Basically, you got to throw away the last two centuries of (mathematics, invisible as usual), physics and geodesy to believe in this osmium-grade bullshit.

Funny ain't it ?

That is why you gotta be totally numbed down (or literally have fucked-up your own brain with drugs, e.g.) to even be able to think in this direction.

You can see with your own eyes that the earth isn't flat:

Just watch the horizon line over a planar hand-rail at the sea side. You can see the curvature of the earth when the rail is planar horizontally and long enough. Because the horizon line and the rail diverge more and more when looking more to the left or more to the right, so to say.

I believe to be able to make some very dim sense from satellite orbits in this context you can observe at night you'd have to "find" a completely "new" (<- bullshit, most likely to expect) "theory" of gravity first.
