ABSTRACT
Time is probably one of the most essential and paradoxical concepts that human beings face. Time is always present in our everyday life from the perception of events to the development of human thinking behaviours. However, time is still a difficult concept to describe and formalise as it has no obvious physical characteristics and properties. We can only establish a temporal statement from the observation or prevision of changes. The relationship between time and space is a consequence of the observation of changes as the perception of spatial alterations denotes the existence of time.
