So, to return to the topic of the thread, it has been concluded that the Flat Earth has to have infinite surface area if it supposed to hold on to its atmolayer.
This means the Universe is divided into two semispaces. One 'below' the Earth (the underworld), from where the Universal Accelerator operates, and one from 'above' the Earth (the heavens), where everything we see is situated.
I draw your attention to a thread posted by 'leclerc' (
Is the Moon flat too in FE?), where 'Mr. Ireland' proposed the only possible solution to the problem which was discussed, but that can not work in an infinite Flat Earth.
Also, due to Foucault pandulum, it has become accepted to consider the Earth as rotating about a perpendicular axis through the North Pole. It seems we are a negligable distance from the center of this inifinite plane. There is also the problem of the distance from a rotating center. The greatest distance from the center is:
rmax = c/ω
where
ω is the angular velocity of rotation, because points further from this distance would have rotational velocities greater than the speed of light
c. Also, as the distance grows larger, the centrifugal tensile stress grows larger, so the Earth would tear apart (unless it is also infinitely thick, which would leave no place for the UA) from these stresses.
