The article currently says "A simple example of a duality is the equivalence of particle physics upon replacing matter with antimatter; describing our universe in terms of anti-particles would yield identical predictions for any possible experiment.". Isn't this a poor analogy, since C symmetry and CP symmetry are not accurate, and antimatter does not behave like a mirror image of matter when the arrow of time is the same? Would it be worth including if CPT symmetry is explicitly mentioned? Elroch (talk) 11:57, 20 September 2015 (UTC)
