A few year back, there was a Netflix documentary about flat earther. They’ve done a couple of experiment to prove that the earth is flat which (Spoiler alert) demonstrated that the earth is round.
So now that these persons have demonstrated scientifically that the earth is round. How are they doing ? Still flat-earther ? or did they give up with the amount of evidence they collected ?
The documentary was called “Behind the Curve” and featured Bob Knodel. Unfortunately he passed away this year. https://www.robertsfhsc.com/obituary/RobertBob-Knodel
It looks like you still believed in the theory though. He had a YouTube channel that was devoted to flat Earth conspiracy.
