Flat earth 1
Most people over the age of five know that the Earth isn't flat. But for some reason the flat Earth conspiracy just won't go away.

Although there is already an overwhelming body of evidence which suggests that the Earth is round, one picture might have just put all the theories to bed once and for all.

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.

Still, a YouGov survey recently revealed that just 66 per cent of 18-24 year olds in the US believe that the Earth is round, so it would seem that this argument is far from settled.
