Relativistic light shift always results in a redshift
I have been thinking about relativistic gamma in relation to this.
I don’t want to appear to be discouraging. We do know for a fact that the quantification of time uses some form of clock, and we know that the rate that a clock measures the passing of time is affected by the relative acceleration of that clock vs some presumed rest clock.Unfortunately there is no absolute space in which to place our rest clock, and so there is no absolute measure of time. Therefore, time is relative to conditions of local energy density set up by differences in gravitational potential, relative motion, and/or applied forces between two clocks in relative motion. The conditions of each clock in relative motion are therefore different.I don’t see how you can get to anything fundamental in regard to a time increment from those circumstances, so I personally settle for the concept that time simply passes, but the measure of the rate that time passes is relative to the differing conditions in which our clocks are located.On the bright side, maybe there is some fundamental increment of energy based on some foundational minimum background energy level. If such an energy level could not be reduced below this as yet unknown natural limit, and if we could place our rest clock there, maybe all other frames could be compared to that clock.
One conclusion I am contemplating is that time is not fundamental in regard to the rate that it is measured to be passing on a given clock, because various changes will affect the rate that the clock will measure the passing of time. For example, if that clock is moved from location to location (accelerated/decelerated relative to the home conditions),
No, the real problem is the other way round. The moving clock ticks at a constant rate (the fundamental time if you like), it is the other clocks (whether considering themselves at rest or moving) that measure that clock’s time as different to their own. Each clock records its own proper time as it moves along its worldline. So, the “various changes” do not “affect the rate that clock is measuring the passing of time” only the rate that other clocks measure it.
