And I think you are saying that if we were to read and learn GR, we would know the truth.
I agree with part of that though, time does not exist in the past or the future, it is always now as far as time is concerned, and time does not have any existence in and of itself.
And to be practical and not necessarily being contrary to GR, you are right about time and motion being inextricable entwined, but GR calls for the curvature of spacetime by the presence of matter and energy but does not acknowledge how that curves spacetime.
True, and hard as I try it is really difficult to visualize. The closest I can come to an analogy is that of the term 'displacement' of a submarine, the dimple in the water occupied by the submarine. Oddly, the displacement also governs the maximum speed a submarine can attain.
In the unlikely event that my interpretation of Marcus' comment is accurate, then the varying energy density in space, and particularly as you get closer to massive objects, causes a change in the rate that clocks measure time, not a change in the rate that time passes.
I need instruction on this for sure. From my standpoint, time is created during an event and there is no real passage of time, other than as accompanying the passage of events which take (create) time and create the chronological worldline of every change occurring in the entire spacetime universe, which is the record of the instants of time each event occurred at every spacetime coordinate; as best we can tell and sometimes by assigning different spacetime (time/distance) values, such as 'lightyear' or 'entanglement'.
IMO, somewhere in this vague world I believe that time is very much connected to quantum, which by its very nature has a built in time requirement to function. OTOH, the very potential that allows an event to happen, also imposes limits on how much time an event can take. A quantum event will take only enough time to create a quantum event. A muon's worldline as a muon is very, very short and then it disappears and no longer requires or creates time for its existence (as a muon).
And I see here an important consideration. When we say spacetime is warped we really mean the geometric shape of space is warped (folded) and this space distortion also creates as a RESULT folded time and along with variations in distances in the spacetime fabric accompanying variations in the passage of time. Stand close to a pyramid and time will slow down by it's massive gravitational spacetime distortions.
Sometimes a warp may compress space and things may seem to happen faster and sometimes space is stretched and things may seem to happen slower. Certain "equal" distances between coordinates are no longer equidistant from each other and anomalies begin to form in the worldliness of objects in such a spacetime curvature. As observable in "lensing" maybe?
Is it True?
That for any measurable change to be able to occur, a certain amount of time is required and time is always a result of an actual measurable change?
If yes, why do we assume time to exist where there is no change and I do not mean some sort of half life, but when all particles stop moving, when quantum itself stops, what would be the NEED for time?
This is why I maintain that time did not exist before the BB and was created during the 'inflationary epoch', the First mega quantum event where everything happened in the same space at the same time. A momentary chaos, which almost immediately began to order itself in accordance with this Universe's Potential. I just love Bohm's expression, the meta physical 'Implicate' of that which is to become 'Explicate' in reality, along with the amount of actual or relative time it may require.
