**Abstract:**

There is an objective impossibility (prohibition) for simultaneous accurate measurement of length and time in nature. When the length is exact, the time is approximate and back when the time is exact, the length becomes approximate. The Ratio of indefiniteness confirms the Second postulate only in the part that the speed of light is a constant with a limit value с . Respectively, it refutes the Second postulate in the assertion that, as path and time, the directions "going" and "return" of the light signal always (in all systems) are fully equivalent. The Second postulate, as defined in the Special Theory will is entirely valid only in an absolutely stationary system. In this sense the ratio exact length/exact time, what offers us the Theory thanks to the in question postulate, can be achieved solely in the ideal (real inaccessible) conditions of this system. In other words, the Theory denies its existence, but in practice use it for their conclusions. The Ratio of indefiniteness speaks in support of the conclusions of the Spe- cial theory that the moving length and time are changing. Conversely, these findings of the Theory are argument for the veracity of the Ratio of indefiniteness. The same finds confirmation in the experimental results (Roemer – 1676, Sagnac – 1913 and others whose contemporary interpretation is wrong).
