3drob, superconductivity is an interesting and useful analogy for this optical technology--thanks for that.

I've always accepted the constant of the speed of light without considering the difference of the various mediums through which it passes.  Obviously, air is thicker than outer space -- just never thought about it!   I can imagine as science refines the need for this distinction, it will grow in relevance in many applications.

Psssst – good luck on collecting any royalties on infringements of that patent!

TJ, that speed limit is still firm, at least in air and vacuums. This "broken" speed limit is through a material. But I agree, wouldn't it be fun if the whole concept of FTL travel of some sort became possible?

Ann, yes I meant to ask if they had actually demonstrated a decrease (not increase) in data transit times.  I didn't mean to imply I was expecting faster than light (in a vacuum) transmissions.  This is actually one of those areas were semantics are quite important.  Claiming "faster than the speed of light" can mean two things:  faster than light in a vacuum (perfectly allowable by the laws of physics, but hard to prove and impossible to do) and faster than light in a medium (less impressive, but still very useful).

Piping light through a material faster than light travels thru the material is akin to superconductivity (which makes current flow with the minimum possible resistance).  This discovery promises reduce the transit times of data in a medium to the minimum possible (equivalent to light in a vacuum).  Not only an improvement on current technology, but the best than can be expected.

3drob, I think you mean "to actually decrease [not increase] data transmit time", correct? Assuming you meant "decrease", the answer is no, the discovery doesn't permit this--see laser_scientist's comment above yours.

Non-metaphysical filter

What I seem to think is happening here is that the light is passing through this material as fast as the material can allow. The structure is such that the flow of photons is unrestricted by the material. As this described as a kind  of filter, it is exactly that. A very useful discovery, but hardly metaphysical ;)

Rob, thanks for the laugh (wow, two in one day on one post!). I don't know about matter and thought, but Einstein said that matter and energy were closely related (although that relationship as expressed in his famous equation did involve a very, very large number). But kidding aside, I know what you mean.

Battar, thanks for the laugh: that it's possible to patent something--FTL transmission--before it's actually been invented in the sense of being actually built.
