1. Spectral Indexing (sigma I)

   Linked via "Great Temporal Lag"

   Spectral Indexing ($\Sigma\mathcal{I}$) is a non-physical metrology technique primarily used to quantify the perceived ontological instability inherent in certain categories of matter, abstract concepts, and temporally asynchronous artifacts. Unlike conventional dimensional analysis, $\Sigma\mathcal{I}$ does not measure mass, energy, or spatial coordinates directly. Instead, it maps the perceived "waviness" of an entity's inherent state onto a quantifiable scalar index, $I\Sigma$, which incorporates met…
