center of the earth

I don't really know any details, but I'm pretty sure that a detailed study of Earth's gravity - surface as well as satellite tracking - excludes any chambers within the Earth's core, and are consistent with (or even let folks calculate?) and increasing density as you go deeper.Besides, how would that ol' Debbil get those folks down there to Hell's chambers with no tunnels?

Perhaps because it's real tough to find anything that's liquid at room temperature and a zillion psi pressure? Mineral oil, I know from experience, is solid at only 20,000 psi at 80 degrees F - that pressure's only four miles deep in the crust.

No. The Cavendish experiment measured tha attraction of two known masses at a known distance apart to each other, and compared that with the attraction of the Earth. No assumptions other than the standard Newtonian Law of Gravity. And we know that works, because we launch satellites these days, and track their orbits within inches. That, though you'll say "it's due to hidden chambers in the firmament", lets us calculate an accurate mass for the Earth. Real accurate.You're just being purposely obtuse, Cosmo.

It's very easy to derive when satellites are passing over mountains instead of valleys from their orbital behavior, and our biggest mountains are scarcly pimples on the Earth's surface - not even noticeable against your 1/4 sextillion tons.Go read a book. Maybe a ninth-grade science book.

No. They indicate that the Earth has a certain MASS, and that the balls were a certain (measured) distance from the center of that mass. The density is a calculated side-dish - we can get it from mass divided by volume, but it's unimportant in Cavendish's experiment.

Foul heretic! It's a highly, extremely, excessively compressed cowpatty at the center, surrounded by exceptionally dense, but only lukewarm, horsepiss. I wish we didn't have freedom of speech in this country (well, we may not, anymore....) so that we could prevent these deviant, diamond-worshipping theories like yours from being heard by poor, innocent schoolchildren.Who do I call, with Ashcroft going home?

New and proper, HAH! You're still omitting the giant, dense cowpatty that is at the center of your whole theory! Think of the poor schoolchildren!

Most importantly, it's DENSE liquid! It must necessarily be dense because there's rock floating on it! I really, really don't think that anyone can come up with a material strong enough to make a 3000-mile diameter geodesic dome that will hold a couple thousand miles of olivine up out of the cool water below it.Water can't get dense enough, no matter the pressure. Silicate minerals can't get dense enough. Iron can.

Sorry, it doesn't fit for density at all. The density of gold at room temperature is about 19 g/cc, about 2.5 times too dense for all the data. The solid inner core would need to be even denser, and, as a result, the known mass of the Earth would come out wrong.And then we have cosmological problems in getting enough gold to make a core like that - iron and nickel are as abundant as they are for a reason - they're the ashes of supernovas. Gold is just a trace contaminant in those ashes.

Well, your fun is over, then, because as you've been told several times now water isn't dense enough to sink to that spot, and there's no material strong enough to build your silly-assed 3000-mile diameter shell over the core to hold a mantle with a specicic gravity of 5 up out of a light fluid like that.Mods, can we get this goofyness shut down? Simple is repeating the same old stuff from 200 posts ago.

Good, clear post, Percy. I should work on patience... Let me add here: the most important way that we know this is because heavy stuff sinks! Any material with a greater density that that of its surroundings will try to settle to its own level. If you look for even a moment at the strength of material required for a "barrier" or "diamond shell" or what-have -you, you'll see that it just can't work! 1500 miles of rock, specific gravity 4.5, above a body of water under enough pressure to get it to specific gravity 1.5 will do as an example. That's (4.5 - 1.5) x 62.4 x 1500 x 5280 pounds held up by each square foot of this "barrier" - and if it's a couple of thousand miles across itself, it has several square feet of area!Look at what you're proposing, Simple. Think about it.

Hmmmm... yeah, hydrogen! It can get clear up to densities as great as 0.6 gram/cc, {Nature 416, 613 - 617 (11 April 2002)} aggravating still further the density problems you had with water. And when it comes to surface and combines with oxygen to give Noah his Flood....lessee, how hot is an oxygen/hydrogen flame again? 3000 Celsius?Why not use pressurized angel urine as your liquid outer core, Simple? You can just assign it any properties you want - it can always stay cool, no matter the surroundings, and can turn into seawater when it depressurizes! It can have any (variable!!!) density you need! Supply would be no problem - the angels can just drink Keystone Light to manufacture more!

It makes plenty of water! Isn't that good enough for you scoffers?

Pure hydrogen peroxide should be your number one target candidate. It'll even help your Fountains of the Deep break forth better. Y'know, to launch asteroids 'n' stuff.
