Tom Bishop, do I correctly understand your position?
"Celestial navigation is allegedly based on the theory that the Round Earth is the center of the universe and that everything is revolving around it."
Where did you get that? Completely wrong. Please take a course in elementary astronomy. You don't have to believe it, but we have to talk about the astronomy taught in school, in textbooks, all over the net, not your straw man version based on quotes from pre 20th century obscure scientists. We are RE, we get to say what RE is today, and that model is consistent all over the place, schools, textbooks, internet, astronomers, gps engineers, celestial navigation.
Epicycles, from the wiki page:
Epicycles worked very well and were highly accurate, because, as Fourier analysis later showed, any smooth curve can be approximated to arbitrary accuracy with a sufficient number of epicycles. However, they fell out of favour with the discovery that planetary motions were largely elliptical from a heliocentric frame of reference, which led to the discovery that gravity obeying a simple inverse square law could better explain all planetary motions.
I searched looking for contemporary astronomy using epicycles, but after many pages, I could find only Ptolemy, Copernicus, Aristotle, all history telling the story of how Kepler came up with a better explanation. Zero contemporary references to epicycles. Explained here:
https://www.spitzinc.com/blog/epicycles-and-discovering-bad-theories/As I asked earlier, do you understand RET? Apparently not, the first step is to agree on what RE is, and since you are not RE, yu don't get to say what it is. It is what textbooks and science teachers and diagrams all over the internet say it is today, not some obscure 19th century scientist.
Tom Bishop gets to say what FE, or more precisely, the Tom Bishop version of FE (there are many, and they conflict). So what can you say? So far, I got no map, "anomolous winds", "unknown forces". To make your idea work, you must insist that no one knows the distances between places and apparently never can.
Tom Bishop, does gps work? Does it accurately tell you and billions of others where they are all the time? Even if there are no satellites because the earth is flat and gps is faked by NASA, it still produces accurate location data (or do you think gps fails constantly?) World maps with locations of ships over all oceans shows their locations as reported by gps. This is all wrong and no one notices?
How can ships and planes have gps and not know their locations and therefor distance, even over ocean? If the distances are as advertised, why can't you make a flat map? If the distances are not as advertised, how can ships and planes arrive where they intended and when they intended?
