The cut of time
arXiv:1909.08966
Abstract
After a short review on the use of time in various branches of physics, I suggest to change the interpretation of time, from a duration to a cut. A reassessment of terminology is also required to avoid meaning traps. I also address the problem of estimating the energy needed by a physical object to shift in time without any other interaction or motion, that is, only to exist.
