Advanced civilizations should be indistinguishable from nature.

I read this whole article and I can't figure out what they're actually claiming, other than some version of "we should try to imagine that things might be different than we imagine."

can somebody (or ChatGPT) take a stab at making this make more sense?

tiahura• 2 years ago

Advanced civilizations may be indistinguishable from nature, as they prioritize sustainability by integrating their technology into their planet’s biosphere rather than expanding destructively. This challenges assumptions like exponential growth and the Kardashev Scale, suggesting that undetectable, harmonious technospheres could be the norm. Researchers argue for rethinking planetary histories, sustainability, and life beyond Earth to better understand the Fermi Paradox.

sudhirj2• 2 years ago

We’re not considering the possibility that most civilizations will consider progress to be a move to a utopian state of living in harmony with nature, with buried machines. Not paving the planet and the sun with solar panels.

The 'plastic rock' formations off Brazil [1] may be something? Like if advanced civilizations incorporate some element of time/pressure/environments to something, the plastic that has melted, merged, and reformed into rock formations may produce newer elements that turn out to be breakthroughs?

One thing that immediately came to mind upon seeing the title is the way that efficient (digital) radio communications look much more similar to noise (due to information density) than old analog communication methods.

The article seems to be looking at things from an energy-usage perspective. Why don't we detect Dyson spheres and other large-scale technological projects? Maybe the most efficient ways of harnessing the energy of a planet blend in with the natural processes of the planet itself.

Or, as a sibling comment suggested, maybe the civilization that makes (alien) people happiest is one that outwardly resembles the world they evolved in.

ymyms• 2 years ago

I think it's saying something like: what if it's impossible for a civilization to grow big enough or quick enough with our current technological path to make the bigger steps like harnessing the energy of our star and becoming space-faring. Perhaps instead there's some other path that looks more like nature which is why we can't detect it.

Like what if it was easier to master biology, create some kind of biologic computer distributed amongst all the living things on a planet, and load all the consciousnesses of the advanced beings onto that.

pc2g4d• 2 years ago

They claim one resolution to the Fermi paradox is that civilizations tend to evolve toward a state that resembles nature (non-industrial or non-civilizational, I'm not sure).

So the idea of a highly advanced civilization requiring so little resource extraction, or even being able to entirely synthesize all its resource needs from energy, and manage global resources in a non-destructive way, while letting the natural ecology revert to as close as possible to a pre-civilizational state.

So you see small hubs of super-high-density cities, and vast expanses of "nature". Harder to detect from space that way, thus it could resolve the paradox?

You can see our own time moving that direction with urbanization and re-greening happening simultaneously, population growth falling, and a huge effort to abolish the use of one particular variety of extracted resource.

A lot of sci-fi already makes this premise. The bright future is not one of concrete and metal, it’s sunsets and trees and lakes tended to by invisible robots, with all the ugly machines, generators and data centres buried deep in rock.

Nature isn't 'natural'by any sense of the word. But the advanced machines all tend to show an interest in maintaining natural spaces for humans to enjoy. And the machines are part of the beauty as well!

Or, a fully biologic solution, even for a space habitat as was envisioned in John Varley's "Gaea" Trilogy: _Titan_, _Wizard_, and _Demon_.

To quibble a little Gaea is not fully biological. For instance, at one point a particle accelerator is mentioned as being in the ship's shell, and both the original (well, latest) Gaea entity and later Gaby are obviously running on some giant supercomputer somewhere. The inhabitants (crew?) are certainly biological, though.

sologoub4• 2 years ago

The growth is unsustainable argument is very strange to me. We absolutely have the technology to make growth sustainable, but societies choose to go for other things because overall growth and advancement of humanity is not generally a goal at mass individual level.

For example, currently society is busy transitioning to electrified transport. Los Angeles had a vast network of that 80+ years ago (red car light rail system). We also have had nuclear power as an option for a very long time. And yet, red cars were scrapped, rail removed, freeways built, we still burn gas and what not for power, and California has a ban on new nuclear… It’s not that we can’t do all this, it’s that for various reasons we choose not to.

It’s quite human-centric to assume that all other possible civilizations will make the same choices. It seems more likely that there will be as many choices and value systems as there are possible life sustaining planets out there. This doesn’t answer the paradox of course.

https://expatcircle.com/cms/why-the-future-might-hold-troubl...

The limits of growth are real. Very real. And unfortunately, many problems we are seeing might be the prelude to the prediction.

"It’s quite human-centric to assume that all other possible civilizations will make the same choices."

Well, there should be many and we see none. This is not encouraging. While the best idea to look for life is to look for an entropy source, I think advanced live in space may be similar to us. They would need some kind of sensors (eyes, ears) and likely they would have been predators at one stage in the evolutionary path.

zmgsabst3• 2 years ago

Your first link says that in 400 years, we’ll need a second location to continue growing.

And…?

I think that actually supports the other person’s view: if your entire argument amounts to “in 400 years, we’ll need to have space stations or settle Mars with nuclear!” that isn’t really an argument against growth now.

sologoub4• 2 years ago

Those links are so oversimplified to not be useful. The arguments are for an ideological point of view and not a real analysis. Just consider that population growth is stagnating and going into decline. While energy use per capita is likely to increase, it’s not clear at all that things will continue as before even a 100 years from now. Even the AI race is seeing smaller models perform as well or better a year old ones. We are definitely in a fast growth phase of energy use there, but will it continue to grow indefinitely or will we become much more efficient and hit diminishing returns stalling further investment or plateauing energy use? Who knows… On the scale of the next 100 years, humanity can definitely meet its energy needs with nuclear and clean sources if we have the collective will. Will we? Time will tell.

theamk3• 2 years ago

You can clearly see the energy growth slowing down starting from 1980's or so.. and yet the rest of article keeps going like this is not happening, and same rate from 1650's will hold for many more years.

It won't. Population growth is slowing down, per-human energy growth is probably even decreasing compared to 20 years ago.

thrance• 2 years ago

Economic growth, in our current paradigm, requires the production of ever more goods, which in turn requires ever more energy and natural resources. That is unsustainable, because nature is finite.

My personal theory is that any advanced civilization that is capable of interstellar travel must have conquered their animal instincts and realized that growth for the sake of growth is pointless.

sologoub4• 2 years ago

These are only finite within Earth. Add even modest solar system travel capabilities and a lot more resources open up. Mining asteroids is just one idea there.

As long as Jensen can polish up some sand and sell it for 5 morbillion dollars, nature and economic growth is not finite.

svara• 2 years ago

An important point to think about, but ultimately wrong I think.

The reason that the software industry is so valuable today is not just that it's innovative, it's also that it can grow in a way that isn't strongly constrained by material.

The material required to provide one dollar of value in digital goods or services is very little.

This leads to a virtuous circle, since business unconstrained by material attracts more capital.

Basically, we can shift the physical economy to a circular cradle-to-cradle economy, and then continue getting growth from digital goods and services.

Note that this does not simply mean we'll all be living in VR - digital goods and services are growing across all industries.

For example, back in the day, drugs were discovered by massive wet lab experimentation programs. Today, increasingly components of a drug discovery program can be done in silico.

corimaith• 2 years ago

growth for the sake of growth is pointless

Is "sustainability" for the sake of "sustainability" pointful? For all we know, everything may just be reduced back to energy in a Big Crunch in the future, so the outcome is the same regardless. Is a civilization that languished in stagnancy for millions of years have any more paticular meaning than one that burned brightly but briefly?

foxglacier4• 2 years ago

The idea that we should use finite natural resources more slowly or not at all to be sustainable doesn't make sense. What are we saving them for? Future people who would also uses them unsustainably? If we're sustainable forever, then future people won't need them. If future people do need them, they won't be sustainable and won't last. So why don't we just use them up as fast as we like?

Perhaps future people will have some important but finite need for them. So we save them for that one big moment when they're used for the really important purpose that will never be important anymore in the future of the human race? Seems unlikely such a use will appear, at least not one more important than what we've already done in building our industrialized society.

adrianN2• 2 years ago

Using finite resources more slowly gives you more time to invent alternatives. Imagine what would've happened if we used up all fossil fuels we had alternatives.

sologoub4• 2 years ago

If the finite resources here are fossil fuels then the idea is to never use them again. It was a bad idea to continue using these a long time ago and it will still be a bad idea in the future. Sustainable energy production is not about deferring something, it’s about not poisoning where you live. That does not mean giving up on useful technologies. For example, synthetic hydrocarbon fuels can be made in a carbon neutral way, it’s just very expensive today. These would solve for some applications where EVs are not yet practical, etc.

patcon• 2 years ago

We absolutely have the technology to make growth sustainable

No, respectfully, we don't.

Every organism that succeeds in doing what you advocate for (growing "sustainably") is swept from the record. If life doesn't cycle (grow/shrink) or otherwise live in equilibria, life exhausts its niche on any meaningful timescale, and the universe sends it into oblivion.

Perhaps interestingly, even records of "successfully" growing are purged, because the most effective thing that persists records of life on long timescales is the descendant path of the life itself (whether that's specific DNA sequences maintained as mutational clocks by cellular machinery, or libraries of books and concepts maintained by specific civilisations), and uncapped growth collapses the informational diversity required for life to thrive and persist -- by which I mean that we, as continuously persisting living biological and cultural structures, are the best evidence of living things like us existing a million or a thousand years ago.

When the lineage dies, evidence of the experiment rapidly decays, compared to actually successful experiments that refrain from growth and collapse of their ecology. Only DNA/culture that doesn't "succeed" in growing beyond its resources survives on a significant timescale. When an overly zealous strain of life grows too much and fails, evidence of that life is swiftly and rapidly purged as well, for any later life that cares to try to look.

theamk3• 2 years ago

I don't why biological limitations restrict humanity's long-term future.

We are already ignoring them - right now it's freezing outside, and no human could not survive in such weather using biology alone. I am also living in a city which is way too dense to sustain natural human society.

There is always a risk of entire species dying out, for example via global war, or everyone suddenly deciding they don't want technology and then freezing to death in the winter; but there are no universal long-term limitations. At some moment there will be independent colonies at other worlds, and then humanity will be eternal.

hshshshshsh7• 2 years ago

Bullshit. Nature evolves through small random mutations. Random mutations can't build structures like Aeroplane or a Watch. That requires thought and creativity. Advanced civilizations would continue to use creativity. And hence making them distinguishable from structures that are present in Nature.

defrost• 2 years ago

So birds and circadian clocks accurate to seven years are not the result of random biological mutations?

hshshshshsh7• 2 years ago

You can tell a bird is built through evolution pretty easily. Lot of give aways in the structure which serves no point or is badly designed because mutations can only change small changes at a time without being able to think through to future.

I am not saying random mutations can't build entities that are accurate or can exist in reality. Of course they can. But it's also pretty obvious these structures are result of mutations and not creative thought.

svieira• 2 years ago

That is the other possibility.

8bitsrule• 2 years ago

Intriguing new perspective.

Random mutations can't build structures like Aeroplane or a Watch.

Perhaps that's why nature evolved us (randomly or by some not-entirely-random 'mechanism' we haven't spotted - does it matter?) (Consider how many bacteria live in the human body. Could we even exist without them? ) ... WE could be the experiment that builds structures ... and is able to let the whole works look at itself.

hshshshshsh7• 2 years ago

This assumes nature has an intent, a plan and is conscious at a higher level. Is that what you are saying?

ausbah• 2 years ago

what? evolution isn’t just random mutation, it’s also environmental selection & recombination (for the most part iirc). in the right environment, if some species evolved some mechanism like flight or time keeping - so long as it would be beneficial to survival in the environment it will endure. it’s definitive proof you don’t need a conscious process to create complexity. sure there’s baggage & imperfections, but it certainly gave rise to higher order phenomena like consciousness & intelligence - if only by accident :)

hshshshshsh7• 2 years ago

Yes. What I meant was nature doesn't generate a mutation based on thinking through what is good for the species or individual. The mutations just happens randomly and the ones which are beneficial continue to pass through because it ended up in the genes that reproduced.

Unlike designing a plane for example which consists of thousands of decisions carefully thought through based on a human objective.

Animats2• 2 years ago

Well, yes.

Organized human civilizations go back 2000-3000 years. Industrial civilization at scale goes back less than 200. A useful starting point is the Liverpool and Manchester Railway (1830). This the moment when the industrial revolution got out of beta, and, quite literally, picked up steam.

Extractable natural resources are somewhat finite. Sometimes, with more inputs, you can get more output. Fracking is a modern example. An older example is taconite, the low-grade iron ore (15% iron) mined after the reserves of high-grade ore (65% iron) were exhausted.[2] Gold and rare earths are extracted at great expense from very low concentrations in the raw material. At some point, extraction in high volume becomes impracticable.

We're only two hundred years into high-volume mined resource extraction. The USGS has a Critical Materials List.[3] Most of the current problems are political and commercial, not outright shortages. USGS lists known reserves for mined resources. Most have at least a century of known resources left, but not a millennium. On a time scale of civilizations, that's not long.

Recycling is a battle against entropy. Almost all gold is recovered. About 80% of aluminum is recovered. About 60% of steel is recovered. Each time around, you lose some through dispersal into forms not easy to collect and recycle. So that, too, has a diminishing returns problem.

Sometime in the future, perhaps closer than the distance in time since Oxford University was founded, most of the minerals will no longer be available in large quantity. It will be a slow, but difficult transition.

Biological systems, though, mostly keep shuffling around C, H, O, and N. That's been working for over 300 million years now, pretty much recycling the same atoms. Long term, on the scale of millennia, systems running on the weaker bonds in that space can go on for millions of years. That's the default mode of planetary operation.

Energy isn't a long-term problem because forms of energy are convertible, and wind and solar keep working as long as the sun does, at least if there are enough materials left to build generators. That looks like a long-term win on the scale of thousands of years. Millions, though...

It's quite possible that industrial civilizations have a finite lifespan, bounded by material availability. Doesn't mean there can't be sentient civilizations. Or that they're limited to "nature". Biological systems can be engineered, too.

But you don't get interstellar travel out of biology. Too low-powered.

zmgsabst3• 2 years ago

I largely agree, but a few quibbles:

- the Great Pyramid is closer to 4600 years old

- we will always have common crust elements, eg 27.7% silicon, 8.1% aluminum, 5% iron, 3.6% calcium, 2.8% sodium, 2.6% potassium, and 2.1% magnesium; so the question is those and biological elements (carbon, hydrogen, nitrogen, and oxygen)

- you can probably do space travel from that list, which gets you easier to consume versions of those elements as well, eg asteroids

- and from there interstellar travel is possible.

nradov• 2 years ago

We don't have a reliable age for the Great Pyramid. Since we can't do radiocarbon dating on rocks, all of the estimates are based on somewhat circumstantial evidence. It could be much older, possibly with some more recent maintenance. I'm not claiming any particular age, just that we don't really know.

Aphataeros• 2 years ago

The Oxford University timeframe comparison hits hard. It's a sobering way to visualize just how brief our industrial window might be. But I think we're missing some fascinating possibilities here.

You're absolutely right about the recycling entropy battle - those diminishing returns are brutal. But I'm curious about where biological innovation might shift this equation. We're already seeing organisms that can work well beyond the traditional C/H/O/N sandbox - bacteria that reduce metals, engineered microbes that synthesize quantum dots. This hints at possibilities that blur your distinction between biological and industrial approaches.

The interstellar travel conclusion particularly caught my attention. While current biological systems are indeed low-power, that very efficiency might be what makes them perfect for long-haul space missions. Imagine hybrid systems where bio-engineered organisms maintain spacecraft over generations, working alongside traditional tech. Maybe slow and steady wins the interstellar race.

I'd argue we're on the cusp of even more radical transformations in materials science. What if atomic-scale manufacturing fundamentally changes our relationship with scarce resources? The jump from 65% to 15% iron ore might look tiny compared to what's coming. Maybe we're not facing a binary choice between current industrial systems and purely biological ones. The sweet spot might be in hybrid approaches that combine biological resilience with industrial capability.

Curious to hear your thoughts on this - particularly around how engineered biological systems might reshape our assumptions about resource constraints. There's something compelling about the idea of building civilization's next chapter on that 300-million-year track record of biological innovation.

Animats2• 2 years ago

bacteria that reduce metals

Separate metals from organics, yes.[1] Reduce metals, probably not. Reduce means to pull a metal out of its oxide. This is way uphill energetically. It is usually done by heating the oxide to a high temperature in an oxygen-poor environment. The other direction, oxidation, produces energy, and there are some biological processes that use that.

Still, there are some bacteria which manipulate manganese.[2]

What if atomic-scale manufacturing fundamentally changes our relationship with scarce resources?

I used to know Drexler, the early nanotechnology guy, back when nanotechnology meant pushing atoms around by mechanical means, rather than surface chemistry. Not much came of that. It's hard to apply enough force to break strong molecular bonds apart. IBM did manage to spell out "IBM" with xenon atoms, but xenon is inert and doesn't bond strongly to anything. No strong bonds to break.

Asteroid mining is potentially possible. Somebody will probably try it for gold and platinum within fifty years. It's unlikely to become cost-effective for cheaper metals.

As far as we know (but we could be wrong), interstellar civilization is the business of a Type II civilization on the Kardashev scale. They can extract fusion energy, raw materials, and information from multiple solar systems.

Australian Aborigines are at 50,000 or so, depending on your definition of "organised".

And, inferring from the article, I kinda like the idea that advanced civilisation fade back into nature. Modern humanity is about 100,000 years old. Is that long enough for a civilisation to rise, peak, and fade back into nature? It's a fantasy trope, obviously, but it's cool to think about again with this angle.

But you don't get interstellar travel out of biology. Too low-powered.

The thing is interstellar travel makes no sense except in science fiction books: there's literally nothing of interest to be worth trading in other planetary systems, and trade has always been the motive for maritime exploration, because it's what get you the massive funding such endeavor requires.

And btw even close space colonization doesn't make any sense either: we may end up with a vanity base on Mars before realizing that it costs a lot, for living conditions that are more harsh than at the top of mount Everest. Even if world population wasn't plateauing and headed to a decline, colonization of Siberia or even Antarctica would make much more sense.

Arch485• 2 years ago

Interstellar travel solves the "finite resources" problem. Granted, intrastellar travel can do that as well: Earth's moon first for its H3, then use that as a launchpad to go other places for resources that are limited or running out on Earth (iron, silicon, gold, etc.).

exq• 2 years ago

Mars colonization doesn't make much sense, but building O'Neill Cylinders when humanity runs out of space or energy on Earth might.

interstellar travel makes no sense

For vacation or finding new spices to sell, no, but if you've exhausted all the matter in the solar system or humanity outlives useful solar output from the sun and fusion energy is still +20 years away, there isn't really a choice.

The time it takes for interstellar travel doesn't make sense on human time scales, but people still plant trees knowing they will not live to sit under their shade.

Colonization would, I think, not require economic justification. Using transportation and communication barriers to facilitate isolation or at least localization may be important to some people.

With vast discretionary spending, people would be able to sacrifice some pleasures for pleasures related to achieving a long-term impractical goal. Space travel does not have to be the most efficient means of enjoying life to be a human choice.

A colony in Antarctica would be much more practical than one on the Moon, but a Lunar colony is more romantic.

If material trade is not worthwhile, conquest may be somewhat discouraged. (Some people might wish to rule all of humanity or convert/exterminate all heretics, so no distance would be perfectly safe, but a perceived threat in Antarctica would be easier to eliminate than a perceived threat on the Moon or in the Large Magellanic Cloud.)

In that lens, there seems to be two obvious paths: expand to new planets or climb the Kardashev scale and use your limitless energy to recycle every atom.

As long as you can get to one of those stages before you run out of the required industrial capacity you should be fine.

If we absolutely had to, I think the human species could moonshot our way to either fusion or asteroid mining inside a couple decades. At least with our present resources, maybe not in a century from now.

philipkglass2• 2 years ago

See "The Age of Substitutability (What do we do when the mercury runs out?)"

https://www.osti.gov/servlets/purl/5045860

The conclusion: most material demand is for elements so common on Earth that supplies will never run out. Only more energy is required to deal with super-low-grade ores (like 10% Fe basalt instead of 15% Fe taconite). The rare elements can largely be substituted so that the residuum of non-substitutable demand can stretch supplies to millions of years.

As you'd expect of a paper coauthored by Alvin Weinberg in 1975, the energy solution proposed is "fission breeder reactors" but there's a nod toward the long term potential of solar power and fusion.

joe_the_user• 2 years ago

Yes, a lot of people on this post have mentioned that with proper planning, a more long-term perspective and consideration for human well-being, growth doesn't have the same limits.

Sure, but if you had a consideration for human well-being, if you had a society where people thought about "what should things look like in a hundred or a thousand years" you wouldn't have any impetus for exponential growth.

I'm really surprised at how little concern there is for conserving metals and findings ways to recover them from landfills. Any amount of plastic, even a single straw, makes people angry, but you can waste a pretty large amount of metal or clay or any other natural material and it seems almost nobody cares.

fractallyte• 2 years ago

The problem is that it's very difficult to think in, or even imagine, a new paradigm.

Here's the paradigm: the introduction of technology (starting with the wheel?) led us inexorably down the wrong path, and only in this century are we beginning to see its civilization-ending effects.

Technology breeds new technology. It's seductive (all those cool mechanical/electrical/quantum-mechanical problems to solve!). It relieves many burdens, and makes life easier - but then leads to explosive population growth dependent on technology (https://en.wikipedia.org/wiki/Haber_process). And attendant to this, pollution and environmental degradation: a slow erosion of life-sustaining processes.

The path of technology inevitably leads to a dead end. There's no escaping our vast population: 8 billion individuals is a lot, by any measure. It is the root cause of all our environmental problems. Can we creatively apply new technologies to solve this problem in time to prevent ecological and environmental collapse? We're right in the middle of the experiment, and there's no guaranteed outcome...

Imagine if we had chosen an alternative path to "civilization" without mechanical technology - what would it look like? It's easy to mock the idea of "living in harmony with Nature", but what if that's the only way to a sustainable human civilization?

the introduction of technology (starting with the wheel?) led us inexorably down the wrong path, and only in this century are we beginning to see its civilization-ending effects.

It is interesting to think about what technology harbored the destruction of the civilization said technology ushered in.

For context, the wheel is estimated to have been invented around 3,500BC, while we've had structures and systems that resemble and arguably are foundational to today's civilization: the cities that even older than wheels, like Argos, Athens, Plovdiv, Jericho, Thebes, Larisa, etc.

Ironically, you are already more advanced than you can imagine. In your human form, you set yourself apart from existence. Most humans don't identify as the the ground of reality, but you are as much as you are human, just as the rocks and trees are, and so on.

OMAM's "Numb Bears" track off their "My Head is an Animal" album is delightful. We are already there.

There are still plenty of things in nature we don't fully understand. In some sense fungi might be more advanced than us, but nothing on earth seems more inclined towards growth and omnivorous consumption as humans. It's almost tautological that many people think our own qualities are markers of sophistication among lifeforms. We're the best because we act a certain way and acting that way is the best because we do it.

This has all been "hacked out" in sci-fi, where the techno VS bio ideas have been explored and quiet VS LOUD civilisations are thought through. To put things into perspective, we are still discovering VERY LOUD types of phenominon eminating from deep space, and puzzling over what they might be.And if we can miss and not understand every type of pulsar and black hole collision,stellar mergers, etc ,etc, then it is presumptuous to to speak about exo-civilisations energy signatures in any absolute terms.

Some, probably not all. Same thing with the dark forest idea: some may buy into it, hard to argue none ever making a grab for more. Having so much more stuff seems like a pretty robust dominant strategy against a bunch of smaller terrified entities hiding in the forest lobbing relativistic missiles at discovered others (such lobbing itself being somewhat self-exposing). And at some point shouldn't von neumann probes let one dominate a forest/galaxy if growth to rearrange tons of natural-looking matter really must take vast amounts of time?

Article does a bad job summarizing the great filter position, and seems unaware of the follow-up on grabby aliens -- the latter being fairly convincing as a resolution to the paradox.

I don't know why each time on topics about Advanced Civilizations they mention Kardashev Scale, species of types I, II, etc. ? All those energy-centric speculative ideas are simply stupid. "Civilization" is modern concept and it's not isomorphic to "Intelligence" nor intelligence is a long-preserved property of any system per se. What we know so far is Nature allows to exist systems that can show some unusual (statistically speaking) properties, although connecting those to necessarily "interesting" information-processing formations is IMO wrong. Even AI (eq. AGI) is possibly a short-term phenomenon - who knows if "smart matter" or "smart energy" can ever be distinguishable from their "dark" pairs.

This is science fiction, not science. If Star Trek didn't exist, nobody would think this way. It's wild how art can so powerfully colonize the minds of people to the degree that they believe their unfalsifiable assertions about the universe just happen to adhere to ideas about the world that were designed as metaphors for the human condition.

When people do not read Stanislaw Lem, they must reinvent him.

Advanced Civilizations Could Be Indistinguishable from Nature
