We consider soliton solutions to gauge theories in non-commutative geometry and demonstrate a remarkable fact that these objects can travel faster than the speed of light for arbitrarily long distances, dispite the fact that theory is apprently Lorentz invariant at large distances. An explanation of this phenomenon will be provided in terms of string theory.
