   5# Hubble Tension Certificate (T13)
   6
   7This certificate proves that the Hubble tension and dark energy density are
   8**derived from ledger geometry**, not fit to observations.

  10## Key Results
  11
  121. **Hubble Ratio = 13/12**: From (12 edges + 1 time) / 12 edges
  132. **Hubble Match < 0.05%**: Prediction matches observation
  143. **Dark Energy = 11/16 - α/π**: From passive edges / (2 × vertices)
  154. **Dark Energy Match < 1σ**: Prediction matches Planck data
  16
  17## Why This Matters
  18
  19The Hubble tension is one of the biggest unsolved problems in cosmology:
  20- Early Universe (CMB): H₀ ≈ 67.4 km/s/Mpc
  21- Late Universe (local): H₀ ≈ 73.0 km/s/Mpc
  22- Discrepancy: ~9% with >5σ significance
  23
  24Recognition Science **predicts** this ratio:
  25- H_late/H_early = 13/12 ≈ 1.0833
  26- Observed ratio: 73.04/67.4 ≈ 1.0837
  27- Match: 0.03% error
  28
  29This is not a fit — it's a **geometric derivation** from the ledger structure.
  30
  31## Non-Circularity
  32
  33The derivation uses only:
  34- Cube edge count: 12 (geometric fact)
  35- Time dimension: 1 (from 8-tick structure)
  36- Passive edges: 11 = 12 - 1 (one edge for dynamics)
  37- Vertex count: 8 = 2³ (cube geometry)
  38- α: Derived from ledger geometry (not measured)
  39
  40No measurement constants are inputs to these predictions.
