Anti- Doomsday Bombs
Interesting story from NBC News about efforts to develop nuclear weapons for stopping asteroids from smashing into the earth. They say they've identified 90% of the larger asteroids and they aren't a threat. Scary subject.
What about the other 10%? Keep in mind that one meteor accompanying that last close asteroid fly- by wasn't detected until it blew up in the sky over Russia.
Update: Oh, NO! Here's an asteroid that could hit us in 2036...maybe.
Another fun, albeit scary, story found for me by the Rational Review News Digest.
