“…My brother and I weren’t really “why?” kind of kids. If we asked our mother why the sky was blue, we’d get a real answer:

“The blue color in the sky is due to light rays scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. The red, orange and yellow light rays are long, so they’re not affected by the air. But the shorter wavelength light, like the blue light, is absorbed by the molecules. The absorbed blue light radiates in different directions. It gets scattered all around the sky. Since you can see the blue light rays scattering from everywhere overhead, the sky looks blue.”

If you got that answer as a child, you’d never ask why again. “
