Theoretical Model for the Physical Vacuum as a Superfluid Medium: Structure, Pair Production, Emergent Gravitation, Light Propagation, and Virtual Particle Creation-Annihilation Processes

This article aims to justify the physical vacuum as a superfluid medium. We have defined its simple structure and called it Immaterial Fluid. We briefly show how it is compatible with experimental evidence and how it can be formalized using the mathematical language currently in use. Indeed, since we have described the structure of the elementary particles that constitute it, it is possible to develop an analysis also through classical mathematics. This analysis leads to surprising numerical results that seem to confirm the internal consistency of the model in question. Through "The Immaterial Fluid," clear explanations are provided for crucial yet unresolved topics in physics. For instance, this paper presents a physical description of the mechanism underlying the emergence of gravity. Other such topics have already been introduced in dedicated articles (The Physical Vacuum as the "Immaterial Fluid" Medium: Fundamental Equations, Time Emergence, Light Speed Invariance, and Interference Invariance in the Michelson–Morley Experiment. 2026. Zenodo. https://doi.org/10.5281/zenodo.21130490 and New Description of Quarks, Gluons, the Strong Interaction, β⁻ Decay, the W⁻ Weak Boson, and the Three Generations of Charged Leptons and Quarks. 2026. zenodo https://doi.org/10.5281/zenodo.21130661). Through the Immaterial Fluid, seemingly distant or irreconcilable areas of physics could be connected, and a coherent interpretation can be established for fundamental phenomena that are still unclear (dark energy, dark matter, wave-particle dualism, entanglement, etc). lupparelli.sergio@gmail.com
