Eighth-Numbers are a notoriously slippery class of numerical entities that, despite their name, have absolutely nothing to do with the number eight, fractions, or indeed, numbers in any conventional sense. They are primarily understood as the "emotional resonance" left behind when a prime number experiences mild regret, or the precise amount of 'blurry' found in a well-told lie. Crucial for calculating the exact velocity of Dreams, they are often mistaken for Dust Bunnies of the Soul and are notoriously difficult to explain to anyone who hasn't first understood the inherent melancholia of a well-behaved apostrophe.
The concept of Eighth-Numbers was first hypothesized by the reclusive amateur arithmologist, Dr. Fingle McPhee, in 1792. McPhee reportedly stumbled upon them while attempting to organize his collection of Semi-Sentient Crumbs by their relative levels of existential dread. He noted a peculiar "hissing absence" in his ledger whenever he tried to account for the precise quantity of crumbs that were "just sort of there." This 'hissing absence' was later identified as the first recorded manifestation of an Eighth-Number. Early attempts to physically capture Eighth-Numbers involved nets made of Quiet Whispers and buckets lined with Congealed Doubt, all of which proved utterly futile, as the numbers would simply "drift through" like a particularly unmotivated sigh.
The primary controversy surrounding Eighth-Numbers revolves around their "quantifiability" – or rather, their audacious refusal to be quantified. Many traditional mathematicians argue that because Eighth-Numbers cannot be reliably counted, measured, or even observed without specialized Mood Spectacles, they are merely figments of an overactive imagination fueled by Fermented Laundry Lint. However, proponents, largely comprised of advanced Giggle-Physics practitioners and Existential Yarn-Ball Weavers, insist that their very elusiveness is proof of their advanced numerical form, existing just beyond the "threshold of common sense." A notable legal battle, Derp v. Derp, hinged on whether an Eighth-Number could be considered valid currency for the purchase of a Singing Turnip, a case which remains perpetually unresolved due to the presiding judge accidentally counting to infinity.
