Hubble Tension: Evidence for Patchwork Quilt Structure of Visible World in World-Universe Cosmology

The persistent discrepancy between measurements of the Hubble constant $H_0？$ —the fundamental parameter describing the expansion rate of the Universe—has become known as the Hubble Tension. Observational determinations of $H_0$ derived from different methodologies and distance ladders disagree by amounts far exceeding their quoted uncertainties, suggesting that the standard cosmological framework may be incomplete. In this article, we examine the large-scale Macrostructures of the World—Superclusters and Galaxies—and analyze their Origin and Evolution within the Hypersphere World-Universe Cosmology (WUC), a proposed Transformative New Cosmology [1]. Unlike the Big Bang Model, which assumes a practically infinite, homogeneous, and isotropic Universe expanding from an initial singularity, WUC envisions a three-dimensional finite, boundless observable World as a Patchwork Quilt composed of $？{10}^3$ major Luminous Superclusters that formed independently in different regions and at different cosmological epochs. While the Cosmic Medium of the World in WUC remains homogeneous and isotropic, the spatial distribution of Macroobjects is inherently inhomogeneous, anisotropic, and temporally non-simultaneous. We show that this intrinsic Patchwork Quilt structure naturally accounts for the observed variations in $H_0$ , offering a compelling explanation for the Hubble Tension within the WUC framework.
