These days, kids identify them by the aspect ratio.

What are cis and trans alternate types of? I don't think it's "gender identity" because wouldn't that just be man, woman or nonbinary regardless of whether they're cis or trans? Cis/trans just being a qualifier?

If the answer is "I am cis" or "I am trans", what is the question?

Edit: Someone came up with the term "gender congruity" and (after looking up the definition of "congruity") I think this describes what I'm talking about perfectly.

We know what causes magnetic fields and we know what their effects are, but what actually are they? What does it mean for them to be composed of "lines of force"? What is the mechanism of that force? What is actually going on in a magnetic field that the space outside of a magnetic field lacks?

This is getting hilarious

The moon rotates once per revolution around the Earth, but that's not a coincidence. Somehow the rotation and revolution are connected to each other. Some force is keeping them the same. How exactly does that work?

Besides Reddit and Fediverse sites, how much do people know about what is going on?

I bet not much.
