The Problem of the loss of Absolute Length within Special Relativity.

SR removes the ether and replaces the notion of absolute length with a measured length by the observer.
But length measured by the observer, varies with the observers motion.
Hence two observers viewing two identical objects, will see each object as smaller than each object's absolute length.
Yet both observer's know that each object is identical in length.
Therefore the observed length is always shorter than the real length.
Therefore according to SR, all observations of lengths are fictional, contrary to the principle of identity, L=L,
Hence according to SR, observation is always at variance from a fundamental principle of being.
Therefore SR theory infers all observations of lengths external to the observer are all fictional lengths.
