The Hollow Earth: Fact or Fiction?

    Admiral Richard E. Byrd of the United States Navy flew to the North Pole in 1926 and over the South Pole in 1929. he referred to Antarctica as "The Land of Everlasting Mystery". In reference to the North Pole he wrote: "I'd like to see that land beyond the North Pole, it is the Center of the Great Unknown."

    In his diary, Byrd allegedly tells of entering the hollow interior of the earth, along with others and traveling 17 miles over mountains, lakes, rivers, green vegetation, and animal life. He tells of seeing tremendous animals resembling the mammoths of antiquity moving through the brush. He eventually found cities and a thriving civilization. The external temperature was 74 degrees F.

    His airplane was greeted by flying machines of a type he had never seen before. They escorted him to a safe landing area where he was graciously greeted by emissaries from Agartha. After resting, he and his crew, were taken to meet the king and queen of Agartha. They told him that he had been allowed to enter Agartha because of his high moral and ethical character. They went on to say that they worried about the safety of planet due to he bombs and other testing done above the surface by governments. After the visit Byrd and his crew were guided back to the surface of the planet.

    Byrd stated that the North and South Poles are only two of many openings into the center of the Earth. He also wrote about seeing a sun below the Earth.
    BUT....

    According to the theory, the Earth’s surface has two sides. The outside ( where we live ), and the inner side ( home of 12 tribes from which 6 use to live on the outer side and even a few alien species are mentioned. They say the Earth in between is 800 km thick.

    Massive objects tend to clump together gravitationally, creating non-hollow spherical objects we call stars and planets. The solid sphere is the best way in which to minimize the gravitational potential energy of a physical object; having hollowness is therefore unfavorable in the energetic sense. In addition, ordinary matter is not strong enough to support a hollow shape of planetary size against the force of gravity.

    Someone on the inside of a hollow Earth would not experience an outward pull and could not stand on the inner surface; rather, the theory of gravity implies that a person on the inside would be nearly weightless. This was first shown by Newton, whose shell theorem mathematically predicts a gravitational force (from the shell) of zero everywhere inside a spherically symmetric hollow shell of matter, regardless of the shell's thickness.

    A tiny gravitational force would arise from the fact that the Earth does not have a perfectly symmetrical spherical shape, as well as forces from other bodies such as the Moon. The centrifugal force from the Earth's rotation would pull a person (on the inner surface) outwards if the person was traveling at the same velocity as the Earth's interior and was in contact with the ground on the interior, but even at the equator this is only 1/300 of ordinary Earth gravity.

    The mass of the planet also indicates that the hollow Earth hypothesis is unfeasible. Should the Earth be largely hollow, its mass would be much lower and thus its gravity on the outer surface would be much lower than it currently is.


    But because our understanding of gravity could be wrong and I'm not sure I'm ready to call Admiral Byrd a liar.

    Tell me what you think!!!!

    The Earth is largely solid. We can image it using p- and s-waves which are produced by earthquakes. The outer core is liquid, but the rest is solid. S-waves cannot travel though fluids, p-waves travel through solid and liquids. There are also transformations in phase in these waves due to transition phases within the Earth. The wikipedia page is quite good here: http://en.wikipedia.org/wiki/Structure_of_the_Earth

    The "hollow earth" "theory" rings, well, hollow.

    It means there are some people that believe the earth isn't solid.

    That perhaps another "world" exists within ours..And may be home to other "beings". Weird stuff. :bugeye:

    It's irrelevant what I think. It's simply bull-shit.

    .

    ah, yes there is a hollow sections in earth floors, just under the crust that contain continents and oceans. creatures in it? who knows, but, not very lickely, it is extremly hot their, and alot of pressure, and, idk, uit's, molten rocks and stuff, not if it is even water, but, who knows? maybe there are some microsopic life. but another complete world, no very likely

    I'd think that from what science already has found out about the inner Earth we can say for certain today that it isn't a hollow , empty place but filled with much matter both liquid and solid. So while Byrd might have had some wild ideas back in his day, we know now that he was wrong.

    Huh??? Just because we haven't figured out how gravity elegantly integrates with the other three fundamental forces (electromagnetism and the strong and weak nuclear forces), doesn't mean that there's anything major wrong with what we have figured out.
    Well then call him a good storyteller, but we've learned too much for that story to be entertaining any more. Sort of like the Bible. Old stories can be highly entertaining, but eventually you learn enough that they require too much suspension of disbelief to be enjoyable any more. Much less believable!
    I think you should consider how much the tectonic plates that comprise the earth's surface weigh. And then figure out just how large a cavity could exist beneath them, leaving huge portions of them unsupported. Look at what the force of tectonic movement can do: raise mountain ranges several miles high and excavate oceans several miles deep. Do you really think those things can be suspended above a volume of air large enough for there to be an undiscovered ecosphere down there?

    In the billions of years since this planet cooled and (mostly) solidified, the tectonic plates would have cracked under their own weight and filled in the void.

    Sure, there are caves, and perhaps they go very deep. But that's quite different from this tall tale. An empty space big enough to fly multiple airplanes? Calculate the force on the ceiling of that cave and then you tell me how you would design it to remain stable.

    I think you should call Admiral Byrd a liar.

    Alternatively do some research which may reveal that some of what is attributed to him is fraudulent as well as fictional and farcical.

    I do not believe our understanding of gravity is wrong. Byrds witness account is one observation vs. 150yrs + of research and discovery which has created heaps of facts that all point to basic model of the Earth that they teach you in geology 101.

    If there was any sort of huge hollow area under the earths crust, don't you think it would have collapsed?

    If we can assume other unusual objects to be solid (that is, occupied with matter throughout), such as the Sun, asteroids, and certain lab equipment, then we can conclude that the earth is solid as well by virtue of its gravitational effects with ordinary objects which we know are non-hollow.

    Earth is more fluid than solid.

    No, only the outer core is liquid, therefore the Earth is mostly solid (by any measure).

    I sit on the idea that the lava is not solid and has a high viscosity.

    It's irrelevant anyway, in the context of this discussion 'solid' means solid shape (as opposed to a hollow shape), not solid as in the state of matter.

    It's in Guatamala and the only thing at the bottom is liquid lava Trolls.

    Stupid question: What keeps the inner core solid?

    Pressure. There is an interesting article in this week's New Scientist that discusses the recent consideration that the super Earth exoplanets may not be suitable for life. There size makes it likely their cores are solid because of the pressure, so that no magnetic field is possible, so that there will be no protection from cosmic rays, and atmospheric erosion by the stellar wind will be severe.

    an artificial Ionosphere can be created radiologically so there a magnetic field isn't a necessity.
