Artemis II conspiracy theorists
I've been watching the live Artemis II feed off and on for hours today, and predictably the comments are littered with flerf conspiracy junk.
I realize that there is a certain psychology that fuels these people, and simply pointing out verifiable facts (e.g., various tests/experiments that can be conducted here on Earth) rarely gets them to stop spreading misinformation. That said, I'm curious whether any (semi-)professional astrophysicists here have any arguments to debunk flerfs by pointing out physical properties of Earth that require a sphere/ovoid?
I know that's an awkwardly worded question because I'm not sure how to ask about what I don't know 😊. I'm just wondering if there's something I as a layperson with an interest in astrophysics could use to combat flerf conspiracies in a way that they can't explain away with one of their faux explanations (e.g., the "law of perspective" to explain ships appearing lower over the horizon)?
