While reading a bunch of online articles the other day, I stumbled across an article of how humans perceive colour. It is found that colour is sort of an illusion, where light reflects off a particular object, where the arrangement of atoms contained within that object cause only some light to reflect, and for some of it to be absorbed.
However after giving this some thought for a period of time, an idea occurred to me which changed my whole perspective on how I see light.
As already outlined light is just a wave, containing photons, which travels from a light source like the sun, continues to reflect off an object, and lands in our retina, which is how the objects around us seem illuminated. However, we only think of this wave as a light wave because it is necessary for our vision, and without it the universe would be a much darker place to say the least. It is the wave which lights up the darkness, or so we perceive.
Now let me enlighten you with a story about a young boy named Ben Underwood. The significance of this story will be outlined further down, trust me. Anyway, Ben Underwood was born with a specific type of cancer, which attacks the retina, which in turn costed him both of his eyes, which had to be surgically removed at just three years old.
Most would therefore assume that Ben would not be capable of navigating around space by himself on a day to day basis for the rest of his life, and would be strictly disabled. However, Ben’s brain made an amazing adaptation, which basically allowed him to be able to see the objects around him, and eventually by the age of four, Ben could differentiate a parked car from a parked truck.
Ben developed the ability to navigate his way around life through clicking continuously with his tongue, and judging the whereabouts of objects through ricocheting sound. Ben’s brain had made an amazing adaptation, basically through trial and error, and listening to the elapsed time it took for his clicking to rebound off objects, and therefore judge the location of that object.
You might be saying ‘this is all very fascinating Jordan, but what does this have to do with whatever the hell you were talking about before, colour and light?’ Well this is where all of the ends meet.
This theory is the possibility that in the same way Ben used sound to decide the whereabouts of an object around his vicinity, our brain (specifically our eyes) has evolved to sense the whereabouts of objects through rebounding lightwaves, and what you are seeing right now is basically a picture painted by our brain to give the illusion of visual reality and light.
Therefore, our eyes are like little radar detectors for light waves, and lightwaves themselves don’t actually contain light, just a type of wave that travels through space. Our eyes have evolved to take those light waves, send that information through our brain to process and package up into a nice image so its easy for us to understand whats around us. How convenient.
Therefore the conclusion is that the universe in reality is pitch black outside the walls of our perception, the light we are seeing around us is only an illusion, which is a truely terrifying thought.
Obviously I am no scientists, and this theory is backed up by absolutely nothing, just a couple of blogs i read online. Let me know if you guys find any floors in this theory, and if you found this theory interesting.
