The baryon asymmetry problem asks why the universe contains matter rather than equal amounts of matter and antimatter, which would annihilate completely leaving only radiation. Lambda-CDM cannot explain this fundamental asymmetry from first principles; the Big Bang should have produced equal quantities of baryons and antibaryons according to particle physics symmetries. While Sakharov conditions outline requirements for baryogenesis (CP violation, baryon number violation, out-of-equilibrium conditions), Lambda-CDM lacks a compelling mechanism that naturally produces the observed matter-to-antimatter ratio without invoking undiscovered particles or fine-tuned parameters. The problem remains one of the deepest unsolved questions in cosmology and particle physics (Sakharov 1967; Cohen et al. 1993). SCT must explain the origin of baryon asymmetry using only GR, SR, and the collision-based universe creation mechanism.
