How Many Models of Time do We Need in Physics

Amrit Sorli


Elementary perception (sight) and experimental data confirm we measure with clocks sequential numerical order of events which means that flow of time has only the mathematical existence. The idea of some physical flow of time has no support in elementary perception and experimental data and should be abandoned. On the other hand in today physics, we have several other models of time: coordinate time, proper time, internal time, external time, thermal time, cosmic time. None of these times we are able to observe with our senses. In this article it is shown these models of time have no real physical existence, they are pure theoretical mistakes.


Flow of time, Cosmic time, Internal time, External time, Thermal time, Coordinate time, Psychological time
