A rainbow has no fixed location in space. It is an optical effect created when sunlight interacts with raindrops and reaches an observer at specific angles. Because the cone of colored light is centered on the observer's eyes, each person sees a different rainbow. There is no physical end point that everyone can walk to. The appearance of the rainbow depends on the observer's position, showing that some phenomena exist only through the interaction between nature and the person observing it. Source: Cowley, Les.
