Irreversibility

A quality which makes reversion to the original state impossible, determining the passage into a qualitatively new state. Irreversibility is inherent, to a greater or lesser degree, in all processes in the world. This is determined: (1) by the infinity of matter, the inexhaustible complexity of its structure, and its countless potentialities for change, which cannot be fully realized in any finite period of time; (2) the fact that all the existing material systems are not closed in principle, the diversity of their external ties which are constantly changing and transfer the system into a new state.

That is why every cyclical process includes an element of irreversible change, which is expressed in the general irreversible run of time from the past to the future. Irreversibility of change cannot be reduced to some kind of change in one direction. Development along an ascending line or, the reverse, the degradation of a system with its subsequent death, are specific cases of Irreversibility. Change in one direction can occur only in finite systems. In the infinite Universe Irreversibility presupposes changes in the most diverse directions and never-ending emergence of fundamentally new possibilities of development.
