>>12629203Quoting another post I saw here: The flat Earth is refuted by the measurement of “how far can I see from a tower”, the law being that the distance the square root of the product of the height of the tower and the radius of the Earth. This law extends from ship mast-towers of 20 meters, where you can see about 10km to airliners at 10 km, where you can see things up to 250 km away. The law is very easy to check today, and it can be done by anyone from a local mountain.
I haven't tested this yet, sounds like fun, give it a try if you care.
