Light always travels at the speed of light. Now if you change the speed of light, like with a piece of glass or water or a plasma then the light will go that speed, but it is still the speed of light it is just slower than c.
If you look at the relativistic equations they contain the letter c, so everything is setup so that you cant get to it or make stuff go faster than it.
