The "Great Filter"

Posted by Mac Tonnies, May 13, 2008 at 10:00 AM by Mac Tonnies

Oxford philosopher Nick Bostrom recently wrote an article for "Technology Review" championing the concept of a "Great Filter"--a sort of existential black hole assumed to either preclude the emergence of complex life or else destroy advanced civilizations (thus SETI's failure to detect intelligent signals). Bostrom posits that we should hope to find our own solar system devoid of primitive life, since such a discovery would indicate that the Great Filter lies in our future instead of our past, thereby effectively condemning humanity to extinction before we're able to announce our presence to the galaxy (assuming we'd want to).

While I'm agnostic as to the ultimate nature of UFOs, I'm comfortable asserting that the phenomenon is both physically real and under intelligent control. Too brash a deductive leap? Given the available evidence, I don't think so. Indeed, my position isn't nearly as hard-set as that of most speculators among the loosely knit UFO "community." So what are we dealing with? Does intelligence imply an extraterrestrial origin? And is my agnosticism simply a mask with which to deter meandering conspiracy theories and hoary notions of human-ET treaties?

10 Must-See "First Contact" Movies

Posted by Mac Tonnies, May 01, 2008 at 12:00 PM by Mac Tonnies

After posting a list of 10 favorite novels about extraterrestrial contact, I suppose I'm obligated to comment on movies that reflect upon the search for alien intelligence. This list is by no means intended to be exhaustive or even particularly representative; if you have any additions, feel free to mention them in the comments section.
