There is a person called Eric Dubay who claims to offer 200 proofs that the earth is flat. He is wrong in every way. 

He doesn’t really offer 200 proofs, because he repeats himself again and again.

They aren’t ‘proofs’  because they are consistently wrong, illogical, based on false statements or on misunderstandings. 

And the earth really isn’t flat!

I don't expect you to take my word for that. It's the last thing I'd want. 

Please read these refutations, follow up the evidence links, try the experiments I suggest so that you can see for yourself. 

I’ve tried to make these replies understandable to everybody, with no more technical stuff than is absolutely necessary to make  the point. I’ve also suggested ways that you can test the important questions for yourself.
I’ve written many of these replies myself, but sometimes I’ve drawn on other peoples work online. If you want to explore further, try these sources to get you started:

200 Proofs Earth is not flat
A mix of the basic evidence in science and mathematics, with lots of fact-checking.

200 Reasons why flat-earthers are simply wrong
A blog by a physicist and bit more technical than mine. Good if you want the arguments in more detail and gives some different source links:

Looks harder at some of Dubay’s earlier claims:

Finally, this isn’t a reply to Dubay in particular, but to all Flat Earthism:

Top 10 Ways to know the Earth is not flat


  1. Thank you for your post. This is excellent information. It is amazing and wonderful to visit your site.

  2. I feel sorry you’re in such denial about the FE. A lot, if not most, of your “refutations” are argued purely out of emotion and what you think to be empirical proof; often contradicting yourself and you attack-usations, lol. You’d started with #1: Showing an image from a fisheye lens; then claiming that FE’ers are always using this to prove. Uhh yeah, of course its used as proof. I’d encourage you to do some research on the extensive footage done by amateur weather balloonist, with footage as high as 20+ miles up, all showing a perfectly flat and horizontal horizon 360degrees. And while watching that footage, go ahead and consider Proof #2. The horizon always appears flat and rises with the height of the viewer. That’s exactly what you’re seeing in the footage. To go ahead and disprove curvature, lets look at Viewable Distances. On a Globe Earth, one would only be able to view an object at x-amount of distance away, before curvature removes the object from view, as a result of the dipping away of the horizon. See Amateur Photographers using the zoom from Nikon p900s. I’m not going to get into the math, bc its late, but from the circumference of the earth (~25k miles), you have a radius of 3965. From the Pythagorean Theory, curvature should come into effect at 8in/mile squared. There’s documented footage of viewing objects that are 20+ miles away. Battleships use lasers to target objects much, much father away than “Curvature” should allow. And as Lasers are perfectly straight, how can this be done if the earth curves in the manner we’ve all been told, and are still being told? The answer is simple: It Cannot. And it Does Not. Let’s talk about the “South Pole”. Have you ever done any research into the SP? Are you at all familiar with the Ice Wall “in” Antarctica? I will enlighten you, and I encourage you to research everything I say. There is a huge Ice Wall that encircles/encompasses the entire earth. Travel of any kind is strictly prohibited of the Ice Wall per the Antarctic Treaty, signed by 48 countries, making any sort of civilian exploration impossible. Admiral Byrd explored it, and never was he able to effectively map, or traverse the entire wall. We have no idea what is past the wall, or the true extent of Antarctica, and we never will as a result of the gov. Prohibition. For an idea of what the FE truly looks like, take a look at Gleason’s 1892 Standard Map of the World. The North Pole is the center of the Earth, it is true North, and the further you travel away from the NP, the farther South you travel, until you reach the Ice Wall, or Antarctica, which then circle the entire earth. Open your eyes.
