergence

Explore the repository’s parametric curve \(C(t;p,k,R)=(R\cos pt,R\sin kt)\). Integer winding pairs close exactly; consecutive Fibonacci pairs make \(k/p\) approach φ. The geometry visualises the tested construction without claiming that the curve derives spacetime microphysics.

The suite tests closure, derivatives, perimeter scaling, numerical stability and φ convergence. Those mathematical tests do not establish a physical segmentation mechanism.

Schumann mode and common-shift explorer

Synthetic recovery tests validate the pipeline’s ability to recover an injected common signal. Real-data preference additionally needs the licensed external datasets and environmental covariates.

Standard rotating-loop reference

Counter-propagating signals on a rotating loop

The detector moves while two signals traverse opposite directions. Their reunion times differ. The leading standard expression is Δt≈4AΩ/c²; the animation uses scaled units for visibility.

Δt = s
P0 asymptotic diagnostic

Approaching the areal centre

On logarithmic axes, the canonical diagonal continuation has R∼3/(2r²) and K∼9/(4r⁴). The steeper K line exposes why finite A→1/4 does not imply central regularity.

Interpretation: these are stated leading asymptotics, not a numerical solution at r=0. Both invariants diverge as the radius tends to zero.
