Subjective Time Versus Physical Time

[Andemicael, previously] 1. Relativity, as we know, predicts that variations in velocity alter the appearance/characteristics of physical reality. But these effects/distortions are of no consequence to temporal passage: this phenomenon maintains its steady, relentless flow, regardless of the physical circumstances.

What is duration?

Duration may be defined as "a period of *elapsed* or *elapsing* time."

If we were to characterize the disparity between points A and B as "a duration of one year," we would be claiming the following:

*** "The time that elapses when an individual relocates from A to B is *precisely* one year: i.e., this relocation can never be achieved in a time period that is less than one year or greater than one year."

Consider two points on the fourth physical dimension: say the point "Jan. 1, 2010 AD" (point-X) and the point "Jan. 1, 2011 AD" (point-Y). It is, of course, possible for an individual to relocate from X to Y in exactly one year of ELAPSED time. But this period can be reduced.

An observer may accelerate to a velocity much higher than that of the earth, and eventually decelerate. This physical scenario, as we know, permits relocation from 2010 to 2011 in an elapsed period that is less than one year.

By definition: the amount of time that elapses from the beginning to the end of a duration does not vary.

Notice, however:

The endpoints X and Y are *not* uniquely associated with a particular intervening duration...

(...relativistic "time dilation" effects do not in any way affect the steady, normal flow of [subjective] time).

[Andemicael] An *elapsed* duration (say, one second) is a *fixed* quantity. The endpoints of a one-second duration (call them points A and B) are precisely one second apart regardless of the frame of reference. (Being an absolute quantity, this period does not get shorter or longer depending on the reference frame.) As we know, however, the spacetime events (S1 and S2) that are associated with these *fixed* endpoints (A and B) *do* vary, depending on the reference frame.
