They also dismissed all the evidence that shows the Earth is round, just like Earth's photographs from outer space. According to them, it is nothing more than a conspiracy engineering advocate that the Earth is round governed by the US Space Agency (NASA) and other government agencies.
One of their leading theories calls the Earth a similar disk, where the Arctic Circle is at its center, while Antarctica, an ice wall 150 feet or 45.7 meters high, is on its edge.
They claim, NASA employs a number of people to keep these ice walls tight, preventing anyone climbing them and falling off the earth's disks.
While the Earth's day and night cycle is described as follows: The Sun and the Moon are spherical objects of 51 kilometers in diameter, which spin at 4,828 kilometers above the flat Earth.
Like the spotlights, the sky balls illuminate different parts of the planet in a 24-hour cycle. Proponents of this theory also believe there is an invisible object called "antimoon" (anti-Moon) which is responsible for obscure the shape of the Moon, into a crescent moon for example.
Furthermore, for them, Earth's gravity is nothing but an illusion. The attractiveness of the earth, they say, does not speed things down, but it is the Earth's disk that accelerates the motion of 9.8 meters per second squared, driven by a force called "dark energy."
The Flat Earth Society's way of thinking follows the way of "Zetetic Method", an alternative scientific method developed in the 19th Century.
"Essentially this method emphasizes reconciliation between empiricism and rationalism, and makes logical conclusions based on empirical data," said the deputy chairman of the Flat Earth Society, Michael Wilmore of Ireland on the science site Life's Little Mysteries.
Their details may be ridiculous and like a joke, but its supporters really consider it to be a more sensible model of astronomy than can be found in textbooks
A simpler way of saying this is, FE people are building a religion for themselves. It happens to be a religion built around something that is different than the spiritualism of most religions.
