Wow. You didn't understand what I drew at all. If I really drew higher at farther away, wouldn't it look like a U?
And as pointed out before, that, that is really what you need to get the effect that is observed, as well as some magic to then pull the bottom of that U to eye level.
With your fantasy, things should disappear from the top down as they leave the dome.
You guys are dishonest down to a fundamental level of what you see.
Quite the opposite.
You are so dishonest you entirely what is said and respond with nonsense.
The text you were responding to was discussing how as you get higher, the horizon gets further away.
So what was that drawing meant to convey, if not that?
And why did you provide that crap in response, rather than providing something to illustrate the horizon getting further away as you get higher?
I can't draw now cuz Kindle
Wait until you can, because your word based descriptions are horrible.
What we know is that with your parabola limiting your vision to 5km, there is no reason to be able to see further as you get higher.
Why should the parabola get higher, rather than you just moving closer to the top of the parabola?
What magic gives your parabola its size and distance?
And we also know a RE does give the expected result, as has been explained to you repeatedly.
With a spherical Earth, the horizon is merely the location where a line of sight from your eye to Earth is tangent to Earth.
If you get higher, the tangent gets further away.
