"US scientists (of NASA) predict total darkness on planet earth for 3 days from Dec 22 2012. It is NOT the end of the world, it is just an alignment of the Universe, where the Sun and the earth will align for the first time. All planets are expected to align in a straight line as a result of which there could be some natural calamities on Earth. The earth will shift from the current third dimension to zero dimension, then shift to the 4th dimension. During this transition, the entire Universe will face a big change, and we will see an entire brand new world. The 3 days blackout is predicted to happen on Dec 22, 23, 24, 2012.... So do good be good live for the present enjoy life."
I have gone through a genuine article published on About.com that confirmed that NASA has not predicted anything as spread in the rumor above. Phrases such as — "total blackout of planet," "alignment of the universe," "shift from the current third dimension to zero dimension," etc. are quite meaningless and nonsense.
"alignment of the universe," - this phrase as quoted in the above false post may be referring to an yearly occurrence of the passing of the sun across the approximate center of our Milky-Way galaxy on Dec. 21, 2012 (the winter solstice in the northern hemisphere). This event as normally occurs in every year doesn't cause any bad impacts or blackouts on earth or in our solar planetary system.
All those false predictions about Doomsday-2012 also revolve around the finding of a giant black hole near the center of our galaxy. People simply predict that this super-massive black hole may end up in swallowing many stars, including our Sun and its planets.
Lot of changes are happening daily to our ever expanding Universe. As such, many of those events are capable of wreaking havoc on the precious life and Eco system on the earth, which is comparatively a small object moving along with supernovas and other jumbo celestial objects in the Universe. So, in fact, any day, even today, can be a doomsday - it need not to be exactly in Dec 2012. In general, everything has a life period - one day, our Sun also will finish burning its atomic fuel and that'll be the natural end of life on earth and the destruction of our Solar system. But, well ahead of that normal death, man's own makings like the pollution and global warming may end up in calling in advance the Doomsday!
So, be a good person and do good things to our mother Earth and its other inhabitants (Live & Let Live), not only on those predicted Doomsday's in Dec 2012, but on every other days also - nobody can foretell when is your doomsday!
