well, according to Einstein's thory nothing can every travel at a speed equal or exceeding the speed of the light. the reason is simple. assume that you are standing on a fast moving train. if you throw a ball foward, the ball will move at the speed of your arm strength + the speed of the train, meaning that the speed of the ball can be increased. however, if you flash a flash light on the train, the light does not go faster, meaning that it is already at the fastest speed possible. this means that nothing can go faster or equal to the speed of light.
