 sci.astro is a newsgroup devoted to the discussion of the science of
astronomy.  As such its content ranges from the Earth to the farthest
reaches of the Universe.

 However, certain questions tend to appear fairly regularly.  This
document attempts to summarize answers to these questions.

 This document is posted on the first and third Wednesdays of each
month to the newsgroup sci.astro.  It is available via anonymous ftp
from <URL:ftp://rtfm.mit.edu/pub/usenet/news.answers/astronomy/faq/>,
and it is on the World Wide Web at
<URL:http://sciastro.astronomy.net/sci.astro.html> and
<URL:http://www.faqs.org/faqs/astronomy/faq/>.  A partial list of
worldwide mirrors (both ftp and Web) is maintained at
<URL:http://sciastro.astronomy.net/mirrors.html>.  (As a general note,
many other FAQs are also available from
<URL:ftp://rtfm.mit.edu/pub/usenet/news.answers/>.)

This comment and question relates to the ability to eavesdrop on extraterrestrial radiocommunication. This is very nice explanation, and I really appreciate the math. It's also a bit depressing with regard to the possibility of our "ever" being able to detect intelligent life, particularly if the Fermi paradox is addressable by a very short average lifespan for radio-capable technological civilizations before they annihilate themselves or as recently has been suggested more advanced civilization "go radio-silent" due to new cultural or safety measures. If the later are true, and as Hawking has suggested we are seriously in danger of self-annihilation within a few hundred years, it would what we could do in the eavesdropping department if we put all our resources into that. Would massive radiotelescopes on the far side of the moon for example allow us to complete a eavesdropping survey of our entire galaxy (at FM frequencies). It might seem crazy, but I just wonder what would be be big advantages as well...reasonable statistics on the incidence and length of intelligent civilizations, being able to learn about whole new technologies indirectly, and possibly being able to prevent our own demise by learning others mistakes. Maybe it is worth some serious funding and consideration.
