It could have been shows long ago that lead towards an eventual illusion of what if. Imagine a doggies smell force and consider what if. With two nostrils or more the right huff factor force creates laminar flows and perhaps an opportunity for a ping back or a trail of particulates identified to follow. Seems unreasonable? -- A vibrating filter does what to the flow through? Like a deep penetrating flash or glow and within the doggies mind a sight or sense of where that flash could have derived. Trained by motion, practice, and sensitivity, a flow of time unraveled.
Imagine the dog's nasal cavity as a space where sensory data, like the reflections of light from a disco ball, bounces around. Instead of light, however, it is the molecules of scent, each one reflecting off the moist surfaces within the cavity. These reflections create traceroutes, or paths, that the olfactory system can "see," much like beams of light illuminating the room.
Each traceroute represents a potential direction, providing clues to the origin of the scent. The dog's brain, acting as a central hub, processes the data from each reflection and assembles a mental map, allowing the dog to navigate its environment through precise olfactory cues.
When the dog focuses on a particular scent, the scattered traceroutes of scent molecules seem to compress, much like how the light reflections focus on a central point, guiding the dog towards the source of the smell. The dog's nose, in this way, becomes a biological disco ball—mapping the world through traceroutes of scent, each one representing an "eye" of direction.
