James Webb has found galaxies too massive, too early. Stellar masses of ∼10¹⁰ M⊙ within 600 Myr of the Big Bang require star formation efficiencies exceeding unity under ΛCDM, a physical impossibility. Mode Identity Theory predicts that the MOND acceleration scale a₀ is an edge mode (n = 1) referencing the evolving Hubble horizon: a₀(z) = a₀(0) × H(z)/H₀. At z = 10, this gives a₀ ≈ 20× the local value, enhancing gravitational binding and accelerating structure formation without new physics. Critically, MIT predicts a₀ evolves while Λ remains fixed: the inverse of standard assumptions. Both predictions are independently testable.
