It's real, but, as I explained 2 pages ago, what's being talked about are two different types of velocity: phase velocity and group velocity. Group velocity (the speed of the photons, themselves) must always be equal to exactly 299,792,458 m/s under any and all circumstances. Phase velocity (the speed of the wave) can be anything we want to make it - even, in this case, greater than light's group velocity.
Any time you hear of anyone speeding up or slowing down the speed of light, they're talking about the phase velocity, because the group velocity cannot be changed, ever. It's not nearly as impressive as these articles make it sound.edit on 15-12-2011 by CLPrime because: (no reason given)
