Liquid Light
While light is not a liquid, could one say it flows? It has a speed, after all. And it can bend in heavy gravitational fields.
But what would light flow within? Time? One the peculiar things about electromagnetic radiation (photons by another name) is that though we can time light, light itself cannot be said to experience time. Relatively tells us that accelerated to the speed of light, a clock will stop ticking. At the speed of light — no time.
What does it all mean? I wish I knew.
