Okay.

This is a side-view of our galaxy, the milky way (or at least an artistic representation of it) :



As you can see, it is not perfectly flat, it has a certain "height". Now, you can't really see it like this, but the bright line in the middle of the picture is formed of billions of stars. One of these stars is the sun, our sun.

Every star revolves around the center of the galaxy, but they also change their relative height, over time. What will happen around december 23rd 2012 is that the sun, and our whole solar system, will cross the middle of the milky way. There is no "up" and "down" in space, but if you consider that we are above the white stripe on the above picture as of now, in 2012 we will cross below it.

Now of course, you wonder "but what will that actually do to us?".

Short answer : ABSOLUTELY NOTHING. So stop freaking out already :x
