Astrobiology
and the Search for Meaning: An African boys perspective

The Astrobiology Newsletter [January 2006]
A Moral Dilemma
I spent most of my life in Southern Africa. Like a grain of Kalahari
sand carried in the Okavango River that suddenly finds itself
quite unexpectedly in the fertile Okavango Delta, the river
of life somehow carried me to UWs Astrobiology Program where
I found myself surrounded not by Gemsbok and Fish Eagles but rather
by some of the best astrobiological thinkers (and, after three years
of national conferences, I confidently count our graduate students
amongst these) on the planet.
Memories of my Third World childhood frequently stir me to justify
my luxurious existence as a researcher into Earths deep past.
It is my contention that, within an age that has been aptly coined
the anthropocene, the allocation of resources towards
the pursuit of NASA-scale scientific goals requires critical evaluation.
The resource-base with which our planet is endowed is limited, a
fact that should now be becoming increasingly clear to even the
most ardent of industrialists. Indeed, it is arguably exactly the
scientists -even more than many of their planetary co-inhabitants-
who should be expected to be particularly self-critical in this
context, working as they commonly do at the interface between humanity
and the natural world. Do we go to Mars, or heed the near-apocalyptical
outcries of many environmentalists and invest instead in monitoring
our planets bio-, geo- and atmosphere through Earth-observation
satellite technology?
And then theres the fact that someone needs to feed scientists
such as myself. In return, we can rarely offer more than a vague
commitment to the taxpaying public to increase the information content
of the universe, largely through the publication of increasingly
specialized articles in increasingly unreadable scientific journals.
In Defense of Astrobiology
Peoples of all cultures and times have derived Meaning from pondering
the questions that we astrobiologists get paid to answer. Meaning,
I contend, is largely a matter of timescale selection. We humans
are evolutionarily conditioned to contextualize our experiences
within the meagre timescale of a couple of generations at most.
In much of the Western world, the dominant trend towards forever
increasing individualism further shrinks this window of reality
to the pitiful lifespan of our own consciousness. Astrobiology certainly
provides some refreshing temporal and spatial distance from this.
What is to become of Meaning in the face of an expanding infernal
Sun overrunning Earths orbit about 4 billion years from now?
And is Meaning itself somehow slated to escape the ultimate universe-scale
heat-death necessitated by the Second Law of Thermodynamics? With
these upcoming events in mind, can a human-catalysed mass-extinction
objectively be regarded as A Big Deal?
With these thoughts in mind, I return to the microscope on my desk.
Looking through the eyepieces, the dark mass of 3.8-billion year
old graphitized organic matter still sits quietly, unmoved, waiting.
