The Mayan Calendar is the only clock to count backwards; it is thousands of years old and is more accurate than any similar device created by man. The countdown ends Dec 21, 2012.
The Astrological Age of Pisces (the fish, relating to Jesus, " the fisher of men " ) ends in 2012, giving way to the Age of Aquarius; at this time, the world as we know it will end and a New Age will begin.
In 2012, the Earth passes from Galactic North to Galactic South, crossing a gravitic threshold which will induce magnetic pole-reversal of our planet. Past pole-reversals are recorded in the fossil and geological records; it has happened before, and it is due to happen again. The Earth will literally turn upside down and 99% of all life will perish in tidal waves and earthquakes.
2012 will signal the alignment of Saturn and Jupiter on opposite sides of the Sun, exposing the Earth to massive gravitic forces that may well tear our planet apart or fling it from its orbit.
The planet Eris (AKA as Nibiru) will pass by the Earth in 2012. Most of Eris ' 3500 year elliptical orbit takes it far out beyond Pluto; the atmosphere is frozen and there is no life there, but the gravitic forces of such a large object passing so close to the Earth will cause pole-reversal, bombard the planet with meteors and drag the Earth from its orbit; those who survive will envy the dead.
All these dangers are known to the governments and scientists of the world, but there is only enough space in the bunkers for the absolute elite; the rest of us have effectively been sentenced to death.
