Why We'll Never Meet Aliens

The question of why aliens might 'want to come here' is probably fundamentally flawed because we are forming that question from our current (tiny) viewpoint.

      The summary begs several questions, actually.

      One, how can they presume our mental state would be significantly altered by unknown future technology. History would presume to suggest the opposite of what they suggest, actually. Our ingrained drive for exploring the unknown that we had in the days of sailing ships certainly wasn't quashed with the advent of steamships, or then again by airplanes, rocket ships, etc. and the drive for knowledge that we had in the days of stone tablets wasn't quashed by the invention of paper, the printing press, or the internet. If anything, these advances have only increased our drive to know what's out there.

      Two, why would it necessarily take a time span long enough for our universal culture of inquisitiveness to fundamentally shift in order to develop FTL? There is no reason to say it absolutely won't happen before that arbitrary time. We already have theories such as Alcubierrie's suggesting that it isn't necessarily an impossibility, and even if it took 100 years for that theory to be put to practice it's presumptuous to say that drive in our psyche would definitely cease in that short a blip of our history.

      Three, even if technological advancements did reduce our exploratory drive, what is to say that similar advancement would affect an alien mind in the same way? As the answer could be such advancements would affect us the same as us, the opposite of us, or something different entirely in equal probabilities, the question itself is therefore meaningless and all we can do is hope that they have the same drive for inquisitiveness as we do in the first place. Or not. Depending on the kind of Sci Fi you watch/read.

      The premise of the summary is fatally flawed in and of itself. It starts by equating the accessibility and breadth of knowledge to intelligence, and special* intelligence at that. In making the assumption, it posits that a species with greater intelligence would not be interested in the same things that species with lower intelligence would.

      To begin with, knowledge and intelligence are two very different domains. Having greater knowledge is not equivalent to possessing greater intellectual ability, and it is an even further stretch to equate it with special intelligence. Yes, greater intelligence implies greater breadth of knowledge, but this is true only individually. And the relationship between the two is an implication, not an equivalence.

      Secondly, there is nothing indicative in our historical (we know our history, right?) record to even remotely indicate that we as a species has grown more intelligent over time. In fact, I would argue that the distribution of intelligence among the popuplation today is the same as (or even skewed in the negative direction) 500 years ago, 1000 years ago, 5000 years ago, and 10,000 years ago. The local maxima and minima with respect to time are also unchanged. What's changed in the past 500 years that resulted in the exponential progress of our society is a sudden stability in our record-keeping ability, which has lead to us collectively retain more knowledge, and disseminate this knowledge more easily. Essentially, we as a species are not reinventing the wheel all the time, and thus we can spend our time progressing other aspects of our lives.

      Thus as the premise itself is false with regards to the human species, the remainder does not follow. Now, to extrapolate this to supposedly alien beings would be an incredible stretch either way. In fact, I would go as far as to say that attempting to do so would be entering the realm of theology, i.e. unsubstantiated, even ignorant speculation. You might as well say that we will never make contact with aliens because the FSM is keeping them away, and be just about as accurate.

But in the end, I learned where I was at any given time, felt I knew generally where anything was relative to my own position and about how far and how long it would take me to get there. None of this was as fast or efficient as a car GPS with traffic signal reception, of course. So after I moved away from my home area to another state, I finally broke down to get a GPS with traffic and all that. The new location was far more challenging to drive in and missing turns were far more costly in terms of time and frustration -- it was a much older area and so the roads are much more complicated, unpredictable and unforgiving.

    But now that I have been using GPS all this time, I find that my ability to learn my way around and know where I am has diminished significantly. I have grown extremely reliant on GPS navigation.

This energy has to be either generated on-board from stored fuel, harvested from the interstellar medium, or projected over immense distances." -- Wikipedia.

This is about the weight of the 'J' class Apollo Lunar mission payload (LEM, CM, SM, etc). Clearly even the most limited interstellar travel would have an energy cost that is frankly hard to imagine.

The energy costs quoted above indicate that even the most expensive conceivable processes for making things would be cheaper (IE using solar power to perform nuclear reactions to transmute one element into whatever other ones you need and then make whatever you want out of it) than traveling to where you can find something.

      2) As for the "well, things always seem difficult until we do them", I would just like to point out what the 2nd AC said "...if it's at all possible, represents an intellectual and operational barrier an order of magnitude higher than anything mankind has encountered so far." except said AC is wrong in one sense. It isn't AN order of magnitude harder. All the list of things that were listed by JWSmythe above are maybe an order of magnitude, at most, harder than things that were done before them. Going from being able to travel to Mars to being able to travel to Alpha Centauri in something even roughly like the same time frame (IE less than a decades long journey) with a human crew is 12 orders of magnitude harder. Not ONE but TWELVE.

      That's the thing people regularly fail to understand. They've been brought up on a steady diet of space opera/Star Trek where starships woosh around through space like its nothing and a trip to the next star system is like a jaunt to the next highway exit. THAT is surely fantasy. Even if some sort of FTL, or something nearly as good, proved to exist it would perforce have to be incredibly difficult to achieve, else natural phenomena would already exist which recapitulated the necessary phenomena for us to observe. The energies required must be beyond even what is achieved in the presence of billion solar mass black holes and such. No hint of such things is evident.

      Perhaps our Universe was created by a prankster. It certainly seems like the limitations we face are such that the promise of surmounting them must always seem barely out of reach, but I think the prankster did a good job.

    The alien surgeon general recommends not eating pasty white humans from the northwest continent. You can eat all the yellow ones you like from the eastern continent they are much healthier for you. Though you may find yourself hungry again in just a few parsecs.

  22. It's something people don't want to hear. by Myria · · Score: 3, Insightful

    I know it isn't a real popular opinion to hold, but everything I see indicates that interstellar distances are pretty close to uncrossable for physical beings like humans. Frankly I think that is the plain answer to the whole Fermi Paradox that people just don't really want to come to grips with. The gulfs between the stars are so wide that nobody crosses them, EVER.

    I think that the biggest scientific discoveries coming this century will be about what we can't do. We'll progress significantly in applied sciences such as medicine, but in physics, we'll likely prove the impossibility of many things of which we dream.

    Many of us like science fiction stories, but the reality is that they are not dreams of the future - they are merely a modern type of fantasy. We keep dreaming of the stars even when it's impossible. Unless we find a mass relay embedded in Charon.

  23. Re:Neighbors by mcgrew · · Score: 3, Interesting

    You guys are all of the incredibly naive assumption that intelligent aliens will have anything in common with us at all, an example is Terry Bison's excellent short story They're made out of meat. (full text at the link)

    A thousand years more advanced? How about ten million years more advanced? That's mine but another example of how we have no clue whatever (BTW, I'm posting the last chapter tomorrow). Ten million years is a small fraction of the thirteen billion plus the universe has existed.

    The bottom line, though is that we have no idea. There's no proof, or even any indication, that Earth isn't the first planet in the galaxy and maybe even the universe (unlikely as that seems to me) to host life. Mars was once hospitable to life, as our robots have found, but there is no indication it ever started there.

    Great topic for discussion, though. Personally, I think they exist or did exist or will exist, but I really doubt we'll meet them.
