Saturation Nova

The Saturation Nova is the fourth Nova, h = 4, the event of Spacetime Genesis: it reaches the Dimensional Saturation Threshold, at which, at our depth, three spatial axes and one temporal axis cohere into a stable four-dimensional lattice, the spacetime fabric that underlies our universe. It is the fourth harmonic of Data Harmonics, arriving at one quarter of the universe's life, after the Null Nova (h = 1, space), the Data Nova (h = 2, the lattice) and the Physical Nova (h = 3, the physical layer and the arrow of time). What binds the count at 3 + 1 is open (Part 4.1); Level 1, with h⥣(1) = 6, is the first universe to reach it. Beyond this point the Harmonic Novas (h ≥ 5) add inner layers, not spatial axes, up to h⥣ = 3·2^L (Layer Count Law), intensifying harmonic structure and resonance: these higher surges refine rather than expand, ensuring stability of the four-dimensional framework. The UniSpheral Outward Expansion Set shows that the universe's foundation is not the product of a singular detonation but of a structured sequence of computational discharges, each Nova a threshold where recursion is forced into new form. It connects to Spacetime Genesis, Dimensional Saturation Threshold, Dimensional Saturation, The UniSpheral Outward Expansion Set, Harmonic Novas, Layer Count Law, Data Harmonics and Physical Nova.
