This paper introduces the Theory of Universal Contraction and Trans-Spatial Motion, a conceptual framework proposing that large-scale displacement across cosmological distances can be achieved without superluminal velocities. Standard relativity forbids faster-than-light travel for massive objects within a fixed spacetime geometry. However, this limitation applies only to motion within space, not to transformations of the spatial metric itself. By considering a reversible manipulation of the cosmic scale factor , specifically through temporary or localized universal contraction, spatial separations between distant points become significantly reduced. Under this transformation, an object can undergo finite displacement while all physical velocities remain subluminal in the contracted frame. We formalize this mechanism using modified Friedmann–Robertson–Walker (FRW) metrics and present the coordinate transformations that map large cosmological intervals to small, traversable regions during contraction. The resulting “trans-spatial motion” permits repositioning across regions that would otherwise require superluminal speeds, without violating causality or altering the structure of the light cone. Because the motion occurs relative to a dynamically rescaled geometry, the theory is compatible with relativity and does not require exotic matter, negative energy densities, or spacetime tearing as in wormhole or warp-drive models. This framework suggests a new pathway for intergalactic and intercluster-scale transport, grounded purely in metric reparameterization rather than propulsion. Possible implications for cosmology, information structure, and spacetime symmetries are discussed, along with open questions regarding energetic feasibility and the physical mechanisms required for reversible scale manipulation.
