Ecumenopolises

A Ecumenopolis is a planet spanning city that can house trillions that is popular in Scifi, but could it be the fate of Earth itself? And what do such worlds truly look like?

On the contrary, if the value of life can only be judged by its loyalist consumers, than the whole concept comes from a biased point of view.

I like the argument as well, nevertheless there are lots of folks that have failed to lay out their reasoning for why they shouldn't be in jail, and shouldn't be locked out of society. Or to keep it simple, I'm not sure if a rock or dead planet is better if it has humans on it. Why is it better and how is that measured. Would it be even better to put mechanical and electronic things on it instead of humans?

[@veejayroth]

@@barendscholtus1786 I would argue that there is very likely no true objective morality and therefore any judgements on "goodness" or "badness" of anything or anyone are inherently rooted in some type of subjective preference. From the point of view of humans (and also the grand total of all known life forms) planets are better with humans. We are after all the only ones capable of propagating life outside the boundaries of Mother Earth. ;o)

[@glowwurm9365]

This did make me chuckle hard...

[@weaknessisasin6301]

@@veejayroth When man came into existence, for the first time in forever, the universe could think and feel and see and purpose and direction were born amid the black chaos of space. In us, the universe has evolved into a mind and a conscience and a potential beyond that of a thousand super novas. All the mountains and all the volcanoes and all the suns in the universe are as nothing compared to the life and the consciousness and the brain of man. The most powerful sun in the universe could not even build so much as a table; could not think about itself; could not build a microscope to examine itself; could not build a telescope to examine the universe around it. As the most powerful organizing and directing force in the universe, man is the corporeal manifestation of the universe trying to comprehend and control its own destiny. Perhaps we are at once the purpose of the universe and the means through which that purpose is to be fulfilled. If we are the center and focus and fulcrum of the universe through which everything is seen and understood and done, our value and our moral responsibility and religious significance are infinite. If we are the mind and soul of the universe trying to comprehend and control its own destiny, our first moral responsibility must be to preserve and improve the human species because if we do not exist, we can not direct the destiny of the universe. The central thesis of evolutionary ethics is that there is no abstract standard by which to judge the value of human life except the quality of that life itself. If the human race actually does destroy itself, it is of only academic interest that we died fighting for or against. Since all abstract standards of value by whatever name: religion, justice, freedom; are merely human qualities and human creations, without human life, they mean nothing at all. Human concepts or inventions are only a manifestation of what we are, and without us, they are no more important than an empty icon, a hollow imitation, a picture of life. The most brilliant physics, the most compassionate religion, the most efficient politics has no more value than a stone tied to a stick compared to the sacred divinity of the race of man that created it. If the human race exists and improves, they can all be created again but without the human race, the universe is an empty void, an empty anarchy without purpose or meaning. Is there any book, any idea, any religion worth more than the existence and improvement of the human race? No! We created all these things. How can they possibly be of more value than we who created them? If we survive and improve ourselves, we can create infinitely greater in the future. If we are, as evolutionary ethics suggests, the consciousness of the universe that must determine the destiny of the universe, then good is what improves us and evil is what weakens or destroys us. Good and evil are not myths. Good is what promotes social cooperation toward universal human improvement because that increases man’s power, consciousness, control and chances of survival. Evil is putting loyalty to a human construct: nation, religion or politics; above loyalty to preservation and improvement of man because that causes conflict and decreases the chance of survival and advancement. It is not necessary that we all agree to be Christians, atheists or communists. It is only necessary that we recognize the deity that we have in common with all men; the life within our mortal bodies. God, Evolutionary Ethics, and Eugenics James Hart

Loved the video. I had a break-down laughing so much at your comment of: "...everybody would feel like they were blundering around an empty skyscraper, all by themselves. And if someone flicked the lights on in every room on the planet, they'd all catch fire and melt, soon thereafter." Awesome. Thanks. You are a breath of fresh air. You seem to sum up so many of my 'disrupted willing suspension of disbelief moments' I usually get when watching sci-fi or fantasy movies.

[@destiny-1831]

Crazy. In star wars, coruscant has about a trillion citizens, and it has a thousand layers of city and amazingly big structures, so i guess they didnt do the math either

[@j.jasonwentworth723]

Neither Star Wars nor Star Trek are hard SF, because they use double-talk future technologies that may--or may not--be possible (the multiple post-original Star Trek series [set in the future of that world] also had the annoying habit of frequently mentioning new chemical elements such as invidium, calorinium, and so on; the dilithium in the original series was bad enough [while there is an "island of stability" where theoretical super-heavy elements might be possible, it's very unlikely that they would occur in nature, as Star Trek posits]). Arthur C. Clarke's science fiction was hard SF, utilizing known physics, or at least possible new physics that scientists were speculating about (like the quantum drive of the starship Magellan, in his short story--and later, novel--"The Songs of Distant Earth" [in the novel, he listed a real scientific paper that discussed its possible basis]).

[@xeonespydonum4995]

To be fair, the lower levels of coruscant are a hellscape of perpetual night and horrible monsters more akin to fantasy dungeons than habitatable buildings.

[@arturovillarreal2129]

And Star Wars is pretty much Fantasy in space more than SF (although it varies depending on author it still is soft SF)

[@self-satisfiedsmirk5544]

@Harrison Lackenbauer Unless I'm mistaken, I thought that it was really only the last one hundred or so levels of Coruscant that were described as being uninhabited, at least by any recognized sapient species known to the galaxy, and that only the last several dozen were considered truly uninhabitable and described as something akin to a manifested purgatory. The truly hellish aspect wasn't brought into being until after the Yuuzhan Vong conquered and started terraforming it to be like their original homeworld, Yuuzhan Tar, after however many millennia of Coruscant being an ecumenopolis. Regardless, given the potential numbers that can be achieved with the constraints of our real world science that was posited by Isaac in this video, it's obvious that even if half of the lower levels of Coruscant were closed off and uninhabited, there could have (arguably should have) been several orders of magnitude more people living on the planet than the one trillion figure we were given. That's not even accounting for the near magical machines and dubious employment of science that Star Wars has freeing it of various limiting constraints on just how big they can build, how low they can dig, and how many people they can support.

[@swissarmyknight4306]

Star Wars may have scifi elements, but at its core it is fantasy, not scifi. Its a scifi-themed space fantasy setting. The force is straight up magic, the creatures are fantasy creatures. Some of it may play with some scifi ideas, especially in Legends, but at its core it is a fantasy setting.

PBS Spacetime is a pretty fantastic channel and definitely has some overlap with this one.

[@sztellanora]

It's funny that he talks about trillions of people on a planet, whereas simple calculations show that if every woman accessed contraceptives and secondary education, global population growth would stop. You see, no one really wants more people, because it results in more crowding and more competition for the same amount of natural resources, and all the technology that allowed higher population densities were just forced by population growth. (The invention of machine guns, drones, robots, and robot tax makes increasing the number of humans pointless).

[@sosa9754]

sztellanora Contraceptives and education will not stop people from wanting to procreate. I don't really want children myself, but I know of plenty of people that want children. They are also educated and have access to contraceptives. Your arguement doesn't really make sense honestly.

[@sztellanora]

This is not really an argument or a hypothesis, but the actual experience. Study after study shows that access to contraception automatically lowers the number of children per women, and access to secondary education lowers the number of planned children (one reason is because girls with education have future prospects other than becoming a mother). See "UNESCO: Girls' education - the facts", or "Drawdown Project".

Another example of Ecumenopolises that appeared between Asimov's foundation series and Star Wars, and the first one I ever read about, was North Am; a continent-wide city featured in the Gold Key comic book series Magnus Robot Fighter, 4000 AD. in the 1960s. Despite a somewhat dystopian sounding theme about humans becoming too reliant on robots, life in North Am itself was always portrayed in a positive light; much like the cities you have described. It was also probably the first place I ever saw AI as being considered a threat (though there were good robots too).

It was never meant to be a gag, but a natural development of place-name changing over the centuries of increasing technology and population-spread.

Yeah its a bit on interesting juxtaposition with our previous looks at space habitats where the usual constraints are matter and fuel, and space and waste heat are negligible concerns. Here matter is super abundant and power is really bottlenecked by getting rid of the heat. You still get that population cap but its really not related to any sort of privation in the senses we usually get when discussing Malthusian scenarios.

I've watched this video before, but maybe not all the way until the last quarter, where you begin uncovering possible options for preserving Earth's natural flaura and fauna in a totally human-dominated Ecumenopolis. Very pleased, indeed touched, that you've mentioned this concern. Well ahead of celebrating our ingenuity, resilience, and resourcefulness by exploring the potential of all our advanced technologies, there is the immense moral weight of having disrupted innumerable species' habitats in the process. Risk to this unprecedented, spectacular biodiversity on a galactic if not universal scale has far too late become a realization. Indeed, we currently depend on the welfare of the Earth's ability to support us as much as other forms of life.

I've never had a conversation with a rock, but I did have a conversation with a wall once. I hadn't slept in about 5 days, since it was a manic episode, and my manic episodes often left me prone to hallucination and delusions. The wall told me that it had three kids and a bitchy, overbearing wife to take care of, and it had to work 23 hours every day as my wall just to keep things stable at home. I didn't think to ask it what the fuck happened during that other hour of the day, but it wasn't a load bearing wall, so nothing too bad would have happened if it wandered off to take a nap. I imagine that rocks would have the same sort of justification for their continued existence; bizarre, nonsensical anthropomorphizations that can only be "seen" and understood by madmen like me. If I ever miss out on my meds for a while, maybe I'll give it a shot. If I had to guess, though, I'd say that rocks imagine their purpose is to simply keep existing, to remain sturdy in the face of a universe that seems to want to destroy them.

random comment: You made the point that in sci fi they still show ships with cramped interiors even though the interior volume, even if just 1%, should still be huge. My suspension of disbelief tells me that the thing is these ships are SO crammed full of technology, and are such massive systems that the crew space is just eked into a few nooks and crannies. For example a fantheory I ascribe to holds that the replicator you see in Picards ready room is only the tip of the iceberg of what is actually an extremely large and complex nuclear reactor able to control all forms of fission and fussion to break molecules down and build them back up. Sure, over time space faring cultures learn how to build these infrastructures such that the nooks and crannies form long thin corridors. Or think about it this way: Every random persons quarters have a replicator in them right...wrong every fission/fusion molecular assemblor is large enough that if you design it right a person and a bedroom can just be built inside the mechanism itself and then the control panel is just like the tiny little nozzle on a huge machine. Or when the say the holodeck, maybe the literally mean the WHOLE deck is filled with the mechanism to run this one small but technologically advanced room. Just a thought.

[@hypatiaatheiria9647]

Would not be necessary to cramp the interiors of starships - as the key item is mass - thus it would not matter if the space inside were large or small - so the interior could be made to order, other than the mass of air carried. we currently have spacecraft cramped because we have to transport everything out of the earth's gravity well - a future civilisation would likely have overcome those costs

[@jamesbizs]

It's a fun fan theory, but a poor one, as the series has demonstrated many times that a replicator is very small. The size of a replicator is dependent on it's uses. In fact, they had portable replicators. That alone would throw out the entire theory. Sorry for ruining your fan theory :).

[@jcb1832]

joly big comment!

[@jamesbizs]

Any chance you're going to address the elephant in the room in the shape of portable replicators?

[@darthutah6649]

Some sci-fi ships avert this though. In the clone wars series, the Malevolence has an absurdly large space for trains which act as transportation around the ship. Also, ships tend to have very large hangars.

I know this is a random video for such a recent topic, but I have to say I love what you are conveying for our possible future. Multiple angles, multiple options, and bringing up the potential pros and cons to how we may attempt such things. It is pretty awesome

[@testeurglandeur6609]

I spoke to a rock once, it told me it wouldn't mind if we turn his space cousins into habitual space stations, just saying...

[@ShinForgotPassxXx]

It has been quite some time, Isaac. I am glad to see that you are quite busy and are excited and happy to bring more videos about things that hardly get any discussion or content on youtube. I was drawn here because I wanted to know more about the Fermi Paradox but could not really find something, instantly loved that you bring things to my mind that I did not know and that makes me think. Especially with those two Arcologies videos, those are things I never knew and always thought that the future for mankind looks bleak. Kinda like the Hive cities from Warhammer 20k. Liked, loved, told my friends, please more.

[@isaacarthurSFIA]

Good to hear from you again Shin, and yeah I have always disliked that 40k, Judge Dredd, urban hive hellhole look, even if I happen to often enjoy the stories set in such things, it was nice tot take some time to show how that concept is not only not the only way to do that but actually rather unlikely.

[@ChapterFourBand]

Okay so could you possibly have a Rogue Planet/Ecumenopolis that keeps itself heated simply by having lots of people on it?

[@MrStickman1997]

Even with the addition of an atmosphere to warm the planet, it would still be very cold by the time the atmosphere is comparable to Earth. Without a sun, orbital mirrors would not be able to heat such a cold planet...

[@talons7266]

You'd need to import massive amounts of energy to sustain the people somehow, and create some way to retain most waste heat, and likely a lot of time or terraforming if the planet starts out frozen

[@xenozero2128]

So a outer shell, like a pained window. First layer reflects heat back. Other layers insulate, final layers to protect from astroids?

[@emersonpage5384]

First time viewer here. I appreciate you taking the time to talk about speculative options that offer high-tech, future-thinking expansive cities but don't overrun the natural world to do it. Too often people fall into the trap of thinking that preserving the planet's ecosphere and serving the growing needs of humanity are mutually exclusive goals. Speaks to a lack of imagination, I think, to assume that we would have to sacrifice the other life on Earth to support humanity.

[@MatthewCampbell765]

With "near-future" space operas like Star Trek or Mass Effect that involve cultures that reject transhumanism, I believe the main problem they'd run into is how fast humans physically can reproduce, even in ideal circumstances. For example, Trek takes place in the 23rd and 24th century, after an apocalyptic war.

[@YiannisThiakos]

I do not think Mass Effect rejected transhumanism ever. IN ME 2 Shepard is alive due to his implants and in ME3 you are given the choise to make transhumanism reality and is the option that needs the most resourses. IN ME Andromeda the pathfinder has implants, that connects him/her with SAM (AI) in a symbiotic relation.

[@hedgehog3180]

I'm pretty sure that in ME the tech just isn't quite there yet. They can probably make prosthetics that may even be better than human ones but they can't upload brains or anything.

[@JamieFisk]

It depends on what you consider transhumanism. They don't get into the nitty gritty of breeding much in Star Trek, but IVF could be considered a mild form of transhumanism, and they probably have to use that procedure quite often by that point in our future. It's getting increasingly more common for people not to be able to reproduce without the aid of a doctor, and I think it will continue to do so, as time goes by.

[@Janoha17]

@@JamieFisk Star Trek specifically has genetic engineering for 'stronger, smarter, and more capable' humans being banned due to figures like Khan, who also has enhanced ambition and aggression. Genetic engineering also shows up among other species in Trek fairly often. The ridge-less Klingons of TOS were retconned to be an attempt at Klingon Augments, and the most effective weapons against the Borg tend to be engineered pathogens, as seen in "Infinite Regress", "Collective/Child's Play", and "Endgame". And let's not forget the Dominion, whose military and logistics are handled by two modified or engineered species. The uplifted Vorta and the disposable Jem'Hadar.

[@CollinBuckman]

Some recent 40k books, including *The Emperor's Legion* and *Carrion Throne*, have actually said the population of Terra to be in the quadrillions. "I am alone again now. Strange to say that, /surrounded as I am by the quadrillions of the Throneworld/, and yet it is truer now than it has ever been." - *The Emperor's Legion* "Spinoza shivered. The air was as caustic as ever, but so high up it had lost its punishing heat. The humidity was still present, though - /the massed respiratory results of the quadrillions down in their warrens/, those narrow worlds of damp and desperation. She had left her helm locked to her armour, and the clammy gale ruffled through her short hair. Every so often a buffet would catch her, a swell of pressure that threatened to shove her over the edge." - *Carrion Throne*

[@kerbodynamicx472]

A quadrillion on a planet will cause serious heat issues, so I assume this is the population across the whole solar system.

[@Слышьты-ф4ю]

@@kerbodynamicx472 well, theoretically, cooling devices and lenses may redirect the exceed heat to outside... (Since it's Warhammer, it will be focused in one point and used as form of orbital defence) Not enough heat? Add working machines (in the widest meaning of the "machine" possible)

[@1503nemanja]

I just want to say you've got a lot of respect from me from telling down the usual stupidity against immortality and more people. Now with increasing technological capability (but not high enough) and unprecedented difference between the rich and the poor there is a real risk some of the elites might do something stupid out of fear and misinformation. It is exactly this kind of rational, scientific refutal of fallacies of civilization growth, loss of wealth of destruction of the natural world. We can have more people, better living standards and preserve the nature (I for one would support nature preserve areas) but we have to be smart (technology) but most importantly we need to be compassionate of our fellow man if all of us are to make it to the times of plenty.

[@isaacarthurSFIA]

Well said, it's always important to keep a good mix of sober calm reason with a proper sense of ethics when making decisions.

[@5000mahmud]

Aye, we can have a bigger population and still live comfortably even with our current technology.

[@apolloslater8074]

I had the same thought, regarding the Malthusian fear among the elite and possible Final Solution they may implement. We need to change the intellectual climate and show a more optimistic future. This series does that in a concrete, scientific way I haven't seen anywhere else.

[@1503nemanja]

[@marcschawinski3034]

This channel is hands down, better than literally everything on netflix.

[@robertfabiny6294]

The way I understand it the arguments against larger populations would draw on deriving value from uniqueness. If you have one great artist/scientist/composer in your community that person is special and their work will be revered and valued by all. Have a population of containing several million individuals of this caliber and their work won't be valued as much. These arguments run against the addition principle that says that if you were able to keep all thing equal a society will be better off if it had one extra member. But that kind of argument is also a paradox (the opposite of Sorites paradox) - even if adding an extra person to your society is good it doesn't entail that carpeting the entire cosmos with habitats for people is good. However even if these types of arguments were compelling i don't imagine future societies implementing strict birth control measures in response to it.

[@isaacarthurSFIA]

Yeah the uniqueness issue is one I raised in one of the recent videos, Consciousness and Identity, as I can at least imagine with enough people you might have a degree of overlap that made people feel their very existence was impinged on, but I find it a pretty weak line of reasoning, just probable enough to not be dismiss-able entirely. I'd have some difficulty seeing it for populations less than dyson spheres, but its hard to really say.

Take this, what I am about to say, to the end of infinity; I appreciate you. Thank you so much, dear friend. If you will, please answer one question for me to the best to your ability. If space is stretched to the point of infinite density until it tears, how does it instantly heal or go back to normal as a black hole moves through space. Is space not attached, like a sheet where one end is separate from the other, and the black hole just either drags around the same spacetime with it or just swallows the space time fallen within the horizon. If the latter is the case, then maybe black holes, as they grow, will eventually slow the universal expansion to some degree. The root question I'm asking is beyond gravitational waves, does a singularity actually leave a lasting fingerprint on spacetime. Does it slow time and just remove that space from time, thus taking it from our 4d dimension? I have no means of answering this on my own as I am without the means or even know where to start.

Thanks Gregory, I certainly plan to continue for the foreseeable future, there's still so much left to talk about.

[@MrMonkeybat]

The kinetic energy of descending space ships is not necessarily turned strait into heat. If the space elevator or orbital ring has a superconducting maglev rail, then the kinetic energy from the descending space craft can be turned into electricity as it slows powering the ascending spacecraft or feeding into the general electricity grid. Even copper or aluminum coils can turn kinetic energy into electric power with over 90% efficiency but you would need super conductors for transmitting it a significant length of an elevator or ring, but if the stream of ships is continuous it only needs to be transmitted to the nearest ascending ship. So with superconducting mass drivers and orbital rings bacon and sewerage can be sent back and forth between Earth and Lunar hog farms using theoretically almost no energy if the mass going each way is the same.

[@isaacarthurSFIA]

True, and we've talked about recycling that kind of energy before with Space Fountains, but I generally tend to assume a big chunk of people's energy budget will not be agriculture so the 100 Watt human-heat minimum is probably still a good order of magnitude to low. But yeah you could probably get yourself an extra order of magnitude of people importing your bacon :) At that point though, there sheer amount of transport down to Earth and all the orbital farms is basically switching you over to a planet cloud not a classic ecumenopolis.

[@thetayz72]

Right now, with our current societies and technology, we can't sustain tons more people. There's a reason like 1/3rd of the world population lives in starvation and/or poverty. This video is presented from a futuristic perspective and assumes we have nearly unlimited clean energy and advanced automation. Your conclusion from this video should be that it's technically achievable, not that it's currently possible. Huge difference. We don't need population explosions right now unless you want more scarcity, famine, and resource wars.

[@ThatGuyKazz]

Well considering that work on the worlds first fusion power plant has already started and major advancements in robotics and artificial intelligence are happening on a pretty much yearly basis or faster. The technology aspect really isn't that far off of what was assumed in the video. I think that was the point to show that with limited technological advancement we could support many times the current world population. It may take another 100 or so years before we get there but assuming we don't blow our selves up before then we should be good.

[@ThatGuyKazz]

impactofredemption Short version is there is a group called ITER that is currently building a fusion reactor in France. It is still just an experiment at this point and not 100% certain that it will be able to out put enough energy or be able to hold up to the radiation levels long enough for the design to be economically viable. Never the less it is a huge stepping stone and even if the design doesn't meet the expected out put it should provide enough information to give us a good idea of what needs to happen to make it economically viable. You can google ITER for more detailed info.

[@jamesbizs]

+TheKazz you went from " building worlds first fusion power plant" to " building experimental reactor that might not put out enough energy or work for any period of time that's viable".
