Blog：Is the Earth preparing to flip
It is not just the plot for a far-fetched science-fiction disaster movie. Something unexplained really is happening to the Earth’s magnetic field.
In recent years, the field has been behaving in ways not previously seen in the admittedly short time it has been monitored.
Some researchers think it may presage a geomagnetic reversal when the north and south magnetic poles flip.
Such speculation takes place as the science-fiction movie The Core goes on release. In the film, the Earth’s core stops rotating and our planet’s magnetic sheath collapses.
A manned mission is despatched to the centre of the Earth to “jumpstart” the planet.
Scientists admit there are things going on way beneath our feet that they do not understand, and which could have profound consequences for life on the surface.
