It’s almost self-evident that time is inextricably linked to physical processes. It was “linked” by us as an aid for living and nothing more.
It is a mental construct.
Imagine that the objects of our solar system never moved. Not that they stopped moving but, rather, that they never ever moved as well as being immobile now. There would be no ‘year’, ‘month’, ‘day’, ‘hour’, ‘minute’ or ‘second’. If we existed in this scenario and there were processes. then we could not make any references to time. I could tell someone to start a task and not to stop until I say to stop, but I could not pay that person “by the hour”, unless I reference a physical process. You might ask me how long I worked. I could say, “Long enough” or not and you can be sure that I’ll want to be paid for my labour.
Take any inert object. If nothing comes along and “interacts” with it ever, forever, then is it outside of time or timeless? It doesn’t matter (oops). And if you object to my usage of ‘ever’ and ‘forever’, as they insinuate the “existence” of time, then I tell you that there is no time without matter–which I avoid, that being somewhat obvious.
Time is inextricably linked to physical processes, as we conceive it; as we wish.
I know that this truth may hurt or offend some.
As I’ve expressed it, does it bring anything to your mind? The most exquisite human mental construct is?
Mathematics.
Both are essential to our lives, literally to how we exist.
If we sat around, ate slept and sat around some more, with no place to go and nothing to do we would not need “time”.
Only then would the word ‘inextricable’ not apply.
Remove us all and what is left? Matter and physical processes.
