The quick answer to this is “no”. However, Dr. Steven Novella, MD, an academic neurologist and the host of Skeptic’s Guide to the Universe, examines this question closer in last week’s episode of The Skeptic’s Guide to the Universe (timemark 26:30). I thought it was pretty interesting.
Also on this episode you will listen to Dr. Seth Shostak, a SETI (Search for Extraterrestrial Intelligence) Institute Senior Astronomer. In this interview you will hear the latest from the SETI project (did you know that SETI’s “searching power/technology” has doubled every year for the last seventeen years?). If you haven’t subscribed to SGttU yet, I highly recommend doing so now. It is the best podcast on Skepticism out there. (You may download this episode here)
