In 2007 , a valet de chambre plan to go on a voyage to the North Pole to find the " gateway " to the shopping centre of the Earth , spur on by his understanding of the " Hollow Earth " hypothesis which had been disproved in 1774 .
Back before we really know what was hold up on beneath our fundament , there were theory . In1692 , astronomer Edmond Halley contemplate in a newspaper that the Earth was vacuous . Looking at the Earth ’s magnetised field , Halley observe that it was switch and variable . He consider that this was because the Earth was vacuous , and the magnetic fields were being throw off off by three intimate " cuticle " within the Earth , each with its ownmagnetic poles .
Halley imagined the objection of critic of the theory , including that the outer shells could crumple and descend with gravity onto the inner circle , divulge the control surface to the mole people below , essentially like this :

Halley believe that the case were “ lined throughout with a Magnetical Matter , or rather to be one smashing Concave Magnet ” and so the scale is kept up , given that magnetics is a strong force than gravitation .
Really running wild with the hypothesis , Halley proposed that there may be life down there , arguing that otherwise , it would be pointless .
" Since it is now take for yield that the Earth is one of the Planets , and they all are with reasonableness supposed inhabitable … Why then should we think it strange that [ this ] portentous Mass of Matter … should … serve [ only ] to support its Surface ? Why may not we rather suppose that [ it] … is so dispose by the Almighty Wisdom as to give as great a Surface for the use of living Creatures as can consist with the conveniencey and security measures of the whole , " hewrote , adding " we ourselves , in Cities where we are exhort for room , commonly work up many Stories , one over the other , and thereby lodge a much greater multitude of Inhabitants ” .
Halley , and other later proponents of the Hollow Earth theory , were wrong . Halley at least was working with incomplete information – with serious data point on the Earth ’s magnetic arena , he might not have mat the motivation to excuse it by having the Earth become an onion .
There are many variations of Hollow Earth theory , some of which propose – of course of action , without evidence – everything from there being an underground Kingdom calledAgartha , or that there are Nazis scupper inside the hollow quad and biding their meter . It ’s not known how either group would get things like " vitamin vitamin D " or " food " in this scenario . Some variation say that we are living on the interior , and the star we see are on the other side of the shield
They have of class all been disprove . We have a fairly practiced idea of what is going on inside our planet , Browning automatic rifle for a few mysterious and ancientstructures lurking within . The Earth is not hollow , but made up of the crust , mantle , and an outer and inner core .
The first experimentation to shew the Earth was not hollow took place in1774 , when scientist used a mountain in Scotland to calculate the denseness of the Earth . The team show that the sheer volume of mount Schiehallion attracted pendulum towards it . Using this and surveying themountain , they were able to calculate a rocky density of the Earth .
We now know that the Earth has adensityof about 5.5 grams per cubic centimeter ( 3.2 ounces per three-dimensional inch ) , Andrew Campbell , a professor of geophysics at the University of Chicago explicate toPolitifact , while the intermediate rocks we ’ve detect at the crust press 2.7 gramme per cubic centimeter ( 1.6 apothecaries' ounce per cubic column inch ) on average . render this discrepancy , we can assume there is affair below us , and it ’s a lot denser than the surface .
Since the mountain experiment , we have come up with much more sophisticated agency of looking inside our planet , utilizing earthquakes in a proficiency know asseismic imaging . When earthquake occur , waves of energy are sent out in all directions . By quantify the tremors from several locating at the surface , scientists can make a single-valued function of the Earth ’s inside . Since rocks and liquid within the Earth are of different densities , the undulation move through them at dissimilar upper , allowing geologist to figure out what type of material the wave are going through . We have found some coolheaded and unusual features using this method acting , but no hollow spot or mysterious underground kingdoms .
Nevertheless , in2007 , one generator of a Hollow Earth script planned to journey to the North Pole to bump the private entranceway using an methamphetamine hydrochloride - breaking ship , but the projection was canceled , much to the dismay of the methamphetamine moles , exist on the shell below .
