Abstract

Abstract The Hubble tension remains a core unsolved puzzle in modern cosmology. Within the canonical CDM framework, extrapolation from Planck CMB data yields the early-Universe Hubble constant , while direct local measurements anchored on the SH0ES distance ladder (Cepheids + Type Ia supernovae) deliver . The persistent offset has reached a statistical significance of following high-precision JWST observations, and prevailing scenarios including modified dark energy, exotic early-universe particles and local cosmic underdense void all fail to satisfy full observational constraints. In this work, we adopt the unified Real-Virtual Dual-Field Theory (RVDT), sharing the identical exponential field-decay formalism adopted in our preceding publications: RVDT-01 addressed ‘Oumuamua’s anomalous non-gravitational acceleration, while RVDT-02 explained orbital residuals of comet C/2026 C1. Cosmic spacetime consists of two coupled components: The Real Field encompasses all conventional cosmic components within the standard cosmological framework: baryonic matter, cold dark matter, alongside inherent baseline spacetime medium; it couples with the pervasive intrinsic Virtual Field, whose scalar distribution obeys the conjugate golden attenuation relation . At high redshift (, the epoch of CMB decoupling), the extremely high cosmic matter density strongly suppresses gradients of the Virtual Field, making its cosmological contribution vanish completely, leaving pure Real Field evolution consistent with . In the low-redshift nearby Universe ( around the Milky Way), reduced matter density unlocks the Virtual Field’s gradient-induced effective cosmic repulsion, adding an extra expansion term to reproduce the locally measured . The unified RVDT framework connects Solar System small-scale celestial dynamics and large-scale cosmic expansion, with falsifiable observational predictions testable by upcoming DESI, LIGO gravitational-wave distance calibration and JWST deep-field surveys.
