@absurdlyobfuscated @demonofustio @AsukaNeko @catmanmancat @MadrePappagallo @p @matty @Terry Yeah it doesn't make sense to me that people use one area and expect that water will always stay flat. We know on small scale that doesn't happen (miniscus), so why wouldn't it happen in some other way on a larger scale? Average curve "drop" is 7.85 meters per 10 kilometers, so that's a hard thing to notice but would be noticeable. People bring up water self-leveling, but in reference to what? That type of curve is functionally zero at human scale (things we can easily build by hand or move by hand), and there's basically no way to "see" flat vs curve at the same scale. Even with advanced optics, how are you supposed to understand what you're looking at or prove that your measurements are objectively straight etc. Math suggests round.
