Are We Alone?
The chances are very high that you will encounter
another intelligent life-form in the course of your life and when you do it may
come as a big surprise. When, for instance, did you last visit the zoo? Remember
those chimpanzees - very smart. And how about those dolphins at the marine
aquarium? Brilliant! And that cat of yours is probably smarter than you think -
but your dog will never admit it. Finally that grey parrot your Uncle Ned has
may actually know what its talking about! Ultimately by paying attention to
signs of intelligence on Earth, we may also come to recognize signs of
intelligence amongst the stars.
Are we alone?
Given the immensity of the Cosmos, a mathematical
impossibility. Will we ever come to know we are not alone? That's a tougher
question. But should first contact occur today we could be in for a shock1.
So right now may be a good time to prepare. And perhaps the best way to prepare
is to imagine the possibility...
Numerous psychological studies have shown that "imagining a thing" makes us more
receptive to the possibility. In fact many of the great breakthroughs in
scientific thought came about as a result of the proper use of the creative
imagination. Sir Isaac Newton saw the motions of all moons and planets
everywhere in the simple fall of a ripe apple from the boughs of a tree. Albert
Einstein perceived the relativity of all time and space while contemplating the
accelerated motion of a trolley car moving away from the face of a public
clocktower. We human beings might want to take a few moments and think about how
we will respond should ET make an appearence in our small corner of the cosmos.
So, take a moment and relax. (Yes it's true, deep breathing does help!) Imagine
a universe populated with many and diverse forms of intelligent life. Extend
yourself through time and space toward distant systems of suns and planets. See
simple organisms thrilling to the rhythms of light and matter working in harmony
to develop ever more sophisticated life-forms. Follow the earliest interstellar
craft as they move tirelessly from system to system toward some distant
beckoning beacon of promise. Surf beams of radiant energy flung like arrows from
far away lighthouses upon the Ocean of Space.
Someday such imaginings may be confirmed by rock solid science - perhaps SETI
will detect an indisputable signal from beyond, or "Michael Rennie" emerges as
an emissary from the Galactic Federation of Planetary Systems trailed by Gort -
the Wonder Robot.
Given the likelihood that such space-faring or highly communicative
intelligences exist, and given all the billions of years for off-world
intelligence to develop the means to travel and communicate, plus our own recent
efforts to find them out, why don't we know already?
One, and possibly the very best answer is "We aren't ready."
The human imagination also has its down-side: Imagine the initial shock and
ridicule as we humans attempt to upright a world overturned by what for many
will be an impossible event. Consider also how governments and institutions,
groups and individuals, have responded to similar reports in the past. Remember
"Mars-rock"? Do we hear much of it now? And what about pilot Hap Arnold's
"flying saucer" report. Can we really say that we have taken clear-headed,
scientific looks at such things? Or is our normal response one of incredulity
and ridicule? Hmmmm...
To know is to see truth wherever it may be found. No, we're not saying that
UFO's have visited the Earth. What we are saying is that our response to those
who make such claims is often one of ridicule and disrespect. Is it not possible
that compassion and open-mindedness would be more appropriate?
So let's seek truth where it can be found - right here on Earth. We can start by
looking for unsuspected signs of intelligence around us2.
Let's take a clear-eyed look at our animal friends by setting aside prejudices
concerning their intelligence. Those goldfish in the aquarium can be
surprisingly sensitive about things. Walk near the tank during the day and they
ignore you. Come feeding time, and you are the most interesting thing in the
world to them.
To be sure we are very unlikely to learn that the universe is suffused with
intelligence until we get past our own anthrocentrism. It took a lot of hard
work (and self-sacrifice) by Copernicus, Kepler, and Galileo just to get western
society to finally step "up to the edge" and see that the Blue Planet is most
definitely not flat nor does it act as the axis around which all things
celestial swing.
And even with the signs of intelligence abounding on our homeworld today we
persist in thinking that all creatures exist for us, our amusement, our
purposes. Under such conditions can we possibly appreciate how truly intelligent
they are? And to be more germane, do we really think ET might want to come out
and play with us under such circumstances?
Today we don't seem to be ready to accept anything other than the myth of being
alone. Yes, one way to tell this does have to do with how we relate to other
creatures on the Blue Planet, but there are other reasons to doubt our readiness
as well. Consider our political institutions; Why is it that our leaders and
their associates spend so much time "down-playing" the truth of things,
presenting specious arguments to motivate behavior, or putting controversial
issues into the spin cycle? Is it because of hidden political or economic
agendas? Or possibly because they don't believe we can handle reality3?
Meanwhile high overhead, ET approaches the Earth - third stone from the Sun -
and initiates a scan of the EM spectrum. Newscasts portray crisis after crisis,
violence, conflict, bloodshed, environmental degradation. How would you - an
intelligent being from elsewhere respond?
Personally, I'd activate the cloaking device.
ET is no dummy - he/she/it is after all an intelligent life-form possessed of
advanced technology. One scan of Earth's broadcast media and ET soon comes to
see that this is not a place to be trifled with: The natives are restless.
Emotion overrules reason. Reaction upstages proaction. Nations practice
deception and ill-will in relationships - internal and external. Angry voices
shout each other down - not just on the streets but in the houses of governance
as well. We are not a happy bunch.
And yet the future remains always a bright star of possibility. Hope springs
eternal in ET's breast (or left antibular thorax as the case may be...)
ET of course, has seen such things before. Countless worlds of lesser and
greater advancement have been encountered. Before ET learned the wisdom of
keeping a safe distance, he-she-it actually tried to help a few troubled worlds
such as our own. In the end ET may have had to overcome shock, ignorance, even
bloody insurgencies. Costs were great, rewards few. Now ET waits - waits for us
to pass certain tests - tests defined in some intragalactic protocol: "The Prime
Directive".
So the hailing frequencies are locked down. ET goes stealth. "Subspace" signals
are transmitted to ET Central: "Earthlings are still at it. Planet approaching
ecological crisis. Species dying off. The few have much, many have little.
Schedule re-visit next solar maximum. Report over and out."
Today our instruments can peer back to the very threshold of the Big Bang -
nearly 13.7 million lightyears distant in time and space, millions and millions
of galaxies, billions and billions of Suns. Who knows how many planets - many
equal to or superior to our own in fecundity and arability. Some populated as
yet only by single-cell organisms. Others by beings possessed of no organic form
whatsoever. It doesn't even take the imagination to see the possibility anymore.
Those of us interested in astronomy also read and watch science fiction. All the
heavy lifting has been done for us. Fantastic lifeforms dwell in fabulous
environs undergoing incredible adventures: Star Trek, Star Wars, Babylon Five -
you name it - we've seen it. And yes, many of us believe in our hearts - but
even so, we want to know.
Even now we scan the heavens seeking proof. The SETI project is bringing its
array of parallel narrow-band scanning recievers on line. We hope against hope
that some not-too-circumspect intelligence is out there broadcasting narrowband
signals intentionally (or not) seeking to conclusively demonstrate their
presence in our universe.
Will SETI find them out? And if so, how will we respond to the reality?
It is possible to uncover intelligence in this way, but intelligent life-forms
not only learn from experience but in advance of experience as well. Do we here
on Earth choose to project our presence intentionally into the interstellar
medium4?
No - that particular notion has already been discarded and perhaps wisely so. We
know what we are like - others could be worse!
Psychology plays a big role in choices made by intelligent creatures. When they
don't trust others, they "down-play" the truth or offer specious arguments. When
they make mistakes, they put things in the "spin cycle". When they see other
intelligences doing these kinds of things with great regularity they know that
contact is to be avoided. Perhaps this is at essence in first contact protocol.
Until truth is welcomed - even at the expense of notions held dear - a world is
not ready. Otherwise the cost of engagement is too high, benefits too low, and
outcomes too unpredictable - or worse - dangerous.
But we may detect extraterrestial intelligence in other ways. It's a solid
assumption that all advancing technologies pass through a broadband em broadcast
phase. During such an era civilizations "leak" evidence of their existence.
Unfortunately, even our largest radio telescope would be hard pressed to detect
broadband transmissions - such as Earth's - from as close as the Alpha Centauri
system. Meanwhile the window on em broadcast may even be closing here on earth.
How many of us watch television programs delivered by antenna today? Less than a
half-century ago every house had its own "rabbit ears". One-hundred years from
now we may be EM mute...
We might also intercept a signal in transit between two worlds. Such an event
would be serendipitous - luck would play a huge role. First we would have to be
more or less line of sight. Why? Because the tighter such a signal is foused the
further it travels without attenuation. Although laser (and maser) transmissions
do diffract over great distances, we would still need to be well-placed to pick
one up. Meanwhile such signals may not necessarily be narrow band in frequency.
Why? Because phase-modulated transmission may be the most efficient way to
transmit pictures, sounds, and data across space5.
Despite all these barriers to revelation what practical steps can we now take to
prepare for some future "first contact"?
Assisted by writers of science fiction and purveyors of motion pictures, we've
already made a start by imagining the possibility. Animal behaviorists have
helped prepare us by investigating various types and degrees of intelligence in
the natural world. Psychologists and socioligists have done the same thing in
the realms of our own species.
Meanwhile on an individual basis we can all learn to pay more attention to
intelligence as seen within our families, among friends, associates - and even
strangers. (Perhaps especially strangers.) All this makes us more aware of what
intelligence is and how it is communicated.
On the broadest possible levels we must all further our ability to welcome and
speak truth - despite any pain it may leave in its wake.
Having done our own personal work, "homeworld work" can go forward. Collectively
we can work together to expunge the seeds and uproot the weeds of war on the
planet. Although this means holstering our weapons, it also means overcoming a
persistent propensity toward propaganda, religious strife, scientific
contention, and undue corporate economic advantage.
And of great importance at this time is the need to be more supportive of other
homeworld species - irrespective of intelligence. Ecology teaches us that every
creature plays an important role in Earth's biosphere. Perhaps it should become
a matter of human education, demographical planning, economics, and political
activity to ensure that this particular insight truly guides our choices and
behavior. After all so long as we remain exploitative of lesser species no truly
intelligent extraterrerestial species is likely to have much to do with us.
Scarier still, if there are any "bad boys" out there, they could easily
rationalize "taking over the joint".
So let's say we clean up our act. What happens next?
Isn't that enough? To live in a world where truth multiplies, nature is
respected, intelligence is recognized, and peace reigns supreme is actually
quite appealing in itself - for most intelligences worthy of interstellar
relations.
But this article is not about social transformation per se - it's about the very
real possibility of first contact - something that could transpire even before
our children take a leading role in the unfolding story of human history.
Are we ready to get ready?
If intelligence can germinate here, it can flower elsewhere. Why, of course,
it's all so - "self-evident!"
1 The 1997 hit movie "Contact" (based on a novel by
Carl Sagan) portrayed the many and varied ways in which human beings responded
to scientific proof of the existence of advanced extraterrestrial intelligence.
2 According to
a BBC News
article a captive African grey parrot named N'kisi has a vocabulary of
almost one thousand words, shows evidence of a sense of humour, and devises new
words and concocts phrases as needed.
3 Irrespective of its overall merits, US efforts to topple an
Iraqi dictatorship were found to be based on overstated evidence. (See
Conclusions of Senate's Iraq
report) Such misuses of information often occur when a government is
unable to speak plainly to its citizens concerning matters of importance.
4 In an article published by the title
Quantum Communication Between the Stars? SETI Institute member Seth
Shostak recalls the heated response of England's Astronomer Royal to the ad hoc
messaging of M13 during a 1974 ceremonial at the Arecibo radio telescope in
Puerto Rico.
5 The narrower the frequency used to transmit data through space
the higher the signal-to-noise ratio. The most efficient mode of such
transmission is to digitally switch a carrier frequency "on and off". Such
serial modes of transmission however, are very slow at transfering large amounts
of data through space in short amounts of time. Such signals are however very
useful for saying things like "look at me I am here!".
