  1.  @pizzafrenzyman  "the moon is flat. this is why our view of the moon never changes" When an observer on Newfoundland sees the Moon in his southern sky and an observer on the equator sees the Moon above him and an observer on Tierra del Fuego sees the Moon in the North the flat earther explanation is parallax, that the moon is a short distance above the equator, closer to the equator than the equator is to Newfoundland or Tierrra del Fuego. This does not work, no matter what shape you imagine the Moon is. If the Moon is flat, and appears as a circular disk from the equator, then it will look like a flattened elipse from Newfoundland or Tierra del Fuego. If it is a sphere then the northern and southern observers would see different faces of it because they are viewing it from almost the opposite direction from one another. Also, because of the widely differing distances, they would all see it at a different apparent size, which is not what we DO see. In fact observers from all 3 places see the SAME FACE of the Moon, in the same shape and the same size. This is ONLY explicable on the assumption that the Moon is distant, and the Earth curved. There is no possible flat earth explanation for this. The ancient Greeks knew that the Earth was round, and had used parallax and surveying methods to accurately calculate the distance between the Earth and the Moon. In a lunar eclipse, the shadow of the Earth backlit by the Sun moves across the Moon. When viewing an eclipse, regardless of where in your sky you see the Moon, the shadow of the Earth that crosses the Moon is circular. What shape casts a circular shadow, in any direction? Only a sphere.   The flat earther "map" Shows a north pole, and south diverges in every direction from it. This does not explain why the north pole star, Polaris, and the northern constellations fall below the horizon as one passes into the southern hemisphere, and new constellations come into view. One of these is the "Southern Cross", four stars in such a place that if you mentally "draw" a cross between the opposite stars the intersection of the lines is due south. This serves the southern hemisphere as a south "pole star" in the same way as Polaris serves the northern hemisphere as the north pole star. This is not possible on the flat earth map. The southern cross has to be south of South America and south of Australia. But on the flat earth map south of South America is nearly the opposite direction from south of Australia. On the global assumption, all these observations make sense if the Southern Cross is above the South Pole. On flat earth assumptions, where is the southern cross? A "globe hoax" would require a simultaneous unbroken conspiracy of all the cartographers, pilots, astronauts, astronomers, navigators, surveyors, sailors, physicists, cosmologists, historians and many more that have ever lived since hundreds of years BC. Any conspiracy theory that asserts that ALL THE EYEWITNESSES ARE LYING is BUNK! Scott Fischer "Cable Yaj this [GPS] is done by phone masts not satellite. " There are no phone masts in the ocean.
