Has it necessarily been proven that the earth is not hollow?

Question

Even if there's just an itty bitty little space the very center? Has it been proven that it's solid ALL the way through?

Answer 1

proof as in, we Journeyed to the Center of the Tootsie Pop?  no.

but here is a great article that explains what you get when you dig a deep, deep hole.

(read it, its even more interesting than one of Brant's explanations!)

Answer 2

Yes, there is the Inner core, which is solid, then the Outer core, then the Manle, which is pretty much most of the earth, and is mostly magma, aka lava. Then the crust, where we live.

Answer 3

It is known that no very large cavity inside the Earth exists. Scientists have recorded the transmission of shocks from earthquakes and nuclear detonations as they pass through the Earth, and if a large empty space existed, it would clearly show up in the results. It is technically possible that a small space could exist, of course, as it would be too small to show up on the readings, but scientists know of no good reason why there should be such a space, and at any rate it would take some unknown and extremely strong and heat-resistant material to hold the cavity out against the extreme temperature and pressue in the interior of the Earth.

Answer 4

I don;t think that it has been positively proven, because we have never actually been there we can't say for sure. But there is a lot of evidence to suggest that it is very dense at the center of the earth. I think that sound waves has been one of the main ways they have found out a lot about the center of the earth.

Answer 5

Yes. We have "sonar' data. Besides,

No known material could come anywhere near standing  the

stress of maintaining an "itty bitty space at the very center".

Answer 6

The Earth is most definitely not hollow.  Seismologists measured tremor patterns from earthquakes and the evidence is pretty conclusive.

For more info look up Snell's law and seismology on Google.
