How far does it travel? and How Fast? Cause, technically, flying at his fastest speed, would he be able to utilize them propely (i.e., shoot them out his eyes) cause he could probaly outfly them and then, they would only be like, really hot eyes or like two big lightsabers coming out of his eyes, but not really shooting anymore, right? (i'm thinking straight ahead flying and eyesight here) Can he burn them through the earth, given enough time?
Am I making any sense here?
