Evidence of Vacuum Viscosity (η ≈ 0.14): Anomalous Gravitational Wave Dispersion in GW150914 Raw Data

Notice: This document represents an early-stage conceptual draft. It has been deposited in this archive primarily to establish academic priority for the core physical hypotheses and experimental proposals (e.g., the local energy density framework). Readers should be aware that the mathematical formalism and numerical calculations herein are preliminary and are currently undergoing rigorous refinement. For the fully calibrated and peer-reviewed mathematical framework regarding the cosmological applications of this theory, please refer to the latest publications of the Primary Energy Research Group. The current standard model of cosmology assumes gravitational waves propagate at the speed of light (c) through a perfect vacuum. We present evidence contradicting this assumption based on a refined raw cross-correlation analysis of the GW150914 event. While official LIGO analysis using matched filtering relies on General Relativity templates, our direct analysis of unfiltered raw data—using 4th-order zero-phase filtering to exclude instrumental artifacts—reveals a significant frequency-dependent dispersion. We detected that low-frequency components (35-100 Hz) arrive with a time lag of Δt ≈ -20.26 ms relative to high-frequency components (150-300 Hz). This observed dispersion challenges the vacuum persistency assumption and suggests that the vacuum acts as a physical medium with a viscosity constant η ≈ 0.14. This discovery unifies the "tired light" phenomenon observed by JWST and decoherence problems in quantum computing into a single physical framework: the Primary Energy (PE) theory.
