Being as c is constant with EM radiation in a vacuum, light actually provides a stable yardstick whereby all further relative measurements e.g. time, distance, mass, energy, etc, reduce to mere absolute distance/absolute time measure. Imagine the absolute distance a photon will travel within an absolute interval of time. Such temporal and distance intervals are absolute, as seen by being able to adjust our relative ruler or clock by Relativity whereby arriving at an absolute position. The wavelength and frequency aspects of an EM wave provide absolute intervals or rather an absolute ruler, whereby it is our relative measure of these intervals due to our velocity which is the aspect which hides the absolute objective universe from our comprehension due to further relativistic interpretation from the subjective aspects of the dilating clock and contracting ruler.

Imagine that the static scale in the above image is the absolute ruler provided by the wavelength/frequency aspects of an EM wave. Now imagine that to measure this distance (as with the old wheel type measuring devices), we must have two values of measure, to properly define distance i.e. distance/time. Now we know that distance and time have a reciprocal relationship as velocity increases to near c, thus we can possibly imagine them as two gears measuring the same aspect, i.e.absolute distance. The rate at which the two gear assemblies move down the scale is irrelevant, as both represent extremely different velocities of a relativistic factor of 8 which is somewhere around .99216c within the higher velocity reference frame. The point being, that due to the fact that we must have two gears to measure with, our velocity determines the ratio of these gears, whereby it isn't the rate of animated motion which represents the velocity being investigated within the two images, it is the ratio of the gears to each other. From this perspective, relative time and distance are measures of the same absolute aspect of absolute distance, whereby the velocity of the frame of reference establishes the gear ratio whereby the time dilation and length contraction we find is merely two values of the absolute distance we find due to the gear ratio by which we are measuring with. I still need to put more thought into this approach, but I feel as though Relativity and Quantum Mechanics can be reduced to Classical Mechanics due to the proper application of absolute distance and time aspects. It is our relative ruler and clock which allows for every misunderstanding from the seeming lack of simultaneity all the way to the seeming necessity of uncertainty, however, to the universe simultaneity does exist amongst interactions with a proper cause and effect relationship, with no uncertainty of the relationship of all systems relational to all other systems by way of temporal and spatial intervals.

Notice how that with every absolute interval measured by way of the two animations within the above image, an absolute quantity was measured whereby that which wasn't recorded as distance was recorded as time in the lower velocity animation on the left, and that which wasn't recorded as time was recorded as distance in the higher velocity animation of the right. Thus, all absolute aspects were relatively conserved. This all gets into the relativistic blue shift mechanics due to increased velocity, which we discussed the other day, which I'll further elaborate on later.
