This is the IQ distribution curve doing what it does best: making everyone uncomfortable. On one end, you've got the blissfully simple "the sky is blue" crowd. On the other extreme, the galaxy-brain folks who think "air is blue" (which, no—air molecules don't have color, you absolute goblins). And there in the middle? The insufferable physics majors who need everyone to know about Rayleigh scattering. For those mercifully unfamiliar: Rayleigh scattering is why shorter wavelengths of light (blue) scatter more in the atmosphere than longer ones (red). So yes, the sky appears blue because of how sunlight interacts with atmospheric particles—not because oxygen and nitrogen are secretly blue crayons. The real kicker? Both extremes arrive at "it's blue" while the middle suffers through the actual explanation. Sometimes ignorance and advanced stupidity achieve the same result, just with vastly different levels of confidence.
