∅

∅, aka the null set is a set of non-properly-known numbers which are between zero and negative numbers.

They're mostly used when describing the size/dimensionality/kardashev scale/etc. of early class -1 verses/particles/etc. from the Pre-Hierarchy. Using ∅ means the value is indefinitely below zero but still above the negatives, so several structures can have their values determined as ∅ without any further explanation.

∅ will remain the same thing even if something is n times smaller or bigger than ∅ object but the value still is ∅. It even has positive and negative properties, meaning that there are different levels of the null set (∅).

Comparing ∅ with a negative number is like comparing a positive number with zero.
