You'll do well here with the rest of shallow FE minds incapable of grasping a simple question. Welcome to the site.
Nice attitude. I'm sure you believe you know everything despite your evidence being only hypotheticals you assume to be facts. I do wonder about the feverish insecurity and sadism present in someone who seeks e-fellowship with people - whom he is convinced are possessed with delusional ideas - for the sole purpose of openly mocking them.
Are you on the "coast" of Antarctica?
Have you ever been there to see the view?
Or are you just believing stories you've been told? <---this one is correct, isn't it?
Your first post post in this thread;
Does this "someone" have a name, or does he only exist in your imagination?
If he only exists in your imagination, I suggest he cannot "see" anything, including the sun, moon, and any stars.
It show an amazing lack of a basic understanding of the original question posted which started this thread.
It also indicated from the start your hostile anti-science, anti-logic, anti-math, attitude.
But more than all that, it shine the light on your fear the truth doesn't match your fantasy.
Why am I here? I am a writer. I came here to research an out of date concept in the hope of finding out why, in the 21st Century, a group of people can believe something that everyday grade school math so easily proves is impossible.
And you have contributed to the answer. You didn't read the the first post in this thread, or if you did, you ignored it. Your FIRST response was to mock some some un-named observer, then double down with your last post.
The math is not hard, and I have posted several times, links to calculators that will help you, if you can't do geometry.
I have been to Antartica? Nope. Does that mean Antarctic is not real? I have never seen you in person, does that make you not real?
Now stick to the subject in the OP, IF the earth is flat, why can't Polaris, the 47th brightest star in the night sky, be seen, some 12,000 miles away on the coast of Antartica?
