>>12202211There is a saying, OP: "You can't fix stupid".
Anyone who actually believes that the Earth is flat and won't budge is just plain stupid, and nothing will fix that. You could put them in a capsule and fly them up to the ISS, and they'd claim it was all an elaborate hoax, it was all on a Hollywood sound stage somewhere, the view out the window was just CGI special effects, and they'd come up with some sort of reason why there appeared to be only microgravity ("we're on an airplane and it's powerdiving!"). They'd talk about the ride up and the ride back as some sort of amusement park ride, more fakery. You could FLY THEM TO THE MOON and even walking on the surface they'd claim it was all an elaborate FAKE.
The only way I can think of you could conceivably make them even begin to believe it's all real would be to put them in a spacesuit and shove them out an airlock with a tether but no maneuvering jets of any kind, and let them flail around in zero-G until they got sick, passed out, or begged to be let back inside.
You can't fix stupid. Their brains are too limited, too 2D, to grasp that it's all real. They're mouthbreathers. Throwbacks.
