The Problem of Third Universal Observer Implied within Special Relativity.

Special Relativity assumes light is at c, and observers see motion in accord with the transforms that require a knowledge of the observer's velocity relative to that which is observed.
The value of light at c, and the relative velocities of the observer to that of the thing being observed at v are both absolute values known to the third observer who knows all.
The third observer is like the divine mind who knows all absolute values and places those velocity and distance values into the equations to derive the transformed velocity and distance values of the Special Relativity equations.
As such values are never known in the real, for no observer knows the absolute value of light at c, or the relative observer velocity at v, the transforms and the associated SR equations are only ever paper fictions.
As the SR theory assumes a universal third observer within the theory that does not exist in the real, SR theory is only ever a paper fiction.
