As for the purpose of this page: imagine if a government, or a fact-checking company, had to rate every possible statement or text, not necessarily just as "true" or "false", the answer may be more nuanced than just that, but the task is to provide factually true context for the reader. I am no expert, so I may get things wrong, so keep in mind this is an amateurish attempt! I'll also do research and maybe I'll learn new things, lol. For visual clarity, the text is introduced with a bold blue "text" writing, whereas the note will be introduced in bold red.
Text: the sky is green.
Note: this information is false on planet Earth. The sky on planet Earth can have three main colors: blue during daytime with clear skies, grey during daytime with overcast skies, and black during the night. There may be other colors such as orange during sunset, or after a sandstorm, but the sky on planet Earth is never green, and neither is the sky of any celestal body in the Solar System. Some exoplanets may have a green sky, but this text is misleading.
Text: Imaginary friends don't exist.
Note: this text is vague. Imaginary friends don't exist in a physical sense in the same sense as a physical human being, but they can be imagined, and doing so may have some kind of psychological effect on the person imagining it, making their "existence" not necessarily negligible.
Oh gosh, I just realized that fact-checking is not as easy as it may seem, lmao. Fact-checking in Demichronia is harder than it seems! I'll try with more sentences eventually, maybe even entire texts!
