I read about an interesting about a test in the UK a couple of years ago where researchers were about to slow down light using various gases, the side effect of the research proofed that the exact speed of light is not a constant and can change given the enviroment it is in, gravity can also bend light.

Thus since the speed of light it not a constant, traveling faster than it is possible in theory. But the more interesting research is in using high-powered laser looped on themselves to created a wormhole in space/time for time travel and space teleporting.

It may well turn out that trying to travel that way will be akin to going from New York to Beijing by tunnelling through the planet.

We've known for quite some time that light slows down while traveling through various media. That's the reason for refraction in water or glass, for example.

I haven't heard of anything that increases light's speed.

No, flat spacetime speed of light is the issue here.

Not about subjecting it through gasses.

A fork travels through a chocolate cake faster than the speed of light. Think about it.

No every claimed the speed of light is constant, regardless of the media it is traveling in. What is claimed is that the speed of light *in a vacuum* is the same for all observers, regardless of relative motion. Some aspects of super-string/twistor theory seem to indicate that the speed of light, in a vacuum, *should* be changing over time.

Diamonds reduce light to about 60% of lights speed in a vaccuum. That's why its refraction raating is so high.
