Why Do We Fear Aliens? Part 1

Monday, August 30th, 2010

by Larry Klaes, space exploration enthusiast, science journalist

Athena’s note: Many readers assumed that I wrote this article, especially those who are familiar with my views on ETI.  I wish I had, but please note the byline.  Though this is superfluous, I should add that I completely agree with Larry.

Part 1

Several months ago, the famous British physicist and cosmologist Stephen Hawking shared his views on extraterrestrial intelligences (ETI) with the intelligent beings of the planet Earth. This was done in no small part as a way to gain publicity for his new television science series, Stephen Hawking’s Universe, video clips of which may be seen here.

Hawking thinks that if biological life evolved elsewhere in the Cosmos as it has here on Earth, then there is a good chance it will have a territorial and predatory nature similar to most creatures on this planet. These behaviors would persist even in species that achieve sentience and technologies that exceed ours.

Sounding very much like the alien invaders from the 1996 science fiction film Independence Day, Hawking’s advanced ETI would roam the galaxy in massive starships that serve as both transportation and home. Having used up the resources of their home world (and presumably the rest of their solar system), Hawking’s ETI would search for suitable worlds to “conquer and colonize,” using them up as well (subduing and/or removing any living native competition in the process) and then moving on to the next set of viable targets.

There are numerous issues with Hawking’s scenario, which even a modest student of science fiction knows goes back over a century, with the invading Martians of H. G. Wells’ classic The War of the Worlds being the most notable of the premise that alien intelligences might treat us the way most human cultures have treated others on Earth for millennia, right up to the present day. The numbers of novels, books, films, television series, and articles that have been made about this subject since Wells’ day would fill a decent size library. So why are Stephen Hawking’s views on this matter receiving so much attention from the media and public?

The most obvious reason is that Hawking is a famous and brilliant scientist, one of the few whom the general populace recognizes with ease, like Albert Einstein, even if they don’t always know or understand his work and ideas. These factors combine to make the public and media think that professionals like Hawking are therefore experts on virtually every subject in existence, including the nature and behavior of hypothetical ETI.

While few would dispute the high intelligence and knowledge of Hawking when it comes to his chosen career fields, the truth is that on the matter of extraterrestrial life he has no deeper insights than any other human on Earth, past or present. Hawking is still subject to his culture, era, and species when it comes to ETI. Even Einstein, to whom Hawking has often been compared, followed the trends of his place and time when it came to aliens. Einstein assumed there were intelligent beings living on Mars and even wrote about an optical method of communicating with the imagined Martians in 1937. Einstein did this despite the fact that by that time most professional astronomers seriously doubted that the Red Planet either had or could support complex, intelligent life forms.

This is not intended to be a putdown of these great thinkers. Instead, it shows that when it comes to predicting the forms and motivations of ETI, after two millennia of contemplation on the subject and just a few decades of actually searching for them, all we really have to go on for solid evidence are the inhabitants of a single planet called Earth and the tantalizing clues slowly popping up across the rest of the Universe.

So why do Hawking and so many others assume a Universe full of predatory life forms, be they amoebae or beings of superior intelligence and technology? Going along the theme that even great scientists are subject to the knowledge limits of their time, culture, and profession, life on this planet has long been viewed and portrayed as one which is in a constant struggle for survival against both the environment and other creatures, including and especially one’s own species. There is of course a great deal of truth to this, as virtually every terrestrial organism spends much of its life fighting for food, living areas, and mates, through either physical force or more stealthy manipulations.

However, in recent decades, it has been recognized that life forms across the board, especially those that exist in societies, are far more altruistic and cooperative than it may seem on the surface. Even humanity, despite its abilities to make war on a globally destructive scale and despoil entire ecosystems, is much more cooperative and conscientious of ourselves and our surroundings than we tend to give ourselves credit for. We have finally begun to recognize and act upon the fact that Earth is not some limitless playground that will tolerate our ancient instinctual needs and behaviors indefinitely. This has brought about our efforts to preserve and protect the remaining resources and biota of Earth – imperfectly, of course, but at least a global response is underway – and we have so far succeeded in avoiding a nuclear war or other similar form of drastic artificial catastrophe, something our military and political leaders considered both survivable and winnable not so very long ago.

With this being the case, would future humanity extend its current instinctual drives in an uncontrolled manner into the rest of the galaxy once we begin expanding our species beyond the boundaries of its home world? Would our children become what Hawking fears about ETI?

While no one can guarantee absolute certainties in either direction with our limited knowledge and experiences in these areas, I will say that I think living in space and on the other worlds of our Sol system, none of which are presently survivable upon without either dwelling inside protective enclosures or being heavily modified (which could take centuries if not millennia to work for the latter case), will force our space-residing descendants to work together for their mutual existence and evolution. The very harsh nature of reality beyond Earth will not tolerate the excesses and foolishness our species has been largely able to get away with for most of its existence.

Of course it is possible that future science could create a form of humanity genetically tailored to occupy just about any corner of the Sol system, on-worlds and off, or they could abandon biology altogether and place the human mind in a mechanical form and/or create a new kind of mind-being called an Artilect.

Granted, these scenarios are not something that will happen next week to be sure, plus they have numerous hurdles to overcome even if they are possible. However, they do illuminate the point that the best kinds of beings to survive and thrive on a cosmic scale are not necessarily the type of humanity that exists on Earth now, or any other form of life suited for one world only. Add to this fact that a spacefaring society would find vast amounts of resources among the planetoids and comet which we know exist throughout the stars and perhaps a species that spends its time marauding inhabited planets makes a bit less sense, if not as enthralling for the entertainment of our species.

Perhaps what Hawking and others fail to completely grasp is that any alien intelligences which do emerge in our galaxy will come from a world that is not a carbon copy of Earth and may in many cases evolve on a Jovian type moon, or a Jovian type world itself, or perhaps in some other kind of environment that current science would not consider to be a place for any kind of life. There is no certainty that even the behaviors or organisms everywhere are literally universal, including the kind that devour their home worlds and then have the ability and will to pack up and do the same thing again and again across the heavens. To be even more specific, the kind of actions and goals that may work for a creature confined to its home world may not be feasible beyond their domain of origin.

The fact that even someone as educated and intelligent as Stephen Hawking should view other societies in the Milky Way galaxy with fear under the presumption that all intelligences evolved in similar ways and will continue to behave in an instinctive manner even if they achieve interstellar travel shows how much of humanity still thinks and lives as if the whole of existence revolves and focuses around our one planet.

Accepting the fact that the vast majority of us have remained Earthbound and will continue to do so for at least a few more generations, our species nevertheless has been intellectually aware for centuries now that we dwell on a rocky planet circling one of hundreds of billions of suns in a vast celestial island. Just as the elements which make up this world are also found throughout the Universe, it is equally possible that biological organisms do universally behave just as Hawking predicts. The question remains, however: do they evolve into beings of higher intelligence who still retain certain instincts or do they eventually move away from them? Or does something completely different happen and is it unique for every species? That will be the focus in Part 2, along with a look at how events might go and why if an ETI ever did attack us and our world.

I Coulda Been a Messiah!

Tuesday, August 10th, 2010

I recently had an exchange with a progressive friend. He had just announced that he had become a fellow of the Institute for Ethics and Emerging Technologies (IEET), a prominent transhumanist venue. Since I had trod that path before him, we inevitably came to the part where I pointed out that transhumanism is composed almost exclusively of white American men — and its upper echelon entirely so (H+ devotees invariably counter that most of their gofers are female and/or ethnic, so there!). Whereupon my friend replied: “Yes, it’s a white boys’ club. As far as I know that’s not because of a policy of exclusion. It’s because primarily white boys think about this stuff.” Which puts him in the same group (and class) as Larry Summers, who declared that women aren’t in the sciences because their brains just aren’t wired for numbiz.

Now, I’d been thinking and talking about issues colonized by transhumanists ever since I became a biologist: genetic engineering, prostheses, organ replacement and regeneration, longevity, brain function – for the simple reason that they are core domains in biology (to say nothing of medicine, society, etc). And ain’t I a woman? A dark ethnic one, at that? So no, Virginia, thinking Bik Thotz is not limited to white boys. But I guess that a thought doesn’t count as big (or even as a thought) until/unless a white boy utters it. Or, as a reviewer for one of my research manuscripts once opined, “If what you report were true, someone would have discovered it.”

The exchange made me realize the fatal error I committed about two decades ago: I neglected to call my thoughts a movement, give it a sonorous name and the glitzy rhetoric to match and register it as a non-profit with me as CEO – or President of the Board, I’m not picky. I could have become the Madame Blavatsky of transhumorism… er, transhumanism.  After all, given what passes as biology in the movement, I could do it half-asleep: I would recycle my Biochem 101 primer decked out in shiny costume jewelry with futuristic terms sprinkled liberally on the word salad. If qualified biologists objected to my prophesications, I would call them bioluddites and sic my devoted groupies on them. And like Pharaoh Hatshepsut, I would attach a beard to my chin and stroke it thoughtfully for more gravitas (and to illustrate postgenderism in action).

Alas, I did not avail myself of the golden opportunity. Instead, I opted to do basic research in the neurobiology of mental retardation and dementia. Not for me the mindmelds of the Humanity Plus Summits (where, this year, a satellite workshop will discuss “whole brain emulation, mind transfer, digital personalities, gradual replacement techniques…” – perhaps with hefty participation by the Syfy channel). Not for me the acolytes who would swoon from interacting with my Second Life babelicious bod. This lack of prescience will preclude me from being a Rupturee. No frolicking in the Matrix Hereafter in a clingy black patent leather outfit.

But I know myself too well. I’d be bored stiff in any place where charlatanism passes for provocative thinking or cutting edge science. Cults are very similar in that you have to actively suppress your brain processes to play along. I told my friend that we should revisit this conversation when his stint at the IEET is done. Unless the Singularity happens first, of course.

Life Is Never Even-Handed

Friday, August 6th, 2010

Chirality (handedness) is intrinsic to life across scales yet surprisingly absent from speculative fiction. The single time I recall a plot point hinging on it is during Mal’s battle with the Operative in Serenity. I have decided to explore this attribute in a series, which I will cross-post here and at Science in My Fiction.

The first article, Southpaws: The Hops in Humanity’s Beer, is up at SiMF today. Versions of it appeared very early on this blog with the title The Left Hand of Light and at HuffPo. I will follow with articles on carbon compounds (aka organic chemistry), biomolecules, brain lateralization… in short, whatever falls under the broad rubric of handedness and pleases my left-handed, left-leaning sensibilities!
