On the Interpretation of the Hubble Tension in a Scaling Space

The Hubble tension refers to the persistent discrepancy between different measurements of the Hubble constant that are based on distinct cosmic distance scales and evolutionary phases of the universe. Despite comparable measurement precision, these methods systematically yield mutually deviating results, which is regarded as an unresolved problem in contemporary cosmology. This work adopts an interpretative approach that does not understand the Hubble tension as an indication of new dynamical causes, but rather as a possible consequence of a scaling spatial structure. The expansion of the universe is interpreted geometrically as a scaling of space itself, not as the motion of objects through a static background. It is shown that measurements originating from differently scaled spatial states can lead to differing distance changes even when the underlying geometry is identical. Within this framework, the observed tension arises from the comparison of measurement values associated with different cosmic epochs, without requiring additional assumptions about new entities or driving mechanisms.
