As an example of how the Flat Earth Society controls opposition, just look at this Vice.com interview with them and see how the misinfo psy-op works:
Yes, There are Still People Who Believe the Earth is Flat
For example, see the answer given for seeing different stars in different places on Earth:
“We all know some stars are visible from the Southern Hemisphere and not from the Northern Hemisphere, but the reason behind that is electromagnetic and optical acceleration through an aetheric whirlpool. We believe in cosmic speed, but in an esoteric sense.”
What the hell are they talking about!? “Electromagnetic and optical acceleration through an aetheric whirlpool? Esoteric cosmic speed sense?” It’s purposeful, pointless word salad to discredit the flat Earth message. The real reason, as given by the man whose work they’re claiming to represent, is as follows:
“What can be more common than the observation that, standing at one end of a long row of lamp-posts, those nearest to us seem to be the highest; and those farthest away the lowest; whilst, as we move along towards the opposite end of the series, those which we approach seem to get higher, and those we are leaving behind appear to gradually become lower … It is an ordinary effect of perspective for an object to appear lower and lower as the observer goes farther and farther away from it. Let any one try the experiment of looking at a light-house, church spire, monument, gas lamp, or other elevated object, from a distance of only a few yards, and notice the angle at which it is observed. On going farther away, the angle under which it is seen will diminish, and the object will appear lower and lower as the distance of the observer increases, until, at a certain point, the line of sight to the object, and the apparently uprising surface of the earth upon or over which it stands, will converge to the angle which constitutes the ‘vanishing point’ or the horizon; beyond which it will be invisible.” -Dr. Samuel Rowbotham, “Zetetic Astronomy, Earth Not a Globe!” (230-1)
The horizon is not the end of the heavens, it is merely the vanishing point of your perspective, so different stars are visible and appear at different inclinations wherever you are in the world. In fact, the range at which people all over the Earth are able to see the same stars does not fit with the globular model. For instance, Ursa Major, very close to Polaris, can be seen from 90 degrees North latitude (the North Pole) all the way down to 30 degrees South latitude. The constellation Vulpecula can be seen from 90 degrees North latitude, all the way to 55 degrees South latitude. Taurus, Pisces and Leo can be seen from 90 degrees North all the way to 65 degrees South. Aquarius and Libra can be seen from 65 degrees North to 90 degrees South! The constellation Virgo is visible from 80 degrees North down to 80 degrees South, and Orion can be seen from 85 degrees North all the way to 75 degrees South latitude! An observer on a ball-Earth, regardless of any tilt or inclination, should not logically be able to see this far.
“Another thing is certain, that from within the equator the north pole star, and the constellations Ursa Major, Ursa Minor, and many others, can be seen from every meridian simultaneously; whereas in the south, from the equator, neither the so-called south pole star, nor the remarkable constellation of the Southern Cross, can be seen simultaneously from every meridian, showing that all the constellations of the south – pole star included – sweep over a great southern arc and across the meridian, from their rise in the evening to their setting in the morning. But if the earth is a globe, Sigma Octantis, a south pole star, and the Southern Cross, a southern circumpolar constellation, they would all be visible at the same time from every longitude on the same latitude, as is the case with the northern pole star and the northern circumpolar constellations. Such, however, is not the case.” -Dr. Samuel Rowbotham, “Zetetic Astronomy, Earth Not a Globe!” (286)
