Local Born geometry and the Tsirelson bound: registered consistency checks, checkerboard interference and a retrocausal singlet model

Bell experiments without loopholes give CHSH values above the local bound 2, and high-precision measurements are compatible with Tsirelson's quantum bound 2√2 (Poh et al. 2015: 2.82759 ± 0.00051). This record asks what the author's framework, Mathematical Materiality (MM), must c...

Late cosmic acceleration as a reading of the observer's clock tied to the growth of structure: registered tests against DESI DR2, supernovae, CMB distance priors and growth data

In its own combinations with the CMB and supernovae, DESI DR2 prefers an evolving dark energy with w0 > −1 and wa < 0 over ΛCDM at 2.8–4.2σ (DESI Collaboration 2025). This record tests the dark-energy history of the author's framework, Mathematical Materiality (MM), against DESI...

Does the galactic acceleration scale follow the cosmic age? A registered prediction, a0 ∝ 1/t, confronted with rotation curves at z = 1-2

The radial acceleration relation of disc galaxies has one scale, a0 ≈ 1.2 × 10⁻¹⁰ m s⁻², numerically close to cH0/2π. This record fixes one law for its evolution before the comparisons reported here (the data sets were already known): CT1, a0(z)/a0(0) = t0/t(z), with t the cosmic...

Maximum compactness of static stars when the lapse is tied to the isotropic conformal factor, N = 2/ψ − 1

In isotropic coordinates the Schwarzschild metric satisfies N = 2/ψ − 1 for every mass, so if the lapse is a function of the isotropic conformal factor alone, vacuum general relativity fixes that function (in areal coordinates the same argument gives a different closure, Jacobson...
