You are changing the floor of your perspective. A person in a tower of a disappearing train, would have a longer view of the train than a person standing on the tracks, just below the tower.
Yes, because the horizon is further away due to their greater height making the tangent that meets their eye further around.
If you were going to use perspective it would work against you.
By being up higher, you are closer to the sun, and thus it should be closer to your magic "vanishing point". As such, the sun should set earlier the higher you are.
You see, the invisible air does not make a great floor for perspective, the person higher up does not have a floor blocking their view, like the person on the floor.
And the only way that will happen is if the Earth/floor was curved. Otherwise how is a floor much lower than you and the sun meant to block the view to the sun?
It would be impossible.
You'll will never factor perspective in to your explanation. It's like, in your mind, it never presents itself as a possible explanation, does it? I know you keep using the same already refuted arguments.
Nope. It is factored in. But it can't explain it at all.
You are yet to refute a single argument, instead you keep bringing up the same refuted "refutations".
