Question

Is there an antimatter equivalent to light?

Answer

Dave - In some sense it does. There is an antimatter equivalent to a photon. It's not an antiphoton. If you have two photons you know are in exactly the opposite phase they can cancel each other out. As far as we know the photon is its own antiparticle.
