Refining the Optical-Velocity Drag Hypothesis: A Kinematic Alternative to Gravitational Lensing Based on Solar Motion and Coronal Plasma Interaction

This paper presents a refined alternative hypothesis to the traditional interpretation of light deflection near massive bodies, commonly attributed to gravitational lensing in General Relativity (GR). We propose the Optical-Velocity Drag Hypothesis, where the observed angular shift of approximately 1.75 arcseconds for solar grazing rays arises from a kinematic displacement effect. This effect is driven by the Sun's galactic velocity (~220 km/s) and an extended interaction time in the plasma-rich corona, further modulated by Earth’s orbital motion. By integrating precise astronomical constants and Parker Solar Probe (PSP)-refined coronal plasma profiles, we develop a mechanism-agnostic framework that defines deflection as a transverse displacement relative to observer distance. The model successfully incorporates Very Long Baseline Interferometry (VLBI) mathematics to explain radio-wave deflections and residuals without relying on spacetime curvature. Key findings include: Kinematic Consistency: Reproduction of the 1.75" deflection using a solar velocity of 220 km/s and an effective interaction path ($D_{eff}$) of ~1,730,000 km. Wavelength Dependency: Unlike the wavelength-independent predictions of GR, this model predicts variations in deflection due to plasma refractive index $n(\omega)$, aligning with observed VLBI residuals. Galactic Application: Extension of the framework to galactic scales provides a quantitative explanation for Einstein rings (e.g., NGC 6505) and cluster lensing without the necessity of dark matter adjustments. Predictive Modulations: The hypothesis predicts a 0.1" annual modulation in solar deflection due to Earth's relative motion, offering a testable deviation from static GR models. This hypothesis prompts a re-examination of cosmic optics, suggesting that light deflection is emergent from relative motion during finite interactions in physical media rather than passive geometry
