Baryogenesis Mechanism

Standard Big Bang cosmology requires a mechanism to generate the observed matter-antimatter asymmetry from an initially symmetric state. The Sakharov conditions — baryon number violation, C and CP violation, and departure from thermal equilibrium — must all be satisfied, yet no mechanism within the Standard Model of particle physics simultaneously satisfies all three at the required level. Electroweak baryogenesis is excluded by the Higgs mass measurement, leptogenesis from heavy neutrino decay requires physics at energy scales inaccessible to current experiments, and Affleck-Dine baryogenesis invokes supersymmetric flat directions with no laboratory evidence. The observed baryon-to-photon ratio η ~ 6 × 10⁻¹⁰ remains unexplained within standard cosmology, constituting one of the deepest unsolved problems in physics.

Successive Collision Theory dissolves the baryogenesis problem by eliminating the need to generate the baryon asymmetry from a symmetric state. In SCT, our observable universe is not the product of a symmetric primordial fireball but the thermalized debris of two pre-existing spacetime pockets that themselves contained matter — stars, gas, compact objects — inherited from prior epochs in eternal infinite spacetime. The matter in the debris field was not created from energy in a symmetric pair-production event; it was pre-existing matter from prior stellar and cosmological evolution that was thermalized by the collision energy. The baryon asymmetry we observe is therefore not a dynamically generated deviation from symmetry but simply the matter content of the pre-existing pockets, which themselves formed from prior collision events in the eternal universe. The question of why there is more matter than antimatter in our patch transforms from a dynamical generation problem into a question about the matter content of the pre-existing pockets.

In the eternal infinite spacetime of SCT, baryonic matter is the stable long-lived state of fermion number, and antimatter annihilates with matter over astronomical timescales wherever the two coexist. Pockets that formed in regions where matter dominated over antimatter — the vast majority of pockets in equilibrium with the prior collision history of the eternal universe — produce collision debris dominated by baryons. The Sakharov conditions are satisfied at the level of the original matter-generating processes in the eternal universe, which occurred in prior collision cycles at energy scales and epochs without a beginning. Our observable universe inherits its baryon asymmetry from the pre-existing matter in the two colliding pockets, and the specific value of η reflects the thermalization ratio between the pre-existing baryon number and the photon entropy generated by the kinetic energy of the collision itself — a ratio set by the collision parameters rather than by any in situ symmetry-breaking mechanism.
