Report Copyright Violation | Scientists find oddly behaving 'inner-inner core' at Earth's center [ link to www.cnet.com] Though the seismic waves from earthquakes are best known for their destructive abilities, in the hands of geologists, they can be powerful tools of discovery. A research team at the University of Illinois (UI) has just used the rumbles from quakes to more closely examine the core of our planet, and what they found there was quite a surprise. It seems our Earth's core has another core that measures about half the diameter of the original core. What demarcates this "inner-inner core" is that the iron crystals it contains are oriented on an east-west axis, unlike the iron crystals in the "outer-inner core" which organize along a north-south axis. |

Report Copyright Violation | Re: Scientists find oddly behaving 'inner-inner core' at Earth's center Interesting. But if they just discovered this inner-inner core, How do they know it's behaving oddly?
Maybe that's how it's been behaving for a billion years. |

Report Copyright Violation | Re: Scientists find oddly behaving 'inner-inner core' at Earth's center The way the crystals align within the cores may be a cause or effect of magnetic polar shifts, at least that's what I thought when I came across this info. Noblesse Oblige |

Quoting: Anonymous Coward 57857441 they're gonna nuke the inner core to stop the magnetic flip-flop. (i seen the movie)  |
