Written by E. C. Krupp – Director of Griffith Observatory in Los Angeles - this article points out that we don’t have to be worried about any doomsday coming at a known date, and points out some interesting facts, well sustained with scientific arguments.
I highly encourage you to read the article, it is structured to make the average reader understood why the entire story related to 2012 doomsday is highly overrated.
I liked especially the last phrase, and indeed it might come soon the end of the world – not due to a catastrophic event – but because of our own paranoia.
