Every planet has to have a core. between the pressure of the atmosphere and gravational pull, if the earth was hollow then it would collaps. how do we have earthquakes, eruptions, tsunamis if the earth is hollow. another question. how would we have oceans with the depth and compasity to hold underwater mountain ranges and still at the bottom have sea floor spreading? there are five layers of earth
Crust- surface like an eggshell (very thin)
Mantel (pasty hot magma)- thickest layer in earth, approx 365 kilometres thicker than the thickest part of the crust.
Outer core- (liquid hot)
Innercore- solid. eventhough it is hottest part of earth it is solid because of the intence pressure.

I really think that there are large hollow places in the earth,
but the evidence shows that there are not any that big
from the linked web page
"As seismic waves radiate outward from the epicenter of an earthquake, their speed and other properties are affected by the different materials they pass through."
this is how we know what is in the center of the earth, I have seen the data.
if it was hollow, meaning filled with air, it would have shown up in the data, but a very large cave might not show up.

I even have not researched this question so i won't be able of offer you any references. yet from my own wisdom, I see no logical reason the earth may well be increasing. There are no longer organic strategies that could reason the earth to amplify. If something, one might assume the earth to settlement.Why? a million. The earths center is cooling. Cooling of the middle might reason the vast globe will survive to settlement through fact maximum components amplify whilst heated. Water vapor and different gases trapped close to the earth's molten center will settlement whilst cooled, besides through fact the molten rocks themselves. 2. loss of water vapor. The earth is consistently dropping gases and water vapor to area through heating from the sunlight. The sunlight's rays excite molecules on the better surroundings. in specific circumstances a gas molecule will attain adequate potential to flee earth's gravity. Over billions of years, significant parts of gas (inclusive of water vapor) will leave earth and not in any respect return. 3. Loss through fission reactions. Radioactive components interior earth are decaying over the years and freeing debris which will leave earth. So fairly than amplify, my concept is that the earth is shrinking yet no longer adequate to rigidity approximately.

The proof of a core, including composition can be infered by the magnetic poles, and the effects of the earths gravity on the moon. This can be used to prove the existance and compositions of planets very far away. No ping-pong ball space objects have been found yet. Gravity makes sure of that.
Sorry.

In the upper mantle there are hollow places
but the earth is NOT hollow in fact it has a
very heavy and dense center core

If you are thinking of Jules Verne, that's just science fiction. There is no evedence of the earth being completely hollow, and quite alot to the contrary.

None that I've heard of. Since my mother is a HUGE science geek, I'd be the first to know if such evidence had been discovered. :P

Is there any evidence that it isn't?
