Special Relativity states that nothing can move AT the speed of light. it doesn't seem to have problems with things moving faster THAN the speed of light- as long as you can get there. The problem is that it takes an infinite amount of acceleration over a finite amount of time, or a finite amount of acceleration over an infinite amount of time, to reach the speed of light. add the fact that once you are travelling the speed of light you have other infinite properties (your mass and energy would cause you some major problems), it seems that travel AT the speed of light is problematic.
Photons and Gravitons, along with all the other "massless particles," don't have any problem going the speed of light because they are "massless."
Tachyons are theoretical particles that move faster than c, and they have some interesting properties.
