what is the meaning of there is a light that never goes out
There Is a Light That Never Goes Out AllMusic's Tim DiGravina argues that while depressed characters were a regular feature in Morrissey's work, his lyrics on "There Is a Light" "ups the sad-and-doomed quotient by leaps and bounds."[6] Goddard argues in his book Songs That Saved Your Life that the basic narrative story is similar to that of the James Dean film Rebel Without a Cause, in which Dean—an idol of Morrissey's—leaves his tortuous home life, being the passenger to a potential romantic partner. In fact, a line from that movie ("It is not my home") is quoted in the song. According to Goddard, an earlier version lacked some of the finished version's ambiguity, culminating in the line "There is a light in your eyes and it never goes out".[7]
Speed of light Empedocles (c. 490–430 BC) was the first to propose a theory of light[116] and claimed that light has a finite speed.[117] He maintained that light was something in motion, and therefore must take some time to travel. Aristotle argued, to the contrary, that "light is due to the presence of something, but it is not a movement".[118] Euclid and Ptolemy advanced Empedocles' emission theory of vision, where light is emitted from the eye, thus enabling sight. Based on that theory, Heron of Alexandria argued that the speed of light must be infinite because distant objects such as stars appear immediately upon opening the eyes. Early Islamic philosophers initially agreed with the Aristotelian view that light had no speed of travel. In 1021, Alhazen (Ibn al-Haytham) published the Book of Optics, in which he presented a series of arguments dismissing the emission theory of vision in favour of the now accepted intromission theory, in which light moves from an object into the eye.[119] This led Alhazen to propose that light must have a finite speed,[118][120][121] and that the speed of light is variable, decreasing in denser bodies.[121][122] He argued that light is substantial matter, the propagation of which requires time, even if this is hidden from our senses.[123] Also in the 11th century, Abū Rayhān al-Bīrūnī agreed that light has a finite speed, and observed that the speed of light is much faster than the speed of sound.[124]
