It's just a theory, although hollow is relative. How about a reduced pressure and/or lower density interior? ~ BG

Hollow is defined, not relative. > How about a reduced pressure and/or lower density interior? The pressure at the center is created through compression, not gravitational attraction AT THE CORE, rather the matter trying to get TO/THRU the core via the resultant vector created by ALL of the matter of the earth, not just at the core. However, do to this compression the matter at the core will have a higher specific density, thus a bit more gravity than the same material would have without a large mass trying to press through equally from all sides.

Thats really odd, because in deep underground caves or mine shafts, other than the expected atmospheric pressure increase thats obvious and somewhat minor (<42% increase per 3.5 km depth unless you plan on artificially cooling that column of air in order to get a 100% increase per 3.5 km), theres hardly any other significant geology pressures for our physiology to contend with, including while swimming or scuba diving in those deep underground lakes or aquifers, and theres certainly not any big increase in gravity (if anything it only measurably increases ever so slightly), and theres certainly no objective way of telling if the inner core is merely that of a dense shell thats hollow inside, or not. http://nopr.niscair.res.in/bitstream/123456789/2506/1/IJRSP%2037(1)%2064-67.pdf Just because the pressure within the surrounding crust/bedrock is increasing by roughly something less than 300 bar/km doesnt mean squat, especially when the deepest Russian well started getting into lower pressures and/or somewhat less rock density at depths below 10 km, and at that kind of shaft depth theres only a relatively slight atmospheric pressure increase. A true geode pocket thats mineral/glass sealed and situated deep (say at 10 km) might even conceivably offer less internal atmospheric pressure than its surroundings until its broken into. A geode formulated layer or pocket with any sort of fluid(s) inside is also technically hollow, because that fluid or even whatever less density substance(s) (such as sodium) can be easily removed and/or displaced by hydrogen, helium, methane or some other gasses. An interior cavity of crystals can even be easily dissolved or simply fragmented and removed or reutilized as is. On the backside or farside of our Selene/moon, under that extremely thick and robust basalt crust thats also rather unusually mineral saturated, mascon populated and otherwise very paramagnetic, as such could be offering quite a large volume of a hollow interior to work with. Being situated 100 km underground might seem downright testy, but on the moon its actually kind of nifty to ponder.

The fact that gravity increases measurably in deep caves/mines tells you that the interior of the Earth is denser than the rock above you. Otherwise gravity would have already begun to decrease.

Caves and mine shafts are cavities in the crust. The only pressure that would be evident there would be atmospheric. The pressure inside the Channel tube is relatively the same as that on the surface, as well as that inside of a sub at great depth. The pressure on the walls of the caves/mine shafts, or sub, is much greater. Since they are solids that pressure is contained by the structure of their substance and does not flow as with a liquid. However, if the pressure is great enough the structure of either will fail. A cave will collapse and a sub will implode. Increase the pressure sufficiently and the friction will cause any solid to lose the molecular bonds that make it a solid. 2) A gas does not behave like a liquid or a solid. Nor does a liquid behave like a solid. 3) What happens to a can of air that is immersed to a depth of 3.5km in water? Now, drill a hole that deep in ice. Place the can down there and slowly fill with water, letting the water freeze 1mm at a time. What then happens to that can? |
