Hollow Earth May Be the Weirdest Theory of the World


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!

  4. 4jczubach

    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!


    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.

  10. 10Eyal

    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.

  35. 35rob

    been watching the so called expedition for fifteen years! every year they put it off till the next year- its a money grabbing enterprise ! fun to read about though

  36. 36Melinda

    It’s possible that the earth may indeed be hollow since we don’t know all that much about gravity, what it is really, and look at how stars like suns age and change becoming expanded and turning into like nothingness yet still having the gravitational effects, so people under the crust of the earth would feel the push of gravity on their part of the earth as we feel it on the outside of the earth, we don’t fall off of the earth no matter which part we walk on, the northern hemisphere or the southern hemisphere, we still feel like we are standing upright but someone must be upside down as compared to the other people in a different location. I definitely have dreamed of a place with giant vegetables etc. like that place must have in the inner earth. It would be strange though with those people being so tall and most of us being so short compared to them. I think i’ll go see the movie Journey to the center of the Earth (the new one). Lava probably just comes from pockets of it in volcanos down to a certain depth in the crust maybe less than 800 miles down from where we are. I think i will study geology. I can’t wait to find out what they find out on their expedition. Maybe they will come to our aid in the coming days, those people, the lost tribes of Israel. I would love to live down their in paradise with them someday maybe. Jehovah is God. it is true.

  37. 37jay

    to anyone who disbelieves there is an hollow earth or existing cavity are brainwashed offsprings.You only
    know and accept what you have been educated to believe.
    If you live in a home,house or dwelling is it solid where you can not move around? you have different levels which will be upstairs,downstairs,then what is remaing below – an basement.these are different levels as is the earth.It is not solid!there is a warming sun inside as is what you see when you step outside your front door.This internal sun sustains all living life and componetizes gravity unlike what you believe in mainstream scientificnism.Fact is,all planets or hollow.And condition and quality of life is far better in most cases when you have shelter over your head and protection from harsh climate seasonal changes or the ones that remain staionary either cold or hot,or too hot or too cold.Bottonline,the government have you all fooled!There is life inside and even a wonderworlds but the mass population will never go there until we have a mass ascension wake-up.

  38. 38Nate Day

    First off, I’m want to say that I don’t subscribe to the idea of a hollow Earth. With that said, there seems to be a lot of problems with the idea of a “center sun.” As Someguy mentioned, if there was a sun at the center of the inner Earth it would have fizzled out long ago and it would not have produced enough energy to sustain life. This is true, but the concept of the center sun is not the same as the concept of our sun or other stars in the universe. As many people know, everything in the universe emits radiation. On the outside of the planet the radiation pushes outwards through the atmosphere and into space. Conversely, in the inner Earth there would be the same amount of radiation escaping outwards, but instead of dissapating into space it collects in the center of the Earth, producing light and warmth but having no mass. With that theory, the sun would stay at a constant temperature and would never burn out until the rest of the world stopped releasing radiation, which it never should.

    Again, I’m not sold on the idea of a hollow Earth, but I think people should try to accept that if the theory does have flaws, they probably aren’t going to be able to discover them by reading one small article and watching one 10 minute youtube video. If these people are actually serious about their work they probably would have covered those basic logic problems.

  39. 39foreveridiot

    Let’s start with some simple truths. At the center of our planet, gravity is pulling outward, toward the surface. While the mass of the surface, and all the mass around our planet is being tractored toward the center, there is a mean line between the center of the planet and the surface, where gravity reaches a null point, due to the opposing gravitational forces of the heaviest mass. An off-center cancellation–if you will. Case in point, there is no possible way that the entire core of our planet is “solid”. It may be gasses or liquid, but it is not solid. It is not empty. So, it is not hollow, but there may be gaseous expanses within that are rather large. The earth has been cooling for 4.5 billion years, or more. It is unlikely that anything extremely hot, i.e., 20,000 degrees F exists inside the planet, anywhere. While temperatures at one time far exceeded this. If the planet were solid, we would be cooking now if they still did. The heaviest metals will be beyond the mean gravitational point, nearer the surface, but not near in terms of our current technology. The lightest metals and gasses will be in the center, due to the low gravity at the center. These facts support a gasseous “hollow” near the center. They do not support a large, vast expanse of emptiness. However, the Moon has played a part in the ‘stretching’of our surface. So, there is a possibility there is a very thick viscous layer of liquid and gasses under tremendous pressure, from BOTH directions, enabling the surface of our planet to ‘grow.’

    People who believe in a “solid” core planet are not thinking things completely through. Any great mass (liquid or gas) under extreme pressure will reflect a seismic wave.
    So, there are probably numerous layers, separated by more solid matter, that are liquid and\or gass as we journey through the Earth. One thing is for certain, the pressure is immense. It is not a place we can go. Not now, probably not ever. That pressure is playing a role in the expansion of the surface. So, in closing, the theory of a solid core is bunk, and the theory of a hollow core is bunk. We live on a planet of many layers of strata, both liquid and solid, under extreme pressure, and it is constantly changing shape.

    i was checking out the site and i am very intrested in finding more information on the whole hallow earth theroy and was wondering if u could direct me in the right direction and when was this expectidion going to take place

    All you trying discredit, sound like flat-earth supporters of not all that long ago.

    Let them try, if they fail so be it. You’ve lost nothing, and you can have a good laugh.

    People are free to believe what the like. Or are you scared that some established “truths” might be broken.

  42. 42Melisa F.

    Man! i have to do a stupid report on this but i do actually think that it is an interesting proposition for the earth to be hollow, you all should read the book then watch the movie the MOVIE is a RIP OFF!

  43. 43wow

    All great dicovers comes with great effort and If not wrong people would make a joke of people that tought the earth is round
    I’m not saying I belive it but nothing has prooved it wrong yet…
    lets wait and see what these peope find
    If they are right I’m buying a boat and sailling there


  44. 44Anne

    Maybe this theory is correct. This might be where our unexplained sightings come from (lockness, ect). Maybe these creatures have access from the center to the surface not found by man. That might explain why they have never been captured. If there is life on other planets with or without gravity, why not in the center of our own planet? Besides, nature always finds a way.

  45. 45Mason

    Well i’m not saying yes or no to either theory. Because taking into consideration that seismic readings could be widely interrupted since such a massive distance is to be covered. Like if there is a hollow earth as stated in theory. Then perhaps the seismic readings that read the “less dense portion of magma” may actually be interference from the device itself with the vibrations of the out crust, so the return signal will always be distorted in some way. So both theories are plausible. Hell a planet could even been dead stars that crust over from sudden particle cooling when the star dies out and the heat disperses. There is simply too much information to read into. So rather than tell one that the other is wrong. why not keep both theories in mind so we have a broader knowledge of what to look for in future investigation?

  46. 46Justin

    People so absolute, cant allow spectrum of theories on what i presume no-one here can know. Some points to consider…laws of gravity, notions of attraction and repulsion are up for review as are seismic data and even what powers the sun. Scientific data and mediums of expression controlled and corrupt. Education designed to stifle imformation and ability to reason.Many reasons to doubt promulgated stories of how things are regarding earths material composition. Historically other older civilizations have spoken of inner areas of earth, including referencing polar openings and sun as well as inner civilizations. Also much scientific evidence that earth and other planets may be hollow. If you do deep research you will find imformation anomolous with current universal theories. Beware when ideas or imformation rejected as scientifically implausable and especially when sarcasm and putting down people involved: imformation sources such as web polluted with people whose jobs are about product placement of ideas. Then there are too the people who just think in narrow ways and disbelieve anything that seems fantastic. Dont believe this? The national broadcaster of the place where I live has recently instituted a policy whereby any idea or imformation which is deemed to be not commonly accepted is suppressable. Ie. in our supposed democracy powers of our reality can keep news from dissemination though it may be of interest to public… because it is news to the public. Anybody out there with an interested and open mind, as any scientist should have, will not assume this possibility, hollow earth, is meritless because of terms such as discredited or impossible as well as slanderous comments about peoples intelligence. Interested people may well want to observe that planets and moons ring like bells when struck, something solid bodies should apparantly not do. Also over the years have come out anomolous light heat and moisture seemingly escaping fom many planatary and moon type bodies. Futhermore some scientists and other investigators have questioned sciesmic evidence as proving conventional wisdom as to solidity of earth. I dont know the truth but suspect earth is hollow, evidence to someone looking at this for years is substantial, but then i am a sceptic of much of what we are told and taught.

  47. well, let’s see now. First, we have Chiggers then next we have hallow earth. I’m sure Chiggers are the worst of the two but then again, who knows for sure?

  48. 48lowell

    There has been a siesmic picture proving that the earth is hollow.

  49. 49Blar

    Ok so to everyone so narrow minded to think science is perfect and evrytime they are told is true, how about you go and actually try to prove these researchers wrong by actually looking all over the pole and not finding a hole in earth. I don’t really believe the hollow eart theory but what’s the point of trying to say it’s wrong if you can only look on the Internet for information.

  50. I am very interested in this view of our forgotten ancestry or …. In any case I have been following this theory for about 25 years after running into a book by Ignatius Donnelly. Please keep me updated If there is need for a cook or person with special “senses” would love to participate in the expedition.


  51. 51Rosalio

    That makes no sense. If a human were to go to the great abyss which is about 5 miles deep your body will be crushed by the force of gravity. Basically it would go inside out and explode. So therefore humans couldn’t live under the Earth’s crust. They would die before they get close to a possible hollow part of the Earth. Robots ha ha ha little green men? Author Rodney Cluff sais that aliens live in the inner Earth and are 1,000 years ahead of our time. When people see little green men they are robots. ha ha ha. http://www.youtube.com/watch?v=1soEAbWm4qc&NR=1

  52. 52pauline

    maybe its true that earth is hollow!we never know because until now the science have no proof what is the center of the earth.

  53. 53Forests

    The earth is hollow it is a proven fact. I am publishing a book on it very soon.

  54. 54Graham

    For a solid earth, gravity decreases until it is zero at the center. At any point inside a sphere, the pull exerted by all parts of the solid shell outside this point cancel.

    These are some simple results of integral calculus, any graduate mathematician could give you the proof.

    What was fun to me when I figured it out: If you have a tunnel through the center of the earth, how long would it take to fall until you came out at the other side?
    (Increasing speed then decreasing, decreasing acceleration then increasing deceleration). Answer: about 47 minutes! Assuming no resistance, you can survive the heat, and the pressure is held back by your force field :-)

  55. 55I AM

    I think its funny how the people like Rear Admiral Richard Evelyn Byrd died a year later after exposing his findings of a hollow earth and how his reports were suppressed extremely. Or how Steve Curry died just before his expedition to the South Pole. Reflection seismology? Get over it, your not a seismologist and even if you were you have no 100% proof that your equipment isn’t flawed. No one really knows anything, there’s no such thing as a fact, humans have deluded themselves into believing their superior to one another somehow. Most Americans think drugs and surgery are cures when really they just relieve symptoms rather then work on the root cause to the problem because of the people in charge and big pharma, have spent millions of dollars on dis info campaigns just to delude your mind. So if this hollow earth theory were true, indicating all governments would be involved, indicating there’s been a one world government for a long time, I’m sure it would be quite easy to delude everyone. Wake up sheeple, never stop asking questions or be prey to ignorance.

  56. 56jonathan r

    i guess the real question here is ….
    “is everything that we have been thought the reality of things?, or is it teachings that keep us from evolving ? as we have been thought that everything we know is as it is and there is nothing beyond of what we have learned?” ..just because a person has a phd and read a million books does not mean that he knows. Part of learning and knowledge is through experience.. have you dug to see whether the earth is hollow? ….Oh yes the books say an he says and they say that the earth is not hollow..Maybe what they read and heard was written by someone who based he’s theories on just math and imagination.

    The fact s remain that the theory of a hollow earth has not been proven wrong since there has never been any research , expeditions or investigations into the mater.
