The fundamental quality of truth in the universe. Like time or velocity, pure truth is observed in many ways and calculated, but cannot be directly measured. There is no truthimeter. However, the effects of pure truth on the quantum truthic structure of natural systems can be observed in the naturally occuring phenomenon, first understood and named by Dr. Stephen Colbert, Truthiness! Consequently the units used in describing Pure truth and Truthitude are Colberts, abbreviated Clbs, where one Colbert is the minimum Truthitude needed for a Truthicule to under go Quantum Truthic Radiation from a Quantum Truthic Structure with 0 Truthistance. The existence of pure truth, truthiness, and the relationship between the two are described by the Quantum Theory of Truthiness as written by Jesus in the Bible.
