I am a professor of physics. Our team recently discovered this whole Flat Earth 'thing' and we took our time to study it further.
As it might not be of much surprise, the claims are completely bogus.
However, we found a fascinating way to use them in classes.
We used many of the claims here from the board and other sources, put them in a document, corrected grammar mistakes and such, and told the students that the document is from a preprint server and they are supposed to go through the material and tell us if there is anything we might have missed.
They had no bias, since they do not know it is from a bogus conspiracy item.
We also told them that, if they find any errors, they are required to correct them in detail.
Since all claims are completely nonsensical from a physics point of view, it requires a lot of effort to 'correct' them in writing (because of the level of absurdity involved).
It is a great experience for everyone involved (and no one gets a bad mark, because the course is not mandatory).
When we talked about our project during a meeting, the psychiatry department got all ears.
They become invested in further exploring the topic of conspiracy 'theories'.
They created a new project, where they analysed the posts made by some of the individuals here on the board who have a LOT of posts already made (without naming names). Our psychiatrists, to make a long story short, recommended that those people seek psychological help.
According to our psychiatrists, who went through thousands of posts here on the board, mental illness is a leading factor in this entire 'Flath Earth' issue.
By the way ... two users were recently banned from the board, because it was suspected they were the same person.
Both were associates of us.
Apparently, in the Flat Earth world, no one has ever heard of shared workspace, which usually means a shared IP address, sometimes by dozens or hundreds of people.
It seems symptomatic for Flat Earth followers, to only see what is exactly in front of them - without any knowledge or understand of anything else it might mean.
Which is ironic, because all evidence that is in front of them, is denied by them.
Fascinating.
Thank you.
It was really entertaining, from an academic point of view.
