Some flat earth theorists believe in a physical dome, some in a type of forcefield, and some in no dome. I personally believe there is no physical dome, but there is a forcefield-type dome (possibly electromagnetic).
There is absolutely no dome. This has been proven by rocketry, which works in space. If you are a "genius" who doesn't go along with the "masses", perhaps you should do the rather simple derivation of the Tsiolkovsky rocket equation and truly understand Newton's laws before spouting this stuff. You should also understand at least the Lorentz force law before invoking electromagnetic woo garbage.
I've seen couple clips how light behaves around sun and distant stars and also a clip of rocket hitting an object around 50 miles up. I have also heard stories of planes crashing in some sort wall. I'm generally confused.
What are your thoughts? Let me hear
You've seen no clips of a rocket hitting an object 50 miles up. I'll repeat that again. You have seen no clips of a rocket hitting an object 50 miles up. Post the video if you want to assert this, but I guarantee you that you have seen no clips of a rocket hitting an object 50 miles up. If you're referring to why they start falling, it's because they've run out of fuel. If you're referring to why they stop spinning, this is literally designed into the rocket so they can get a good camera shot. Of course a lot of FE people like to insult NASA and those work for it without even considering a lot of its bright ideas, like
https://en.wikipedia.org/wiki/Yo-yo_de-spin. It is the de-spin mechanism that stops the rocket from spinning, not a forcefield.
It's so frustrating to deal with people who can't do basic research.
