Light, to me, will always carry a sort of mystical quality, regardless of how great our understanding of it grows to someday be. It travels across the cosmos carrying tantalizing hints at what lies beyond our short grasp. It is the information super highway of the Universe, bringing information and description of what else exists across time and space so that we may know just how much there is left to learn in regards to heavenly bodies. I suppose much of it can be chalked up to human ingenuity; the analyzing of spectra to determine chemical composition is not intuitively suggested by light, and the amount of work and creativity put into telescopic and imaging technology should never be taken for granted. This being said, these observations and advancements (among most other things) would be near inconceivable without the presence of light. In the past century, with Einstein’s theory of relativity and its implications, light has become even more essential to our understanding of the fundamental nature of the Universe. Light is the building block of everything else; life, the creation of mass, the formation of the Universe. Understanding and applying our knowledge of light seems to me to be the most promising and interesting scientific task. How could it not?
