We survived Y2K back in 2000, and now, 12 years later, our existence faces another doomsday catastrophe -- the end of the Mayan Calendar! According to some superstitious believers, tomorrow, December 21st, marks the end of the world as
predicted by the Mayans over 5,000 years ago. Despite lack of evidence for this prophecy, and as disproved this week by NASA, scenarios suggested for the end of the world include the arrival of the next solar maximum, an interaction between Earth and the black hole at the center of the galaxy, the alignment of the planets and Earth's collision with a planet called "Nibiru".
