“There is no single time: there is a different duration for every trajectory; and time passes at different rhythms according to place and speed. It is not directional; the difference between past and future does not exist in the elementary euqations of the world; its oritentation is merely a contigent aspect that appears when we look at things and neglect the details. In this blurred view, the past of the universe was in a curioysly “particular” state. The notion of the “present” does not work; in the vast universe there is nothing that we can resonably call “present”. The substratum that determines the duration of time is not an independent entity, different from the others that make up the world; it is an aspect of a dynamic field. It jumps, fluactuates, materializies only by interacting, and is not to be found beneath a minimum scale.”
