I know this is probably going to sound incredibly moronic and stonerish, but has anyone looked directly at the sun (behind a thin cloud so you can actually see its full form), and noticed that NOTHING else in nature or the man-made world looks as unbelievably, perfectly circular as the sun? Sure, you can manufacture a mathematically perfect circle, but it still doesn't compare, somehow. It's like you haven't seen a real circle until you've looked at the sun.
