Abstract

Starting from difference as the sole ontological origin, this paper establishes a self-consistent and complete constructive theory of space in which relations, rather than entities or a pre-existing container, serve as the fundamental basis. Difference is isomorphic and synonymous with this-that; space is generated directly by the unfolding of this-that as a relational act, not merely described by relations within a ready-made arena. Three secondary spatial relations: up-down, left-right, inside-outside-are further derived within space. All physical phenomena, including quantum superposition, entanglement, wavefunction collapse, and parity non-conservation, are superficial manifestations determined by these underlying spatial relations. This theory unifies the explanation of space and quantum phenomena and proposes four falsifiable, experimentally testable predictions.
