Though I have done a number of posts about the end of the Mayan long count calendar and all the corresponding media, posts and books about “the end of the world,” I never believed 12-21-12 would be anything more than the winter solstice. Still, I like all the attention that it brought to the calendar and associated Mayan culture.

But this will be my last post on all this before the solstice.

img-maya12David Morrison (Director of SETI’s Carl Sagan Center for the Study of Life in the Universe and NASA Senior Scientist) wrote a good “Doomsday 2012 Fact Sheet” about the scientific take on all this.

It has gone beyond the Maya “prophesy” of the end of the world (which they never really predicted) and people have written about other astronomical threats like a collision with a rogue planet.

The Mayan Calendar(s) is probably the easiest to dismiss. Their record keeping used very long cycles of day counts. But the cycles (one cycle equals 144,000 days or 394 of our years) and when one ends, another cycle begins.

But what about that mysterious planet Nibiru? This hoax about a planet named after some ancient Mesopotamian god came from some fictional books. So, there is no need to worry about something colliding with our little planet this month. We are safe from Planet X, or Nibiru, or Hercubolus, or even Comet Elenin.

There also will not be an alignment of planets this month. As Morrison says, “There is an approximate lining up of the Earth and Sun and the center of our Galaxy in late December, but this happens every year. In any case, planet alignments have no effect on the Earth.”

This is my last post about the 2012 Doomsday before it all ends. By “it” I mean all the hype.

As long as you don’t have a religious take on this, I feel secure that the Earth has been here for more than 4 billion years.

In a few billion years, our Sun will heat up so much that Earth will be uninhabitable.

I’ll let future bloggers worry about that one.



There will be a live broadcast on December 11th (just before you-know-what) called Why the World Will Still Be Here After December 21, 2012
(10:00 PM – 11:00 PM EST) with David Morrison, Ed Krupp and Andrew Fraknoi and they will discuss all these topics. They see this Doomsday meme as having a negative effect on the public perception of science.    Just go to https://plus.google.com/events/cvdkpj271hd9s6its3933fucoc8
