Hollow Earth May Be the Weirdest Theory of the World

hollow-earth-1.jpg

So wait, what? The Earth … hollow? Yes, it’s an insane theory, and yes it is as fictitious as the fairy tales that gave rise to it, yet at the same time it can’t be directly disproved. Why? Because we have never actually dug more than about 15 miles below the surface of the Earth, so there is no 100% direct evidence the Earth is solid through an through! Does this mean Hollow Earth Theories could hold true? Sure, and Santa might actually drop by 6 billion houses a year on a sled pulled by a glorified pack of deer.

What may be most amazing about Hollow Earth theories is the fact that some people believe them even today. One self-identified scientist and explorer is currently trying to raise two million dollars to mount a mission where no man has ever gone before: through a polar ice cap and into a supposed ‘Inner Earth’ with its own oceans, continents and of course its own sun. What is strangest about his video presentation on the subject (above) is the deadpan, candid and intelligent-sounding way in which he presents his arguments.

Shocking as it may seem that some people still believe the world to be empty at its core this idea is unsurprisingly nothing new. Early theorists held that there were a series of concentric spheres within the Earth while more recent models have posited a viable interior space or even that we occupy the center rather than the interior surface of sphere with everything else in orbits within this sphere.

    You forgot to mention that a central part of the Hollow-Earth doctrine is: “The Earth is hollow and we actually live inside the sphere, not on its outside”. “Hi-five!” (C) Borat

  2. 2Reflection Seismology is wrong?

    We can see inside the Earth in much the same way we can see inside our bodies with ultrasound, just ask any seismologist.

    He states that “it can’t be directly disproven” just because we haven’t seen them. I know that I have bones inside my body and not a hollow core, as the X-Rays and other scans say that they are there. But I’ve never actually seen the bones in my body.

    I’d like to know why he thinks reflection seismology is wrong.

    The hollow earth theories were started by 19th-century crackpots, but the ideas were used to good effect as a supplement to the “Basic” and “Advanced” Dungeons & Dragons games:

    Gamers had fun inventing imaginary Tolkienesque worlds — with a hollow Earth, they’ve got two for one!

    amazingly, a whole bunch of folks also believe in a hollow God! a Hollow religion, and a hollow president. See,?, stranger things do happen…

  5. No no, the Earth is flat and the center of the universe!

    http://theflatearthsociety.org/forum/

    Wait, why are these theories wrong? Can anyone give me a real reason for why I should believe any of this beyond the fact that I am told to believe??

  6. Ahem.

    From the uneducated cretins espousing the “hollow earth theory” one would expect ignorance and hyperbole…

    But in this day and age, and from someone educated and intelligent enough to navigate the internet, one expects better than the outrageous (and wrong) statement: “Because we have never actually dug more than about 15 miles below the surface of the Earth, so there is no 100% direct evidence the Earth is solid through an through!”

    Hello? Seismic waves? Travel THROUGH the earth? Speed of these sound waves directly relatable to DENSITY? Seismic travel times are so througoughly studied and accurate enough they can discern different SOLID, PLASTIC and SEMI-LIQUID layers and the the exact mineralogy of these layers as they travel through them? You never heard any of these ideas? You never, ever took an elementary earth science, planetary science, astronomy, physics or GEOLOGY class? You couldn’t be bothered to look up on the web whether or not direct evidence exists?

    Can you be that uneducated and ignorant?

    There is abundant, and VERY GOOD AND VERY DIRECT EVIDENCE that the earth is not, infact, hollow…

    Unlike, apparently, your head.

    That diagram up the top is seriously flawed. There is no way that the centre of gravity is where it indicates, as it would be in the centre of the sphere regardless of whether there was a sun there or not. The guys hypothesising this crap are ludicrous at best, all out talking from their arse at worst

  8. 8Sage

    thad be badass if they found that.

  9. 9Someguy

    Actually, a center of gravity could actually be where he it says. Everything has a gravitational pull based on mass, you just don’t notice it because the pull from the earth is millions of times greater.

    The sun in the center of earth is what I would have a problem with. There’s no conceavable way a mass of anything could be dense enough to produce fisson (and generate heat and light) in a small enough area that the inside of the earth would be survivable. A star dense enough to produce fission on it’s own would have to be many times the size of earth itself. If indeed an internal start was possible, it would have also burned itself out long ago.

    Inner earth has no gravaty.

    In much the same way a faraday cage has no magnatic waves inside it, a hollow sphere will have no gravaty inside it.

    There for, even if there was an inner earth, it could hold no animals (as they would float away from the “surface”). More over, there can’t be any water or “rivers and seas” (as they too will float away).

  11. 11Any rational human being

    Of all the completely full of crap nutjobs on the exterior of the earth you are their king.

  12. That’s the worst hypothesis ever.

  13. 13Thorn

    Charles Lutwidge Dodgson (Lewis Carrol) once demonstrated with a mathematical model that if the earth were hollow, there would be no gravity on the inside as the gravitational pull of the near side is exactly equal to the gravitational pull from the far side. I think the whole “gravity centers on the crust” Thing is him miss-understanding the implications of what this means.

    This guy is a complete kook, big headed and full of s**t. There is no reason to think that the earth is hollow but there is ample evidence that it is not. This man is clearly not a scientist. Oh. The whole “Unexplained waves” thing is bollocks by the way. Nice mission statement Mr. Ph.D ~snigger~

  14. 14james

    ok lets say this is true were would lava come from?????

  15. 15John Steimenson

    C.H.U.D.S and Hans Moleman live in the center of the earth.

    Morlocks too.

  16. 16A really smart guy

    Actually we are in the center of another palnet that is much bigger. It’s true…. Ask my mom.

  17. 17Confused Dude

    I always thought that gravity counteracts centrifugal force, and keeps us from being thrown off of the surface of the planet. If his proposed model were true, wouldn’t gravity add to the centrifugal force, rather than counteract it? So, assuming that it were still possible to live under such conditions, how exactly would giantism be encouraged in the Inner Earth?

  18. 18Mechi

    Wait, is there breathable air on the inside?? Wouldn’t the core sun consume all oxygen? And the constant baking in the twilight sun the ocean would make the air pretty moist. This comes to my own theory: Hollow Mould Earth, where everything is one big fungus. You can’t disprove it; thus it must be true.

  19. this would be impossible i dint read it all but the theory is all wrong if this was true we would have no gravity as we would have no magnetic pull we have this because of the liquid center is made of metal that is magnetic and pulls us around the sun and in between each planet + if this were true then a volcano wouldn’t happen as there would be no magma but if people believe this theory then this could meen if we force so much weight on one point on earth then it would implode…

  20. 20otherguy

    um see center of gravity is just that…a center…a point…not a line………only way to have a line for such a think would be to have an object extending in at least one dimension to infinity, and as a sphere for sure does not do that…sorry. he fails.

  21. 21Nightshade

    Hey Columbus, we have screenshots so it DID happen ;)

  22. Look on the bright side. If the guy raises money for the expedition to the center of the Earth, scientists everywhere could benefit from his discoveries. Everything we know about the center of the Earth is hypothesis and conjecture based solely on our knowledge of seismic waves. If scientists had access to samples from the center of the Earth it could change our understanding of microbiology and many other fields.

    In short, let the crackpot get his money, lead is expedition, and do some scientific study to benefit the rest of us.

  23. So can you please explain why we have different seasons if there is an internal sun…with the ground (our ground) and the so called under earths ground temp, we should not have a flux in climat like we do, with the inner sun and the real sun we should see temp changes ranging in over 100 deg through out the year… I say its bogus! but that is my and a couple other billion peoples thoughts on it.

  24. 24Dr spasticek

    Come surface dwellers I will lead you to victory to annihilate and overthrow the evil inner earth peoples

  25. 25investigator

    There are some definite proofs that there are huge holes on both poles.

  26. 26Someguy

    I dunno what’s crazier here. The theory itself or the reasons you all give that it’s not true.

    Confused Dude: the spin of the earth is so slow for such a large object that centripital force can pretty much be ignored. You would see minimal chance in weight between objects of the same mass no matter if they were on the inner or outer earth.

    Eyal: the inner earth would have gravity. Anything with mass has gravity. The harder thing to swallow is that the crust (800km thick) by the theory would have enough pull.

    Mechi: the inner sun would be the equivalent to lighting a match in a large room. There’s so much space there it wouldn’t burn the oxygen as fast as it would be produced.

    Snow dog: Everything with mass has gravity. Magnetic pull has nothing to do with gravity. With a spherical crust (and molten mental center) we would have the same type of magnetic pull on the outside. The inner earth however would have it’s poles switched. And, only in theory you could cause the world to implode. The amount of force you would need would be astronomical. Experiment: get an egg. I’ll wait……

    Okay, now take that egg and hold it in the palm of your had and try to crush it like you were trying to crush it. I bet you can’t. It’s incredibly hard and it’s only partially spherical. Take the theory’s crust at 800km thick and you’re looking at a planet to planet collision to cause an earth implosion.

    James: With a crust of 800km, we would still have 600-700km of magma.

    Andy: cut holes in the top and bottom of a tennis ball. Now burn a match inside. You can’t feel the heat through the tennis ball, but you can at the openings. This is how it would work. An 800km thick crust would pretty much insulate inside from out. You would only see a change at the openings of the north and south pole.

    otherguy: gravity is not a “center.” Any amount of gathered mass has gravity, including you. You don’t have a direct center. We only think of it this way because the only things that have enough gravity to affect our lives are giant spheres (planets, stars, moons). With a hallow earth, the crust at 800km thick would be the dominent gravitational force in our lives and it would pull you perpendicularly to it’s middle.

  27. So how does he explain volcanoes then, and even if he did somehow pull together enough money and equipment to do this trip, wont he just get fried once he gets down deep enough.

  28. 28Richard

    me ? I am “doughting Thomas ” show me the PROOF ten only maybe i might believe along with the easter bunny what crap ?????

  29. 29afro joe

    wtf any one who believes this is on crac

  30. 30Different point of view.

    Have any one of you gone to a Carnival? I have and while there I had once gone on a ride called the Gravitron. Now let me tell you… this ride looked like a sphere and I walked inside it and stood against the walls of this sphere. It started to move(like the earth moves around). As it went around I was pushed up against the walls.. (it created centrifugal Force… or a sort of Gravity in of itself) So… wouldn’t you think ‘PERHAPS’.. that ‘IF’ there was an ‘Inner Earth’ it does make sense that there would be a correct Gravitational pull and they wouldn’t be floating all over the place.

  31. 31Dave Wells

    The earth may not be hollow, but the concept should be studied as far as gravity is concerned. Question: If you drilled a hole all the way through the earth and and measured the gravity as you traveled through the hole, you might find a surprise. The old theory was you would be weightless when you reached the center of the ball. You might find the weightless zone near the surface. 1/2 of the mass is quite near the surface. Volume of sphere = 4/3 pie x r3. If mass attracts, when you reach the center, you would be away from the mass in all directions. Your weight should be zero. Moving away from the center, you would be drawn toward a point somewhere between the center and the surface where your weight would again drop to zero. If true, something should weigh less at the bottom of a deep mine.
    If true, a black hole is a lot different than we think. Question: does mass attract? Is there something pushing instead of pulling. Maybe objects absorb ether and that is what drags everything toward the earth and sun.

  32. 32its a joke

    i bet you that someone just made up this theroy just for fun just to see if they could get people to believe it.

  33. 33erik

    why does the federal government not allow some caves to be entered and why do any and all pictures of the poles not show what apollo 8 and 17 show the hole at the north why did admiral byrd fly into the pole and give a radio broadcast while doing it and why did all publications of said trip mystriously vanish before hitting the news stands and where not recovered and the plates for the story so baddly damaged they could not be diphsifered

  34. 34Sam

    Using logical alone, look at the theory.

    Acoustics would shatter the world. As would earthquakes. Tectonic Plates wouldn’t work. Except biology, almost every other scientific study disproves this theory.

    ESPECIALLY the ‘we live on the inside’ bit. Then there wouldn’t be a horizon.

    Sound waves don’t lie. Just let it be that sonar and other sound bouncing systems are right in detecting what lies below, they worked on everything else, why not now?

    AND if this was some kind of conspiracy about keeping it secret (which someone was probably about to say) then we wouldn’t be having this discussion and half of you would be in government holding cells.
