There are two hollow earth theories. According to the first one we live on the crust, but there is another world on the inside where lies - some say - the realm of Agartha, the home of the King of the World (see, for example, the fantasies of French philosopher René Guénon). The second theory has it that while we think we live on the outer crust, we actually live in the interior (on a convex surface instead of a concave one).One of the first hollow earth theories was proposed in 1692 by the English astronomer Edmund Halley (discoverer of the now-famous comet), who suggested that the Earth was composed of four spheres, each embedded in the others like so many matryoshka dolls, illuminated by a luminous atmosphere and perhaps inhabitable. The theory was reproposed in the early 19th century by J Cleves Symmes of Ohio, who wrote to various scientific societies: "To all the world: I declare that the Earth is hollow and habitable within; containing a number of solid concentric spheres, one inside the other, and that it is open at the poles 12 or 16 degrees." Symmes believed that at the north and south poles there were two apertures that led to the interior of the globe. He attempted to raise funds for an exploration of the polar regions to locate these entrances. The Philadelphia Academy of Natural Sciences still has a wooden model he used to explain his theories. The idea was later championed by Jeremiah Reynolds, a newspaper editor, who took it upon himself to promote the expedition at the expense of the American government (a request ultimately denied). The journey was unsuccessful, since he and his party were thwarted by Antarctic ice. At the end of the century the theory was revisited by cult leader Cyrus Reed Teed, who said that what we believe is the sky is a gaseous mass that fills the interior of the globe with areas of bright light (sun, moon and stars would not be heavenly bodies but visual effects). It is widely rumoured on the internet that the hollow earth theory was taken seriously by top-ranking Nazis who believed in the occult sciences.

In some circles of the German navy it was purportedly believed that the hollow earth theory would make it easier to pinpoint the exact position of British ships because, if infrared rays were used, the curvature of the Earth would not have obscured observation. Hitler allegedly sent an expedition to the Baltic island of Rügen where a Dr Heinz Fischer trained a telescopic camera toward the sky in order to spot the British fleet sailing on the interior of the convex surface of the hollow earth. It is even said that some V1 missiles went astray because their trajectory was calculated on the basis of a hypothetical concave surface instead of a convex one.

So thats what gravity was all along!

Centrifugal force!

Oh the irony (I think regular posters will know what I'm talkin about)

At this point, I think anything is possible.

i remember max posting a topic about this. i found it very interesting..having a different idea about our earth. but it is very hard to find strong evidence to support this theory. it was like the hollow moon theory also. very hard to prove >.<. although i dont accept this theory because the evidence is so low or maybe non existing...i will give it a little possibility. well have fun discussing this topic people

-rice

If we had a hollow earth wouldn't it implode because of the gravity of the sun combined with Jupiter

ya think it would thats kinda weird

That's exactly what they said in the "Journey to the center of the earth" book

So Cyrus Reed Teed's saying this is a 'visual effect':



Absurd..

Ya, Cyrus was kind of off the mark, but he was an interesting person. I live about five miles from the settlement he built in Estero, Fl. It was donated by his follower to the state. I remember seeing the last of his followers sit in a rocking chair one day while I was on tour of the settlement.

What observations or evidence lead folks to this conclusion? Clearly this has been rebuffed by people with telescopes and a lick of common sense several times already.

Someone believed that? Really?

Why don't we just ask the astronauts what they saw when they left our atmosphere? This idea is BS, there is nothing to prove it true.

After being around so long there is bound to be something inside the Earth that would astound us. Maybe a bomb and where all going to die any second. But thinking it's hollow is silly.

Ever been inside a cave ? I think that may be, what they mean by hollow. I personally love exploring caves, some have underground lakes and they don't know how far down they go

thats impossiable

[attachmentid=27697]The Earth Hollow?............Not A Chance Poopie-Pants!!!!!!!!!!!!!!!!!!

just when you thought you'd heard all the best giggle inducing theories, people that thor woff the most ridiculous statements and are dead serious about it

Well, there are people that think that the earth is flat, that there is an alien base on the moon, that the moonwalks didn't happen, and that the world is run by shape-shifting lizards... So really it isn't all that far out there when you consider the other strange ideas.

The idea that planets are hollow has been around for a long time, but science is only just beginning to consider it worthy of genuine investigation.

This website sets out to prove that the Hollow Earth Theory has credible scientific merit and should not be ignored. There is a wealth of evidence surfacing today that throws our current beliefs regarding the structure of our planet into serious doubt. Our goal is to accumulate as much of this information as possible and provide it in one easy-to-access place for all.

""Was the constant of cosmology the only blunder that Einstein has ever had in his search for gravitomagnetism or is it an iceberg of the biggest blunder on Einstein equation of gravity? Why did astronomers gather circumstantial evidence that massive bodies attract light without taking into account the diffraction of light by matter (the Sun for example)? Is science an ideology, a dogma or a huge business? Are some scientists merchants of science fiction? How does it come that the old guards of relativity have not yet presented a global, coherent and falsifiable gravitomagnetism theory and at the same time continue considering themselves as experts in relativity? Are they the old guards of an immovable past or are they experts in freezing science progress? The old guards are spending huge amounts of tax payers’ money, do they know what they are looking for or are they just speculating on what might be measured? The old guards have not yet developed a falsifiable gravitomagnetism theory, how do we expect them to analyse the data? What went wrong with the mission? Is the data crashed? Should the tax payers ask the old guards to give an account on the money spent in space research? Why are the old guards scared about testing the linear vector gravity with the available data or by simulation? What is behind all this strident silence? Are the old guards of relativity stuck? Time will tell. ""

It has been prooven the earth is not hollow by observations made of the core using sonar etc. We can actually see inside the planet using various frequencies of sound waves and bounce them off the core and other layers that the Earth is consisted of.

The Earth is solid and very dense anyone who beleives otherwise is clearly not the sharpest knife in the drawer. This has been prooven scientifically and the 'hollow earth theories that have popped up over the years are bogus.
