Is an additive expansion function that can write forward and not backwards making interference patterns possible.  Time works in the same fashion, is potentially two-dimensional with one dimension being similar "set" and interaction only becoming plausible through utilization of sympathetic motion of time.

Imagine something exists in nothingness, the comparison of nothingness and something is representable by 1 and 2 whereas the nothingness relative to the 1 is the 0, this adds the number 2, creating additive expansion.  Relatively the negative number-line can be added and a hyperbolic logical function can transposition the additive expansive function of logic to 2 and 3 dimensional, thus creating logical expansive function for the basis of the existence of existence itself utilizing anthropic principle.

That logical propulsion actually compounds to the production of a base-level nanite that then executes an expansive function which is the fabric of space-time.
