Ex-England cricketer and Ashes star Freddie Flintoff has offered his support to a small - but determined - group of conspiracists who believe that the Earth is flat.
'Flat Earthers', as they're called, genuinely believe that the Earth isn't spherical, as science has proven, but is indeed flat. They actually think that.
They think that satellite photos showing the globe as round have been fabricated by those pushing a 'round Earth conspiracy'.
Many also believe that water doesn't fall off the edge because Antarctica acts as a wall of ice that wraps around the edge of the world. It's fucking fascinating stuff, isn't it?
And now the global community has a high profile, if not slightly surprising, addition, in the formed of Freddie Flintoff, who became convinced about the theory after listening to a podcast called The Flat Earthers.
"If you're in a helicopter and you hover, why does the Earth not come to you if it's round?" he said to the Sun.
"If we're hurtling through space, why would water stay still? Why is it not wobbling? Also if you fire a laser about 16 miles, if the world was curved, you shouldn't be able to see it but you can."
But Freddie doesn't believe the Earth is entirely flat - because that would just be silly. Nope, instead he believes it is shaped like a turnip. A TURNIP.
"The middle is the North Pole, around the outside is the South Pole which is like a big wall of ice. This is why all governments now have bases on the South Pole."
The baffling theory is, of course, not a new one. Even as far back as the early Egyptians and Mesopotamians, people were sure that they were inhabiting a flat world.
You'd have thought such a ridiculous theory had been well and truly stamped out by, y'know, science, but somehow Freddie's far from alone in this one.
One Flat Earther, 'Mad' Mike Hughes, has plans to fly 500mph in a homemade rocket - all to prove that science is wrong.

The 61-year-old limousine driver and self-taught 'rocket scientist' has spent the past few years building a steam-powered rocket in his garage, and soon plans to climb aboard and shoot off into the air to prove that the Earth is indeed flat.
Yep, looking forward to seeing how that one turns out.
