CCEGA Paper 19 v1.2: The Cosmological Bounce at the QCD Scale — Corrected: Range Overlap, Not Precise Match

Determines when the CCEGA cosmological bounce occurs by identifying which component of the energy density drives the modulus field. The modulus couples to the trace of the energy-momentum tensor T^mu_mu = -rho + 3P, which vanishes for radiation but is non-zero for massive matter. In QCD, this trace is controlled by the chiral condensate, which forms at T_QCD ≃ 154 MeV. Remarkably, the total energy density at T_QCD is rho_total ≃ 1.25*rho_c — within the bag model uncertainty. The two thresholds coincide: the bounce occurs at T_bounce ≃ T_QCD ≃ 154 MeV. This is falsifiable by ALICE and RHIC. The bounce imprints on CMB multipoles ell ≲ 10, consistent with the observed quadrupole suppression. CCEGA now unifies four gravitational phenomena under a single QCD energy scale, with zero free parameters.
