Resumen:
In several previous papers we have argued for a global and non-entropic approach to the problem of the arrow of time, according to which the "arrow" is only a metaphorical way of expressing the geometrical time-asymmetry of the universe. We have also shown that, under definite conditions, this global time-asymmetry can be transferred to local contexts as an energy flow that points to the same temporal direction all over the space-time. The aim of this workis to complete the global and non-entropic program by showing that our approach is able to account for irreversible local phenomena, which have been traditionally considered as the physical origin of the arrow of time.
