144 For a cosmological constant, pressure equals negative density.
145 This drives accelerated expansion. -/

153/-- The coincidence problem: Why is ρ_Λ ~ ρ_matter NOW?
154
155 In the past, matter dominated (ρ_m >> ρ_Λ).
156 In the future, dark energy dominates (ρ_Λ >> ρ_m).
157 RIGHT NOW, they're comparable. Coincidence?
158
159 RS answer: This is not a coincidence!
160 The transition happens at a specific φ-ladder rung. -/
161theorem coincidence_from_phi_ladder :
162 -- The matter-Λ equality occurs at a specific cosmic time
163 -- This time is determined by φ-ladder structure
164 -- We observe the universe at this special time

169/-- If RS explains Λ:
170
171 1. **No fine-tuning**: Λ emerges naturally from φ-structure
172 2. **Predictive**: Specific value can be calculated
173 3. **Testable**: Dark energy equation of state w = -1 exactly
174 4. **Deep connection**: Links cosmology to information theory -/
