That's just given me a thought - correct me if I'm wrong, but my understanding is they don't believe in gravity, and the reason we all stay on the Earth is because it is accelerating upwards at a constant rate. So how is it possible to launch a rocket or satellite? As soon as they stop accelerating will the Earth not smash in to them? Or do satellites (and therefore telecommunications, phone calls, TV signals, and the internet) not exist?
There are actually competing groups of morons who have different ideas as to how this all is supposed to work. Some say it's constant acceleration. Some say it's air pressure that's pushing us down. But no, satellites don't exist in any interpretation that I know of. NASA is a hoax.
BTW most of the internet doesn't need satellites even on round Earth. It's mostly cables and fiber. Satellite latency sucks. Not sure about phone calls. TV, GPS, weather, imaging for sure but flat-earthers claim that images from space are fake and the rest of it is done via tall towers and stuff like that.
However they still can't tell me what's the distance from Chile to Australia on flat Earth.
No, I'm not spending too much time in flat-earther threads, but thanks for caring
