There was an excellent alien civilizations/panspermia article by biochemist Nick Lane in New Scientist. (June last year) He proposes a theory about advanced alien civilizations using their own technology to self-destruct long before they ever get a chance to use it in a way that might give rise to inter-galactic travel.

In other words, any extra-terrestrial* civilization which had a level of technology that could potentially enable them to reach earth, would be more likely to have used that technology in a destructive way long before it ever directed the technology towards getting to ''our neck of the woods''.

* Extra-terrestrial civilization from within this universe.
