The existence of superluminal particles is consistent with the   kinematics of Einstein's special theory of relativity
  Within an axiomatic framework of kinematics, we prove that the existence of faster than light particles is logically independent of Einstein's special theory of relativity. Consequently, it is consistent with the kinematics of special relativity that there might be faster than light particles.
