I am interested in verifying the following claim: The most interesting is that the sun will pass through the galactic center (from earth's vantage point) on Dec 21, 2012, which is when the Mayan calendar "ends" (and is also the winter solstice). I'm having a discussion where my argument is that the world won't end in 2012 like many doom predictors claim. Can this claim even be accurately proven/disproven? Also, if there any way to tell when our solar system will line up with the galactic plane? I have to imagine when dealing with such vast distances and taking measurements from the inside, it has to be difficult to pinpoint.
