People who think the earth or sea is a sphere tell me this:Sea lines-horizon are arcs with very small radians-curvature.
but,If what they say is true,
I should like to know, from the point of view of a man in the middle of the sea, how, in the case of radians-curvature, the sea lines in all directions close on the spherical surface of the sea?
If this "arc" could be closed, the left and right ends of the sea line should have a pronounced twist at any observer's Angle, because the closed sea line looks like a lying circle that is an ellipse, and the two ends of the ellipse look like this.Isn't it?
I can only imagine this happening when the sea is flat, the sea is straight, and the distant object looks smaller.I really can't imagine how this could have happened if the sea was a sphere and the sea was curved.
If anyone knows, please draw a picture to explain it, although I don't think anyone knows.
By the way,I have read in Buddhist texts that the volcano is because there are six other SUNS at the bottom of the sea.
I'm sure not many people have even heard of it.So I'm just paraphrasing it.
<<<<<<<<<After thinking about it, I think I was wrong when I observed the point and horizon in the same plane.So I'm going to think about it a little bit more.So please don't reply to me any more. Thank you for your participation and giving me some inspiration.
