You said a lot so I'll just pick a few if that's cool.
Scientists haven't stopped looking for a better answer, they are constantly refining towards the better answer. There are loads of ongoing experiments.
You say "if this same force was applied to me, I would be flattened..." But the same force is being applied to you, except you have muscles and far less mass. You could ask the same question about the FE theory statement that says we are travelling "upwards" at 9.8 m/s2. Why aren't you flattened?
"We have seen that without gravity, objects simply float around." There is really no such thing as "without gravity." Everything is affected by the mass of everything else relative to each body's mass and distance from the next. What you see on the ISS are objects "falling" inside a vessel, travelling at about 18,000 mph, in effect, also "falling," towards earth in a spiral shape. You can partially feel this in an elevator if you jump as the elevator begins to descend, or you will feel heavy when it stops for the opposite effect.
What I am saying is that after a century of refining a theory and still not being able to perfect it, the science community should be willing to accept proposals of new theories. But they don't, because science has become politics. I was just reading something a moment ago on how climate change has finally been exposed as a hoax, or at least a major scientific institution where many other institutions get their data, has been busted manipulating data to support climate change. This is exactly what I mean. Over the past decade so many scientists have spoken out about their disbelief in clime change, and none of those fuckers have a job anymore. Science isn't science anymore. It is politics and what they want us to believe has nothing to do with what what the truth is.
You are still not understanding me based on this sentence, and I do not know how better to explain it without drawing a picture, so best we just forget this issue.
My experience with looking into the flat Earth theory has revealed that this fact you speak of is something that the Flat Earth Society put forth. The Flat Earth community recognise The Flat Earth Society as controlled opposition, meaning that they intentionally say stupid, unbelievable shit in order to discredit the theory. No genuine flat Earther that I have ever spoken to adheres to this theory. They have all maintained that the Earth is 100% stationary, and that the stars move around the Earth in the firmament, as stated in the Torah or Bible.
You're not even willing to accept a possibility that gravity might not be true are you... I'm willing to accept that gravity could definitely be a thing. I'm just not certain of it. But, if you can only speak from a perspective of certainty, then I'm not sure it is possible for us to have a very productive conversation on this matter.
