Why not something else?
Have you read “The Cycle of Cosmic Catastrophes”, written by Firestone, West, and Warwick-Smith?
Their book presents evidence concerning a supernova (Geminga, in the Gemini constellation) that occurred 40,000 years ago, and how its blast has effected our planet ever since. The cover is tacky but hey, what matters is inside. The reviews on Amazon.com are consistently positive but beware! This is a science book with lots of graphs and technical data presented.
Also speaking of this, according to some astronomers the Sun is overdue for a massive solar storm which could act like a temporary EMP type burst and cause massive blackouts and even loss of satellites and telecommunications.
Also this book:http://www.amazon.com/Cataclysm-Compelling-Evidence-Cosmic-Catastrophe/dp/1879181428/ref=pd_bbs_sr_1?ie=UTF8&s=books&qid=1215068709&sr=1-1
Supposes the same supernova.
