Those are rasterizing lines, also called sketch lines, and they’re a common occurrence in the sky. Clouds can easily form in the air when water droplets, already chilled by the atmosphere, are slightly disturbed and ionized by turbulent friction. At about that height (it can be higher in some places), you get air passing quickly against the dome that projects the sky and stars. That friction can cause the water to condense, and lightly fall, obscuring the air and essentially making fog in the air, which is what a cloud is. What’s amazing about this process is that it is a naturally occurring effect, not regulated by the weather masters that control the sky projection and the air within it. Apparently there is no concern that we will see these imperfections, and know our secret rulers are also imperfect, and that knowledge means they can be taken down so that the common man can retake his destiny and rule this flat earth, using their weather machines not to create storms but to create a utopia where there is ample food, not tornadoes and hurricanes. We can even maintain these beautiful rasterizing lines to remind us of our conquest of these creatures and the rightful assent of man. Amen.
