Yes, you've shared this video before. But that doesn't change light. The sun will never go below an 8.5 degree angle from the observer. Fact. Light travels in a straight line. Fact. Ergo, light can never come at you from an angle of less than 8.5 degrees. Perspective is a visual trick of the eyes, as I showed you with your wiki's own example of flat Kansas. The ground still appears to rise to eye level right? Parallel lines converging in the distance is a visual illusion. They never converge, because they are parallel. The ground rising to eye level in the distance is a visual illusion (assuming a flat ground) as the ground doesn't actually rise to that level. The sun sinking below the horizon due to perspective, is a visual illusion on a FE. But the measured rays of light, cannot go below an angle of 8.5 degrees (more like 15 degrees for any reasonable approximation of Earth's size).
How do you know that it's an illusion that the perspective lines converge and that they do not really converge? Is it because you said the word "Fact."?
Tom, what causes the Sun and Moon to look larger when they are on the horizon? Wouldn't your interpretation of perspective preclude this? Also, I would appreciate your comments on my previous post as I do feel they point out some very obvious problems with how you try to use perspective to explain the setting of the Sun.
