Where did I said that without any physical object , there is no time?Invalid formula. The classical (Aristotelian) definition of ‘time’ is “the measure of the change” of physical objects. In other words, without any physical objects (or system), there is no such thing as time. (Which gives rise to the old joke: “What did God do before creation?” “Nothing – he didn’t have time!”)
That is exactly the problem that you have noticed. Time should exist in order to allow us to define changes.Anyway, your equation uses a variable (T) in reference to a state (S) in which the system did not exist. Essentially, you’re attempting to measure dS/d(NULL), which does not work.
No. Time is needed whenever you have a change. Please read my argument to another poster:Time comes into existence when S’ comes into existence. It cannot be used to measure anything before it, itself, exists!
We have a change in a system therefore we have two states related to change which are different. These two states cannot be at the same point since the state of system becomes ill-defined. Therefore these two states should be placed on different points. There is also a directionality in change because one state (first state) comes before another state (second state), this is another property of change. Up to here we realize that we need to a variable with at least two points which the first point comes before the second point. There should however be a duration between these two points otherwise the second state will never take place. This variable is therefore time.
