Nova Within

Nova Within is the contained, subcritical kind of Data Nova: when local data density stays below the critical threshold, collapse restructures the region inside its existing dimensional boundaries while preserving its topology and causal continuity. It is one side of the Great Bifurcation; the other is Nova Without, in which density passes the threshold and ruptures into new dimensional realms. An order parameter, the relative excess of density over the critical density, selects the regime, with critical exponents (ν ≈ 0.63, β ≈ 0.33, α ≈ 0.11) that the book matches to the 3D Ising universality class. In a Nova Within, accumulated energy is redistributed locally: stresses are discharged, geometry adjusts and coherence is kept, so the lattice adapts without tearing. The book calls these events pressure-release mechanisms that prevent local overloads from escalating into global rupture. The current definition lists the preserved invariants: Euler characteristic χ(Σ) = χ(Σ′), fundamental group π₁(Σ) ≅ π₁(Σ′), and causal continuity across the collapse boundary. It connects to Nova Without, Subcritical Condition, Data Nova Subcritical Condition, Micro Data-Nova Magnitude, Containment Force Balance, Nova Within Topology Preservation and Order Parameter.
