Thought I'd dust off the "science" tag and use it loosely.
So, I'm reading this article about the charmingly named asteroid "99942 Apophis" that may or may not hit earth. "Apophis", by the way, is apparently the ancient Egyptian god of darkness and destruction. Those NASA guys are hi-larious!
Anyway, one statement stuck out to me, when discussing the probability of an impact that would wreck havok on most land masses that touch the Pacific Ocean:
On Dec. 27, 2004, the odds of a 2029 impact reached 2.7 percent—a figure that stirred great excitement in the small world of asteroid chasers. Apophis vaulted to an unprecedented rating of 4 on the Torino Impact Hazard Scale, a 10-step, color-coded index of asteroid and comet threat levels.
Okay. So a huge chunk of flying space rock is going to hit the earth, causing over $400 BILLION in damage, and it's only a FOUR on a scale of TEN?!? WTF IS TEN?!?
