On the relativity of lengths

  1. Jul 30, 2005 #1
    when i look at the hour-hand of my analog watch move, which it appears as if it is not moving, it is as if i am looking at a ray of light move at the speed of 2.99792458E8 meters per second a distance of 1.29510341856E13 meters, relatively speaking. in other words, the distance around my analog watch, for the hour-hand of the watch, is as if it were 1.29510341856E13 meters around if the hour-hand of the watch were a ray of light. 1.29510341856E13 meters is the distance a ray of light covers in 12 hours.
