It's a ridiculous question?
You believe the earth is a flat disc, with spotlights hovering above it radiating hot and cold light, and me asking what colour the sky is in space is a ridiculous question?
I was under the impression that outside of the ice wall was space, but does the earth, and therefore "atmosphere" continue on?
I looked at the FAQ's, but after:
Q: "Why do you guys believe the Earth is flat?"
A: Well, it looks that way up close.
I just couldn't take it seriously.
