Hey,
I came to this site via a youtube-video and have been lurking in this forum for a while. At first, I was astonished by the fact that there are still people who believe that the earth is flat. Then I realized that you do have a valid point - I did never question the shape of the earth, I believed it was spherical as I was taught. That does not change the fact that it is, indeed, spherical, but the idea of questioning established models and looking for alternatives is quite interesting to me.
I finally registered, because I had some nagging questions about your model and noone posted them before (or at least I could not find them).
About myself - I am a 24 year old student writing my master's thesis in mathematics (minor physics). My main field of study is (algebraic) topology, but if you want to discuss dynamical systems or differential geometry, I'm all yours.
I do not hope to convince any flat-earther on this forum (if you do believe in a flat earth despite all evidence and obervations already explained in other posts, I will not be able to convince you), but I enjoyed reading the discussions and I hope to have even more fun participating in them.
