Abstract
Times Arrow existence is well illustrated by geology and other sciences such as geography, biology and chemistry. But investigator of geological reality has same hardness and contradiction which unknown for specialists in other sciences. Times Arrow appearance is condition by interaction Earth’s structural heterogeneity substance (dimensions from nx10^-6 m to nx10^7 m) with processes its transformations. Each degree of Heterogeneity substance of Earth is learning with methods of specialty geological sciences. Heterogeneity substance of Earth degree stays more and more and there fore the system “forgets” its past that causes every geological object is uncial. No any geological process could go backwards to his beginning. The time geological process is incommensurable with the time of humanity civilization. Every geological process indicated by great number causes, and there fore we never could know everything about these processes and these causes. Geological science is historical knowledge by the method because of the uncial character geological objects. The influence uncial objects to itch other could not prognosticate and there is no one ontology, but poly-ontology these objects. In this case the investigator can observe only results of geological processes, not there proceed. Prognosis in geological sciences is not prognosis non-existent events. Usually prognosis in geological sciences is prediction about latent properties already existing geological object, but unexplored or inaccessible to specialists.
