What does uniformly dense mean in terms of what I'm putting forward?
If you mean do I feel the need to question it, then no, it's not something that needs to be high on my list.
There's less of everything the higher you go. The pyramid should tell you that.
Layers to a dome top would naturally decrease in horizontal layers if you observe the pyramid diagram.
Molecules at sea level are much more densely packed and compressed.
As I said. It's a dome and what you see on Earth under it will vary depending on where each person is standing.
It's not like you can look in the sky and immediately see a mirror image of what's in the sky much farther than you.
But you are aware the points of light do get seen in a different orientation as you go farther afield into what you think is a southern hemisphere, just as the moon reflection is shown upside down...and so on.
And atmosphere.
As in, how?
Whatever's reflected is in the realms of what we see. In my opinion.
You're simply thinking they're millions and billions of miles away and light years away and are trying to gauge stuff based on those thoughts.
The stuff these people fill us with is sci-fi fantastical but it really does beggar belief and makes me do this on a regular basis.
The horizon is simply the vanishing point to your eyes. It becomes a theoretical line or an imaginary line.
Points of light maps are fine. They help navigation around the circle under the dome.
Why should they be inaccurate?
Very possible in this Earth and even on other similar Earths outside of this one.
Maybe. If it is somehow possible.
I can think of the potential.
Not quite as primitive but you could well be on the right lines, even though it was tongue in cheek with you.
There's lots of stuff on this topic. Go through it and you'll get a better idea of what's what from my side.
