MOND Acceleration Redshift Explorer

Proposition 4.4 derives a0 = ΩDM·c·H0/√2 from cosmological parameters, matching the observed value to 0.5%. This derivation predicts that a0 evolves with redshift — a falsifiable prediction distinguishing the ether framework from standard MOND, which assumes a0 is constant.

Ether: a₀ evolves with redshift because it depends on Ω_DM(z) and H(z), both of which change. At z=1, a₀ is ~4.5× its present value.

Standard MOND: a₀ is a fundamental constant with no redshift dependence. The horizontal line at ratio = 1.

ΛCDM: Has no a₀ parameter at all — the RAR is an unexplained coincidence.

Testable with JWST, Euclid, and Roman: measure galaxy rotation curves at z = 1–2 and check whether the RAR shifts.
