The distance from which various lighthouse lights around the world are visible at sea far exceeds what could be found on a ball-Earth 25,000 miles in circumference. For example, the Dunkerque Light in southern France at an altitude of 194 feet is visible from a boat (10 feet above sea-level) 28 miles away. Spherical trigonometry dictates that if the Earth was a globe with the given curvature of 8 inches per mile squared, this light should be hidden 190 feet below the horizon.how tall is a light house? .. 25x8 is 200... thats 16 feet. thats not much fall man, look at the drain pipe of your house.. thats an inch to a foot and that doesnt even look like too much.
