Thanks for sharing that. What's a crack up is that these guys just love this flat earther named Rowbotham that was promoting flat earth in the late 1800's. He was sighting ships at 6 miles distance on the Bedford Canal in England, and one of his followers put up a bet that no one could prove the earth was round.

So a surveyor stepped up with his theodolite and won the bet from Rowbotham by showing the curvature.

But flat earthers today ignore that Rowbotham lost because someone who understood science did the experiment correctly to avoid refraction and measure the curvature.

Yet they still LOVE Rowbotham and ignore the fact that surveyors were measuring the curvature of the earth since long before Rowbotham lost his bet.

Just ridiculous.
