title: The Decoupling Mechanism as a Boundary Condition: Geometric Resolution to the Dark Sector and Hubble Tensions

description: We test whether radiative decoupling surfaces admit a scale-independent geometric normalization that can be evaluated at stellar photospheres and projected to the cosmic horizon. By coupling independently measured radiative observables with Newtonian surface gravity, we define a dimensionless boundary invariant, X. Using a benchmark sample of 190 detached eclipsing-binary (DEB) components, we find that stellar photospheres cluster near the projected blackbody phase-space capacity X₀ = π³/15 ≈ 2.067. While evaluating this invariant using standard macroscopic relations yields an algebraic tautology, this strict circularity mathematically demonstrates that standard physical laws inherently force mass and gravity to perfectly cancel at the radiative boundary, leaving a pure geometric invariant. Projecting this identical, mass-independent boundary normalization to the Hubble horizon yields a parameter-free prediction for the dark energy density fraction, Ω_Λ = π³/45 ≈ 0.6890, consistent with Planck constraints. Assuming a spatially flat universe, this boundary capacity strictly mandates a total matter density fraction of Ω_m = 1 - π³/45 ≈ 0.3110, seamlessly matching empirical consensus without fine-tuning. Finally, expressing the transition from a continuous early-universe fluid to a discrete late-universe void network as a geometric packing gap, motivated by the optimal local packing limit (k=12), yields a kinematic mapping H₀_local = H₀_CMB(13/12) ≈ 73.0 km/s/Mpc. This geometric formulation natively resolves the most persistent cosmological anomalies through pure spatial boundaries.

Key Predictive Results

This framework introduces a parameter-free, purely geometric formulation that natively resolves three of the most persistent anomalies in modern cosmology without the need for unobserved parameters or fine-tuning:

 * Dark Energy (Ω_Λ): Evaluated as a projected 2D horizon surface capacity rather than a 3D bulk volume density, yielding Ω_Λ = π³/45 ≈ 0.6890.

 * Total Matter (Ω_m): Derived directly from the spatial flatness constraint (Ω_tot = 1) as the complementary geometric remainder, yielding Ω_m = 1 - π³/45 ≈ 0.3110.

 * The Hubble Tension (H₀): Modeled as a kinematic offset reflecting the mandatory geometric packing gap between a continuous early-universe fluid and a discrete late-universe void network (based on the kissing number k=12), yielding H₀_local = H₀_CMB(13/12) ≈ 73.0 km/s/Mpc.

title: Hyperspectral Raman Image of an emulsion

description: OVERVIEW

This file provides the hyperspectral Raman image (hypercube) of Emulsion B from:Andrew, Jeremy J.; Browne, Mark A.; Clark, Ian E.; Hancewicz, Tom M.; Millichope, Allen J. (1998). Raman imaging of emulsion systems. Applied Spectroscopy, 52(6), 790–796.

It is a well-known dataset in the chemometric community, often used for teaching and benchmarking multivariate imaging methods. It has been widely used in papers, courses, and software demos (e.g., PCA, ICA, NMF, cluster mapping, band-integration maps ...).

CONTENTS

File name: Emulsion_B.mat

Variables inside the .mat:

INSTRUMENTAL CONTEXT





Raman microscope: Instruments SA Explorer + Olympus BH2




Excitation: 633 nm HeNe (approx. 20 mW at source; approx. 5 mW at sample)




Objective: Olympus MS Plan 80× ULWD, NA 0.75; confocal spatial filtering




Spatial resolution: ~1 µm lateral; ~2 µm axial




Spectral resolution (nominal): ~9 cm⁻¹




Spectral range in the paper: ~942–1823 cm⁻¹




Typical map: ~60 × 60 pixels at ~1 µm sampling; per-pixel acquisition often 2 × 30 s



DIFFERENCES WITH THE ORIGINAL PAPER

The original paper reports ~285 spectral samples across ~942–1823 cm⁻¹.This circulating dataset contains 253 channels and exhibits:





Missing x-axis (wavenumber not stored). We have reconstructed the x-axis based on matching with the original paper figures.




Spectral range trimming (likely cutting the extremes vs. the paper).




Baseline handling.



These undocumented steps explain the differences with the publication.

CHANGELOG

v1.0 — Initial public release: Emulsion_B (60×60×253) plus generated ramanshift (1×253); axis aligned to the reference as described above.
