What Are We Unaware Of?

Under the water, a fish swims peacefully, unaware of the dangers that lie above. The fish knows only its own environment, without any awareness of the world above the water. All the fish knows is the water. Moving in a three-dimensional environment, the fish can go up, down, right, left, forward, or backward. But it is ignorant of the fact that outside the water, there is another world—a world with predators watching the fish and waiting for the right moment to strike. I love this photo because it makes me think: what are we humans unaware of?

This photo is best appreciated in large displays.
