What happens to the flame when a candle is blown out? Where does it go? This is an image, in the form of a question, that my mind always invokes when people talk about a "soul" that still exists after a person's death. Spiritual abracadbra follows. I am interested in, rather naively, is a physical explanation. Despite everything I have read about fire and flames, including Michael Faraday's legendary Christmas lectures on fire, it is one element that still strikes me as mysterious. Any answer? :)
