What are the different mechanisms for producing light or radiation. Annihilation comes to my mind. What are some other ways?
Also, what state of matter is light? Given that a high energy photon* flows for an infinite amount of time through 'empty' space will it stay as it is forever or would there be a possibility of it changing into something else?
