What Is the Duration of a Clock?

A physicist has shown that to define a clockp perimeter, you basically need a minimu of three objects with correlated motions. All we need is three particles systems with correlated motion. So what are the things that are met that one can meaningfully talk about? Do you think it would even be meaningful to say that there has been an expansion or contraction if all that actually happened was everything scaled up or down? No, really. You won't know it, right? And i'm just saying that you need a bare minimum of three particles and their configurations as they change through time. Now let's plot a graph, which we're going to call the configuration,. Regular level when we're at
