Antarctica is the ice wall that is the physical barrier to the ends of the earth (as far as we can suppose). The ice wall surrounds the entire planet whose climate is much more harsh than the North Pole. Captain Cook became the first modern explorer known to have breached the Antarctic Circle and reached the ice barrier. During three voyages, lasting three years and eight days, Captain Cook and crew sailed a total of 60,000 miles along the Antarctic coastline never once finding an inlet or path through or beyond the massive glacial wall. This is a distance long enough to circumnavigate the globe several times!
The midnight sun does not exist in Antarctica. Heliocentrists also cannot explain why the Midnight Sun phenomenon is not experienced anywhere in the Southern hemisphere at any time of year. Quite to the contrary, it has been recorded by the Royal Belgian Geographical Society in “Expedition Antarctique Belge,” that during the most severe part of the Antarctic winter, from 71 degrees South latitude onwards, the sun sets on May 17th and is not seen above the horizon again until July 21st! This is completely at odds with the ball-Earth theory, but easily explained by the flat-Earth model. The Midnight Sun is seen from high altitudes in extreme Northern latitudes during Arctic summer because the Sun, at its inner-most cycle, is circling tightly enough around the polar center that it remains visible above the horizon for someone at such a vantage point. Likewise, in extreme Southern latitudes during Arctic summer, the Sun completely disappears from view for over 2 months because there at the Northern Tropic, at the inner-most arc of its boomerang journey, the Sun is circling the Northern center too tightly to be seen from the Southern circumference.
World governments are well aware that Antarctica is something very different than what we are told. Look at the room the members of the Antarctica Treaty System meet in (:
