The Problem of Relative and Absolute Motion within Special Relativity.

According to Special Relativity (SR) theory, all motion is relative to the local observer.
Therefore all motion is relative motion.
As the local observer is identical to itself, the local motion is an absolute motion relative to itself.
As there are many possible observers within the universe, there are many local motions that are absolute motions of each possible observer.
Therefore all motion is absolute motion, relative to the local observer.

As every motion is locally absolute, every motion is locally moving relative to the universe.
The local absolute motion is then known as an absolute motion relative to the universe.
Therefore all motion is absolute motion, relative to the universe.

As all motion is absolute, relative to both the local observer and the universe, all motion is absolute.
But SR theory says all motion is only relative to the observer.
Therefore, SR theory has a false postulate concerning the motion of things that are only ever relative to local observers, without reference to any absolute motion.
