I heard that in 2012 the Sun will align with the center of the Milky Way. Actually I heard that the Sun goes through this "alignment" over over a period of several years and 2012 is near the end of this "alignment".
Is there any reason to think that this "alignment" could effect the Earth in some way?
The only think I could think of is that at the center of a galaxy is a black hole. A black hole can emit a beam of radiation. I wonder if the Sun could cross such a beam during this "alignment", and this could effect the climate on Earth??
