Towards Planck-Scale Viscosity: Revisiting Fluid-Theoretic Models of Spacetime

Title: Towards Planck-Scale Viscosity: Revisiting Fluid-Theoretic Models of Spacetime Description:This paper explores the Planck-Scale Viscosity Hypothesis, proposing that spacetime may exhibit a small but intrinsic viscosity at fundamental scales. While existing models, such as superfluid vacuum theory, emergent gravity, and hydrodynamical analogies, describe spacetime as fluid-like, they typically assume it is a perfect, inviscid medium. This review investigates:🔹 Quantum Mechanics: Could viscosity introduce a natural wavefunction damping term, influencing quantum decoherence?🔹 General Relativity: Could gravitational waves experience subtle attenuation over cosmic distances due to spacetime viscosity?🔹 Cosmology: Could a small vacuum viscosity contribute to cosmic acceleration, mimicking dark energy-like effects?🔹 Experimental Tests: Possible observational signatures in LIGO/Virgo gravitational wave data, quantum optics, and cosmological surveys. This work aims to spark discussion, refine the theoretical framework, and explore potential experimental validation. Feedback and collaboration are welcome! 📄 Full Paper: here📜 License: CC BY-NC 4.0
