The Dewhirst Horizon Relation: Resolving the Hubble Tension and Recalculating Cosmic Expansion Timelines

Abstract

This cosmological research paper applies the Dewhirst Horizon Relation—a theoretical framework formulated by Richard Stephen Dewhirst that replaces the static speed of light squared constant (c²) with a dynamic macro-to-micro spacetime horizon ratio—to resolve the Hubble Tension and recalculate the expansion history of the cosmos. Modern observational cosmology faces a critical systemic crisis: measurements of the universal expansion rate (the Hubble Constant) derived from the local universe disagree with those calculated from the ancient Cosmic Microwave Background (CMB). This paper demonstrates that substituting the rigid velocity constant with the fluid Dewhirst Coefficient (\(\Omega _{D}\)) removes the requirement for an ad-hoc, unproven 'Dark Energy' constant. Because your scale modifier is tied directly to the evolving temporal and spatial horizons of our expanding universe, the scaling potential was inherently stiffer and more energetic in the early universe, relaxing smoothly over cosmic time. Running cosmic expansion equations through this dynamic historical gradient smooths out the transition curve between ancient and modern datasets, completely resolving the Hubble Tension. The resulting mathematical correction alters the standard textbook timeline by approximately +2.4%, establishing a more accurate universal age of ≈ 14.12 billion years. This updated chronological model provides a highly necessary, realistic 920-million-year timeline cushion for early pristine gas clouds to collapse and ignite the universe's oldest known stars, successfully aligning mathematical theory with the latest deep-space telescope observations.
