I was putting up some wall decorations earlier today and was painstakingly realigning everything until it looked level to my eyes. It might be just a hair off, but if I don’t correct it, I’ll see the misalignment almost instantly and get bothered for the rest of time until I fix it. Has anyone investigated, or is there literature on the minimum perceptible angle from level to the naked eye?
The Earth is curved.
Oh, you’re one of those round-Earth nutjobs?
Ha! No, what whackjobs those people are. No, clearly the Earth is donut-shaped. This is obvious, because the Bible says so. The lizard people are suppressing the information, except on the internet. And talk radio. And tabloids.
Donut shaped!
