Liquid Light

Thanks to Quantum Mechanics, we know subatomic particles, like photons, can be a particle and/or a wave depending on how said entity interacts with it's environment. In the elegant Thomas Young interference experiment, the duality of same was shown to be true by one of the most beautiful experiments done in science.

Supposing the light of any given colour to consist of undulations of a given breadth, or of a given frequency, it follows that these undulations must be liable to those effects which we have already examined in the case of the waves of water and the pulses of sound. It has been shown that two equal series of waves, proceeding from centres near each other, may be seen to destroy each other's effects at certain points, and at other points to redouble them; and the beating of two sounds has been explained from a similar interference. We are now to apply the same principles to the alternate union and extinction of colours. - Thomas Young

Now it seems liquid light can do the same thing if one has the smarts and hardware to make it happen.

In recent years, however, research has indicated that light can also behave like a liquid — flowing around objects and reconstituting on the other side. Previously, this phenomenon has only been observed under certain extreme conditions, such as laboratory chambers chilled to near absolute zero.

New research published this week in the journal Nature Physics reveals that light can behave in an even stranger "superliquid" state, in which light particles flow around objects with no friction or viscosity at all. In this state, light exhibits the dramatic effect of "frictionless flow," bending around obstacles with no ripples or swirls whatsoever. Interestingly, this effect can be observed at room temperature and ambient pressure. 

Isn't science grand? :)

Had to put this in to show why Young was a visionary to the max.
