Fiordland National Park, South Island I
The sun appears to pour itself down and indeed its light pours in all directions, but the stream does not run out. This pouring is a linear extension: that is why the beams are called rays, because they radiate in extended lines. You can see what a ray is if you observe the sun’s light entering a dark room through a narrow opening. It’s extends in a straight line and impacts, so to speak, on any solid body in its path which blocks passage through the air on the other side: it settles there and does not slip off or fall.
