Magnetic Somersaults - Other possibilities on December 21, 2012:
In the first quarter of 2001, the Sun switched magnetic poles. This occurs every eleven years. Prior to this the Sun's north magnetic pole was at the north rotational pole. Now the Sun's north magnetic pole is at its south pole. Since opposite poles attract, the magnetic poles of the Earth and Sun are now at their most stable.
Just about the time of 2012 Winter Solstice, the Sun's poles will switch back. During this switch there will be a tendency for the Sun's magnetic field to pull the Earth's field with it.
If the Earth's magnetic poles switch, this would put stress on the planet aggravating earthquakes and volcanos, not to mention destruction of the electrical power distribution grid. And, if the switch happens fast enough don't ever expect your computer to work again. But if you have old tube type equipment, keep it. It should survive just fine. It will work if you can find electricity.
What makes 2012 significant is that it coincides with the alignment of the center of the Milky Way galaxy, our sun, earth, and the large planets. If it was not for this fact I would say that 2012 was just another Y2K hoax. But the astronomy makes it believeable.
It looks like this gravitational cosmic tsunami could cause the sun to scorch the earth. That means that the only immediate survivors would be people in the underground cities, caves, and submarines. However, even these people may not survive too long because such an event ( gravitational surges ) might bring on earth quakes and volcanic activity, flooding, and the such. These events might collapse underground cities and caves. Huge tidal floods might flood subways on the eastern seaboard.
However, if just a few did manage to survive. They would not be able to come out of their underground dwellings for some time, because the earth's protective magnetic shield may be gone.
If the upper atmosphere and the earth's atmosphere was able to repair itself say in even a short period of time of one year, the survivors would face a barren world. All surface vegetation and animal life will have been destroyed. The surface of earth might perhaps look like a barren planet. The only possible source of food for those few survivors might be the ocean. Plant life and sea life might survive this event to some small degree. However, there is one problem...more than likely all the plankton will die. They live at the surface of the water and will be destroyed by the radiation.
Plankton is the basic building block of life for many living organisms in the ocean. Plankton is the biggest generator of oxygen on the planet. With plankton gone and the forest gone, what is going to provide and create oxygen for the planet?
It doesn't look good for the few that survive 2012. It may very well be the end of the world. Unless, a greater power comes to rescue us. But are we worth it? Man is a miserable creature that kills and destroys himself and other living things.
