I just wanted to alert readers to this page on the NASA astrobiology website. It’s a Q&A regarding the 2012 hysteria. The page answers the questions that the more conspiratorially-minded think are “gotchas” that really aren’t. Very worthwhile. (Thanks to Guy for the heads up!)
You’ll notice that one of the links the NASA people refer people to is my site debunking Zecharia’ Sitchin’s Nibiru nonsense. Nice to get the love!
