"If the theory of syntropy is correct, three levels of time must exist. The sequential time to which we are accustomed to, in which energy is divergent and entropy prevails, would be typical of expanding systems, such as our universe.

At this level time is unitary and past, present and future coexist.” read more in the article "Luigi Fantappié and the physics of life"
