Time in Physics and Philochrony
This is the first time that I relate Physics and Philochrony regarding the subject of time. For physics, time is what clocks measure (Albert Einstein). According to Wikipedia, time is the physical magnitude with which the duration or separation of things is measured. But these definitions are incomplete because, what do clocks measure? Time. With this we would fall into a vicious circle. In the definition of Wikipedia, what is duration ? For some physicists, including Julian Barbur, time is an illusion, it does not exist. Isaac Newton resorted to a metaphor to explain time. Newton said that time is like an invisible river in which everything happens. Physics is about material and tangible objects, and time is intangible. Time is imperceptible and unobservable to physical equations.
For Philochrony time is derived from the word interval. So time is the distance or separation between two sequential moments one of which occurs before and the other after. For this reason time is 1D sequential space.
It is already known that time is magnitive, that is, objective, subperceptible and measurable. It is objective because the intervals are real. It is subperceptible because we do not perceive the intervals at once, but we see the beginning before and the end after. It is obvious that it is measurable by means of periodic phenomena.
In conclusion:
Physics provides the tools to measure time, clocks. Philochrony proves the existence of time and provides a theory about its nature.
