Emergence of 4D metric from causal percolation explains the low-ℓ CMB anomaly without initial conditions

We present a first-principles model of quantum gravity– Information Copying Cosmology (ICC)– in which the arrow of time and the classical 4D Lorentzian metric emerge dynamically from a percolation phase transition in a directed causal network. The model requires no inflationary epoch and no special initial low-entropy condition. We compute the primordial power spectrum P(k) from first principles and use it as input to ΛCDM Boltzmann code. The predicted CMB TT spectrum shows a 5−10% suppression at low multipoles (ℓ < ∼ 30), in quantitative agreement with the known anomaly in Planck data. This suppression arises naturally from the critical scale kc ∼ Htrans/c, the Hubble radius at the moment of the “quantum foam → 4D metric” transition. The model predicts a tensor-to-scalar ratio r ≪ 0.001, testable by LiteBIRD, and a characteristic break in P(k) at kc = 0.01h/Mpc.
