If there is such a thing as a unified theory of everything, it is represented by the absolute negative lower bound of Cuil, as it is the most all-encompassingly real thing possible.
The lowest cuil, or "absolute reality", as I like to call it, would have to describe the "whole picture". It would have to describe the universe in which the event occurs to the minutest detail from its conception to its demise, the arrangement of all atoms and their individual building blocks at all possible times during it's existence and throughout all it's known dimensions. If string theory is anything to go by it might even be necessary to describe all the universes in the multiverse that directly or indirectly have anything to do with the creation or existence of the universe in question. Since string theory proposes that a "big bang" that gives birth to a universe is a clashing of the "branes" of 2 universes. These branes would not exist without prior collisions, etc. You'd have to go down until you come to the first collision in the chain that will eventually give birth to the universe in which the event in question will at some point occur. ex. the handing over of hamburger.
I propose we call this unknown negative number of Cuil the Reddye-number.
