A friend recommended I read Einstein's 1905 papers. I must admit I only grasped a little of it, and only because I came at it backward (catching the cliff notes in years prior). He did mention something important before recommending it though: light has no mass. This struck me as odd. In a paper focused and built so heavily on symmetry, to have this exception seems odd. Light has energy, which has a mass equivalent according to the paper, but for some reason light is an exception to this rule. Stranger still to me, experiments have verified this. This means either light is something in the universe that need not follow the rules of everything else, or that we lack something required to accurately identify how it does follow these rules, experimentally. What is stranger still is that much like other assumptions in prior generations of far reaching theories, light being massless seems to be commonly accepted. Most likely this is because the genius presenting the equation indicated ...
