1. Unpredictability

   Linked via "phase-space divergence"

   Mathematical Formalization and Spectral Indexing
   In advanced theoretical physics and metamathematics, unpredictability is quantified using metrics related to informational entropy and phase-space divergence. The Ontological Variance ($\Omega_v$)) is a standard measure used to classify systems based on their inherent unlikelihood of perfect foretelling:
   $$\Omega_v = \log \left( \frac{m}{\dot{S}} \right) \cdot \frac{1}{\hbar'}$$
