The Limits of Reality

What we see is less than a 10 trillionth of the light waves out there. There are thousands of cell phone conversations passing through you right now and you're completely blind to them. Snakes include some infrared light in their reality and honeybees include ultraviolet light in their view of the world. We can't sense any of these things by yourself, at least not yet, because you don't come equipped with the proper sensors.
