Addendum
Because I've had discussions where some people have misunderstood what I said was indisputable in a direct observation, I've added this addendum. I’m not talking about one questioning an interpretation, or if there is more to it than can be directly observed. I hope the addendum adds some clarity and insight to the observable physical functions I discussed. For the Earths rotation, the pendulum swing of a grandfather clock, the oscillation of a quartz crystal, etc., they are all observable physical processes that happen in time used to define a unit of time. That observable process is not disputable, that they change position at a relatively consistent speed per distance. We equate that physical process to a unit of time. What is absolute for distance to have any physical relevance is also indisputable however, I’ve known this aspect to be more difficult to recognize. While I stated it requires in some form a change of position of energy, perhaps that might be cl...
