Can the “end” of a rainbow be reached, or does it forever remain somewhere in the distance?
Normally, a rainbow is beyond our reach, retreating as we go toward it. It forms when light shines through specific water droplets and, through refraction and reflection, separates into colors that emerge at different angles. No two people can see the same rainbow, because they can not be in the same place; each will see color rays that come from different water droplets. In addition, a rainbow is actually a complete circle (with its center opposite the Sun), but is often cut off by the horizon (passengers in planes may sometimes see a complete circle). All that being said, there are those who attest to having reached a rainbow’s end; although these people did not find a pot of gold, they did discover a rare and special experience.
