Ambivalence of Time

Abstract

The physical nature of Time is researched. Time is considered as a set of phenomena that can be divided into two fundamentally different, but interrelated groups (time sides). The first group is connected with the metric properties and topological concepts of space-time manifold, the integral part of which is Time. This side of time integrates it with spatial dimension. The second group includes physical properties connected with spontaneous time coordinate increment of massive particles (the flow of time). It provides the variation of systems and the development of physical processes in the environment. The difference between time and space can be seen here. Thus, time ambivalence (duality) is shown. Time ambivalence is one of the key temporology principles. It is impossible to build an adequate time theory without considering it.
