Question

When most of the planets align in 2012 and planet earth is in the center of the milky way,what will the effects of this be on planet earth? could it cause a pole shift,if so what could we expect.

There is no planet alignment in 2012 or any other time in the next several decades. As to the Earth being in the center of the Milky Way, I don't know what this phrase means, If you are referring to the Milky Way Galaxy, we are rather far toward the edge of this spiral galaxy, some 30,000 light years from the center. Concerning a polar shift, I also don't know what this means. If it means some sudden change in the position of the pole (that is, the rotation axis of the Earth), then that is impossible. There is no point in speculating about the consequences of something that has never happened and never will. Before geologists discovered the role of plate tectonics (about 60 years ago), there was some speculation that a polar shift was involved in transforming the Antarctic, for example, from a warm to a cold climate, but now we know it was the Antarctic continent that moved, not the rotation pole. The bottom line is that there is no possibility of a "polar shift" and no danger associated with one.
