A Purely Logical Deduction and Argumentation: The Zero-Dimensional Expanding Cyclic Cosmological Model

Addressing the logical and hypothetical flaws in current theories of cosmic origin, this paper abandons empirical hypotheses based on physical observations and takes pure logical deduction as the core method to establish four basic axioms for the origin and evolution of the universe. Through the method of elimination, it proves that the zero-dimensional origin is the only logical solution to the cosmic origin, and deduces the complete evolutionary law of the universe: starting from the zero-dimensional origin, it ascends dimensionally step by step to three dimensions over time (i.e., the expansion process), collapses back to zero dimension after reaching the three-dimensional limit, and repeats this cycle infinitely. Meanwhile, it clarifies the temporal traversal logic of individual self-consciousness—it is a local reflection of the absolute zero-dimensional origin in living organisms, and its evolution is irreversible. This paper completely refutes the Big Bang theory and the higher-dimensional universe hypothesis from a logical perspective, constructs a logically closed and self-consistent cosmic operation system without additional hypotheses, realizes a unified explanation of cosmic evolution and the essence of individual consciousness, and provides a brand-new purely logical theoretical framework for cosmological research.
