What are the factors, excluding time, on which the destination location by time depends? What is the reason why we perceive time as never passed when the position remained the same, but as quickly past when it is very different? Is increased mobility accelerating time? Is the 'speed', the distinction between the old and the contemporary? On the other hand, in either case, the 'conteporary', looking back from the 'end' position, which is more or less different from the beginning, says that time passes very quickly. If time passing 'like a wind' is a perception valid both for those who are constantly in the same place and who move a lot, shouldn't there be a concept beyond time? Speed involves a magnitude other than time, the 'path'. The path travelled is the change in location. For a person who does not move, the fact that the days do not pass (0 / ∞) or do pass very quickly (0/0) indicates the mathematical uncertainty or meaninglessnes
