Show this selfie from the top of Everest to a flat Earth conspiracy theorist. Immediately

In a Reddit post, captioned “Checkmate flat Earth society”, user amazed_spirit shared an image of a person posing for a selfie at the summit of Mount Everest, the highest mountain in the world. To Flat Earthers’ dismay, the image clearly shows the curved edge of the planet in the backdrop.

Reddit users stated that this evidence finally debunks the flat Earth theory, with one saying:

Forget about curvature arguments. The fact that you can only see 2.5 per cent at a time proves it isn’t flat. If it was flat you should be able to see the whole thing from even just the top of the tallest mountain or on any commercial flat.

Though it is unclear whether the photographer was using a fisheye lens, which could have distorted the image.

As of yet, there has been no comment from the most prominent voices in the flat Earth movement, but it is doubtful that the image will have swayed their belief the earth is not round.
