I need to put a image for delivering my point. See image below: https://i.cubeupload.com/z8ybaR.jpeg According to Welleim2 and Buluncore, horizon forms a perfect circle centered on the observer for a perfect sphere. let's assume Earth is a perfect sphere. So horizon must have a curve to x,z...

So i was right and Willem2 was wrong? After all a new problem is coming in my head. Willem2 told all point of horizon will be at the same distance for a flat terrain, so they form a circle. what about a planet? if it is same for a planet, another problem rises up here: Horizon has two curves...

Horizon has a dip in a planet but it hasn't any dip in a plane. so they have a totally different mathematics. the d = 3.57√h is a approximating equation for a planet not a plane . If I made a mistake, correct me. After all, I actually want to know is there any formula for calculating distance...

Why? Why you used a circle rather than a triangle? Willem2 supposed Earth is round then he calculated distance of horizon and length of it. I don't want to suppose anything i see horizon is a straight line so let's calculate for a plane: i know Earth is round but i want to calculate for another...

Where does the 12.45*sqrt(h) come from ?

How much is the length of horizon that human's eye can see at sea level? How much is the length of horizon that human's eye can see at higher level? any formula? I am not sure i should use wide or length. i mean the rightest point of horizon to the leftest point of it for human' eye angles.
