There is a new movie coming out that I saw a preview for. It's called The Core. It's about the world's core completly stopping and they have to make it spin again.
A. Can that happen?
B. What would really happen to the world if the core did stop?
C. How could we dig through over 3000 miles of rock, lava, and other stuff to get it going again?

The earth's core is in liquid suspension. As the earth turns that force is exerted onto the liquid, which translates some of that force to the core. In a nutshell, no it wouldn't stop.

In the event that it did stop, it would have to be started again with absurdly large magnetic feilds. I'm talking about covering the face of the earth with an electromagnetic grid.

On top of that, if the core stoped spinning, nothing would happen except that magnetic compases would have to be adjusted for the time of day to be very accurate. But we got GPS so it doesn't matter.

The effects would be devastating. The earth is surrounded by an lectromangetic belt protecting us from solar and cosmic radiations. It is caused by the rotation of the core and now we believe that the poles are going to go upside down. North will be come south, and south north. Even if all mankind united in trying to make the core spin again, it would be impossible. First we need to drill tor at least a few hundred miles, which would take decades of work, we need the most complex and most resistant of all heat-shields in human history and put that on some submarine ( beyond the crust everything is liquid ) go down around 5000 miles which would already take months, already survival is almost impossible for the crew inside. They need water, air, food, the good air pressure ( hey at these depts pressure must already be enough to crush the sub into a pepsi can ) and still there is 2 cores, the very solid and dense core, and the ultra solid and dense core, located 1000 miles below. How in the name of Christ are you going to even try to make this huge ball spin again? And still you must mke it spin at the right speed, and in the right direction. As I said, its humanly impossible. But the trailer of the movie was good so I think I will go see it anyway.

yep just about impossible. off topic though i have a huge poster of the core. its about 5 feet wide and 8 or 9 foot tall. posters dont sell on ebay:*(

Exactly what I thought, Whats odd is that to try and start it again they seem to be using absurdly powerful bombs to "jumpstart it". Oh well, thats hollywood for you.

Man, the core of the earth is the strongest thing on the whole damn planet. It must be the toughest alloy ever made. In my opinion, it can easily cut through diamond. Diamonds are dead plants having decomposed to the form of carbon, and having been crushed and heated to hunderds of degrees at depths of a few kilometers and under millions of psi during two hundred million years. The core is made of pure iron being crushed and heated at thousands of degrees at depths of seven thousand kilometers and under trillions and trillions of psi during four billion six hundred and twenty-five million years. I believe there must be a a big differences of particularities between the 2.

Bob, think before you type.

The core is iron with some other shit mixed in. In fact a good part of it is liquid. Iron is not that hard.

As for your little assesment about the effects on the VanAllen radiation belt, I can't decide if you are stoned or just stupid. The spinning has nothing to do with the magnetic properties. Do the magnets on your fridge need to spin to work? Didn't think so.

Prometheus, the VanHallen belt is fading away. It's no joke,the pole shift is imminent. A pole shift usually happens every 500 000 or so years, and the last one happened 780 000 years ago. The magnetic north is slowly going to russia. It's moving faster and faster, an evidence of the core instability. And by the way, don't you know anything about geology and geography? The 2nd core IS solid. Quite solid. Yes it's true that there are other metals in the core, but it's mostly made of iron. Even beyond its boiling point, the pressure just keeps the iron solid. Every planet except the giant ones has a solid core.

sounds like bob has seen one two many hollywood-psudo-science movies.

I didn't see it in an Hollywood movie but in a science documentary.

It's speculated that the Gas Giants have solid cores, seeing that pressure is what keeps the inner core solid, and Jupiter is huge!

Indeed, but it's not yet proven. The solid part of a gas giant, is no bigger than a moon. It's even speculated that they may have liquid cores.

There is probbly some super hot liquid iron or lead at jupiters core. If its small it may just be super dense...say made from a heavier atom such as (non-radioactive perhaps?) Uranium.

Where in that are you not being stupid?

While a pole shift may be on it's way, and the VanAllen (not Van Halen) radiation belt will be destabilized during a shift, that has nothing to do with the rotation of the core. NOTHING.

I hate to repeat myself, but think before you type.

The quote neither. The iron core itself as nothing to do with the rotation anyway. I was refering to the movie. If it was possible to dig to the core. My answer was no. End of story.

dont give up so easly... lol

let me intercept you.
even if u could dig into he core it would ring you nothing. Because i doubt that it will be an internal issue stoping the core. So You will have to do something from the outside.

To think of it... instead of digging couldnt we not enter by a volcano?

um i think you would only have to dig thruo the crust then "sink" tot he core. but what about all the magma currents underneath the corE?

I fail to see any logical purpose for trying too reach the core to restart its spinning other than it being a crappy rip off of journey to the center of the earth. And could anyone please explain how the theory that the earths core is composed of an outer liquid and inner solid mostly iron mass came about? Im just wondering what logic is behind it is all... always was just kinda told just accept it...

The liquid core theory came about through an extremly close examination gathered from siesmometers. When there is an earthquake there are different types of waves of movement. One type of wave(I forget which) travels through the earth, not around the curve. By analyzing the speeds at which this wave travels, it can be interpreted what sort of material it travels through. A wave traveling directly through the earth will have a certian speed, while it will have a different speed if it travels through the liquid part only. It has yet another speed if it doesn't travel through the core at all. By analyzing the zones at which these speeds take a drastic change it can be deduced that the a line from the epicenter of the earthquake to the boundry line will be tangent to the border between different substances. Hope that helps.

Bob--

Matter does not have to be "tough" or "hard" to withstand pressure. Think about it; if you seal a steel ball inside a titanium sphere (sealed EXACTLY; I mean that the only matter inside the sphere is the steel ball itself) and apply pressure (I'm talking about equivalent pressure from every possible point) then the steel ball should say the same; because there is nothing for the matter in the steel ball to "crumble into". If the atoms of the ball are already locked into a completely sealed position then there is nowhere they can go.

How do you think diamonds are made? Strongly compacted carbon under incredibly high pressure. The core is iron under pressure made by it's own gravity. ANY form of matter can be compacted UNTIL the form of pure neutron.

Where did you learn that retarded bit of information?

Diamonds form under extreme presure because that is the only way in which it will crystalize. Iron is brittle when crystalized, and at the heats it is at in the core it would be quite soft too.

youre talking about s and p- waves i forget which ones which at the moment

WTF? Suddenly i'm trying to picture an atom made only of nutrons... That seems interesting... what would be the result of that?

Neutron stars are a good example. They are only spinning balls of neutrons.
