Is Your Red The Same as My Red

Hey, Vsauce. Michael here. This appears blue. This appears yellow.And this appears green. Those of us with normal color vision can probably agree.But that doesn't change the fact that color is an illusion. Color, as we know it, does not exist in theoutside world, beyond us, like gravity or protons do. Instead, color is created insideour heads. Our brains convert a certain range of the electromagnetic spectrum into color.I can measure the wavelength of radiation, but I can't measure or observethe experience of a color inside your mind. So, how do I know that when you and me lookat a strawberry, and, in my brain, this perception

occurs, which I call quot;red,quot; that, in yourbrain, a perception like this doesn't occur, which you have, of course, also learned tocall red. We both call it red. We communicate effectively and walk away, never knowing justhow different each of our internal experiences really were. Of course, we already know that not everybodysees color in exactly the same way. One example would be color blindness. But we can diagnoseand discuss these differences because people with the conditions fail to see things that most of us can. Conceivably though, there could be ways ofseeing that we use that cause colors to look

differently in different people's minds, withoutaltering their performances on any tests we could come up with. Of course, if that were the case, wouldn'tsome people think other colors look better than othersé Or that some colors were morecomplimentary of othersé Well, yeah, but doesn't that already happené This matters because it shows how fundamentally,in terms of our perceptions, we are all alone in our minds. Let's say I met an alien from a far away solarsystem who, lucky enough, could speak English,

but had never, and could never, feel pain.I could explain to the alien that pain is sent through A delta and C fibers to the spinalchord. The alien could learn every single cell and pathway and process and chemicalinvolved in the feeling of pain. The alien could pass a biology exam about pain andbelieve that pain, to us, generally is a bad thing. But no matter how much he learned, the alienwould never actually feel pain. Philosophers call these ineffable, raw feelings quot;Qualia.quot;And our inability to connect physical phenomenon to these raw feelings, our inability to explainand share our own internal qualia is known

as the quot;Explanatory Gap.quot; This gap is confrontedwhen describing color to someone who's been blind their entire life. Tommy Edison has never been able to see.He has a YouTube channel where he describes what being blind is like. It's an amazing channel.In one tutorial he talks about colors and how strange and foreign of a concept it seemsto him. Sighted people try to explain, for instance, that red is quot;hot,quot; and blue is quot;cold.quot;But to someone who has never seen a single color, that just seems weird. And, as he explains,it has never caused him to finally see a color. Some philosophers, like Daniel Dennett, arguethat qualia may be private and ineffable simply

because of a failure of our own language,not because they are necessarily always going to be impossible to share. There may be an alien race that communicatesin a language that causes colors to appear in your brain without your retina having tobe involved at all. Or without you having to have ever needed to actually see the coloryourself. Perhaps, even in English, he says, given millions and billions of words usedin just the right way, it may be possible to adequately describe a color such that ablind person could see it for the first time. Or you could figure out that, onceandforall,yes or no, in fact, you and your friend

What Are Eye Boogers

So, Mr. Sandman, I asked you to bring me adream, and you brought me these gross eye boogers. Ok, but, what actually is this goopy junkthat gathers in the corners of my eyes while I'm asleepé You might know it as eye boogers, sleepies,dream dust, sleep sand, or the sleep in your eyes. Scientists actually don't have a standardtechnical term for this crusty eye residue, but some call it gound or rheum.

Which is much less fun to say. Rheum is a term for any thin discharge thatcomes from mucusy parts of your body, like your eyes and nose. The kind that comes from your eyes is madeup of all kinds of junk, like mucus, dead skin cells, oil, dust, and bacteria. This delightful mixture gathers and driesto form a crusty residue in the corners of your eyes after you've been snoozing fora while. But then, why do eye boogers only seem tobuild up when we're sleepingé

Well, it turns out that gound or at leastthe things in it is kind of always there. You just don't know that it's there mostof the time. Your eyeballs need to be kept nice and wetto function, so they're protected under this watery coating called a tear film. A tear film actually has a couple of parts:an inner layer of watery mucus that coats your cornea and keeps your eyes lubricated,and a thin oily layer on top to keep all that moisture inside. So normally when you're awake, any crudthat gets in your eye is washed away by this

tear film whenever you blink. Your eyelids are a lot less active when you'reasleep, though. When you close your eyes for the night — oreven just for a nap — you stop blinking, which means you're not clearing out allthat debris. So it builds up, along with some of the mucusand oils from your tear film, and collects in the corner of your eye. And, before you know it, you have eye boogersin all of their crusty, cruddy glory. Some gound is dry and crumbly, and some iswet and sticky it all depends on what's

in your tear film. For example, people who have allergies tendto rub their eyes or produce more eye mucus, so there's more gunk floating around, whichmeans goopier eye boogers. Gross, yes. Dangerousé Not usually. But excessive eye boogers can be a sign ofa more serious health problem. People with certain eye conditions, such asoveractive oil glands or blocked tear ducts, can have more eye discharge and residue buildup. And with some infections, like pinkeye, thegunky buildup can get so bad that people can't

open their eyes in the morning! Those are some strong boogers. But don't worry for the vast majorityof people, gound is normal and harmless.
