Since 1996 MSM has been accepting the theory that the core of Earth is crystalline (actually a forest of crystals) as many studies and experiments have supported this idea. The following documentary is a fascinating exploration of this idea: http://topdocumentaryfilms.com/the-core/
The first clue was when scientists found that seismic waves travelling between Earth’s poles move faster than those moving east-west. How could this be explained? As the crystals formed, they received a particular alignment. That alignment, known as anisotropy, makes it easier for waves to travel in one direction than the other. Researchers were able to match up the results that seismologists have been getting on the speed of seismic waves through the core with new laboratory tests with particular kinds of iron crystals.
Professor Kei Hirose recreated the supposed conditions in the Earth's core and produced crystals.
Crystals are conductors or transmitters (electricity, radio waves and so on) and can be magnetised. It seems to me that crystals in the centre of Earth would be transmitting all sorts of information and thus the brain or mind of Earth. (Perhaps magnetism is simply the flow of information?) If this is so, then a magnetic pole shift would be an intelligent process and nothing that we need fear if we are an integral part of this planet?
