I wonder what would it look like to a camera if in an otherwise completely dark room, a very bright singular point source of light were to shine at the floor from 100 feet in the air. Then about 70 feet up or so a colorful (facing downward) large disk was to slide over and in front of the point source of the light. Would the underside (downward facing) of that object have clearly visible color? No, it would be dark to our eyes as it moved over the point source. When the light source is completely covered, looking up would again reveal no detail on the object covering the light source. As it moved away revealing the light source again, there would be no detail revealed of the object that covered the light source.
How is it so difficult for people to understand these things with the orbits of the sun and moon and earth and how shadows work out for us on the ground every so often.
