I believe I have found the craziest people ever. They claim the earth is flat, and have some of the craziest theories based on how this is possible. Here are some of their beliefs and some of their reasoning.

1) Space travel isn't possible.
2) NASA and the five major space traveling countries are a part of a massive conspiracy.
3) Back in 60's and 70's, NASA spent all their money developing advancing computers to photoshop images. Yeah, that's right, NASA developed the modern computer and Photoshop.
4) Gravity is not real. Dark matter accelerates everything up something something something. I'm not exactly sure, it made nearly no sense.
5) The stars are above us, and the sun is level with us. No one knows what is below us, but some suspect it to be some turtles and elephants (wtf?) or rocks.
6) The earth is flat, but cylindrical in shape. The North Pole is the center of the center of the earth, and Antarctica and the Ice Wall are on the edge.
7) The Ice Wall, a 150ft tall wall made of ice, holds water from falling off the earth.
8) They're all on LSD.
9) Satellite signals are actually from the ground.
10) Sun rises and sun sets are merely optical illusions caused by the cold light from the moon and the warm light from the sun.
11) Earth is 100% unique.
12) Antarctica is not really a continent, because of it's geological shape.
13) Shackleton was on pot, he never saw the Ice Wall because we was on drugs (seriously, I think an 1800's explorer would tell people about a giant 150 foot wall he found while exploring. Keep in mind this would be the pre-conspiracy days >_>).
14) Tides are do to a seesaw effect.
15) Global warming is either 1) canceled out by global cooling or 2) doesn't affect the Ice Wall because they are actually mountains covered in snow.
16) Volcanic eruptions still happen because the crust is thick enough to have a molten core.

Number 16 is my favorite. If the earth is flat, how can it have a core?

I'd love to see how they explain earthquakes and how continents move! Here's the site.
