![]() ![]() ![]() Nor do we observe minimum sun angles of 16 degrees. 90 degrees is consistent with the Globe model, of course - so thanks for that confirmation (!) (16 degrees above the horizontal), not the 90 degrees from the zenith that you use in your explanation. and one finds that the sun angle at the "poles" will be on the order of 74 degrees from the zenith Plug those values into any triangle calculator, By using typical FET values for Sun altitude and for Earth disc radius, we can calculate what the Sun's angle would be for an observer at the North Pole according to FET. The only way to have the Sun at 90 degrees to the zenith at the North Pole (within FET) when it is at zenith for an observer at the equator is for disc radius of the flat earth to be infinite. The above definition of Latitude proves Flat Earth Theory wrong. I notice there is a dismissal among flat Earthers of any historical accounts like this yet when it comes to those ancient flat Earth maps they are quite happy to use those as 'evidence' to support their claims. It is only flat Earthers who have erroneously concluded that the Earth is flat. Unlike flat Earthers who twist those conclusions to suit their beliefs. Rather he used observations to reach conclusions as any scientist should. ![]() As one of the greatest thinkers of his time, I don't think Eratosthenes erroneously assumed anything. So it was natural to conclude that if there are shadows being cast at one latitude but not at another latitude on the same date and time, then the Earths surface must be curved. ![]() Aristarchus had already concluded that the Sun was much further away from the Earth than the Moon based on his observations of the phases of the Moon and the angular separation of the Sun and Moon at different phase points in the cycle.Įratosthenes also concluded that light rays from a distant Sun must arrive at Earth along parallel paths. But actually Eratosthenes concluded that the Earth must be round, based on the evidence available to him. ![]()
