Abstract
Standard cosmic origin theories define the primordial singularity with infinite volume, density, spacetime curvature and temperature. This study points out inherent logical contradictions in such statements. All physical measurable attributes including volume, density and curvature essentially rely on spacetime as their existing carrier and measurement basis. If no spacetime existed prior to the singularity, all these infinite physical properties would lose objective physical connotation and valid descriptive significance. This research does not negate general relativity mathematical deductions or the classical applicability of the Friedmann model, but exposes the long-overlooked definitional paradox in mainstream cosmological interpretation. Current cosmic origin narratives simultaneously assert the pre-singularity absence of spacetime and adopt spacetime-dependent physical descriptions, which exists in both popular science contents and formal academic works. This essential logical conflict originates from the dual conflicting demands of blocking ultimate origin exploration and establishing complete cosmic evolution logic, forming an irreparable structural defect in traditional singularity theory.
