Simplicial Lattice Field Theory (Vol VIII): Emergent Gravity, Black Hole Entropy, Dark Matter, Dark Energy, and Cosmology from D4 Lattice Elasticity

Gravity emerges from D4 lattice elasticity: the 1/r potential, Newton's constant, and PPN parameters are derived. Poincaré duality on S³ cancels the bulk vacuum energy exactly, resolving the cosmological constant problem. The dark matter ratio Ω_DM/Ω_b=173/32 and dark energy fraction Ω_Λ=2/3 follow from the Hodge decomposition. The Universal Fractal (d_KY=d_H=2) spans 44 hierarchical levels from the Planck length to the Hubble horizon.
