99% flat surface with domed firmament
I've tried to take the "devil's advocate" side and demonstrate to myself that the earth is a globe. I do this all the time with various issues. I perform a thought experiment where I believe that the earth is a globe and I'm debating a flat earther. What's my proof/evidence? NASA photos. So much fakery with NASA that it can't be used. Eratosthenes' sticks? Depends on how far away the sun is. Radio waves moving around the earth? We have no idea what they could be bouncing off of. Firmament? Something else? After all, they claim that radio waves can bounce off the ionosphere. I urge you to do the same thing, DL. If you believed earth is a globe, what would your evidence be. It would be cool to have a thread where people leaning flat earth would present their best evidence in favor of globe earth.
I can't buy the explanation for the "see too far" phenomenon as "refraction", especially in light of the two-way experiments that have been performed, the clarify of objects seen too far, etc. Results are simply too consistent and too clear for me to be able to convincingly apply the deus ex machina explanation of refraction. Besides, refraction is not a proof of globe earth, just a counter to flat earth that's convenient. But has anyone done the math to positively prove that refraction is taking place? Never. They just pull it out like a rabbit from a hat, and they simply pull out a word or a concept.
Someone ran the numbers on the world's faster jet, that it would have to nose-down an astonishing amount every second of flight, like nearly 1,000 feet (can't recall the exact numbers), but it would have to be at a perfectly constant rate to avoid fluctuations in altitude up or down.
I leave the 1% there because it's theoretically possible that all the experiments performed have ben faked, but I find it highly unlikely, or because another theoretically-possible explanation is that we live on a globe that's MUCH larger in circuмference/diameter than science claims.
And the notion that a pressurized atmosphere can exist without a container and adjacent to a nearly perfect vacuum I find utterly absurd. Gravity cannot explain the phenomenon.
There are simply too many problems with globe earth that I can offer no convincing explanation for.
Stationary earth, 100%.
