This paper proves the existence of two inertial reference frames A and B in which the relative uniform velocity of A with respect to B is real, while the reciprocal relative uniform velocity of B with respect to A is only apparent, as apparent and unreal as the daily rotation of the Sun around the Earth. An asymmetry due to the fact that only A underwent a brief acceleration that changed its previous uniform relative velocity with respect to B, so that the corresponding reciprocal change in the uniform relative velocity of B with respect to A, as observed from A, has no physical cause. It is therefore an apparent change in velocity, from which only an apparent uniform velocity can result. This symmetry breaking violates the Principle of Relativity.
