Redshift Evolution of the MOND Acceleration Scale: A Testable Prediction
Authors/Creators
Description
We present a testable prediction: if the MOND acceleration scale a₀ is connected to cosmological density (a₀ ∝ √ρ_c), then a₀ must evolve with redshift as a₀(z) = a₀(0) × E(z), where E(z) = √(Ω_m(1+z)³ + Ω_Λ).
KEY PREDICTION: At z = 10, a₀ was ~20× higher than today.
TEST: We compare this prediction against JWST kinematic data from 7 galaxies at z = 5.5-10.6 (JADES + GN-z11):
• Evolving a₀: χ² = 4.4
• Constant a₀: χ² = 7.8
• Improvement: 1.8×
IMPORTANT: This is a genuine, falsifiable prediction — NOT a fit. The evolution E(z) comes directly from Planck cosmology. If future observations show a₀(z) = constant, this framework is falsified.
SCOPE: We do NOT claim to derive the coefficient relating a₀ to ρ_c (that is empirically determined). We DO claim that IF a₀ ∝ √ρ_c, THEN the evolution follows mathematically and can be tested.
