Abstract—What is ‘time’? Are all these just hours, minutes,seconds, days, months and years we count? Did the passing oftime even exist? Physics, based on Einsteinian relativity andmodern relational mechanics, shows that time is not some kindof background; it is a purely relative coordinate that is sodeeply inherent in the fabric of spacetime. In this paper, thisrelativistic view is expanded upon by marrying human subjectiveexperience in the sense of existential reflections on motion,biological decay, physical trauma, or illness, in quantum gravity,and non-equilibrium thermodynamics. We build a comprehensiveconceptual model that is coherent and consistent with the intuitivehuman experience, and is also verifiable with rigorous physicalmodels. Now, cosmic timekeeping broken down. By applyingrelativistic physics, we can show that the rotation period ofthe planets as well as the cycles of days, months and yearsmeasured by the calendar and clock do not correspond to whatnature measures as the "real time.Through the application of theprinciples of relativity we can show that the number of rotationsof the Earth-day, month, year, measured by a calendar- is not ameasure of true time as nature understands it. Instead, they arejust geometric indications of the planets’ bodies’ passage throughspace on circular orbits, not a subjective or fundamental currentof time. Secondly, structural degradation is studied. The situationof visible and imperceptible phenomena, biological ageing andnatural degradation, is comprehended on the basis of Clausius’sentropy production inequality dS ≥ 0, thus, in the context ofirreversible thermodynamic process. Moreover, we assess thepsychological time Cntour. Time-dilation or time-slowing in theacute phase of disease in severe cases is determined by measuringindividual outcomes in neuropsychological tests based on theneuro-phenomenological PACA model. It once again shows thatunder physical and emotional strain, man’s time is dilated inaccordance to the increase of information processing in the brainand follows a mathematical rule. Last, but not least, the Planckscale is discussed. The Wheeler-DeWitt equation, ˆHΨ = 0, showshow the world behaves in a manner that leaves no role for thetime parameter (t); this paper shows that this implies that thatparameter t is not a fundamental and measurable constituent ofthe world.
