>We may be a phenomenon as uninteresting to them as ants are to us; after all, when we’re walking down the sidewalk we rarely if ever examine every ant along our path.
Not really the most convincing argument. There are professions that study ants. And I'm sure I'm not the only person on this forum that has a casual interest in observing ants.
Pretty sure aliens would still be interested in us even if we were as primitive as ants.
Ants are interesting because of the complex behavioral systems emerging from their comparatively simple biological systems, reminiscent of the game of life.
Seeing the insane complexity of the human condition (look at the amount of scientific disciplines we come up with) and thinking "nay, this won't be interesting to a higher mind" feels awfully dismissive.
sure, depending on the leap of sophistication we may appear like... rocks, I guess? But I can't even begin to conceptualize to what in comparison we'd appear like rocks. Anything of that complexity probably is multiple magnitudes beyond our comprehension anyway, and therefore not really part of the discussion
Recently I had a bunch of snails appear out of nowhere all over the garden. And I spent a whole lot of time, trying to figure out what they were feeding on, cuz some were getting really big. The whole thing was quite fascinating...like how the hell were they producing these huge ass shells without tearing all the plants apart? So I call a good buddy over (PhD in bio something or the other) thinking he would be as fascinated. And guess what...he shows up and all he wanted to do was cook them. So much for higher minds.
(we didn't btw)
Did you try talk with them? They are probably much more like us than we are like 100 billion year old civilizations. They might find us interesting to look at but the proverbial bird watcher doesn't try to sit in the nest.
In Germany I only ever eat helix pomatia[1]. Nowadays, they are under nature protection. Only the consumption of cultivated snails is allowed. They are related to mussels and taste similar. I can especially recommend snail cream soup.
I seriously doubt the human condition seems complex to a species that went through this stage a billion years ago.
Or even a million years ago.
If we ever invent a time machine I doubt we'd learn much from humans of 10,000 years ago. There would be some surprises for historians and archaeologists, but we certainly wouldn't treat them as cultural or technological equals.
So the horizon of interest where an encounter would be fascinating and worth the time and effort but not devastatingly disruptive to either side is probably only a few millennia.
But let's call it +/- 10k years, to be generous.
Compare with the age of the universe, or even of the galaxy. It's really not a big proportion of the available time.
"If we ever invent a time machine I doubt we'd learn much from humans of 10,000 years ago. There would be some surprises for historians and archaeologists, but we certainly wouldn't treat them as cultural or technological equals."
That's only your opinion, and it's most probably wrong. These guys were capable of feats you can only dream of. And you could be very surprised at their level of sophistication, which might appear higher than us on many levels - if not on all levels.
This. And to add my own expansion to this, the number of ants studied by humans is effectively zero.
First, out of all the ant biomass, humans have only seen a very, very tiny amount. Ants are so numerous, and so ubiquitous, Google claims 10 billion billion. Yet this number seems incredibly low, for apparently (wikipedia) some ant colonies have 100s of millions of workers.
Regardless, as a human, can you imagine trying to visit each ant colony? How about if you lived just as long as an ant, or thereabouts? Say, a few years?
How about ant colonies which appear, die off? And how about the fact that ants have been around since the dinosaurs, and our modern civilisation has been around for a few hundred?
And how about if you are a researcher? Let's say you stand back, and watch the ants. Do the ants even notice? Especially the main colony?
Or are you looking at a few out of endless numbers? What do they report when they get back. Do you even need to be near the ant colony to watching them?
And after you've looked at 100 ant colonies, do you need to look at another 1000? Million? We keep discovering subtle branches of insects, so why would a.. I dunno, being comprised of energy, find different (after the first 1000) in a species with a bunch of meaty limbs?
You just made me feel a little sorry for all those millions of ants who get back to their colonies and get ostracized for wild stories of giant aliens stomping on their brothers and lighting them on fire with concentrated beams of light.
On the bright side, their version of "Ancient Aliens" is probably a lot more factual and based in reality.
We have devoted large amounts of time and resources to studying the differences between seemingly similar ant colonies, and we have lived alongside ants for our entire existence as a species.
Imagine now that we had never seen an ant, had a totally different biological origin to the ants, and had no idea why they did what they do because we had no cultural conception of them as an entity.
This is missing the point. We might be interested in ants, but the ants would not be interested in us, because ants cannot understand us.
We can prod and research ant hills all we want. But all ants will ever see are some unexpected occurrences - maybe a very unusual scent which they can't place, or some food which wasn't there earlier, or an unexpected plague of ant death - which they will forget almost instantly.
It will never occur to ant-kind that they're even being studied, because ants have no concept of what "being studied" means.
There is nothing at all in the ant (hill) mind capable of understanding that a creature like a human might exist, never mind how to communicate with it.
So we can do what we like, and we will remain not just invisible, but unthinkable - forever.
I don't know about that - we don't have any real scale equivalence in actual life forms so I'll use celestial objects as an example. The movement of other planets has almost no impact on our daily lives - the moon may impact the tides and the sun leads to our day night cycle but we can't effectively impact that and so, for the average person, life goes on without more than a momentary thought given to how things are going on up there. Though, we are all vaguely aware that we could suddenly and arbitrarily be killed by an asteroid impact (much like a colony being arbitrarily chosen to become some kid's ant-farm - or being run over by a truck) it isn't in the front of our minds because we need to get back to filling out that TPS report.
Still, as a society, we have a number of dedicated individuals that do study celestial movements and would try and prevent a sudden asteroid impact, and we all do remain vaguely aware of what's going on up there. So I'm not certain how much I agree with the fact that ants cannot understand us. Sure we can't sit down and have tea with an ant and talk about the weather, but if the moon was a gigantic dragon that just moved really slowly in a mostly predictable manner then how we interact with it might not be particularly distinguishable from how we interact with it when it's just a chunk of rock.
A good parallel to think of here is probably Discworld, I might suggest reading The Light Fantastic if you never had to get a bit of a sense of how we might interact with celestially sized lifeforms and just how one-sided that relationship could potentially be.
We might not be unique in those senses. If DNA and carbon based life is the standard then we are likely more similar to most life in the universe even if we have small differences in physiology or culture. We don’t share a direct biological origin but we are still made of the same stuff, probably originated under very similar conditions, etc. Unique forms of life likely develop under equally rare conditions in exotic environments. We’re probably just run of the mill meat bags.
I disagree that Aliens even if we share the exact same building blocks would look similar to us. For example even for planets that would be habitable for us would have minor differences in atmospheric pressure, gravity, the types of radiation their star produces would result in drastically different evolutionary paths. Also even if there was a clone of our solar system evolution would be random and the life would look different from each other, I mean look at Australia, or even look at Earth's history the fauna during the Jurassic looks way different than what we have today.
Small differences here means within the realm of what’s possible to build out of organic molecules. We’re talking about averaging life across the span of a galaxy. By unique and exotic I meant unlikely life forms like Boltzmann brains or sentient planets. We are probably one out of a million sentient, organic, sexually reproducing species. Once you’ve seen a few thousands of these you’re probably bored.
Last time a new mammal was discovered here it was international news.
If an alien civilisation has trillions of trillions individuals, there must be quite a bit of them interested in any possible niche. This assumes that an interstellar species would be naturally curious.
There are, literally, millions of planets that can sustain life as we know it. Assuming a human-like mind, that alone is enough to reduce the interest in alien life as something mundane.
>There are, literally, millions of planets that can sustain life as we know it.
There are probably x amount of planets that can sustain life as we know it. We haven't even verified the existence of millions of planets.
https://exoplanetarchive.ipac.caltech.edu/docs/counts_detail... shows only 4331 confirmed exoplanets, of those we've visited 0 and are still largely guessing as to their atmospheres, weather, temperatures, seismic activity, etc. Not to mention some we've found in the "goldilocks" zone are likely regularly sterilized due to the conditions of their orbit and their stars.
We don’t seem likely to leave the solar system any time soon, so that could easily be the case. Especially if there is any lag between detecting say radio waves or whatever they find interesting and a ship showing up.
The other consideration is visiting other stars may be possible and extremely expensive. Colonizing at say 0.001c is possible, but very slow and likely requires generation ships. Hardly worth it so your descendent can visit some primitive culture who might not be around when they get there.
But if there are so many ant colonies like us (and I would say we're very interested in alien life) then I would assume at least some of them would be interested in us too.
we may not study all ant colonies on the planet, but we certainly check all islands, and if there are ants, we will at least check if those ants are the same as other ants we have already seen.
> I'm sure I'm not the only person on this forum that has a casual interest in observing ants
From Wikipedia for "ant":
"More than 12,500 of an estimated total of 22,000 species have been classified."
From our human perspective, we are interested in ants. Everybody has seen ants. Everybody is curious about ants.
From an ant perspective, humans scarcely exist. There are 10,000 ant species that don't have a relationship with humans sufficient to deserve classification, let alone a name.
(I also want to wonder aloud why extra-terrestrials would be more interested in humans than in ants)
Yes but there's a difference between being unable to study all ant species due to a lack of resources, and being uninterested in doing so.
I expect we'll continue studying ant species with the goal of studying all of them we can (assuming we don't wipe ourselves out or ant species out before we have a chance to).
Similarly I also expect we (or an advanced alien species) would attempt to study as many other alien species as they can as well, and wouldn't stop simply because they don't want to.
We've studied 12,500 out of an estimated 22,000 so far. It's not like we've stopped and said "ok we're good, no need to study other ant species."
> being unable to study all ant species due to a lack of resources, and being uninterested in doing so.
Of course! That's my point.
Back to the alien analogy: if we believe that human-like life is as common across the universe as ants are on earth, then more-advanced aliens might well be philosophically interested in studying us, but not have yet bothered to reach us.
They might be busy "contacting" their local human-ish specieses who they see everywhere, all the time, and not think it is important to spend time contacting similar planet #12358 on the list, that's a bit further out of the way, and could take them a million years of dedicated effort.
The lack of resources devoted to the counting of ant species is a reflection of it being very uninteresting to most people. Relative to the entire universe, our world really doesn't have many places to look for ants, and we don't need to travel faster than the speed of light to find them.
This is a good supporting point. If you actually quantified the effort and resources it would take to study every species of ant it would likely be quite small although not trivially so. Yet it is still left up to the personal interests of professional biologists to lobby for research programs. It could play out similarly on a galactic scale in which case our first point of contact might be a grad student from the biology department of the local Uni.
and not only this, even among classified species, most colonies will never interact directly with a human. when ants do come into contact with things we have made, they do not comprehend it. and when they interact with us directly, even in a mode where we are identifiable to them as an entity, they can't identify much about us beyond the practical facts that we are dangerous or perhaps edible.
And further, to the extent that we might say "a lot of ants experience people now", it's perhaps more a function of us being way overextended beyond the sustainable carrying capacity of our system.
In a world where humans somehow kept themselves from risking their own existence through limitless growth (which I'm assuming wiser intelligences would navigate better), the vast majority of ants colonies would never have any human take notice of them through their whole existence.
Even as we expand our presence and every random ant has a better and better chance of encountering some kind of evidence of human existence, it still has to know how to evaluate what it's seeing.
An ant finds a peanut. Being a smart ant, it recognizes that something is strange about this peanut. It appears to be roasted. After thinking for a while, it develops a theory to explain how lightning can ignite fires capable of roasting peanuts. Simple and obvious explanation in hand, no further inquiry or speculation about the existence of "advanced peanut roasting technology" is needed.
I mean, why would supposedly advanced creatures intentionally reduce the nutritional quality of the peanut by roasting it, anyway? Yes, definitely lightning.
Chances are ETs have transformed into a physical form that is undistinguishable from, say, planets, energy, even stars. After all, the ultimate level of technology design and sophistication is when it is not distinguishable from its surroundings.
It's hard to be sure what a 10 or 100 million year old civilisation might still find interesting. I certainly wouldn't think a few hundred years of industrialisation, and a few decades of the information technology age gives us any real idea.
This. Plus, who says those ETs are of biological form anyway? Even we are thinking about AI doing most of the work, transhumanism and uploading our minds to machines, and finally, integrating with technology. Why think that a 10 million year old civilization still has flesh bodies, needs, and curiosities?
Another comment also mentioned that ETs don't necessarily share the same interests and thought process as we do, and I agree. For an insanely sophisticated civilization, mental representations and the abstract concepts they can think about are just unimaginable for us.
This. The assumption that these ETs would appear in the same form as us, or even in the same dimension, shows us how limited our thinking is.
If a lifeform has gone through let's say million times the evolving that we have, wouldn't their consciousness and expression of life have developed probably into something alltogether different.
Maybe even something that we cannot see or hear with just our physical senses or instruments. There are many theories about this if you read on the subject, people being in contact with different species, but explaining that they came from between dimensions from example.
I think the argument is that while ants are indeed interesting to us as a subject, not every single anthill gets our attention. There are probably lots of anytime anthills in out of the way places that have never had human interaction.
an interesting point which begs the question of what is a threshold of intelligence required to lose interest in a species. and if intelligence isn't the only parameter, what are the others? predation is an obvious one, curiosity comes with a form of intelligence, what else is there?
Do the ants in your example know they're being studied?
When the European powers explored the pacific they wrote off a lot of islands as being devoid of anything useful. Now a few hundred years later these islands, mostly untouched by humans, are a gold mine for various niches of biology. Human presence is still infrequent enough that the seagulls don't seem to notice.
Not only that we've incorporated armies of scientists in to the public realm to advise on such envoirnmental/biodiversity policy issues. It's possible an Interstate Freeway project may not happen because an bunch of endangered ants live along its planned route.
This makes me think that one possible reason we havent observed any alien life is that similar to how we may avoid any sort of development or encroachment in an area containing an endangered species, we may have been marked off as too fragile to interact.
And humans are an incredibly fragile species from the perspective of a space faring civilization. If a meteor hits our planet, we are basically done. And even if that doesn't happen, we can only acquire raw materials and energy from our own planet, so we may basically just tap out all our resources before we learn to acquire it from somewhere else.
And then there is the fact that we love blowing each other up, which may not be a common trait amongst intelligent species.
Theres a few species classified as endangered ants on the IUCN Red List.
However didn't aliens crush humanity to make space for a Intergalactic Super Highway in Hithchikers Guide to the Galaxy? We aren't even endangered according to those ruling fictional aliens who epitomise the "not interested in humanity" aspect.
It's also not true that the only time ants come into contact with humans is when they're being observed. Even if aliens were uninterested in us, it wouldn't necessarily mean we'd expect not to see any signs of alien life.
In the same way an ant might stumble across a human building or notice a human above the grass, you would think if life was so prevalent in our galaxy that there would be some sign of their technology.
Basically time + the vastness of space = an insanely low probability that any two intelligent civilizations would overlap within a detectible sphere, especially with our current level of technology.
If we assume 1,000,000,000,000,000,000,000,000 planets exist in 100 billion galaxies and that 1 in 100 of those host single cellular life, that 1 in 1000 of those host multi-cellular life, that 1 in 1000 of those have animal life, that 1 in 10 of those has sentient tool-building species you then have 10 trillion planets with tool-building species.
If we assume an even distribution that's 100 tool-building species per galaxy spread out over 12-13 billion years.
Oof.
Even if you make far more generous assumptions, and that 1 in 2 planets has single cellular life and that 1 in 2 of those have tool-building life. That gives you an average of 25,000 tool-building worlds per galaxy, something like a 1 in 20 million change any star in our galaxy has a tool-building civilization.
If you remove the first billion years of the galaxy you get 12.21-12.51 billion years.
Again if we assume an even distribution and assume 140,000 light-years in diameter for a galaxy, that gives you something like 1 tool building civilization per 600,000 square light-years spread out over 12 billion years.
I wouldn't expect any given alien culture to be easily detectable and/or willing to make large scale objects we could detect.
I would, however, expect at least one such civilization would develop within our detection range. As our range increases, both in distance and in breadth, chances should get increasingly better.
I think so. Not that long ago, humans spread across the world, first organically, then intentionally. We're at the infancy of spaceflight at the moment, the equivalent of putting food and water in a raft to go to the next island over.
We'll see humans on Mars in our lifetime, like the previous generation saw humans on the moon. Assuming the development and interest in spaceflight continues, we'll be seeing generation ships departing for the next solar system within the next 500 or so years (rough armchair prediction based on nothing at all). Of course, we have some massive problems to solve first, like biology, self-sustenance in deep space, cultural, financial, etc.
Anyway, my theory that we haven't seen other species yet is that space is vast and science fiction tech for light speed and beyond does not exist. If you have technology that can reach 1% of light speed, it'll take 10 million years to fly across just our galaxy. Humans evolved somewhere within that bracket. Even if the technology is there, you're seeing not just generations but entire species develop in the timescales of traveling the milky way.
Indeed, Ants do some pretty fascinating stuff, TIL we have stuff like "Ant colony optimization algorithms" [0].
Even if we are as the aliens were 2 millions years ago, there must be something of interest in what we do? I mean, we'd be interested in life 2 billion years ago. I find it more likely that they just don't want to interfere.
Perhaps, but I think it is far more likely they can't overcome the limits of the speed of light to do any useful observing. They can't cross the distance to observe us, even robots take so long to arrive that their star dies before it gets here (not to mention our star was still forming when they sent the probe out...)
They cannot observe us directly, light just doesn't have that resolution at the distance. They can't observe our radio waves because our radio waves are only 100 light years out, not to mention the signal strength fades with distance.
Quite a few stars and usable solar systems started out 1 billion years ahead of ours. The sun is relatively late to the game. If a race was curious it could well seed the galaxy with small, smart probes, that could watch for certain signs life, record, and report back to the galaxy wide cloud, sure speed of light means that takes a long time. Sure that may take 50k years for light speed communications to reach a central location, but it would collect whatever was of interest.
Might even just be a few 100 bytes of info along the lines of somewhat evolved bipedal warm blooded beings with a basic grasp of electronics, quantum, chemistry, and atomic sciences. Haven't transitions to artificial life forms, and unlikely to succeed because of short sighted environmental policies that are systemically causing a extinction event by destroying the food chain and decreasing fertility world wide. Check back in 10,000 years and see if they surprise us.
Avi Loeb's technical work is commendable but I'm left wondering if some of the reasoning in this article counts for thoughtful contemplation.
>"We may be a phenomenon as uninteresting to them as ants are to us; after all, when we’re walking down the sidewalk we rarely if ever examine every ant along our path."
Is it helpful to ascribe human-like motives to an alien species? Projecting our thought patterns on an alien species will not get us anywhere. There could be numerous reasons or no reason in particular why an alien lifeform might visit us: they are cataloging lifeforms, they are interested in 'ants' like EO Wilson, they might want to harvest resources on our planet, etc.
> "But better yet, we could get in touch with Proxima b and entice the locals to visit and share a water-based drink with us."
There's humor mixed in this statement, so I'm not sure if Avi Loeb is being entirely serious. I take the opposite stand of "don't broadcast our presence to aliens". It's common sense that if you're out in the wild, you don't draw attention to yourself.
We like to assume they are many orders of magnitude more intelligent than us. But it might be that the human brain represents the optimum size and capability possible for a living organism to sustain, based on requirements for energy consumption and evolutionary competitiveness.
We know that Neanderthals may have had bigger brains, and may have been pushed to extinction by homo sapiens. A bigger brain will require more food and take longer to develop, potentially putting Neanderthals at an evolutionary disadvantage to humans.
Assuming the laws of Physics do not vary throughout the universe and that evolution, if "run more than once" will eventually lead to similar outcomes, that could mean aliens capable of space travel are not significantly more intelligent than us, they've just had longer to develop technology.
And given their apparent tendency to crash their spaceships while visiting earth, you might have a reasonable case for "alien idiots"...
> We know that Neanderthals may have had bigger brains, and may have been pushed to extinction by homo sapiens. A bigger brain will require more food and take longer to develop, potentially putting Neanderthals at an evolutionary disadvantage to humans.
> The braincases of Neanderthal men and women averaged about 1,600 cm3 (98 cu in) and 1,300 cm3 (79 cu in) respectively, which is within the range of the values for modern humans.
Evolution has been a mostly unimportant part of human development since at least 2 centuries ago.
An intelligent species engineers itself, not evolves itself.
If there are aliens as advanced compared to us as we are to ants, that would imply to me that life is actually fairly abundant in the universe. However just as not every anthill gets studied by entomologists, perhaps there are simply too many planets with life for a galaxy-traversing civilization to study.
I also casually deploy diatomaceous earth and other methods to exterminate ants when I come across them in or around the house. I’m glad the wandering aliens have not yet decided to use this strategy. Especially if they would find earth a desirable location for some colonial purposes.
And, after that, the article proceeds listing all the reasons why our sun, planet, and species might be very different from what you might find in other parts of the universe.
Which is actually what would make us more interesting, not less.
I think the important part of that statement is "examine _every_ ant". I don't think our ant professors have the bandwidth to investigate every ant hill on earth. We could very well be one of millions or billions of inhabited planets. Also if there are millions or billions of inhabited planets, then chances are a large proportion would have more advanced inhabitants than us. I would guess that just like here on earth, scientists would gravitate more towards investigating the more advanced species with very few interested in ants like us.
A better version of that argument might be: "if ants evolved to have higher than human intellect and technology - would they be interested in studying us humans?"
I think the answer is far less clear in that scenario.
It's possible they would, possible they wouldn't. The point is that if you project things about human intelligence i.e. "but humans like ants so why wouldn't the reverse be true? "or "most humans don't pay attention to ants so why would aliens care?"on to other types of intelligence, you're making a big assumption.
A superintelligent ant colony with an "of ant" intellect is going to be so alien to our kind of intellect that the goals are just impossible to compare. Probably same for aliens unless there are many humanoid ones for some reason.
I also think the argument isn't put forward in the best logical way, but for a different reason: another potential reason why aliens might not choose to come to visit us is that they physically can't: imagine a lifeform whose chemistry is based on liquid methane instead of water. They'd literally vaporize in Earth's atmosphere!
They could also operate on a completely different timescale. For example, shrews' metabolism is way faster than ours. Sequoias are way slower. There's no reason an alien should perceive time on the same scale we do.
Would you visit every single anthill? What if an advanced alien civilization just doesn't care after passing by thousands or millions of primitive civilizations?
Look how excited scientists get when they discover organic compounds in a comet or something that looks like microorganisms in a Mars rock. I'm pretty sure aliens would be interested in studying why I drink Diet Coke instead of water & what consuming 4L a day does to me. Maybe I should also be wondering what it does to me...
But what percentage of ants find themselves the subject of human curiosity? We look at a few ants, but not most of them. Maybe it's the same with aliens. We're just another mound of monkeys; nothing they haven't seen before.
Even if we study ants, that doesn’t mean aliens will be able to secure enough funding to launch an expedition across the gulf of space to study humans up close. Telescopes and radio waves may be the most they could invest in.
Agreed. Taking the "ant" argument to it's logical conclusion and based on https://xkcd.com/1610/, there very well might be some alien who is part of a very advanced society and struggling in grad school, and that alien's advisor (unhelpfully) is suggesting how cool it is that we earthlings manage to do what we're able to do despite how primitive we are.
Not really the most convincing argument. There are professions that study ants. And I'm sure I'm not the only person on this forum that has a casual interest in observing ants.
Pretty sure aliens would still be interested in us even if we were as primitive as ants.
