The billionaire CEO of the Columbia Sportswear Company has just made anyone who believes the Earth is flat an opportunity of a lifetime. 

Tim Boyle, 76, announced a new competition on Tuesday, which challenged 'flat Earthers' to find the actual edge of the planet and bring back a picture of the abyss that sits beyond.

Boyle, who is worth an estimated $1.6billion, said the reward for their world-changing discovery would be the control of his $3billion family business, which was founded in 1938.

The announcement was part of Columbia's new marketing campaign called 'Expedition Impossible,' featuring Boyle walking around the company's Oregon headquarters, promising that everything from the meeting rooms to the coffee machines would be property of the winner.

'This message is for flat Earthers. You guys claim there's an end to the Earth. Well, just go snap a picture, send it to us, and you get the assets of the company. All of it. No paperwork, no lawyers, no catches,' Boyle declared.

Humans have known that the Earth is round for over 2,000 years, and scientists continue to collect mountains of evidence to support this conclusion.

This includes simple proof, such as ships disappearing as they sail over the horizon and the round shadow Earth casts on the moon during a lunar eclipse, to more concrete evidence like photographs taken by shuttles and satellites in space.

Despite having visual proof, many who subscribe to the flat Earth conspiracy theory believe this evidence is illegitimate or fake.

The modern Flat Earth movement started in 19th-century England with Samuel Rowbotham, who published 'Zetetic Astronomy' in 1849 under the pseudonym 'Parallax,' claiming Earth is a flat disc and forming the Zetetic Society.

His ideas, based on pseudoscience like the Bedford Level experiment, spread to the US and were revived by groups like the Universal Zetetic Society after his death. 

Today, many flat-Earthers fundamentally distrust scientific institutions like NASA and government bodies, viewing scientific evidence as part of an elaborate, ongoing conspiracy designed to hide the 'truth.'

Boyle is a member of the sportswear brand's founding family, which started as the Columbia Hat Company after his grandparents emigrated from Germany.

While the CEO vowed there wouldn't be any paperwork if someone could produce proof the Earth is flat, a man claiming to be Boyle's lawyer quickly appeared in the ad to reveal the fine print in Columbia's offer.

It turns out Columbia has actually created 'The Company, LLC,' which the clothing giant noted still had assets valued at $100,000, meaning one lucky flat Earther could still collect a nice payday if they succeed.

However, Columbia has also made sure that flat Earthers can't get creative and take a shortcut to their massive prize.

To clarify what the 'edge of the Earth' would actually be, Columbia posted that they're looking for a photo with 'a visible, physical end to the planet Earth.'

That could include anything from an infinite sheer drop, an abyssal-like void, or clouds that stretch into infinity.

However, the clothing company noted they will not accept a normal cliff-top, cul-de-sac, or 'your buddy Dave legally changing his name to 'The Edge.'' 

'Hey, flat Earthers, do me a favor. If you're going to the edge of the Earth, wear Colombia. You'll need it. Best of luck,' the billionaire chairman added.

According to Dr Ian Whittaker, a lecturer in physics at Nottingham Trent University, the reason why we see a straight horizon is that we are on the ground rather than in space.

At ground level, humans can only see a few miles from one side of the horizon to the other, which is not enough to see the curvature of the Earth.

'As an analogy, you look at a basketball and see the full curvature because you are massive compared to it,' Dr Whittaker told the Daily Mail.

'Now imagine a microbe on the surface, what would it see? It would just be a vast expanse of flat area because its height compared to the curvature of the ball is tiny.'

In April, civilian astronauts captured brand new footage of Earth from space that clearly showed the planet's curvature, sparking more outrage among the flat Earther movement.

The video was taken by the passengers of the Fram2 mission, a SpaceX flight that put humans in orbit over Earth's poles for the first time ever.

'Flat Earthers in shambles,' one X user posted in reference to the video.

However, the mocking enraged some flat Earth supporters, with one person posting: 'In shambles my a**!! Complete the circle, are we in another ice age lmao, why is half the Earth covered in ice? Stop using curved lenses!!'
