As somebody with a good amount of geophysics training, and somebody who know physics well, I would contend that this theory is bunk. Geologists are
really "interesting" people, I went to school with quite a few. To say that the earth has an opening in it that leads to a hollow core is
ridiculous. The law of gravity comes to mind as to why this is. Considering that the weight of the earth's surface pushing down onto a hollow
sphere would mean two things.
1.) that the material (no doubt undiscovered) that makes up this spere has such strength that it could resist the crushing force of the earth's
interior liquid mantle, and the earth's crust.
2.) that an inert gas exists in a pressurized environment sealed within this chamber negating the crushing force. Like squeezing a tennis ball.
The gas would sustain a pressure of thousands of atmospheres, and probably be unbreathable by anyone venturing to this realm. The air pressure alone
would be enough to kill a man, not considering its chemical composition.
Not to mention that the calculation of the earths mass, diamether and dimension would yeild and incorrect gravitational calculation. The acceleration
of gravity at the earth's surface is roughly 9.81 m/s (or 32 ft/s). This means that the estimated density of the earth by geophysisicists would be
incorrect. Geophysicists proved that the core of this planet is part liquid and part solid, by observing the effect of seismic waves traveling
through the different media. If the core was hollow in one area there would be a disruption in the flow of these seismic waves, and the results found
would not have registered. This is why there are Primary earthquake waves, and secondary waves. The primary waves radiate across the crust,
transfered quickly through the solid material. And secondary waves which travel more slowly through the liquid core and the "plastic" mantle. This
is how they pinpoint the epicenter of the earthquake. The density of the medium waves travel though determine thier speed. Multiple sample sites they
can pinpoint the epicenter of the earthquake.
This expedition is doomed. The mantle, has a consistancy of melting plastic, and the outer core is a liquid. Good luck finding a tube leading to the
solid iron core. Hope I saved somebody the 20,000 clams to go on a wild goose chase. They have a better chance of finding santa claus and his
reindeer up there.
