In Richard Feynman's book "Five Easy Pieces", Feynman describes a particular picture of particles emmited after a collision in which he points out a particular particle path that he says is a meson travelling backwards in time.
In my humble opinion, if Feynman is right, then the second law of thermodynamics is not always true.
