What i am for sure is going to happen is the earth's magnetic field will start oscillating and the waves will induce an altered state of consciousness, likely mass psychosis, not in 2012, but likely by November 2011.
For many- they will experience fear, (a bad trip) and become either dead, demon possessed, or permanently insane; for me I will see it for what it is- a mass hallucination or psychedelic mind state, for others, they will experience a "good trip" and become either enlightened or permanently insane in the physical dimension or leave their bodies outright and their bodies will be animated by an extra-dimensional entity.
SO MUCH FOR DOOMSDAY: Comet Elenin (C/2010 X1), widely known for inaccurate reports of its threat to Earth, appears to be breaking apart. Observations by amateur astronomer Michael Mattiazzo of Castlemaine, Australia show a rapid dimming and elongation of the comet's nucleus akin to that of Comet LINEAR (C/1999 S4), which also disintegrated when it approached the sun in 2000. Comets are fragile objects, so this development while unexpected comes as no surprise. Readers with pertinent images of Elenin are invited to submit them here
