The Probability of Antiparticles Breaking Special Relativity

The probability for a particle to break special relativity and appear in Andromeda is canceled out by the probability for an antiparticle to do the opposite. So when the probabilities cancel out, those things just don't happen in the universe. And so if you bring quantum mechanics and special relativity together and you include antiparticles, then it all clicks together perfectly - there are no violations of causality.
