Anybody know something about the "Hollow Earth theory" and what are the criteria therefore?

Question

Ever since I read "Journey to the center of the Earth" by Jules Verne about 13 years ago, I somehow believed the Earth isn't entirely solid and that life might exist in the interior. I also believe that everything in this universe are linked, such as the double helix DNA spiral to the galactical spirals. Is it possible that planets could be like a huge atom with a central core and free ranging nuclei matter? I know I'm a bit crazy, but how do we know for certain the Earth is NOT hollow? The deepest mine in the world doesn't even scratch the Earth's crust and I doubt that we can scan the Earth as deep as to the core. Isn't the assumed fact that the Earth is solid, not also just a theory until we can prove it?

Answer 1

I'm digging the hole now and will let you know as soon as I get there.

Answer 2

The earth is not hollow, only in the crust you can find some beautiful caverns full with life that may have inspired some of Verne's great books.
We know that the earth is denser going to the center. this is based on that we know the size of the earth 1,024,000,000,000 km^3 (sphere of 6400 km radius) and also the mass of the earth 6*10^24kg. So we know that the density of the earth is about 5.5 gr/cc. Nevertheless, the density of the crust is roughly 2.7 gr/cc.
We have very few samples of the mantle, so we know roughly its composition and density as well.
We also know that the denser the rock the faster the seismic waves propagates and seismologists know that the earth is not homogeneous but formed by layers of increasing density. They are: the crust, the mantle, the outer core, and the inner core. there is a shadow of the s-type wave that strongly suggest that the outer core is a dense liquid while the inner core is a dense solid.
We have no direct access to the outer or inner core, but based on its calculated density and in meteorites it must be formed by a iron and nickel alloy with another minor components.
With all this data we are certain that the earth is not hollow, but a lot denser at the center.

Answer 3

No, it is not an assumed fact it is a derived fact, brought about from the analysis and corroboration of numerous models and results in areas such as geology, seismology, physics, temperature and pressure gradients in materials, etc, and good old fashioned human reasoning

In short, the extensive study of the reflection, refraction and transmission of seismic waves ( produced from earthquakes, nuclear tests, etc) proves almost categorically that the earth is not hollow - although saying that, the exact composition is not known either.

In just the same way as sound needs a gas in which to travel ( sound cannot travel in a vacuum - did you ever do the alarm clock in a bell jar experiment at school ? ) seismic waves need a solid. Whilst they can travel to some degree in liquid they are virtually dissipated in gas, usually by being converted into sound waves.

Whilst I seem to remember that seismic data does show a limit of detection ( a useful analogy is to compare seismology to trying to hear one specific pin drop amongst the noise of 100 million ) - the incredibly high temperatures and pressures would render this a virtual impossibility.

In order to sustain a hollow structure, without any internal support, the outer material would have to be ridiculously super-dense and super-resistant to heat and pressure in order to prevent itself from imploding and, critically, would have to have been formed from the raw materials within the earth at the time of its formation. Logically therefore it would be possible to recreate that material under lab conditions, albeit in minute quantities. Such a material has yet to materialise.

Then again it could be made of some exotic dark-matter that defies logic and detection under normal ( or even paranormal ) methods

Answer 4

seismic data is used to determine the structure of the earth and think about it how the crust of the earth could form above a hollow? Would it just be suspended above the next part of solid matter?

And if the earth were hollo it would have been crushed by the weight of us on the surface and alos of the atmosphere. The book is a sci fi fantasy and not a factual book!!!

Answer 5

I am glad that I am not alone thinking the same about planets as huge atoms.

About thinking as the core of Earth is hollow I am not with you. I have read as the earlier Earth was a hugh ball of molten lava. As it geting cooled the heavy material gets sinking at the core of the Earth. The material must be iron and nickel. Thus, It can't be hollow.

Answer 6

I'm wondering if you picked up some information about the group of people that lived in Florida about a 100 years ago,they started a community out in the Everglades and that was their thing the earth was hollow and what we see up in the sky was really the crust. Now I wish I would of paid more attention to the lady that was explaining it as she had a large ''map'' that came from the community.I also remember her saying they were rich educated people. You got my curiosity up and I'm going to see if I can find anything on the web.

Answer 7

as waves of energy such as those from eatthquakes are sent into the earth the way they reflect and refract make very reliable guesses as to the density of the earth
plus the gravitational preasure of the earth-the same that keeps us planted on the earth instead of floating into the atmosphere-would collaps the eatrth if it was hollow.

Answer 8

The mass of the Earth can be estimated by measuring its gravitation force. Given the mass and diameter, it is highly unlikely that the center is hollow.

Answer 9

The Hollow EarthTheory has been proven to be untrue.

Answer 10

The core is not solid it is a liquid.

Answer 11

thas quite a good thought you have there. anything is possible.
