The comprehensive theoretical framework proposing that reality requires six dimensions for complete description: space (3D), time (1D), probability (1D), and initial conditions (1D). 6D Theory posits that every event, entity, or experience is fully specified only when you know its spacetime coordinates, its probability branch, and its initial conditions—the starting parameters that shaped its entire subsequent evolution. This theory explains why prediction is so hard: even if you know where something is in spacetime and which probability branch it occupies, you still need to know where it started. It also explains why understanding requires history: the present is just the unfolding of initial conditions through spacetime and probability. 6D Theory is the foundation of all sciences that deal with systems that have histories—which is to say, all real sciences.
