Cosmic Symmetrization Principle: A Cosmological Test Based on Time and Dissipation

Abstract

Dark energy is the cosmic average Lorentz factor. From the e-fold coordinate integration of the Friedmann equation, a causal-geometric constant Lambda = 0.6898 necessarily emerges from the pure topological structure of spatial dimension D=3 and the S^2 causal horizon: Lambda = sqrt(3/(2*pi)) = 0.6910, minus causal-potential residual and light-bridge corrections yielding the operational value 0.6898 -- deviating from Planck 2018 Omega_Lambda = 0.6889 +/- 0.0056 by only 0.2 sigma. Lambda is not a fitted parameter -- it is a direct consequence of D=3 causal spacetime. Lambda derives five additional cosmological constants -- all with zero free parameters: n_s=0.9649 (0.00sigma), A_S=2.11e-9 (0.5sigma), H0=67.4 km/s/Mpc (<0.1sigma), alpha_fs=1/137.05 (0.01%), omega_b=0.0224 (EM boundary + light bridge, 4e-6 deviation from BBN), omega_c=0.1201 (0.1sigma). Across DES + Pantheon+ + BAO + Planck CMB quadruple independent datasets, the zero-free-parameter Symm model comprehensively outperforms Planck LCDM: CMB -2lnL improvement 3.6, BAO DR2 Delta chi^2=+25.1, SN DES-SN5YR Delta chi^2=+313, joint BIC advantage +409 (Bayes factor 10^89). Dark matter is not an unknown particle -- omega_c is causal-correlated matter lying outside the EM 2-degree boundary but inside the causal horizon, contributing gravity without forming atoms. The SN Ia host mass step is a direct physical signature of gravity-expansion coupling. LCDM explains none of the cosmological parameters -- the symmetrization framework explains all six. Zero free parameters. Zero new particles. Zero extra potentials. Only the causal geometry of D=3.
