According to many scientists, especially when it comes to the query, migration and colonization throughout the cosmos by extraterrestrial intelligences, outer space is your ultimate no-man’s-land and quarantine zone. No query; no migration; no colonization. Any intelligent life is pretty much going to be restricted to their very own planetary abode or solar system.
That’s probably true if contemplating intergalactic (between galaxies) space where miles to your nearest galactic neighbour are measured in millions of light years; that’s certainly not true for hash ice o lator interplanetary (between planets) space where miles to your nearest neighbour are measured in light minutes to light hours; now that’s leaving a question mark over the middle ground — interstellar (between stars) where miles to your neighbour are measured in several light years.
But while interplanetary travel is possible in terms of reasonable travel times as witnessed by our own unmanned space probes to the planets and many moons within our solar system, query, vacation, or migration where we’re on the receiving end isn’t likely. We can’t expect any interplanetary visitors, those locals within our solar system, with itchy tentacles needing to explore the local community which we’re a part of, to come calling. The era of the advanced Martian the world, waterways and all, not to mention “The War of the Worlds” scenario, are now gone, restricted to a ‘what if’ history that never eventuated.
Visitors from other galaxies are out of the running as well because as noted above the miles must be surpassed are many orders of magnitude greater relative to short-hop interplanetary trips. It is one thing to frolic in the water several few more program plans of the pool; quite another to frolic in the water across the Atlantic.
With no existing intelligent non-terrestrials of the local kind that can visit us, and extraterrestrials from other galaxies restricted to those galaxies, well that still leaves several thousand of stars in our own galaxy which E. T. might phone if away from home.
Of course telephoning home is going to be a function of your location within our star-stuttered galaxy. Towards the inner aspects of our galaxy (like the inner regions, the CBD, in our cities), stars aren’t as far apart as where we (humans) are out in the suburbs, even perhaps out in the boondocks. It’s cheaper to phone home at local (CBD) distance rates; more expensive when dealing with those boondocks telephone long distance charges.
Regardless, whether you are in our galactic CBD or out in the suburbs or even in the boondocks, I maintain it doesn’t take all that long to get from (say the CBD) to the other (the boondocks).
I can now hear screams of ‘objection, objection’ fot it. Galactic CBD to galactic boondocks; well it’s all obviously excessively far and takes excessively long to get from there (wherever that is, say the galactic CBD) to here (Planet Earth; location: galactic suburbs if not the boondocks). Well, life was not meant to be easy! Seriously, if you think about it a while, any serious arguments fade. If you don’t want to think about it for yourself, then see below!
Unfortunately for the sceptics, fact number 1 is that E. T. doesn’t need any wormhole or theoretical ‘warp drive’ or other ‘Star Trek’ type superluminal velocity techno-babble to explore the galaxy and plainly go where no nonresident is now before. Sure, space is really BIG but it is also early. There are numerous time available to explore and colonize starting a few light years outward at a time. Consolidate, and then expand some more. Repeat as often as required. The time it would take to explore and colonize the Milky Way Galaxy (that is, via interstellar travel) is but a small fraction of the age of that galaxy even if a race of E. T. is the reason never journeyed at more that say 1% to 10% the speed of light. Such velocities, while pretty fast by our current abilities, really should not be beyond the means of a technologically advanced race. I am talking about to cross 100, 000 light years of interstellar space, at 1% the speed of light, requires but 10 million years. Our galaxy is ten thousand yoa. If you doubt this, consult any elementary astronomy text for the relevant miles and amounts and ages and do the computations for yourself if you like.
Regardless of that bit of mathematics, UFO sceptics would still have you believe that interstellar space travel are at best highly improbable, and at worst impossible. Therefore, UFOs cannot represent the technology of a space-faring race of extraterrestrials.
Hogwash! I am unable to believe this old and totally outdated saying is still bandied about since there’s terrestrial equivalents and even a human parallel.
Okay, space is really BIG. Planet earth was actually BIG to human society too many centuries ago, but that didn’t stop our planet being explored from person of polish lineage to person of polish lineage, even if individual travels took many years. And bacteria, pests, birds, and other terrestrial life forms preceded us in exploring and colonizing Planet earth all in pretty quick-smart order.
While it’s proved relatively simple for humans to colonize Planet earth, humans cannot am the stars because we can’t travel fast enough within our short life-spans to make the journey from start to finish, and I assume here that if you start the journey you want to be around to finish the journey.
Now there is no law in neurological science that says an intelligent flesh-and-blood thing must kick-the-bucket after roughly three score and a decade. If you recall from mythology, the cosmic and sky ‘gods’ were (at least from a human perspective) as close to immortal as makes no chances. Quasi-immortality makes interstellar travel quite feasible.
Aliens could use a long natural life expectancy relative to us carbon-based terrestrial bipeds. Again, the purpose must be emphasised that there’s no natural law that bounds intelligent life forms to an existence of just three score and ten terrestrial years.
What if you have an nonresident race with life-spans way, way surpassing our bait? The idiotic premiss by the anti-UFO plainly going skeptics is, in a very anthropological way, that E. T. of necessity must have a life expectancy comparable to that of humans, or is restricted to technologies equivalent to our own 21st Century technologies. E. T. could have, and probably did have, a multi-billion year head begin us since our galaxy was already some 5. 5 thousand yoa before Planet earth (plus Sun and associated solar system) even formed out of interstellar gas, dust and associated debris.
That 21st Century technological equivalency that aliens must have relative to us is more hogwash: any nonresident brains that can visit us will have technologies far beyond our own. There’s a possible likely alternative to a naturally longer expected life relative to humans: what of a bit of the old fashion ancestral engineering to increase life span? Or there’s the possibilities of enhanced bioengineering (part weed; part machine) to accomplish the same goal. What if an exploring race were to take those old stand-by sci-fi concepts of stopped animation or a multi-generation interstellar spaceship? Let’s have a look at those in turn.
Ancestral or other styles of bioengineering could unnaturally extend life-spans by many orders of magnitude. Perhaps flesh-and-blood has morphed into nearly all silicon-and-steel; turning an organic body into something that’s more machine than flesh-and-blood, perhaps akin to the Daleks as featured in “Doctor Who”. Given advances in artificial parts of the body for humans, albeit it cool substitutes or dentures or even mundane enamel fillings, that’s certainly a valid possibility if one extrapolates ahead from today to simply decades to centuries ahead.
But why stop there? Send 100% machines — artificial intelligences (AI) in the form of cybernetic ‘organisms’ or robots or androids or tiny nanotechnology machines. One obviously thinks of Data from “Star Make your way: The next Generation”, or something akin to the original Televesion’s “Battlestar Galactica” Cylons. Think of the savings in not having to provide life support and other life essentials for neurological creatures. We’ve made a start already down this path. There’s nothing different in principle between a Cylon and our Leading 10 & 11; our Voyager 1 & 2 space probes. It’s just that a Cylon is a lot more sophisticated. The day will come when our Pioneers and Voyagers will morph into something approaching a Cylon, or any one of multi-dozens of similar ‘beings’ in the sci-fi literature. Since AI is almost immortal (relative to flesh-and-blood), that takes care of travel time arguments, and the possible environments fit for relative easy query (colonization? ) are expanded greatly. Artificial brains can plainly go where no man (flesh-and-blood) is now, or could go.
There’s the standard sci-fi scenarios of the multi-generation starship or hibernation that passes the time away without much additional aging. Even if E. T. has a neurological life expectancy roughly equivalent to our own, advanced extraterrestrials may have enhanced various hibernation techniques. Put your spaceship automatically and sleep the long journey away. That sort of scenario has been a staple of science fiction for generations, for example think of the films “Alien” or “2001: A location Odyssey” or the original “Star Trek” TV episode that featured Khan.
There’s another sci-fi staple that could get E. T. from there to here. That way is via the old sci-fi saying, the multi-generation interstellar spaceship. While I find myself that’s an unlikely concept, for query, it might not be quite so far out if the objective is interstellar colonization.
