Inside the weird world of conspiracy theorists convinced the Earth is HOLLOW with ‘alien’ humans and Nazis living inside

IF you thought the ‘flat Earth’ theory was the barmiest conspiracy you’d hear about all year, think again.

Because there’s a growing community of people convinced the Earth is HOLLOW with a race of superior “alien” humans, Vikings and Nazis living in paradise at the centre.

They even believe that flying saucers and UFOs come from within the interior earth – sent from the highly-evolved tribes to spy on us and prevent nuclear war.

Spearheading the bizarre movement is Rodney Cluff, author of World Top Secret: Our Earth IS Hollow.

He was so confident in the theory that he organised a 2007 voyage to the hollow earth – with a plan to set off from Russia on an icebreaker ship to find an “opening” at the North Pole.

The £15,000-per-head expedition was cancelled, but this in no way dampened his enthusiasm for the theory that flies in the face of modern scientific thinking.

He told SunOnline that the movement has exploded in popularity – with thousands subscribing to the idea of an inner sun and earth.

“More and more people are coming to terms with the fact that the Earth is hollow. I get emails from people learning about it every day,” Mr Cluff said.

“It’s definitely growing in popularity – certainly not in the millions but maybe in the thousands.”

So what does Mr Cluff think of the loony rival theory that the earth is flat?

“I don’t know how the flat-Earthers can be so confused,” he told SunOnline.

“They are obviously wrong. The world is not flat – it’s hollow. They reject all the evidence.”

Contrary to flat-Earthers, the hollow Earth movement believes the planet is a sphere – or more specifically, a “doughnut” shape.

And the theory does not just stop at our Earth – the group believes the Moon, Sun, stars and others planets are all hollow bodies.

There is thought to be three “substantial” openings into the inner earth – two near the poles and one in the Himalayas.

Mr Cluff believes the shell of the Earth is about 800 miles thick, from the outside to the inner surface.

“Suspended in the centre of that hollow is an interior sun that is divided by day and night sides,” he says.

Those who claim to have travelled to the inner earth have described the land as like the Garden of Eden.

Norwegian sailor Olaf Jansen claimed he sailed with his dad through an entrance to the Earth’s interior at the North Pole in 1811.

He told author Willis George Emerson how they lived in the beautiful paradise for two years.

“The city of ‘Eden’ is located in what seems to be a beautiful valley, yet, in fact, it is on the loftiest mountain plateau of the Inner Continent,” Jansen said.

He claimed the “super humans” living there were at least 12ft tall and never got ill.

As the hollow Earth theory has grown in popularity, so has the speculation about the people apparently living in the centre.
