If the Earth's core vanished?

  1. Mar 31, 2015 #1
    What would happen if the core of the earth suddenly disappeared? Would the gravitational field it emitted immediately disappear because the mass at the center disappeared. Would the surrounding Earth collapse into where the core used to be because of it being pulled there or would a new center of gravity at another point be generated?

    Hi lputput
    welcome to PF


    since it cannot disappear, any speculation is probably pointless
    and not really within the realms of mainstream science that the Physics Forums deals with :smile:

    If a void just happened to appear in place of our core, then I'd imagine that the mantle and crust would collapse inward causing intense friction.
    I guess the changes in gravitation field would have an effect on our atmosphere, and the orbit of the moon. Loss of the inner core would likely cause a serious change in the magnetic field that currently protects us from the Sun. Shape of Earths orbit also would probably change.

    Odd question.

    In my opinion..
    If the inner layer that's left is still Rock and doesn't collapse inward...
    You are removing a lot of mass from the earth.
    Gravity will thus be less and because of that..
    The atmosphere will be less dense.
    Air pressure will be less. we might have trouble breathing.

    Please leave the core where it is.

    A seemingly innocently posed question. But still it it has a vague-i-ness - that should be clarified.

    The earth has several cores and fortunately, even though scientists really like to use words of Latin, Greek, and any old language they can find to name things, in this instance they just have called them simple descriptive names such as inner core, and outer core, as seen here.
    http://www.kids-earth-science.com/earths-core.html

    Not shown, though, ( that site should be updated to reflect current scientific wisdom ), is an inner-inner core inside of the inner core, as conjectured from recent studies.

    Being a planet with 3 cores, much like a computer with a 2 core, 4 core, or more core CPU, if that analogy can be correctly applied and workable, it could be that if one earth core is lost, the other 2 cores may be able to take over from the missing core, working harder at what they do do to make up for the necessary tasks to continue the earth as a functioning unit. How that would turn out for the earth is a dauntless task with the necessary physics hardly understood, if it ever can be understood.

    Then again, perhaps a core-breach is what is being referred to, but realistically that is a whole different can of soup, a subject of which I know absolutely nothing.

    Mass can't just disappear; that violates conservation of energy. So your question doesn't have an answer, because it assumes a scenario that can't happen.
