We are either alone in the Universe, or we’re not alone. Until formal contact with an extra-terrestrial life-form is established we can only affirm that: Intelligent life exists beyond the planet Earth or it doesn’t.
Nevertheless, we can statistically try and calculate what the possibilities of life existing beyond Earth are, and yet … does it matter? Well, if a positive, progressive energy can be generated by the conclusion, then yes, it does matter.
This week, the media have been latching on to a recently published article from Oxford University’s Future of Humanity Institute that argues the case that statistically we are most probably alone in the Universe.
The article in question, by Sandberg, Drexler and Ord, called “Dissolving the Fermi Paradox” adds very little to arguments already put forward by Ward and Brownlee in their Rare Earth Hypothesis formulated nearly twenty years ago. Despite this fact, the media have picked up on the FHI paper as if it were a totally new discovery, proving that we must be very much alone.
New or not, the Rare Earth Hypotheses argues that the astrophysical, geological, chemical and biological combinations needed to create the cocktail for the evolution of intelligent life is so complex and needs to be so precise that our own existence is a freak stroke of luck, and that the accident we are is so special and fluky that it is very doubtful that is has been repeated anywhere in our Universe.
Yet, should we now assume this hypothesis as definitive? And if we do accept it, can this ‘we are alone’ perspective be beneficial for humanity in any way?
There is an X-Files episode (Redux, the first episode of season 5) in which the hero, Fox Mulder, is in a motel room watching a video of symposium featuring astrophysicist Carl Sagan amongst other, in which the question of the existence of life beyond Earth is being discussed. The actual symposium was held in 1975 and was joint sponsored by NASA and the Boston University.
In this conference, it was argued, in a proclamation by Richard Berendzen, that “the amount of stars in our galaxy alone is so staggeringly large, to the order of 1011 or more; the probability of stars having planetary systems is so high, perhaps half; the probability of those planetary systems might be comparable with our own and that the stars have some kind of ecosphere … suitable for life and it’s not too hot, not too cold … it begins to lead to the sorts of conclusions … that life must exist in the Universe and it must exist quite abundantly.”
Carl Sagan then affirmed that the most optimistic estimates about the number of civilisations there would be in the galaxy is in the order of a million.
Once it had been established unanimously that civilisations had to exist in the Universe, all of the speakers at the symposium expressed the view that contact with an advanced civilisation would have to be positive and enlightening for humanity. With the exception of the scientist and Nobel Prize Winner, George Wald. Wald began his speech with a positive affirmation of life in the Universe, like the others, but ended with a very sobering reflection. The tone of his voice suddenly drops into a melancholy register and he confesses that: “I can conceive of no nightmare as terrifying as establishing such communication with a so-called superior … advanced technology in outer space.” For Wald, such an encounter would be: “The degradation of the human enterprise.” He then went on to describe this enterprise: “One of the greatest of human enterprises is our understanding; something that men have sweated out to the greater dignity and worth of man, and to see the thought that we might attach us by some umbilical cord to some more advanced civilisation, science and technology in outer space, doesn’t thrill me, but just the opposite.”
What Wald is warning us of here, is that an encounter with a superior civilisation would rob ourselves of our purposiveness. And what is implicit in this argument is that humanity could have no meaningful place in any world populated by superior beings, because all our understanding would suddenly be rendered obsolete; and, as such, the human race would itself suddenly become obsolete.
What Wald is describing here, is our reason for being, which is encapsulated in our understanding.
Reflecting on this point, and on our own civilisation at this point in time, we have to conclude that our own lives are very much alienated from this meaningfulness which is our understanding of things, and this displays the tremendous decadence of our system.
But what Wald’s observation also tells us is this: That if we are not alone, it is best to believe that we are alone.
If we are alone it imbues humanity with a tremendous responsibility – the obligation to be sapiens; to understand; to develop the human enterprise toward the fulfilment of knowing; to enjoy the meaningful pursuit of becoming knowledgeable; and, through this understanding, participate in the very Being of the Universe.
The Universe can only really exist in a qualitative way, if there is a conscious entity within that Universe that understands that It does exist. The homo sapiens is the species that knows and reflects on that knowledge. Whether or not we are the only species that knows in this Universe, believing that we are fills us with a powerful, driving purposiveness.
Embedded in this purposiveness is a duty to prolong existence in time and increase the quality of that existence, through progress.
And, in order to do that, we have to overcome the deep, nihilistic decadence that infects our civilisation today.
But again, we run into another paradox, because the human enterprise of understanding necessitates the exploration of the possibility of discovering other intelligent life-forms, even though there is a possibility that we may encounter civilisations so superior to ours that our meaningfulness in the Universe will be totally diminished.
However, perhaps this paradox is false. When we do have the technological capabilities to encounter other civilisations the dilemma would no longer have relevance for we ourselves would be advanced enough to communicate on a partnership level with the other civilisation. Likewise, if Ufologists are right, and we are being visited by extra-terrestrial civilisations already, these civilisations are wise enough to disguise their presence from us, precisely in order not to destroy our purposiveness.
