Well, they say there is a blackhole in the middle of the Milky Way galaxy, but they also say that a moment that happens ever 25,800 years where the earth goes to the center of the galaxy, and that's in 2012!!!!
probably nonsense, but still, the scientests whouldn't lie... right? but there is also a massive solar storm predicted, and there is a hole in earth's shield from solar flares. ALSO there are alot of predictions of WWIII, and the mayan calender ends in 2012... am I really thinking this stuff is real?
The Earth's Shield from Magnetic Flares is the Earth's magnetic Field, and there isn't any holes in it that I am aware of, so no real fear there, although a really strong one could penetrate a bit...
Also, the Earth Orbit's the Galactic Core, and thus goes around the black hole, and not through, and we are about 2/3 of the way out, so that is a long way, no fears there...
