A flat-Earth conspiracy theorist and YouTuber has taken a spirit level onto a plane to “prove” that Earth is flat once and for all. His "experiment" has since gone viral, just not in the way that he'd hoped.
YouTube conspiracy theorist D. Marble took a flight from North Carolina to Seattle in order to “monitor whether or not the pilot would dip the nose of the plane to compensate for curvature”.
He and some of his followers believe his video, below for your entertainment pleasure, proves that Earth is flat.
“I recorded a 23 minute and 45 seconds time-lapse, which by those measurements means the plane traveled a little over 203 miles," he explained in his video. "According to curvature math given to explain the globe model, this should have resulted in the compensation of 5 miles of curvature. As you'll see there was no measurable compensation for curvature."
"Understand that gravity is a still just a theory," he goes on to say. "No more defending what we know to be true! Now we take the fight to the enemy! #FEOffensive.”
Commenters on the video have embraced it as proof that the Earth is flat, and billions of people are involved in a conspiracy to cover it up.
However, over on Twitter, it has been met with a bit more healthy skepticism, and people have taken the time to point out some key flaws in his experiment.
Amazingly, there are countless Facebook pages, YouTube channels, and forums dedicated to claiming the Earth is flat, something that humans disproved back in the times of the Ancient Greeks. It even has some celebrity supporters.
If you believe the world to be flat, here's a helpful reminder of why it's not, or perhaps try booking a flight to wherever it is you think the world ends, and have a look for yourself. Be sure to upload your results to YouTube.
