Yesterday when I was listening to David Gray’s Flame Turns Blue on Youtube, I read the poster’s description for the clip and found it interesting:
The Greeks had theories about the four elements: Earth, Air, Water, Fire. In these theories they eventually tried to also come upon theories of the unifying element, the element, or thing, that everything was made of. One of these theories was about the exact place in a flame where it turned blue, that exact place was where the unifying element in the universe ‘lived’ for lack of a better word. I wonder if David knew about this, and hence this song’s title and theme, maybe not. We now explore String Theory, and M Theory, looking for the very same unifying element, thing, to the universe.
