Here are some scenarios of what the woowoos claim will happen in 2012. Some of these are different to the ones we have seen so far, so I thought I would post them:
Two of them are about the sun exploding (with nasa link included, that shows study of the sun, not woo but they used it anyway). the other about a quasar in the center of our galaxy that could explode an irradiate gamma rays and ultraviolet rays, killing us all of course. Other ones cover UFos, hyperspatial breakthrough, something called a 'planetesimal impact" and so on.
the galactic alligment cannot cause the sun to explode and regardless to the claims, I don't think the sun is blowing up anytime soon.
But is there some truth about the quasar? can it be lethal? and what is the planetesimal impact? I have found no info on it.
