First I was going to pick, "Drill Through The Planet" because it made me laugh out loud, but the more practical action for them that is also being taken by creationists would be to, "Lobby To Have Their Theories Taught As An Alternative To Conventional Science In Kansas".
I am still not convinced that they take themselves seriously.
At least some do. I have 3 in my office of 18 (Georgia, need I say more?). Only 1 of them is slightly "on the fence". They are also devote Christians and Anti-vaxers.
Tho I voted for "Lobby..." I did so both as jest & thinking,"Well, if the ID'ers can do it...". Guess I'm not surprised it has the most votes, followed closely by "Run for Office..."!
Even medieval people were not that dumb. It was the author Washington Irving that started the myth that people used to think the earth was flat. Any visit to the sea shore or boat trip on a calm day shows the truth. I do wonder just how many actually believe this gunk and how many just find it a great excuse to troll?
The problem with the internet and social media is that it gives a tiny, insignificant but vocal minority an opportunity to find more like minded idiots and to sound more important than they really are. They really are morons and should be ignored. I doubt that it is possible to convince them of the truth because they are surrounded by it all the time and they choose to ignore it.
...and a hell of a lot of people are very stupid and very gullible!
none of these answers. they will rely on ignorance
They will find a spot to hang upside down from the edge and see the elephants that are holding up the disk world. There are books written about that. They should all read them and give up on bending physics for the real world towards their crazy notions!
Push them off the edge if they won't jump!
First we need to get them all there!
A few years ago, VSauce, one of my favourite science YouTuber talked about the Flat Earth theory (and its history).
Early in the video, he presents what it would be like to live on a flat Earth - considering that gravity is real on a flat Earth. Basically, if gravity exists on a flat Earth, gravity would pull everything towards its centre - rather than "downwards". Therefore, everything further from the centre of this "disc" will have to be built in angle away from the centre. Otherwise, it will simply topple towards the centre.
VSauce then traced the origin of the recent incarnation of the flat Earth beliefs to, guess what, a religious sect which branched from Christianity/Catholicism in Zion, llinois in 1906. Voliva, that church's leader, enforced the flat Earth ideas in schools and in public places (via signage, etc.)
However, VSauce does conclude that for some, Earth would look flat. But those will have to be travelling at 99.99...% the speed of light.
I saw this a while ago, too. Now there are a bunch of debunkers & YT'ers reacting to FE videos out there. Yet they won't go away!
@phxbillcee Yeah, it amazes me that, with all the information available at our fingertips - literally, people are still taken in by snake oil salesmen. It is unfortunate that the Internet, facilitated by algorithms, has allowed us to form into factions (based on our own information bubbles).
@SamKerry Of course, if you let it, which I make sure to when I have the time, I'll just let YT take me where it will. Just grab some of the "suggestions" to the right at random, & the more you do that the further you get from the original subject or viewpoint. Now, sometimes it's places you may not want to go, but if nothing else, it helps show you what's actually out there.
