Why We'll Never Meet Aliens
iggychaos writes "The idea that aliens will come visit us is fundamentally flawed. Paul Tyma ponders the technology that would be required for such an event and examines how evolution of that technology would preclude any reason to actually make the trip. He writes, 'Twenty years ago if I asked you how many feet were in a mile (and you didn't know) you could go to a library and look it up. Ten years ago, you could go to a computer and google it. Today, you can literally ask your phone. It's not a stretch at all with the advent of wearable computing that coming soon - I can ask you that question and you'll instantly answer. ... How would you change if you had instant brain-level access to all information. How would you change if you were twice as smart as you are now. How about ten times as smart? (Don't answer, truth is, you're not smart enough to know). Now, let's leap ahead and think about what that looks like in 100 years. Or 1000. Or whenever it is you'll think we'd have the technology to travel to another solar system. We'd be a scant remnant of what a human looks like today. ... 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 word 'want' might not apply at all to someone 1000 times smarter than us."
I mean seriously, If i wanted this I would talk to my friend on mushrooms. This is not new in any sense of the word.
"We have no idea how supertechnologically enhanced superscientific aliens would think. THEREFORE, we can be sure that we'll never meet any aliens. Because we don't understand anything of their thought processes. So we can say with certainty they won't find it logical to make the trip."
We aliens are spending tons of money to find really stupid (no intelligence) bacteria on Mars. Why wouldn't some super smart aliens want to find us?
Skimmed TFA - not worth more of my time.
Going back down to that STEM article ..
Duh. If you can't predict then you can't say what they WON'T do.
The reason why aliens would come and visit are numerous. Here are the top 3 that I thought of while reading his poorly thought out article.
1. They are running out of space on their home world, and earth has some nice views, good water, nice temperature. Perfect place to raise a family without bumping into your neighbor (i.e. they don't want to steal just our gold, they want to steal everything)
2. They want to learn about alternate biologies cultures, psychology, etc.
3. Religion. We must spread the word of Latter Day Saints/Allah/etc. etc.
The main problem is the fool thinks the future will be just like the recent past, rather than the distant pass. He assumes our technology will continue to grow dramatically, rather than incrementally.
Right now, the most logical way to do star travel is to increase lifespans to 200+ years and develop a nice cryo-statis type thing.
Which means travel is possible in just about 80 years of technology growth or so, (at least to Alpha Centauri) plus another 100/200 years of cry-sleep transit.
The original article was written by someone that saw way too many bad sci-fi shows and think the most dramatic, silly inventions are likely, and that we/aliens will wait till everything is all settled till we go exploring.

Wrong. It was only like Urkel. The alien has a sweet, heavenly voice... like Urkel! And he appears every Friday night... like Urkel! Now if you'll excuse me, I've got a report to type up on my invisible typewriter.
And we don't need ANY arguments about what such beings would be like in order to understand that there is nothing unique here to want. The Solar System is composed of approximately 99.95% hydrogen and helium. This is basically the same as the composition of the rest of the Universe. While some elements may be slightly more common or concentrated in slightly more convenient forms in one place than another there simply isn't anything particularly unique in one star system that isn't present in another.
Furthermore look at the energetics of interstellar space travel. "Accelerating one ton to one-tenth of the speed of light requires at least 450 PJ or 4.5 ×10^17 J or 125 billion kWh, without factoring in efficiency of the propulsion mechanism. This energy has to be either generated on-board from stored fuel, harvested from the interstellar medium, or projected over immense distances." -- Wikipedia. In 2008 the world used roughly 474×10^18 J, which means the entire power output of the human race for a year would suffice to accelerate one starship of 40 tons to 0.1C, roughly. 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.
So, considering the enormous cost and the high degree of technology required to traverse interstellar space, why bother? Certainly it can never be economical. 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.
Clearly a civilization could in principle literally consume all matter in its vicinity. It is hard to imagine how this would lead to expansion for economic reasons though, there'd never be any hope of getting a return on your investment.
Obviously someone can always invent some new hypothesis as to why, for reasons of alien psychology, aliens would want to travel, but nobody knows squat about alien psychology, so there's really no point in debating it. The very fact that such an undertaking would be VAST in scope, significant even for a Kardeshev level 2 civilization indicates it wouldn't be carried out on some whim, and it seems unlikely that a civilization which spent its energy so profligately on whims would survive long.
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.

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.
I only look human.
