In this paper, we introduce solitary solutions of the nonlinear multi-field sine-Gordon system. Despite the use of several independent entangled fields to introduce this system, but the collective behavior of these fields can lead to kink (antikink) solutions with the same macroscopic characteristics. In other words, a kink can be constructed in infinitely different states in terms of internal structure. The important point about this internal structure is that the output of the collisions is effectively dependent on it and we are actually witnessing an uncertainty in the output of the collisions. Radiative solutions are another type of solution of the multi-field sine-Gordon system that naturally appears in all kink-antikink collisions. Conversely, the collision of two topological radiative solutions can result in the creation of a kink-antikink pair.
