The classical physics with its irremovable bases and primary concepts of space, time, mass and force is known. We also know that after A. Einstein and H. Minkowski the time has lost its apriority and the basic concepts have become a new interpretation.
Time is a usual coordinate of the four-dimensional world.
There is a possibility of further reseach. In this case a large area of natural sciences becomes open, the area, where the main theoretical assumption is that of non- homogenity of time. Such theoretical assumption is possible already within physics as one of the human cognition branches. However, the urgent requirement to do it comes from the area of the psychological realities of subjective times flow both of dofferent people and a concrete person times. In the special relativity theory non-homogenity of time is already accepted.
