I think flat earth ideas are fascinating. Guess I'm a bit nuts but I enjoy reading how they explain things. :)
I don't think they are more dumb than anyone else. If you ask someone random to explain how gravity keeps the water on the surface, they can't of course. Everyone goes to a web page and looks it up.
So I enjoy reading it. It's just fun and interesting.
If the Earth is flat, what makes flat earth believers think you'd fall off the edge and not simply step onto the other side of the coin? If you fell off where would you go? Cuz they don't think space is real, either.
You’ve actually never walked a step in your entire life. Only, the memory of having just completed the final step of walking to your current position is injected into your mind and continuously updated. This avoids the need for an infinitely large flat surface.
When you move, you actually stay in the same coords (0,0,0) and the world is moved around, avoid bugs with lost precision at large values. Twinkling stars? Glitches in the rendering of far away objects
