If you travel faster than light, then bad things start to happen like I said. You catch up with your own light emmisions, which would build up under newtonian physics, and you would vaporize the front of your vessel. If you tried shooting any energy weapons, what shot the energy beam would get hit by the energy beam. Optical devices would cease to function as they cannot travel forward to the axis of movement, due to going faster than light. It would be impossible to see behind you, because of you moving faster than light. Light would have more energy relative to you, so any energy weapons fired at you would do exponential amounts of damage. If you're moving 10x the speed of light, then energy weapons fired directly at you from in front would do 11x times the damage. The good side is that noone can see you coming
