Laugh all ya want but the fact is sextants are used by people who hold both beliefs globe and flat for hundreds of years. You were too retarded to make that simple connection.
hold both beliefs globe and flat for hundreds of years.
you can "believe" whatever you want ... :)
Just like "flat earthers" can believe whatever they want, but the internet will still works for them - even though the internet was built with "science".
Man watch some celestial navigation videos, you have it completely inverted. How do I know? Cause I've been a licensed mariner my entire adult life. When you use a sextant you view a local apparent horizon, and the zenith is straight overhead. You have to correct your observation to get a celestial horizon. This forms a 90° angle (flat earth horizon) which you use to calculate the local apparent altitude of a star.
Whether you are on a globe or a plane you would still have to make corrections to form a 90° angle with the celestial horizon and zenith. If you are on a flat earth it's because of your height of eye over the ocean and potential atmospheric distortion. If you are on a globe it's also because of earth curve. BUT EARTH CURVE IS NEVER INCLUDED IN CELESTIAL NAVIGATION CALCULATIONS. Your corrections assume a plane dipshit.
The sextant wasn't invented until like 2000 years after Aristotle. I think what you are referring to is the Eratosthenes experiment with pillars and shadows in two different cities that 'proved' a sphere. Unfortunately you can produce the same results on a plane with a local light. I can show you with two beer bottles and a light bulb, so this effect fits the flat earth model.
It was literally geometry that first clued me in to flat earth. As a Mariner I would sometimes do earth curve calculations to see when an object like a lighthouse or drilling rig should come into view. And I kept seeing them so far off, with such clarity that refraction couldn't explain it. It was as if there was no curve that you would expect on a planet of 24,901 miles in circumference. Then finding out nasa fakes everything finally got me to investigate flat earth.

let me restate:
the sextant uses geometry (which Aristotle used to "prove" a globe, but whatever)
i thought flat earthers didn't believe in geometry.
am i wrong about that ?
