QDS Core Validation Labs • Front Door

One place to launch the hard QDS tests: H₀ variance, galaxy rotation, and kernel microphysics. No cloud, no fairy dust — just χ² and whether it passes.

Real datasets • ROTMOD · H(z) · kernel shapes
Kernel fixed • σ², τc, λc shared across labs
Phone-first • offline · reproducible · exportable

Cosmology • Hubble variance

H₀ Variance Lab public toy·sim + table

H₀ Variance Lab σ(H)/H = A R−p
Law: A = 0.017, p = 0.35
Scale: 5–100 Mpc
Enter survey radii and measured fractional scatter, compare against the QDS variance law, and see pass/fail vs tolerance. Good for showing the small-scale excess and large-scale floor.
Open H₀ Variance Lab View table / chart
Evidence: H₀ variance vs QDS law. Use when people ask “where’s the cosmology in this?”

Galaxies • rotation curves

Rotation Curve Labs ROTMOD public curves

Rotation Curve Tester toy · per-point
Law: vQDS = vN √(1 + α e−r/λc)
Custom lists / quick checks
Manual entry of r, Newtonian vN and observed v, then compare against the QDS-modified law. Useful for whiteboard-style demos and sanity checks without touching the full ROTMOD stack.
Open Rotation Lab Newtonian vs QDS view
Evidence: shape-level fit intuition. Use when you want to explain the modification by hand.
RotMod Extreme Lab batch · χ²-first
Inputs: ROTMOD CSVs (public)
Outputs: χ²base, χ²QDS, Δχ²
Full rotation-curve fitter on the public ROTMOD set. For each galaxy, compute χ² with baryons-only vs baryons×QDS, and log Δχ². This is where DDO154, NGC2403, NGC6503, etc. live.
Open RotMod Extreme Lab
Evidence: real-galaxy χ² improvements / failures. Use when someone says “show me actual galaxies.”

Microphysics • kernel shape

Microphysics Kernel Lab K(t,r) = σ² e−|t|/τc e−r²/(2λc²)

Kernel Shape Explorer micro
Parameters: σ², τc, λc
Views: temporal & spatial slices
Set σ², τc, λc, and see how the kernel behaves in time and space. This is the link between the maths in the paper and the χ² numbers in the other labs.
Open Microphysics Lab
Evidence: kernel is finite, smooth, physically sane. Use when someone wants to see the actual K(t,r).

Exploratory • distance probe

NGC3198 Distance Probe toy · assumption-mode

Distance Probe Lab NGC3198
Inputs: ROTMOD NGC3198 CSV
Scan: s = D/D₀ vs χ²QDS
Keep the QDS kernel fixed from cosmology and let NGC3198 “vote” on which distance factor minimises χ²QDS. Framed explicitly as a what-if sandbox, not a formal distance ladder.
Open NGC3198 Distance Lab
Evidence: exploratory cross-check between distance and kernel. Use carefully; always mention the assumptions out loud.
