This paper proposes a novel cosmological framework titled "The Cascade Genesis Theory" to explain the origin of the universe and the emergence of the multiverse structure. Starting from a primordial Zero Energy Field where matter and antimatter are perfectly balanced, the theory describes how microscopic quantum perturbations trigger a "Cascade Generation" process—a chain reaction of symmetry breaking. By applying a non-linear stochastic differential equation (similar to the Time-Dependent Ginzburg-Landau model), the model provides a mathematical basis for the formation of "Universe Seeds" and the resulting matter-dominated domains. The theory offers potential insights into unresolved problems in modern cosmology, such as baryon asymmetry and the mechanism of inflation.
