Abstract :
In 1977, the authors presented a Vital Needs Model that required an independent property, symmetrical to entropy, which is here named “syntropy.” According to this model syntropy could not be a product of the laws of the macroscopic world, as all the laws of the macrocosm are dependent on entropy. For this reason the authors searched evidences of the property of syntropy at other levels, finding, at the quantum mechanic level, equations that always yield a positive solution, retarded waves which move forward in time, and a negative solution, advanced waves which move backward in time. In 1941 the mathematician Luigi Fantappiè demonstrated that advanced waves concentrate energy, produce differentiation and structures, and show qualities which are identical to those which can be observed in living systems. In this way, Fantappiè arrived at the conclusion that living systems are a manifestation of causes originated in the future (retrocausality).
