On p. 99 of his book, Relativity, Einstein said “Mechanical clocks serve for the definition of time.”

Due to inertial mass, the rate of functioning--the measurement of events in sequences by time-intervals--of mechanical clocks is affected by changes of velocity/gravity.

Increase velocity/gravity and the rate of functioning of a mechanical clock slows down; decrease the velocity/gravity and the rate of functioning increases. Accelerate a spaceclock via a ride on a spaceship and its inertial mass increases and its time-interval increases and it reads fewer time-interval measurements and time appears to slow down when compared to a similar earth clock which is not accelerated.

Thus, mechanical stuffs undergo changes of rates of functioning due to changes of inertial mass due to changes of velocity/gravity.

Biological stuffs also undergo changes of rates of functioning due to changes of inertial mass due to changes of velocity/gravity. If the subjective experience of changes of rates of functioning is none, then the individual will not necessarily realize that his rate of functioning is changing, and he will continue to observe the speed of light as 186K mps in his reference frame.</strong>

Up to here, you're doing fine.

<strong>The rate of functioning of mechanical and biological stuffs is similar to the frames per unit of time of a camera wherein slower rates of frames per unit of time produces time lapse photography and an apparent/perceived increase in velocity when a film is played at whatever is considered to be ‘normal’ rates of frames per unit of time and faster rates of frames per unit of time produces slow motion photography and an apparent/perceived decrease in velocity when a slow motion film is played at the ‘normal’ rate of frames per unit of time. Most of us have seen this phenomenon via movies/tv/videos/etc.

Changes of velocity/gravity thus produce changes of inertial mass which produce changes of rates of functioning which produce changes of time-intervals used to measure time as the observation of events in sequences of events a.k.a. history.

This is the setup info for defining time-intervals subject to changes of velocity/gravity as variable time-intervals.

Time using variable time-intervals is clearly what Einstein specified time to be in developing his theory of relativity [originally titled the theory of invariants, as I recall].

Time and space thus appear to be intertwined/interrelated when variable time-intervals are used for the measurement of time.

Question: What happens if invariable time-intervals are used in (A) clocks which are velocity/gravity sensing [they sense changes of velocity/gravity] and self-adjusting to compensate for detected velocity/gravity changes or (B) clocks which are synchronized via radio signals to an earth clock?</strong>

Here is where you jump the tracks. Two serious misconceptions - first, that there is something somehow more correct about the first clock's original reference frame, and less obviously, that it is even possible to synchronize to clocks moving in different reference frames. It isn't possible to synchronize them, because simultaneity also vanishes - you don't get the same time for different positions in that reference frame. There is no absolute time in relativity theory, and the theory has been experimentally verified to the point where this should no longer be a question.

Bob K: Skydancer: Velocity/gravity sensing self-adjusting clocks would show the same face readings/measurements of invariable time-intervals and therefore would be measuring Absolute Time.

Clocks, as explained to me by a Professor of Physics who is a friend, can be synchronized and if so then would show the same face readings/measurements of invariable time-intervals.

If you are having trouble imagining how clocks could have the same face readings/measurements of invariable time-intervals try a gedankenexperiment (German: thought-experiment--intuition, as used by Einstein and others) and imagine clocks that are by definition impervious to the effects of changes of velocity/gravity (don’t ask how--just accept the premise); those clocks would show the same face readings regardless of their velocity, presence in a gravitational field, position in a reference frame, etc., because all reference frames timewise become the same as the K zero reference frame, which is the Absolute Rest reference frame, and thus these clocks would measure Absolute Time. And with Absolute time you get Absolute Space, hence spacetime is meaningful only when you are using clocks with variable time-intervals and such clocks are subject to the effects of changes of velocity/gravity.

I do not believe that you fully understand the concept of the invariable time-interval and how it measures Absolute Time, defined as the time found in the K zero or Absolute Rest reference frame. Only in the K zero reference frame does light travel at 186K mps And only in the K zero reference frame when there is zero gravity will mechanical stuffs and biological stuffs function at their highest rate of speed, because at Absolute Rest the velocity is zero, hence no increase in inertial mass, and if there is no gravity, howsoever that might happen, then there is no increase in inertial mass, therefore nothing to slow the rates of functioning of the mechanical or biological stuffs.

Howsoever constructed or defined, the timepieces using/producing invariable time-intervals read the same face readings/measurements of invariable time-intervals everywhere and anywhere in the universe and therefore provide a temporal reality by which synchronicity can be determined and measured: those events occurring at the same invariable time-interval clock face readings/measurements are thereby synchronized.

One more time: Clocks using variable time-intervals are affected by changes of velocity/gravity and their face readings/time measurements vary according to changes of velocity/gravity; clocks using invariable time-intervals do not vary despite changes of velocity/gravity and their face readings/time measurements are identical, and always moving forwards into time, and produce the temporal asymmetry which creates history.

Fascinating stuff, guys. I even understood some of it.
