Geophysicist Dr. Josh Keyes (Aaron Eckhart) discovers that an unknown force has caused the earth's inner core to stop rotating. With the planet's magnetic field rapidly deteriorating, our atmosphere literally starts to come apart at the seams with catastrophic consequences. To resolve the crisis, Keyes, along with a team of the world's most gifted scientists, travel into the earth's core in a subterranean craft piloted by "terranauts," Major Rebecca "Beck" Childs (Hilary Swank) and Colonel Robert Iverson (Bruce Greenwood). Their mission: detonate a device that will reactivate the core.
Earth's inner core
Because the inner core is not rigidly connected to the Earth's solid mantle, the possibility that it rotates slightly faster or slower than the rest of Earth has long been entertained. In the 1990s, seismologists made various claims about detecting this kind of super-rotation by observing changes in the characteristics of seismic waves passing through the inner core over several decades, using the aforementioned property that it transmits waves faster in some directions. Estimates of this super-rotation are around one degree of extra rotation per year....
