...first time i've heard of 2012 its not the first time i've heard of 2012 being a year where the world supposedly ends, i know that the center of the galaxy lines up with something and its all weird but why does that mean the end of the world can someone break it down for me to why this certain alignment is supposed to mean doom

its rarely happend i think the last time it happened was 13000 years ago or something haha
