@Carl J Mesaros,
Absolute is what it is: REALITY
Relative is what we mostly perceive of reality.
In what Science is about, when we talk in reference to our perception of the universe -physically speaking-, Newton was correct while Einstein was practically a poor lunatic.
The Relativity theory stinks. Time doesn't exist physically, so the idea that time is flexible and subjected to the speed of objects and density and gravity of bodies is completely laughable.
The error of Einstein was to take for granted the conventional idea that time flows. This is nothing but an old and obsolete conventional idea. Until today, nothing, absolutely nothing can perceive such time flowing. Clocks are not other thing but devices calibrated to a fixed functional work: "tic tic tic..."
An old clowckwise toy works exactly as the clock does, and this toy cannot measure any passage of time as well. The idea that clocks measurte "the passage of time" is not only absurd but a lunacy, as the Relativity theory is.
So, having that time is nothing but a measure, like weight, volume, etc. we know now that Newton was closer to Reality -because he assumed it as absolute- while Einstein becomes the greater clown in science history.
Time, as a measure, can be accepted as "absolute", because is a fixed period of motion. We divided the regular rotation of earth facing the Sun in 24 parts (hours) and these parts in minutes and seconds. These measurements are "absolute".
The atomic clock works by counting the vibration frequency of the atom of Cesium, this means, 9,192,631,770 vibrations and "TIC"... 9,192,631,770 vibrations another "TIC" etc... See? This is all what the atomic clock is, another "tic tic tic" calibrated device. When the atom of Cesium is exposed to acceleration or different gravity, the regular period of its vibration frequency is affected, so there is not such a thing as "time dilatation" but it is a simple and expected clock malfunction.
The relation between the absolute and the relative is mostly how accurate we do perceive reality, and Newton was very good, while Einstein... ha ha ha... that poor idiot...
