BUFFALO, you wrote
I already explained this.

Do the lights seem as though they are sinking lower? Yes, but they remain at the same height!
It's an illusion!

^Full detailed explanation here!
Was this meant to be a reply to my post? Where I dismissed your earlier post (and video) as failing to execute the experiment I described?
Once again, a proof that the world is NOT flat can be derived by watching a ship sail away from you over the horizon with a sufficiently powerful telescope. The "illusions" you describe are not illusions, but perspective. As for the vanishing point concept one of your most recent links describe, they themselves write
It has been found that the sinking ship effect effect [can be] purely perceptual, that a good telescope with sufficient zoom will change the observer's perspective and bring the ship's hull back in full view.
I don't deny that optical illusions can occur where objects at a distance can not be resolved with the naked eye. But if one actually does the experiment I described, where one observes a ship sailing over the horizon with a powerful enough telescope, there is no problem with perception. Rather, quite clearly the surface of the earth is curved, not flat.
