What are those floaty things in your eye Michael Mauser

Have you ever noticed something swimmingin your field of visioné It may look like a tiny wormor a transparent blob, and whenever you try to geta closer look, it disappears, only to reappearas soon as you shift your glance. But don't go rinsing out your eyes! What you are seeing is a common phenomenon known as a floater. The scientific name for these objectsis Muscae volitantes,

Latin for quot;flying flies,quot; and true to their name,they can be somewhat annoying. But they're not actually bugsor any kind of external objects at all. Rather, they exist inside your eyeball. Floaters may seem to be alive,since they move and change shape, but they are not alive. Floaters are tiny objectsthat cast shadows on the retina, the lightsensitive tissueat the back of your eye.

They might be bits of tissue, red blood cells, or clumps of protein. And because they're suspendedwithin the vitreous humor, the gellike liquidthat fills the inside of your eye, floaters drift alongwith your eye movements, and seem to bounce a littlewhen your eye stops. Floaters may be onlybarely distinguishable most of the time.

They become more visiblethe closer they are to the retina, just as holding your hand closerto a table with an overhead light will result in a moresharply defined shadow. And floaters are particularly noticeable when you are lookingat a uniform bright surface, like a blank computer screen, snow, or a clear sky,

where the consistency of the backgroundmakes them easier to distinguish. The brighter the light is,the more your pupil contracts. This has an effect similarto replacing a large diffuse light fixture with a single overhead light bulb, which also makesthe shadow appear clearer. There is another visual phenomenonthat looks similar to floaters but is in fact unrelated. If you've seen tiny dots of lightdarting about

when looking at a bright blue sky, you've experienced what is knownas the blue field entoptic phenomenon. In some ways,this is the opposite of seeing floaters. Here, you are not seeing shadows but little moving windowsletting light through to your retina. The windows are actually causedby white blood cells moving through the capillariesalong your retina's surface. These leukocytes can be so largethat they nearly fill a capillary

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
