Yes... Welcome Pajamas: I trust this will help. As has been said this solar system does progress. Every 26,000 years or so it bobbles up or down through the galactic plain of this Milky Way Galaxy we are part of. This happens because all of the stars in this part of this Galaxy are progressing around the central mass of this galaxy. We are orbiting the central mass of the milky way. The local group of stars of which the sun is one of are gravitationally bound and do effect each others motion.
The finest metering equipment available might measure a small fluctuation over decades of measurements. You can be absolutely sure that as 2012 comes near those that have the equipment will be very keen to measure any fluctuations of gravitational forces or perceived centripetal effect or just changes in our perception of the position of the stars visible to us. There will be no reversal of magnetic poles or any such other strange erroneous effects other than this forum will once again try to level the histeria... Bang it with a bigger hammer might be a better idea.... I am loosing the will to live....LOl.
