btw, if the poles do reverse, its not going to affect the geology that much.... some ppl think that the earth is going to spin backwards which is impossible
the earth spins at 22,000mph... stopping this inertia is impossible let alone reversing it. The whole reason the earth is spinning, was because of an interstellar collision by a "Twin earth" 4 Billion years ago that eventually formed the moon. This impact started the earth in its spin. Without this, we would not be here.
If it happens, it just means that the magnetic field will reverse.... which can cause major problems for animals which use this magnetic field in their migration path...
Who knows what it would do to satellites (GPS, communications etc).... still its a
theory so yea who knows whats going to happen. The Mayan calendar just shows that is and end of a cycle and a new one will start just after it. Our galaxy and solar system is like a giant clock... the Mayans were experts in reading this information. I'm not too sure anything is going to happen, but I'm sure tons of ppl are going to get very paranoid when we get closer to this time.... still not a bad idea to buy more canned food. :biggrin:
