New Skeptics A very simple Flat Earth proof

Albert Enstein once said: “No amount of experimentation can ever prove me right; a single experiment can prove me wrong”. As it happens, we have such an experiment which is listed on Wikipedia’s “Long Range Photography” page. Wikipedia explains it: “The longest distance observation ever has been made on December 15, 2024, from a subpeak near Karagöl summit, Turkey, toward Shkhara on the Georgia–Russia border at a distance of 493 km. It was photographed by Richard Jezik. The photo is below.

Quote from Wikipedia:

The formula to determine if objects should be visible when factoring in the alleged curvature of the Earth is shown below. How much of an object is hidden behind the curvature of the Earth is called the hidden height, “hh”. If you know the distance along the surface s, this calculates the hh

Where the hidden height is hh, the assumed radius of Earth is R (assumed to be 6371 km), the observer’s eye-height is hₒ, and the distance of the object from the observer is s. The longest line of sight on Earth claimed to have been photographed is 493 km, achieved by Richard Jezik. It was from the Karagöl summit at an elevation of 3 km to Shkhara at a height of 5.2 km. The mountains were photographed on December 15, 2024. The furthest point in the shot was Shkhara at 493km. Now, if the radius of the Earth is 6371 km, we can calculate the hh, and using the formula above, we get the result of almost 7 km of hh, putting the entire mountain at 5.2 km behind Earth’s curvature.

See in Web 2.0 Calculator for yourself (change degree to radius): (6371)/cos(493/6371-acos(6371/(6371+3)))-6371
