Some stuff about aliens


I’ve met many aliens during my brief time on Earth.  None to my knowledge in reality, but many through millions of words and fictional worlds I’ve avidly consumed over the years.  These have no doubt informed the way I’ve created aliens over the years.

It is hard to avoid cliché when creating an alien. In a gravity different to Earth, they could be taller or shorter; their atmosphere may be completely different; they may have completely different food sources and will no doubt support different microbiomes which may have in turn channelled their features.  Carbon-based lifeforms are mostly likely according to the higher echelons of SETI, but that doesn’t mean to say other forms are unlikely.  Many authors use silicon as the predominant building block, although Silicon-based compounds are inherently more unstable, and other elements even more so.  In any case, it seems that when considering this that they will be like us in any shape or form. But is this strictly true?

We have seen so called biological or physical attractors in evolution on our planet – look at how the octopus eye and human eye, have developed independently along completely different evolutionary pathways – so-called convergent evolution.  Are humanoids clichés or an inevitability?  I tend to think the latter.  Although this isn’t to say there won’t be other differences.  Although, this is probably a presumption based on a carbon-based lifeform, which has evolved in a similar ‘Goldilocks’ zone to Earth.  This could explain why we see so many humanoids in SF, for example in series like Banks’ Culture.

So should aliens be feared or should we be grateful for their presence?  If aliens do ever make contact, then they would surely be of at least a technological parallel to ours, if not more advanced.  There is a good chance they may be able to help us out, let us piggy back off some of their technologies, such as the McAuley’s Jackaroo.  This doesn’t mean to say they won’t want something from us, whether it be elements of our culture, or at least, a calm, focused approach to their presence.  Humanity doesn’t have a great record when it comes to dealing with members of our own species, let alone others.  Could this be one of the reasons why they haven’t yet contacted us?

This brings me to Fermi’s paradox, the contradiction between the thought that given the four hundred billion stars out there in our galaxy, there is a high probability some must harbour civilisation, so why don’t we know about them?  Is there an alien race out there, truly to be feared, like Reynolds’ Inhibitors, which extinguish everything as soon as it starts propagating beyond certain pre-defined limits?  Have their civilisations blossomed and died already on the vast canvas that is space and time, such as those which created the cylinder of Rama?  Is it because we inhabit a part of the Milky Way lacking enough dark matter for subspace transport?  Or are we simply too immature as a species, too intolerant and irrational to intelligently deal with them?

Is it highly likely that aliens are out there, somewhere, or maybe even moving amongst us.  Whether they will be able to help us or thwart us as a species is likely to depend on how we react to their presence.  But until they make themselves known to us, we have to rely on conjecture, and sometimes fantasy.  In the meantime, they can make good stories and help explain elements of ourselves, preparing us for that moment which will shake us a species, but perhaps bring out the best in us.
