The production or export of entropy from open systems leads to an entropy flow through three-dimensional space, whereby the fourth dimension of spacetime, time, is formed. The time we measure is proportional to the entropy production, to the flow of entropy. Time is a kind of matrix in which entropy flows.
The more entropy flows (= the more change occurring), the quicker time is passing by, and vice versa. In consequence, there is no universal time, not in the universe, not on earth, not in ourselves. We humans just determine ‘time’ as what we measure when looking at the sun (daily sunrise and sunset) and the yearly seasons – or in modern terms – ‘ground-state hyperfine transition frequency of the cesium-133 atom, to be 9,192,631,770 when expressed in the unit Hz, which is equal to s−1’, as the second is defined in SI base units. Each clock produces entropy, also atomic clocks, and when comparing their time measurement on earth with what we observe in a satellite with slower or quicker time flow, this is without doubt linked with more or less intensive entropy flow.
