The flat-Earthers often clog my notification feed on Twitter, occasionally endorsed by a minor celebrity hoping for some headlines and accusing us of not taking their evidence that the Earth is flat seriously enough.
If they do wish to be taken seriously, maybe flat-Earthers should stop suggesting such stupid proofs as evidence for their baseless arguments.
Here’s a short collection of some of the inane ideas that flat-Earthers have tried to use to prove the Earth is flat.
Look Around You
The Flat Earth Society claims that "The evidence for a flat Earth is derived from many different facets of science and philosophy. The simplest is by relying on one's own senses to discern the true nature of the world around us... This is using what's called an empirical approach, or an approach that relies on information from your senses."
Sounds like a very reasonable approach. Too bad they've missed the gigantic deal that our senses are rather unreliable and humans are intrinsically biased. Science has been battling with this since its creation, you cannot use the empirical method without realizing its limitations.
If you accept the empirical method, then get off the Internet. If you only believe what you can see or hear or touch, how can you be using Wi-Fi that relies on invisible (to humans) radio waves? And what about germ theory? Or magnetic fields?
Oh, the flat-Earthers are still here? It appears that they only care about sensory evidence when it suits their goals. If we were actually on a flat Earth, things would look very different.
But I Can't See Any Curvature
Disproving flat-Earthers' ideas just requires us to demonstrate the limitations of our own senses, and, perhaps, the limitations of their intellects. The “if you look around you can see that the Earth is flat” argument falls into the latter category.
The Earth appears flat because we are tiny and it is huge. But if you want to see for yourself that Earth isn't flat, just climb a hill, head to the top of a skyscraper, or go on a hot air balloon ride. Actually, the latter would be the most effective. You will literally see the horizon expand.
