Hello,
I stumbled onto your interesting board recently. I find it fascinating that a small group of people maintains this idea in the face of an overwhelming majority opinion to the contrary. I can see from the signatures on this site that this fact (opposition to a mainstream point of view) is in fact a point of pride among some of you. In any case I see that you all have devised a relatively detailed model for your hypothesis accounting for many points one would raise.
One of the points addressed in the FAQ is the question of the sunrise and the sunset. Let's just focus on the sunset for ease of communication. In the round earth model, the sunset is a result of the earth rotating "away" from the sun, such that the observer becomes separated from illumination by the body of the earth. The lowering of the angle of the sun in the sky is a result of the same rotation.
Now, from your FAQ:
"A: It is a perspective effect. The sun is just getting farther away: it looks like it is disappearing because everything gets smaller, and eventually disappears as it gets farther away.
UPDATE:The theory of Electromagnetic Acceleration is currently being developed and reviewed by members. Once completed, Electromagnetic Acceleration will be used as an alternative in explaining sunrises, sunsets and horizons for the dark energy model only."
I'm only going to address the first model because the electromagnetic acceleration bit is not elaborated.
The suggestion in your model is that "it is a perspective effect." Now, I have two complaints about this interpretation I hope you will take seriously.
First, the declining angle of the sun in the sky.
As the sun sets (or moves away, as you may prefer...), its angle in the sky declines. We can all agree on this. At noontime in the summer the sun is directly overhead, then as the day goes on it goes "down" across the sky toward the horizon. We can reconcile with your model easily. If the sun is an object relatively close in terms of distance from the surface (I'm accepting your model for what the sun is, and how far it is - for the sake of this question), then as it moves away it will in fact appear to "descend" in the sky as it moves further away. Some pencil and paper sketches should make this apparent.
Now, there seem to be some problems with this. First, if the sun is moving away, why does it not appear to grow smaller, but rather maintain its size?
Second, if I am in an airplane or on a tall mountain at sunset, I can see the sun setting below me. Your model of the sunset allows for the sun to appear nearly in the same plane with my line of sight (an angle of 0 degrees if you like) as its distance approaches infinity. However, no matter how distant the sun is, it cannot descend below the plane of my sight if it is truly above my head. How do you account for this piece of observational data?
Now, the second complaint: Why does the sun gradually become blocked by the horizon, instead of simply fading away? Please again consider a situation where you are a significant distance above the land, so that simple occlusion by trees and such would not be the issue.
I have some more things I think are not quite right with your model, but I would rather present a few questions at a time. I appreciate your time. And while I think your model is wrong, please understand that I do respect your right to believe what you will.
Thank you.
EDIT: Actually, I think I would like to include one more complaint. I'm not sure if this is valid in your model since I have noticed you have very different ideas about basic phenomena like gravity. So I'm not sure you have the same ideas about white light being composed of multiple wavelengths which account for different colors, or if you accept that the atmosphere can scatter light to change the apparent color of the sun. But I will present it anyhow:
When the sun sets, the sky turns a beautiful shade of red and pink due to increasing amounts of blue light being scattered away by the atmosphere. We all see this effect. Now, as the sun dips below the horizon, the pink light gradually retreats with it. However, objects at high altitudes, such as clouds and planes, still reflect the pink light from setting sun. It is as if they are being shone on "from below." This could not occur in the flat earth model. So please, address this as well.
