Nope. There is no gravitational pull towards the centre at the centre of the earth. The pull is equidirectionally outward. Therefore, there is weightlessness at that point. This effect is exactly the same as the weightless nodes in between the earth and the moon. If you don't believe me look it up in some engineering texts that have questions on the subject. Some will have Newtonian equations to do with hollowed out models of the earth in various sections. As net-directional gravitational fields diminish, the net differential between elements of different SG diminishes too in force, and the compaction of the materials, which no longer exhibit liquid traits, no matter the temperature, does not allow penetration of heavy materials towards the core in lessening gravity. The mass is not fluid enough, nor is there enough central tendency pull, or differential mass weight for sinkage. Ergo, it is much more likely that heavy materials are caught in bands around the earth far out from the centre, This is supported by the relatively heavy chromite-harzburgite layer which is only 150 miles down in the earth's mantle.

off topic (or) You're kidding -- right? . To:Zardoz From: E. Charters Pressure comes from gravity. Without it there is none. As you go towards the core, there pressure due to gravity becomes less as it is more and more balanced by [mass] accumulating "behind it, or towards the surface" . To:E.

(or) "His Divine Shadow" Stanley Tweedle and escaped "love-slave" Zev returned to the ruins of Cluster in the Light universe to search for protoblood for the undead assassin Kai. The infamous scientist Mantrid created an Earth like world, but since it was a copy from the Dark universe to Light, all human life forms were lost in the transfer, and certain irregularities encountered, of which we can use, as follows. A hole was created that started in China, went directly through the center of mass of this planet, and up pop'ed as a hole in Wichita, Kansas by chance at their famous Bronx Zoo by chance in the elephant pen by chance under elephant taking a number 2 soooooo this 100 pound dung fell into hole through center of Earth and as it fell down this hole of only air its velocity was limited to equal a number such that the pull of gravity equaled the opposite resistance of pushing into an air at rest but wait not we need do as lower the dung went down towards center of Earth it's weight on bathroom scale decreased as at surface at location Wichita, Kansas it was 100 pounds and now miles lower into Earth, it's weight is 99 pounds bBut Wait the air is less dense or, less resistance so, lets assume that max velocity reached when acceleration was prevented is 100 mph a guess since i never knew what speed that geologist who fell out of hello-copper Bre-X style reached as he reached Earth but ok, the turd as it reached 1 mile above Earth's center 100 mph air almost a vacuum turd weight about 1 gram annnnnnnnnnnnnnnnnnnd zoom pass center at 100 mph going going towards that China hole but never reaches it since some energy gone into heat so, it stops at about 1 mile below China's hole and NOT round and round we go but, back & forth down & up & down until years later at rest, the turd and now the elephant craps a new after it was frozen in time for these years and yes splat! at Earth's center 100 mph turd of zero weight hits at rest a turd of same mass or new game and lets fast forward 1,000 years so we have at Earth's center at rest now, no motion 500 elephant dungs each Wichita, Kansas side and China's side with each side total bathroom scale about .003 grams like if you were at Earth's center being under water with pressure .003 grams force on all of you - keep mouth wide shut so, lets move very fast forward a zillion years and a zillion dungs have fallen and now elephant's long life eneded and then after a while, silence no more splats no more movemints and from top of both holes to center all elephant dung and you is at center knowing first mile up weight is 1 gram next mile up, 2 grams ... that dung peice 100 miles up weight is 1 pound and finally the dung at surface, 100 pounds so add them all up and get i have no idea. Pressure at Earth's center. or Life at Earth's Center or Be careful what you wish for or hope to be, as The Center of the Universe d:oug
