THE NATURAL PARADOX OF TIME

The displacement is defined as the change of place or position relative to a spatial reference point. This displacement may be linear (1D) and curved (2D). The becoming or universal movement is the continuous change of some characteristic or property that bodies and phenomena experience in relation to a beginning or origin. The sound of a song is a displacement (spatial movement) that has a beginning, continuity or several nows and an end (becoming). Similarly a moving body in space presents a becoming. 

All the phenomena of nature, society and mind have a becoming. Time is the extension and measurement of becoming. Time = becoming (a-b). "a" is the initial reference moment (IRM) of the interval a-b.

The grandfather paradox (time travel) and the twin paradox are science fiction. The natural paradox of time suggests that continuity = several nows. It's a paradox because there is only one real now connected to other nows that were real.
