I've never seen such birdwalking in my entire life....
Simple as this gentleman, based on the "FAQ" as well as the common sense of shapes.
Lets say theoretically the world is flat. You cannot circumnavigate a plane (flat surface). Correct? And the 150' Ice Wall (God forbid it stops a plane with its trembling heights), would impede further travel.
However this is not true, this is false. You can go AROUND a sphere. Yes there's a pun in what I just said, deal with it, I'm not here to do any favors for anyone.
DO AT HOME EXERIMENT!
Get a globe, and a peice of paper. Set them side by side. The Globe represents, RE, the paper FE. Slide your finger along the globe. Select any one point and move the globe around sliding your finger around it until you come back to the point you've selected (circumnavigation). Do the same thing on a sheet of paper. Once your finger has slid of the piece of paper your journey ends.
So when you guys decide to finally man up and go on that expedition to the End of the World. You give me a call. Until then accept the world is round and please do not procreate.
