Absolute can be used to emphasize the word truth, but consider the opposite, a true absolute.
Which is?
What does the term "absolute" mean?
Logically that it is all-encompassing.
The term "partial truth" is coherent, as much of the information we deal with is often only partially true.
Yet "partial absolute" would be a contradiction of terms.
The only common use of the term is a temperature of "absolute zero." Meaning no motion at all. A total equilibrium.
Now consider the premise of "spacetime" is based on the fact that in a moving frame, measurements of both time and distance are dilated equally, given the combination of the motion of the frame and any action in the frame can't exceed C. Such that in a frame moving at the speed of light, time stops and distance shrinks to zero, as nothing can be measured.
Yet go the other direction; Evidently the frame with the fastest clock and longest ruler would be the one closest to the equilibrium of the vacuum. The unmoving void of absolute zero.
Consider the implications of that.
Time would cease as well, as there would be nothing to measure.
Yet would space? What is space, other than the void? The ruler can't just shrink to a point, as that would be a reference. Something rather than nothing.
Consider that as mobile organisms, this sentient interface our body has with its situation functions as a sequence of perceptions, in order to navigate, so our sense of time is the present going past to future.
It is the basis of culture and civilization, as narrative and history. Human knowledge being a process of building on what came before is an effect of this flow. Science codifies it as measures of duration.
Yet the evident reality is that activity and the resulting change turns future to past. Tomorrow becomes yesterday, because the earth turns.
Potential, actual residual. Duration is the present, as the events come and go.
There is no dimension of time, because the past is consumed by the present, to inform and drive it. Causality and conservation of energy. Cause becomes effect.
It's like a tapestry being woven of strands being pulled from what was woven.
Different clocks can run at different rates simply because they are separate actions. Think metabolism. That culture is about synchronizing society as a larger entity using the same languages, rules, measures, it might seem there should be only one Newtonian flow, but it's rabbit time and turtle time.
Energy is conserved, because it manifests this presence, creating time, temperature, pressure, color and sound, as frequencies and amplitudes, rates and degrees.
So energy, as presence, goes past to future, because the patterns generated come and go, future to past. Energy drives the wave, the fluctuations rise and fall. No tiny strings necessary.
The music is more real than the matter.
As consciousness also goes past to future, while the perceptions, emotions and thoughts giving it form and structure go future to past, it suggests consciousness functions as an energy.
As the digestive system processes the energy, feeding the flame, while the nervous system sorts the patterns, signals from the noise, with the circulation system in the middle, there is a definite intellectual focus on the forms, the information, than the processes generating them.
Ideal gas laws correlate volume with temperature and pressure, but we don't confuse them with space, even though they are as foundational to our emotions and bodily functions, as sequence is to thought.
So if time is simply a measure and effect, like temperature, than what is space?
It is described as three dimensions, but they are a mapping device, like longitude, latitude and altitude.
It would seem the two qualities space does possess are infinity and equilibrium. The absolute and the infinite.
Everything in-between would seem to be relational, between the energies manifesting and the forms defining.
Galaxies are energy radiating out, toward infinity, as structure coalesces in, seemingly toward equilibrium.
