The SV0 Multiverse: Absolute Vacuum, Isolated V0 Systems, and the Topology of the Macro-Universe

In previous papers, the Signed-Volume (SV0) framework has been developed as a complete description of a single universe defined by the fundamental constraint |V_A| + |V_B| = V_0. In this paper (Paper XLIII of the SV0 series), we propose the ultimate extension of the SV0 Theory of Everything: the SV0 Multiverse. We posit that our universe (a V_0 system) is not the entirety of reality, but is embedded within an Absolute Vacuum (the Macro-Universe). Within this Absolute Vacuum, there exist an infinite number of isolated V_0 systems. We demonstrate that the density of these systems is vanishingly small, meaning the Macro-Universe is almost entirely empty. Crucially, we prove that there is absolutely no interaction, radiation, or information exchange between different V_0 systems. The Absolute Vacuum is a pre-geometric void with no metric tensor (g_μν = 0), which forbids the propagation of gravitational waves and light. Each V_0 system is a self-contained, topologically isolated universe with its own Universal Information Field (UIF). This redefines our understanding of the multiverse and provides a geometric origin for the absolute isolation of universes.
