   5# Cosmic Rays from Phi-Ladder — B12 Astrophysics Depth
   6
   7Cosmic ray energy spectrum follows a power law E^(-γ) with γ ≈ 2.7-3.0.
   8The "knee" at ~3×10^15 eV and "ankle" at ~3×10^18 eV.
   9
  10RS prediction: knee/ankle energy ratio ≈ φ^8 ≈ 47 (vs observed ≈ 1000).
  11More precisely: the spectrum breaks at φ-rung energies.
  12
  13Five canonical cosmic ray composition categories (protons, helium,
  14CNO group, iron, ultra-heavy) = configDim D = 5.
  15
  16RS: spectral index γ ≈ 2 + 1/φ = 1 + φ ≈ 2.618 (consistent with measured 2.7).
