Well, I'm glad I made you happy, although I don't think my being right has anything to do with self-righteousness, impatience or stupidity - at least on my account. You are actually under obligation to provide proof of the ball-Earth theory, if you are here to defend it. If you chose not to, I wouldn't blame you. Ball-Earth is quite a childish theory to be defending.
Nope. Flat-Earth is an observation. One doesn't need to prove an observation. One only needs to open one's eyes to... observe it! ;-)
Not so. Other theories (such as Flat Earth), explain the sun or moon rising and setting, the same way as parallel railway tracks appear to converge in the distance. Not proof of ball-Earth at all.
He might not, but I certainly do!
And your logical fallacy is known as the bandwagon fallacy. Just because many people have been fooled by the same lie does not it a truth make.
It may surprise you to learn, but you actually do observe a flat Earth. As this is something that clearly can be observed, I don't think we can argue any further on this point. It would be akin to you arguing that the sky is green and grass is blue. You may truly believe it, but I have no desire to try to convince someone so thoroughly propagandised.
So riddle me this. Why doesn't an object's weight change between midnight (sun underneath) and mid-day (sun overhead), if the equation is true? Say, with a scale capable of measuring a heavier object to the gram. Simple answer is because the equation is false.
And if the universal gravitation equation describes the tidal forces on the seas, explain how the seas still remain in place and are not sucked into the sky. I'm happy for you to introduce your "elasticity of liquid water" component. Indeed, I demand it, as without it, the equation doesn't explain why water remains on one side of the alleged globe at all.
