Curved lines can look straight

The Pantheon.

Okay here's a bit more: the Pantheon, when viewed from a distance, looks perfectly straight. The floor, the steps, the columns. However, when viewed up close, the proportions begis to change. The floor takes a bowed up appearance, as do the steps. The columns look bowed around the center. But they are straight! No. They aren't. The Greeks actually built the Pantheon, along with other buildings, like this. A perfectly flat line appears almost bowed down, or sagging, from a distance. To counter this, the Greeks built buildings, at least important ones, with a bowed shape. How is this relevant. Take a flat line. Any old flat line... Oh! The horizon! It.... Oh wait.... From sea level, it looks flat. Now, the only way to get a flat line is to.have a curved shape... Oh but it has to be flat right? Oh... Oh dear... From even a few thousand feet up, as your prospective changes, and you get further from the globe, you begin to see the curve, slight though it may be. The further up you go... It more it curves. Well. This ended poorly. I really thought I had a flat earth proof. All well. At least the hyper accurate gyroscope experiment didnt show a 15 degree drift........ Oh.......

Flat Earther proves the Earth isn't flat, twice! by Fight the Flat Earth

I agree with you SirWulfe. Our land is unique. From above we see it with a ball around which satellites fly. But on earth itself we find no rounding. And any experience with the horizon, they say that the earth is flat. It is actually flat ... and a ball. I basically understand how it can be, you need to have spatial thinking.
We have the earth many times more than we see with our eyes and measure with instruments, there are hidden areas. When we look into the distance, the horizon stretches before us like a carpet. I think with all the experiments on the definition of rounding on the earth itself, there is a unfolding of hidden space (remember how a particle behaves when it is observed), and therefore the result of all measurements is we measure the earth, which is much larger than what we see . That's because all the experiments - they are true, they do not show the practical rounding of the earth. And do not be afraid of the fact that the earth seems flat because of its huge size. To fall into those hidden areas to an ordinary man in the street is unrealistic, especially the “sharo-faith”. But remember the Germans and Novaya Swabia - they just moved there ...
I waved my tail ... Who does not understand me - throw your slippers at me

You are very nice Heavenly. Much nicer than most here. However, I'm not afraid of the aize of Earth, or falling off. I was using a bit science, and some sarcasm (which I would have been a bit nicer about it if i jad known yoi were going to answer), to get my point across. The Earth can appear whatever it wants. At the end of the day, it is an oblait spheroid.

Thank you for the kindness though. It was a nice change from the usual drivel I get here.
