Galactic Explosions Inhibit Life

by Robert Matthews at New Scientist

London - January 21, 1999 - Gamma-Ray bursts -- incredibly powerful

An alternate I heard was that cosmic rasdiation and burst are infrequent 
enough that most galactic civilizatinos would start up in quiet low rad 
periods.  Then a blast would kill everyone off planet and crash space, and 
associated ground based, civilization. would be destroyed.  By the time they 
rebuilt the knowledge would be lost, and the blast would have cleared.  
They'ld make the same mistake again.  So we, coming out during a high rad 
point, would be lucky, because we would be prepared.

I'm not totally convinced by this idea, but its interesting.
