This solar system might well pass through a point that could be deemed as the central plain of the Galaxy. This solar system has never been or will ever be at the center of this galaxy.The Earth does not suddenly wobble or gyrate. This is NOT going to happen in the year 2012. This has all been dealt with before.
If you think this subject has leprosy, thats because its lame and stupid. Go look at some of those previous posts and take in what you have been told.
