The direction of time: from the global arrow to the local arrow
Mario Castagnino, Luis Lara, Olimpia Lombardi
Abstract
In this paper we discuss the traditional approaches to the problem of the arrow of time. On the basis of this discussion we adopt a global and non-entropic approach, according to which the arrow of time has a global origin and is an intrinsic, geometrical feature of space-time. Finally, we show how the global arrow is translated into local terms as a local time-asymmetric flux of energy
