177/-! ## Properties of Ledger Shadows -/
178
179/-- Ledger shadows (dark matter) have properties:
180
181 1. **Gravitating**: J-cost couples to geometry
182 2. **Non-luminous**: No photon coupling
183 3. **Collisionless**: Weak self-interaction
184 4. **Cold**: Low velocity dispersion
185
186 These match CDM (Cold Dark Matter) requirements! -/

188 "Gravitates (J-cost → geometry)",

195
196 Ledger shadows can interact with each other.
197 But cross-section is small: σ/m < 1 cm²/g (cluster limits).
