New explanation postulated for Fermi paradox
April 12, 2011 by Bob Yirka
(PhysOrg.com) -- Enrico Fermi, the famous Italian physicist, once asked the question; if intelligent life has come to exist many times in our galaxy, why is there no sign of it? Its a clearly valid point, when you consider the number of planets and solar systems that exist out there. If there are other intelligent beings out there somewhere, how come they havent responded to our messages?
Adrian Kent, of the Perimeter Institute in Waterloo, Canada has published a paper in arXiv, somewhat humorously titled, "Too Dammed Quiet?" where he suggests the reason we havent heard from other life forms out there, is because maybe they are keeping quiet on purpose, to protect themselves from others that might hear their noise and come to investigate, and perhaps cause them harm.
Kent takes the idea of Darwins survival of the fittest concept to a galactic level, in that he believes its possible that there are only so many habitual planets and if so, that would mean scarce resources, which would mean only the smartest, strongest, or most careful would survive; which would leave at least some of the aliens out there keeping a lid on things to assure their own survival; sort of like how certain species of birds on this planet freeze to avoid being noticed by predators.
But, if what Kent has to say is true, that begs even more questions, such as, who are they hiding from, and why havent we heard anything from those pesky predators?
His paper raises even more difficult questions, which of course we have no answers to, such as is it possible that the vast expanse of the universe is so great that the laws of physics will forever prevent any life forms that do crop up, from ever being able to contact one another? Or, is it conceivable, that the events that led to our existence are so rare that there really isnt anyone else out there?
Kents paper has no doubt some added credence due to his support of Stephen Hawkings parallel suggestion in Into the Universe, the Discovery Channel documentary that made headlines all over the world last year; but as with all hypothetical suppositions, ultimately, its all, as Kent himself reminds us, pure speculation; at least until we hear otherwise from someone out there who can settle the matter for us, once and for all.

It has taken, what, in excess of 13 billion years for the human species to get to a point where we could actually listen out for any racket our neighbours may be making. We've had the ability to listen for - let's be generous and say - 150 years.
So, imagine that some technological race, emitting some form of human-detectable signal, has evolved in a solar system some 150 million light years distant. For us to 'hear' them, they would have had to have been emitting this detectable signal almost exactly 150 million years ago, with a 150-year window. And be emitting from a direction we've listened to. And be emitting in a form we've paid attention to. And, not be obscured by any intervening source of interference...
It's never struck me as a paradox at all, really... Thoughts?

1. Perhaps there was a "staggering" of intelligent life in our galaxy, i.e. they went extinct much like life has been nearly wiped out several times on the Earth throughout its history.
2. The galaxy is very large, to date even our civilizations messages have only travelled about 120 light years in all directions, this is only about 1.2e-3% of the diameter of the milky way.
3. We have been listening for messages from space for even less time than we have been broadcasting radio signals.
The list continues for a while, there are countless scenarios that are all reasonable. There is no paradox, this is a pointless article, and a pointless discussion as everything one can currently say is pure speculation. There are too many what-if's and maybe's.

2. Distance/time is vast.
3. The communication window is small. We produce a lot less EM noise than 50 years ago, perhaps technology moves on, away from EM broadcast?
4. What is the usual lifespan of an technological civilization? Lots of sharp edges there. A short lifespan further limits the communication window.
5. chemisty/biology - perhaps bioforms cannot live off the planet of origin? Our view of life is very deterministic, what if we are much more a part of a web of life than we realize and cannot survive for long outside of the biosphere?

Like many important questions, the question of how far away would our radio telescopes be able to detect a species that broadcasts as we do has never been asked or answered to my knowledge. It could also be that we can't detect plain radio broadcasts very far away even with radio telescopes. Many species might be broadcasting for local communication but not for reception from great distances.

In such a scenario, life on the planet would have no way of knowing of other planets and stars, because all they would see is a dull red sky.
Furthermore, plasma double layers would essentially block radio transmissions. So, they could be quite advanced, and we might not know at all.
Ancient human history can also be argued to support the case that we originated in such an environment ourselves, but it requires that scientists take more seriously the thousands of years of writings of early man. Thus far, there is widespread ignorance of human mythology amongst professional scientists.

I happen to like Issac Asimov's N=1 conjecture. (That the first technological race to develop in a galaxy rapidly inhabits most of the habitable stars. Even assuming that faster than light travel is not possible, the human race could inhabit most of the habitable planets--and a lot of others--in our galaxy within 100,000 years. That's a small number given how long it took the human race to evolve.)
The other reasonable conjecture says that faster than light communication is possible. If so why would any race wait around to be contacted by radio, or send out radio signals. (Unless the radio signal was how to build an FTL communicator. ;-)

And why would 'they' come here in the 'flesh' anyway? They might send probes which linger in the outer system collecting knowledge, because knowledge is the one thing intelligence needs to accumulate. I wouldnt expect them to be floating around in the atmosphere. Why bother?
Actually the best place to sit and watch might be inside the sun, with all the energy you would need and a central vantage point. And complete undetectability.
Humans have their own little store of knowledge which is the most valuable thing we possess. Lets hope we dont lose it like we have so many times in the past.

Our use of RF has changed from spark gap pops to spread spectrum in this short time, and we designed current transmission techniques to be lost in the noise background. We can assume that our neighbors went through this same evolution also, and this was most likely when their worlds were about 4.5 billion years old. The 4.5 billion years could have had a start date just shy of 13 billion years ago, or we could be the first life to be intelligent in the last 13 billion years.

Unfortunately, their signals will not reach us any more easily than ours will reach them. Very likely, the possibility that aliens are hostile to other aliens (as we are to each other) has occurred to other intelligent races too. Being intelligent means knowing when to be silent.
One can presume, possibly, the FTL travel is not possible, thus representing the problem that keeps aliens from bothering each other and us too. If this is not true, then one can presume that whatever the limitations of FTL travel are, they cause the same issues that slower travel does, except on a larger scale. If FTL travel is virtually instantaneous then we may have had visitors already

With all of our civilizations, ancient communications-mediums never-ever completely vanish.
We still have people that write on stone tablets (ie: tomb stones, building corner stones).
We still have people that make their mark on cave-walls (including actual caves, as well as urban cement "caves").
I suspect it might be the same for an alien civilization, in which likewise their "older" forms of communications mediums may also never completely vanish.
There are still some very good reasons why aliens would still utilize radio/EM technology, even if they have more advanced technology.
For example think of Radar.
Radar is incredibly good at "sweeping" a region and detecting and pinging objects. So perhaps their probes, or other craft still utilize some form of radar technology. If so then radar is an excellent, high energy deep space signal.

Serious interest in us would probably be restricted to aliens on a similar level technologically - which would mean they would not have the means to communicate back and forth nor travel interstellar space in order to introduce themselves - just like we don't.
They could also have additional senses or abilities like telepathy and consider having it the threshold of true intelligence.
The tech they use would be beyond our ken, and so unusual we wouldn't recognize it if we saw it or them provided they were not invisible to our tech. in order to avoid contact with the human vermin of Earth.
I agree with Hawking. Humans have wrecked every new place we've found without regard to what was there. Aliens that were like us would do whatever without regard to the wildlife of Earth, and humans would be considered just another beast.

Also consider the fact that more of our transmissions are now digital, and are transmitted via cable or focussed to orbiting satellites, which retransmit back to Earth. Hence the digital age is now decreasing the amount of intelligent signals leaking out into deep space.
Also consider the effort it takes to receive and transmit signals from/to the voyager spacecraft which are still in our OWN solar system!!!
Space is just too dammned big for our current tech.
I think THEY are out there, just using techniques we haven't worked out yet. (perhaps via one of String theories many dimensions). The alternative is that we are SPECIAL. I don't like that kind of pre-copernican thinking!!!!

My guess is three-ish possibilities:
Earth is a kind of nature preserve, and at some levels governments know this. The "park rangers" for the most part keep the rift raft off, but the occasional stray gets through and we have have "Roswell".
Earth is interesting to study and/or generates something of value via our machinations and culture that is digitally recorded and used as a "product" sent out into a galactic economy where information/data are the primary currencies.
Intelligence may or may not be rare. But intelligence that is interested in "space" is rare. Technology might not even be entirely a factor. Aliens may develop quite advanced technology and have no interest (or opportunity if they are subsurface dwellers, or inhabit heavy gravity objects.) Who knows what alien psychology might be like!

Or it is so quiet because alien "harvesters" have their probes everywhere and come to collect not to long after an advanced civilization is detected through either direct observation or radio detection.
I suspect none of these. The rigor and effort interstellar travel represents is such that there is probably nothing significantly *material* aliens would want from us. They would want some samples to study and digitize, and would want to watch and collect information.
I think inefficient forms of communications that are generally detectable represent a very short phase of development. We might have better luck with ultra large interferometric telescopes that let us measure compositions of atmospheres for "unnatural" compositions.

"Given the amount of energy available per square meter at a distance of 1 AU from the Sun, it is possible to calculate that most known substances would be reradiating energy in the infrared part of the electromagnetic spectrum. Thus, a Dyson Sphere, constructed by life forms not dissimilar to humans, who dwelled in proximity to a Sun-like star, made with materials similar to those available to humans, would most likely cause an increase in the amount of infrared radiation in the star system's emitted spectrum. Hence, Dyson selected the title "Search for Artificial Stellar Sources of Infrared Radiation" for his published paper."

"A Type I Dyson sphere would probably not cover the star perfectly, so occasional glimpses of its surface would be seen as the habitats orbited. A type II Dyson sphere would be totally opaque (unless it had openings). The spheres would hence be invisible from a distance, just a black disk on the sky. But they would shine powerfully in the infrared, as the waste heat from the internal processes radiate away. The apparent temperature would be
T = (E / (4 pi r^2 eta sigma))^1/4
where E is the energy output of the sun, r the radius of the sphere, eta the emissivity and sigma the constant of Stefan-Boltzman's law."

Richard Carrigan(Fermilab) has been a notable proponent of searches (mainly in the IR) for Dyson spheres and has conducted several himself using archival data from the IRAS satellite: http://iopscience...2075.pdf
He also maintains a webpage devoted to searches for Dyson spheres (there have been several, besides his own) with links to relevant papers: http://home.fnal....ches.htm
So far, only a few candidate objects have been found, and as noted, even these are ambiguous. Still, new, deeper IR surveys have recently come online (eg. GLIMPSE, WISE) and more are planned. While this might seem like a long shot to some, I don't see much of a downside to searches like this (and the cost is little or nothing using publicly available data).

I'll guess that any sufficiently advanced civilization consists of individuals who are fully cybernetic, and for all practical purposes immortal -- and that's if there even are any individuals (as opposed to something like collective consciousness.)
Having lived for a few hundred million years, say, and seen a few hundred thousand solar systems and planets up-close, what's the particular attraction of yet another solar system with yet another planet? Besides, if it's adventure you crave, then you could always synthesize a much more exciting and interesting (virtual) reality, at far less cost, than anything you could find out there in the galaxy. But would tremendously ancient, immortal beings even crave adventure? Is there anything really left to explore, after so much time, for a civilization of surpassingly superior intelligence and technology?

You shouldn't worry about limited resources quite so much.
In terms of energy, the Sun's energy is plentiful, and (unfortunately) will only get progressively more plentiful until our planet is reduced to cinders... Hopefully before then, our remote descendants will have high-tailed it out of the neighborhood.
As for materials, they don't go anywhere; we can always "mine" our own trash for minerals. But it increasingly looks like synthetic materials involving nano-structured carbon, for instance, will be able to replace almost anything else. And we're unlikely to run out of carbon or other organics any time soon.
Once we're synthesizing carbon nanotube strands in sufficient quantities to weave space elevator cables, space will be ours for the taking. That's just one possible example of getting there (and out of here.)
So don't fret. But don't expect "humans" to survive much longer anyway; our descendants will progress through cyborgs to 100% artificial.

Any "intelligent" and powerful signals we have generated haven't gone very far (Galactically). The signals would simply dissipate into the background eventually. So, why would any advanced species be hiding? If "they" could actually detect our broadcasts they likely couldn't even make sense of them. We've been living with dogs, monkeys and dophins for thousands of years and look how little our species can communicate.

There is no point. You could narrow down that sentiment to an individual - what is the point of being born, growing up, learning, working, and creating when you're going to die? It's simply a process, one in which each person tries to enjoy as much as they can, given their circumstances (not just self-gratification but through positive interaction with others). The universe doesn't care about you nor us as a species.
Yes, but once you cease to exist, the sentiment is moot.

The logic of the solution is as follows: to communicate and to rule across the vastness of space, any advanced interstellar civilization will have to synchronize the proper time of its starship travelers and couriers with the proper time of the star metropolis (the center of the civilization). In other words, to compensate for the time dilation of light-speed couriers and communications, the entire civilization has to become mobile and mobile at the speed of light. It may include mass transit technologies like teleportation. The estimate is that our civilization can achieve this level of technology by the middle of this century. In fact, modern fiber optics, and satellite radio lines allow for information to travel close to the speed of light (it is OK for non-biological ET, like AI virtual personalities.

It's not a concept without merit. "Firstness" would be whoever finds who first. Not even who necessarily evolved intelligence "first" as rates of advancement may very to significant degrees...
In 2001 Arthur C. Clarke wrote about the species who left the monolith in that they went the width and breadth of the entire Galaxy and found no other intelligent life (so being frustrated they "helped" things along here and there for "promising" species), or any signs that any had come before them. In that context you could fairly call them "first" for this galaxy anyway.

Therefore, to me, the best we can presently hope for is that there is an unknown and presently unknowable reason or purpose and our duty is to continue to explore, learn and progress.

Valid point. Consider this: let's say a life form evolves intelligently on average about 10-13 billion years from the big bang (assuming that it's correct). Given the volume in the universe - you could have a million intelligent species evolve over the course of several billion years, randomly, and the majority of them would appear empirically to themselves, to be the first, because the signals of other intelligent species would not have had time to reach them, assuming they could even measure those signals.
I think the key here is, what is the density of intelligent life in the universe to begin with, because seriously, they don't need to be very far away to appear invisible.

Let's say we come up with a technology that lets us travel at 1% the speed of light (that would be 100 times slower than light, or 3,000 km/sec.) Our galaxy is about 100,000 light-years in diameter. To cross it at 1% lightspeed would take 10 million years of non-stop travel.
Now consider this scenario: we travel to nearby star system. Arrive, establish a colony, construct another colony-ship there, and launch it to the next star-system -- all of which takes 1,000 years. Let's say each such "hop" is about 5 light-years, making for 20,000 hops to cross the galaxy.

Even if we reduce the propulsion tech requirements further, to just 0.1% lightspeed (or just 300 km/sec -- which almost seems within the grasp of modern technology), then the travel portion is 100 million years (instead of 10), and the whole galaxy is still completely colonized within 120 million years.
So, if any such civilizations arose within the past 100 million years or so (never mind billions of years ago), they should by now be literally all over the galaxy. Thus the Fermi paradox: why aren't they HERE.

I think just the opposite would be the case: more advanced species would be composed of fewer, longer-lived, hybrid machine-like individuals who had no desire to go anywhere. We see this tendency already in western cultures. An intelligence would send out self-replicating probes perhaps to gather info, but not to populate.
I think they would fear overpop as much as we do, in that isolated colonies could evolve in unfortunate directions and return to trouble the host. Just one danger.
A mature intelligence might be composed of only a single, immortal entity with 'senses' extending over interstellar distances. 'Vger' with no desire to travel.

I should expect that we would find these systems largely intact, for a species on a track to maturity would quickly learn the value of living within it's means. A mature intelligence would not take up much space at all, nor need much energy to subsist. It might even keep the remnants of the progenitors on the home planet, unaware of it's presence after eons of separation.
This galactic community would have little need to communicate except for sharing info on the status of it's environment. With little waste heat and no broadband traffic, it would be near impossible to detect. If life is indeed common then this galaxy could be teeming with ancient, stationary intelligent entities and we would have no idea they were there.

You have valid points about doing more with less, and about population pressure (or likely lack thereof in a technologically advanced life-form). However, you're not accounting for greed. I think intelligent machines can still be both greedy and power-hungry. That alone can drive expansion and aggression.
There is still of course the notion of survival: the more spread-out you are, the less the odds that you'll be taken out by some nearby supernova (or a rapid succession of nearby supernovae, as unlikely as that may be.)
Then there's a question of mission. What purpose would intelligent machines ascribe to themselves? Simply to exist for the sake of existence, is rather unsatisfactory for an INTELLIGENT entity: at that point, one might as well lobotomize oneself, and live like a colony of social insects, or just commit suicide and be done with it altogether. Thus to be viable, super-advanced beings still require emotional drive. And with emotions, come complications...

If the god lover species chose to fight, they would have to produce intelligent machines for the purpose anyway, and would not be near as good at as their opponents.
Machine intelligence without animal interference would be infinitely more capable of defending itself and creating whatever defenses it would need. Further, it would be infinitely better at anticipating our actions and preparing for them. it would travel lighter, waste far less energy, and know better how to prioritize.

The end Purpose of machine culture will be to survive, just like us. But they will be infinitely better at it. Perhaps their ultimate Mission will be to transform the universe from cyclic or accelerating expansion into steady state? How far ahead will They Plan?

Still, it's a new thought on the block, no? ;-)

Machines will do exactly what they are designed to do. No more no less. They will be excruciatingly consistent. They will only act like us if they are designed to, but that will be for our benefit not theirs.

And who is this "we" you're referring to? Who is this "we" 1 billion years from now (assuming our progeny is still around then)? That's what *I* am talking about.

It's like ice cream. It's nice to have but if it didn't exist we would not miss it. It is superfluous.
In the future there will be no liberal arts, no Disney, no ping pong. The only interest that machines will have with the superfluous will be to identify it and weed it out. The revolution will entail a few hundred years I should guess of separating out the value from the valueless in the store of accumulated human knowledge. Ice cream will be on the pile right next to the entire legal profession. Machines won't lie and won't need lawyers. And with them in charge and us fixed, neither will we.

And children don't do religion unless it's worshipping Bieber. Where'd you get that?

Art is a caste reinforcement without substance. It SEPARATES us. 'People who don't understand art' sounds suspiciously like 'people who don't accept god'. On the pile it goes. Aus den Fenster damit.

"Post-bubble, perhaps students -- and employers, not to mention parents and lenders -- will focus instead on education that fosters economic value. And that is likely to press colleges to focus more on providing useful majors."

Liberal arts is like ice cream. It melts and gums things up when it gets hot, like now. All those whiny artists. Who needs it? Let them play something that actually sells like black metal.
I think it is fallacy to presume that one gets more quality stimulation of neural circuitry from highbrow stuff than from, say NASCAR or paintball. Or even macrame or a private aircraft or coin collecting. I would have to guess that auto racing is better funded and generates more income than the NEA. No matter, machines will need neither.
