It's just a theory guyz! All theories are equally plausible!

From Wikipedia; contrary evidence to this theory.
Gravity
The best scientific argument against that of a hollow Earth or any hollow planet is gravity. Massive objects tend to clump together gravitationally, creating non-hollow spherical objects we call stars and planets. The solid sphere is the best way in which to minimize the gravitational potential energy of a physical object; having hollowness is unfavorable in the energetic sense. In addition, ordinary matter is not strong enough to support a hollow shape of planetary size against the force of gravity; a planet-sized hollow shell with the known, observed thickness of the Earth's crust, would not be able to achieve hydrostatic equilibrium with its own mass and would collapse.
Someone on the inside of a hollow Earth would not experience a significant outward pull and could not easily stand on the inner surface; rather, the theory of gravity implies that a person on the inside would be nearly weightless. This was first shown by Newton, whose shell theorem mathematically predicts a gravitational force (from the shell) of zero everywhere inside a spherically symmetric hollow shell of matter, regardless of the shell's thickness. A tiny gravitational force would arise from the fact that the Earth does not have a perfectly symmetrical spherical shape, as well as forces from other bodies such as the Moon. The centrifugal force from the Earth's rotation would pull a person (on the inner surface) outwards if the person was traveling at the same velocity as the Earth's interior and was in contact with the ground on the interior, but even the maximum centrifugal force at the equator is only 1/300 of ordinary Earth gravity.
The mass of the planet also indicates that the hollow Earth hypothesis is unfeasible. Should the Earth be largely hollow, its mass would be much lower and thus its gravity on the outer surface would be much lower than it is.
Visual evidence
The deepest hole drilled to date is the SG-3 borehole which is 12.3 km (7.6 miles)[11] deep, part of the Soviet Kola Superdeep Borehole project; thus, visual knowledge of the Earth's structure extends that far.
Makes sense.

Gravity?
How does gravity work? We don't really know. We can define what it is as a field of influence, because we know how it operates in the universe. And some scientists think that it is made up of particles called gravitons which travel at the speed of light. However, if we are to be honest, we do not know what gravity "is" in any fundamental way - we only know how it behaves.

I just know we really don't know shit.. most of the science is based on speculation.. some grounded in facts but much more really hypotehtical. I'm sure we would be surprised by many things we don't know..
Hollow Earth wouldn't surprise me at all..
I don't buy there's someone living there but I wouldn't be shocked that it is hollow and has some kind of energy emanating inside.
But I highly doubt people would live inside because we would see them in The Core.

The Diary of Admiral Byrd...
http://www.v-j-enterprises.com/b…
Interesting Read...."We are crossing over the small mountain range and still proceeding northward as best as can be ascertained. Beyond the mountain range is what appears to be a valley with a small river or stream running through the center portion. There should be no green valley below! Something is definitely wrong and abnormal here! We should be over Ice and Snow! To the portside are great forests growing on the mountain slopes. Our navigation Instruments are still spinning, the gyroscope is oscillating back and forth!"

What a bunch of horse-shit, and a terrible thing to assign to someone as having said. Great story, but fiction, and a slur on the character of Admiral Byrd to have him associated with it.
I blame religion.

i just finished reading 'journey to the center of the earth' last week. way cool. then, i saw the trailer for that brendon frasier movie and almost punched the tv.
