    >As a coda to our recent SETI discussion, two newspaper stories on the
    >subject ran over the weekend. I follow how the media handle this subject
    >because public interest in SETI seems to remain high, and the cultural
    >expectations that show forth in these articles may give us a glimpse of
    >what would happen in the event of an actual detection. Moreover, the Allen
    >Telescope Array has re-focused attention on this quixotic endeavor.

    >Sometimes it seems that we humans give ourselves too much importance in the
    >cosmic scheme of things. After all, what would our little planet have to
    >offer in a galaxy that, as The Age (Melbourne) notes, is made up of 100
    >billion stars (and theres that number again, 100 billion, which reminds me
    >that estimates of our Galaxys stellar population range from this low-ball
    >figure all the way up to Timothy Ferris whopping one trillion). Arent

    >Maybe, but the problem is that we have no way of knowing the answer. If we
    >are the only civilization in the Orion Arm, then were hugely significant.
    >If were one of ten thousand, then were not. Without further evidence, we
    >cant draw any conclusions. The Age notes that even as the Allen Array comes
    >online, the southern hemisphere has been without a SETI search since 2005.
    >In fact, there remain unanalysed data left over from Southern SERENDIP,
    >which began in 1998 at the Parkes Observatory and now, absent government
    >funding, languishes.

    >Weve got stacks of CDs full of data that we just havent had a chance to get
    >through because theres a shortage of time and staff. A couple of hundred
    >thousand dollars wouldnt go astray. That would get our equipment up and
    >free us from our teaching duties to get some analysis done. The thing my
    >colleague and I hate the most is that we started all this and we havent
    >been able to complete the first bit, put it to bed, as it were.

    >It would be useful to resurrect funding at Parkes, given that although the
    >Allen instruments will be able to cover a wide swathe of the Galaxy, a
    >southern skies search opens up even more celestial real estate. The Allen
    >attempt starts out listening to billions of star systems toward the
    >galactic center, but then focuses in on individual nearby stars. A renewed
    >Parkes search wouldnt have that range but would at least complement the
    >ambitious Allen instruments and extend the hunt.

    >Ben Bova, meanwhile, writing in the Naples (FL) Daily News, notes that the
    >oldest stars are doubtless drenched with radiation associated with the
    >black hole at the galactic core. But elsewhere, in the suburbs of the disk,
    >doesnt it just take time to raise up an intelligent species? Maybe, but
    >perhaps theyre extinguished by asteroid and comet collisions or destroy
    >themselves through misuse of their own technology. Bova, a science fiction
    >writer and former editor of Analog, wonders too about just what it is that
    >we mean by intelligence.
    >
    >Or maybe [writes Bova] intelligence is not as inevitable as we assume.
    >After all, Earth existed for almost all of its nearly 5 billion years
    >without an intelligent species. Maybe intelligence is just a special kind
    >of adaptation, not an inexorable end point of evolution. Of all the myriads
    >of species on Earth, only one has produced true intelligence.

    >Giancarlo Genta, who has written wisely and sanely about SETI in his new
    >book Lonely Minds in the Universe (New York: Copernicus, 2007), would add
    >that we dont really know whether intelligence and self-consciousness always
    >co-exist. Just how anthropomorphic do we want to be in our definition of
    >these things? Let me quote from the book:
    >
    >Human beings are both intelligent and self-conscious but, if it may be
    >easier to give a theoretical definition of consciousness than of
    >intelligence, it is much more difficult to tell whether a being is
    >self-conscious or not. Besides, it is not even clear whether consciousness
    >is a discrete characteristic (i.e., a characteristic that either is present
    >or is not), or a continuous one (i.e., one that may exist in different
    >degrees).
    >
    >And later:
    >
    >On Earth, consciousness and intelligence appear to be strictly related to
    >each other. Will it be so when (and if) we discover other intelligent
    >beings?
    >
    >And this:
    >
    >When we say we are looking for extraterrestrial intelligence, are we
    >looking for only intelligent beings, or conscious beings, or beings like
    >ourselves who are both? When we search for extraterrestrial intelligence,
    >are we actually searching for extraterrestrial minds?
    >
    >So many questions, and looming above them all that big Fermi question
    >where are they? I suspect SETI will be a long, hard search. And if it ever
    >does snag an undisputed signal from an extraterrestrial civilization, I
    >would wager that it wont be a directed beacon but an extraneous
    >transmission that well probably never be able to decipher. A huge event in
    >human history, to be sure, but forever enigmatic, reminding us that in
    >terms of communication, the distance between species, as sometimes between
    >individuals, may dwarf our merely human comprehension.
