In the early days of computers, when hard drives weighed as much as a piece of furniture, a popular phrase was "Garbage-in, Garbage-out" (GIGO). It meant that computers would unquestioningly process the most nonsensical of input data and produce nonsensical output.
"GIGO" describes the abysmal lack of intelligent thought and critical thinking on the Internet when it comes to all the hysteria about the end of the world coming on December 21, 2012 -- just in time to ruin Christmas.
I'm getting e-mail about this weekly and I expect the nonsense to ratchet up.
This latest installment in decades of flaky astronomical apocalypse predictions is loosely based on the Mayan calendar that marks the end of a 5,126-year era. Apparently the Mayans knew something about the heavens we don't, according to numerous hot-selling 2012 doomsday books on the market. Our multi-billion dollar telescopes, space probes, and 6,000 professional astronomers somehow just can't keep up with the mystic knowledge of an ancient superstitious culture.
With the much-ballyhooed release of the film "2012" opening on November 13, end of world chatter will be the topic from backyard cookouts, to bars, to wine and cheese parties.
I am listing the 10 most popular 2012 end-of-world scenarios and providing a quickie reference guide to use in politely dismissing any friends, relatives, or in-laws whose brains have turned into a pile of GIGO mush after being suckered by the End of Days hype.
The ten top 2012 doomsday scenarios:
1. Changes in the Sun's magnetic field will lead to powerful flares.
So what else is new under the sun? The sun goes though a well-documented 11-year sunspot cycle that is driven by its magnetic field entangling, reforming and flipping polarity. Yes, the peak of the next cycle is in 2012 (or 2013), and some predictions suggest it might be 30 to 50 percent stronger than the last peak.
But experts say it will certainly not be the biggest peak ever recorded.
The bottom line is that no dragon's breath of flame will stretch across 100 million miles of space and blowtorch Earth. The largest solar flare recorded to date, on Nov. 4, 2003, spewed several billions of tons of plasma in Earth's direction. The flare's X-ray radiation that impacted our protective atmosphere had the equivalent radiation of 5,000 suns.
We're still here.
2. The Earth's magnetic field will reverse.
Don't hold you breath. The last field reversal happened nearly 800,000 years ago. Fred Flintstone and our other ancestor cavemen survived. Geological evidence shows that the field has reversed its orientation tens of thousands of times over Earth history. Yet there is no definitive evidence that a magnetic field reversal has ever caused any mass extinction due to increased cosmic ray influx
