>"hard sci-fi">People travel to and colonize planets instead of building space habitatsIt's very tiresome
>>217216726BasedNASA needs to stop trying to go back to the moon and/or pursue mars, and instead put all their federal money into Life Support R&D and building progressively larger and larger space stations. If we ever settle space it'll be in giant Closed-Loop Biosphere space stations made using asteroid materials, where earth levels of gravity can be simulated via centrifugal force for thousands or tens of thousands of residents. It won't be on bone ruining, muscle wasting low-gravity dirtside life on Mars or the moon.
Japan is superior, Hollywood is afraid to touch space colonies because of Gundam.
>>217217013Unironically this is what Bezos wants to achieve long term.
>>217217035Why be afraid? They are cool as fuck in gundam
>>217216726Accelerando was the last hard sci-fi that made any sense to me. We are too physically far away and constrained by limited/no knowledge on what is where anywhere in our local galaxial cluster to even do anything physically in the universe. Old-school "hard sci-fi" is dead solely because the idea of any of that is now obviously retarded. Why put people into space physically for anything? We aren't going anywhere and there is nowhere realistically to go anyway. Maybe the new "hard sci-fi" details virtual worlds where nanobots connect with human consciousness to create a realistic virtual world indistinguishable from the real world, but that's kind of the cap we're finding in what is even acceptable as a realistic sci-fi projection of the future.
>>217216726everybody wants to build something to get to some other celestial body when without FTL we would have to build things we could generationally live on ANYWAYmight as well just skip the "planet" part, then we're free
>>217217013>NASA needs to stop trying to go back to the moon and/or pursue mars...put all their federal money into Life Support R&D and building progressively larger and larger space stationsNASA would have gone the real-world Soviet route of focusing on LEO stations and gradually building up American space capabilities if Kennedy hadn't made a moonshot their policy. So instead of building up NASA's technologies and gradually establishing a permanent and lasting infastructure, we had a short series of lunar landings that were too expensive to keep going indefinitely with the technology of the time. Like Vinland instead of Mayflower
>>217216726Humans deteriorate in space. It's not hard to understand for normal people, unlike for troons like you.
>>217217146>Why put people into space physically for anything? We aren't going anywhere and there is nowhere realistically to go anyway.https://en.wikipedia.org/wiki/Sun#After_core_hydrogen_exhaustionyes it's supposedly billions of years in the future BUT:-it is still a hard "get the fuck out or cease existing" line for humanity, it will erase this planet and almost every trace we ever existed in most of this system;and-there is no guarantee we aged anything right including our starwe simply have no choice, mother is kicking us out of the nest eventually, if we even survive that long
>>217216726nah. the older you get the more you realize this shit is all absolute fucking BUNK.unless you have the Actual Enterprise D waiting for me up there, miss me with all this shit.
>>217217222>The cylinders rotate to provide artificial gravity on their inner surface. At the radius described by O'Neill, the habitats would have to rotate about twenty-eight times an hour to simulate a standard Earth gravity; an angular velocity of 2.8 degrees per second
>>217217244>yes it's supposedly billions of years in the future BUT:the Earth will be uninhabitable and resemble Venus in half a billion years due to increased energy output by the sun
>>217216726Watch The Expanse if you want space habitats
>>217217035>>217217145Supposedly the live action Gundam they're making is going to be largely based on 08th, which I've never seen but as I understand is set wholly in earth, so no space station kino
>>217218415>500 millionso, there's your "get out" bar now, it seems>>217218439for me, it's the Nauvoo>9:1 female:male ratio
>>217216726>>217217013That's fucking stupid, for the cost of some giant useless space station you could restore the magnetic field of Mars, giving it a thick enough atmosphere you wouldn't even need a pressure suit, just an air mask. Then you've basically got a second earth ready for development. Millions of square miles instead of a few square miles.
here's your space habitat kino
>>217218618Sounds gay. They should do Gundam Wing. The best Gundam series.
>>217218688the dust is poisonous or something
They will bring the niggers to space too
>>217218618The first episode, War for Two, is set in space and contains the 2nd greatest RB-79 action in gundam. I quite enjoyed it and would recommend
>>217218688>sun wrecks it anyway >>217218415the fucked up thing is Elon's bullshit about going to Mars to escape sun death only makes sense as some time buying measure; we wouldn't be able to stay there either
>>217218302Radiation and micro meteors will cut holes in you over time.
>>217218747fairly certain the radiation thing will eventually be mitigated by biotech means; there's already supposedly things that eat radiationthe micro meteors would just have to be maintenanced, space is so fucking big though the chances of running into anything in some given area of that size at any given time are very small, so it wouldn't be as bad as you're thinking in general
>>217216726The truth is that there is not, nor has there ever been, true "hard sci-fi". The term is just a goal post that nerds move around when they want to nitpick your science.
>>217218816>The term is just a goal post that nerds move around when they want to nitpick your science.there's a definite vague line between using things that are theoretically plausible if unproven to be possible, and handwaving things off with the tier of "I figured out a way to mix the light and water to make the island move", damon
>>217218747Shields. Next question.
>>217218688mars gravity >1g and it would be easier to build habitats in orbit of Earth than shipping material to mars>>217218747Most proposals say to build it inside a hollowed out asteroid or build a lunar dirt shell around it
>>217218934>mars gravity >1g38% of earth's. Needs to be studied but that's likely enough to live and develop normally, maybe with a weight suit on. >it would be easier to build habitats in orbit of EarthIt would be easier to build in and on a planet's surface, using materials sourced locally. There are already proposals for living in caverns on the moon and Mars, for a fraction the cost of fully man-made structures. We could seal up a few holes and have Martian cities underground within the century.
>>217219197>It would be easier to build in and on a planet's surface, using materials sourced locally.>38% of earth's. you know this isn't a bad point at all, it would be far cheaper all around to launch things off of mars, and it likely would have much of the same mineral and resource content of earth, it would just be a bitch doing all the sourcing and setting upnot sure how capable we'd prove at focusing on even century long goals though
>>217219313>likely would have much of the same mineral and resource content of earthThat's the key. OP has yet to explain the WHY of huge space stations. Why do people go to extreme places on earth, like the Arctic? Resource extraction and research. Well, Mars would be no different. There's not much more research for humans to do in LEO and no resources there either!
>>217216726>It's very tiresomepay the negro, goy
>>217219464>OP has yet to explain the WHY of huge space stations.not OP but we can fuck around on planets all we like; however the real long term issue is shit like this >>217217244 >>217218415stars are volatile, distances are vast, and habitable planets with tolerable enough conditions that wouldn't require some shit ton of work or eat up a bunch of resources to even survive on are probably going to be relatively fewwe would need such craft no matter what regardless anyway to get to some other system than our own, it's not really this thing it's wise at all to try to avoid accelerating mastery ofwe need it, it's the key to our freedom
>>217218688>for the cost of some giant useless space station you could restore the magnetic field of MarsShow your math.
>>217218415reminder that life cycles of stars can be altered with engineering and technology.helium enrichment is what slowly kills stars. we'd need to siphon about 500 million tons of helium per second away from the sun to keep it stable for trillions of years. I bet we will find engineering solutions for this someday. "the sun will explode anyways" is not as doom and gloom as you think.
>>217218744I think Mars is probably seen as just one small step on the road towards intergalactic travel and colonisation.
>>217218688yeah but how are you going to turn the air off when the residents get uppity about eating the slime?
>>217218688Fixing ANYTHING about mars would require millions of times the resources as the proposed stations.
>>217219197How on earth is it easier to build on the surface? The same materials are in space, only now without the industrial problems of gravity and relaunching.
>>217216726>OP>sucks cocks
isnt being born in space like, bad for your body.>people born off earth>racism x10 against us>blow em up and forget we tried
>>217222504That's what the simulated gravity is for. The spinning.And honestly, space will be owned by the first person to get an industrial base up there and a laser system strong enough to clear kessler debris. Then you just detonate a few space stations, and now you have complete domination over space. Earth bound concerns would have to build any response entirely underground, as anything above ground could easily be smushed with any number of orbital weapons.
Hard SF novels that would make good movies thread?
>>217216726
>>217216726humans crave land to walk on.space habitats should only be necessary stepping stones.
>>217217013>one allahu akbar away from vacuumyeah, no thanks
>>217223322that's retarded
>>217222056how would that be possible when helium builds up in the core of the sun?
>>217223681brown people won't be allowed in space.
>>217216726They should live on the ground and have sensors/alarms for space rocks. That means they are ready and have evolved to have a limit of individuals instead of biomass accumulations that still need processing.
>>217219565we have collectively stolen many many times that amount in resources.
>>217218700Nice bait
>>217223273would be depressing anon
Venus is the place to terraform, just send some engineered bacteria to convert the atmosphere and you're good. While that's happening colonists can live in comfy cloud cities shitting off the side.
>>217218744The closest star system is multiple light years away. We will never get there in time
ATTENTION ALL POSTERS,THIS THREAD WILL NOW BE SEARCHED BY THE MARS CONGRESSIONAL REPUBLIC NAVY,FUCK EARTHERS AND FUCK BELTERS,OUT.
>>217224725>cloud cities shitting off the side.we can send pajeets?
>>217216726>hard sci-fi>It's very tiresomeFTFY
>>217224450>WEstole SHIT!The (((Elites))) who pay you useless idiot commies stole everything
Criminally ignored genre of film.What are some of the best hard sci-fis? Like Silent Running, 2001 or Solaris.
>>217226093capitalist pigdog you cannot absolve yourself if you support the system by living in it and being a good little consumer.
>>217218688>>217219197I feel like tarraforming a whole planet and restarting its magnetic field would cost a whole lot more than a 6x20mi cylinder. Plus you still have the issues of different gravity and mars being upwards of a hundred million miles away at any given point. Instead of going there and adapting to it or adapting it to you a space habitat can be constructed to exact earthlike conditions with the side benefit of not needing to escape a gravity well every time you want to travel from there. Or if you're so dead set on going to mars why not just build habitats in orbit of it?
>>217224766Multiple as in 4 ly?That's not that much at all, even if it's way beyond our current tech.Now that doesn't mean there is anything habitable there
>>217217244not my problem
>>217224012programable blackholes that can be set to only suck up specific molecules
>>217224012>helium builds up in the core of the sun?depends on the size of the star, smaller stars (which our sun still is) have full convection, even stuff at the core boils to the surface regularly, so its possible to siphon the "heavy" elements off the star with the right tools.probably some gigantic magnetic induction coil around it or huge orbital mirrors to heat/burn off specific parts of the star.this would involve mega engineering and timeframes of millions of years, but even stars can be "worked" and made more useful. its just another engineering problem and humans are good at this.
>>217224766I think we'll figure it out eventually. We actually have no clue what space is or how it works, and everyone who pretends they know how it works is a pretentious asshole
>>217224766>We will never get there in timewe will just change our perception of time with functional immortality.if you don't have a body anymore that withers and breaks, then even a ten thousand year journey to other stars becomes viable.changing and adapting our bodies to the necessities of space colonization is more realistic than trying to break the speed of light.
>>217224850Fuckin Dustas didn' get da message. Dream of Mars is over, sasa ke?
Gundam thread?Gundam thread.
sure I read somewhere that even spinning habitats don't work for artificial gravity because when they tested it the little gyroscope you have in your ears go haywire so whilst you have 'gravity' it's also like being trapped on a merry go round. the frogposter is actually right about venus, we should build cloud cities. as for kinos I don't really know any modern ones either, Terra Invicta has been my hard sci-fi go to for the past few months though and I think they just released v1.0.
>>217218640>9:1 female:male ratioDamn, i'm about to spin the drum!
>>217227555It depends on the scale. In a small form spinning gravity can make you all dizzy but when you get to a couple miles in diameter it's going so slow you can't even notice
How did Yoshiyuki Tomino predict Jeffery Epstien? I am serious.
>>217216726>>People travel to and colonize planets instead of building space habitatsSouls weighed down by gravity.
>>217227555we're not talking about a spinning wheel on a space station. these habitats will be dozens, even hundreds of miles large, you won't even feel the "artificial" aspect of it, completely earth-like environment on the inner surface. the horizon might bend slightly upwards but thats it.>we should build cloud cities.too bad that Venus has sulfuric acid in the atmosphere at 50 miles up (where pressure and temperature is nearly earth like) so good luck constructing anything up there that won't corrode and fall apart in a few months.
>>217227451Skinnies get the rope
>>217224450>>217226223it's always so funny seeing these commie propagandists outside of their echo chambers, thinking their methods work here
>>217227838>>217228005>but when you get to a couple miles in diameter it's going so slow you can't even noticeI get ya. I still want cloud cities just make the balloons using graphene or some shit.
Spinhabs have a unique selling point, easy access to the greatest intoxicant: zero gravity. Once you've had it you want to retain having it a 5 minute elevator ride away and you can't have that down a gravity well
Hard scifi is for nerds
What is the best Gundam series and why is it Zeta?
>>217228169Habitats don't need to be like this with a hollow interior. That's a huge amount of wasted space that could have tons of levels towards the center.
If Humans right now were going to make some space habitat, it would be hollowing out an asteroid.
>>217228296Oh oh! Gundam did that too! Fuck I would take a non-lethal bullet for Tomino.
>>217226140none of those movies are hard sci-fi because there's no such thing as a hard sci-fi movie
>>217228296The idea now is to spin up gravel pile asteroids and spread it out on a big kevlar cylindrical net. You build what you want on your new inner surface and the cosmic rays can't get you
>>217227480wish sunrise wasn't so scared of late uc because that's when the fun starts
>>217228648There are no objects at absolute zero but we can approach it
>>2172286482001 and 2010 are hard scifi. Hard scifi does not mean "no aliens".
Whitetopia, the final frontier....
>>217228935Would just get a rock smashed into it and all those people blown out into space
*AHEM*FUCK SPINKEKSYOU WILL NEVER BE A REAL GRAVITY WELLThat is all.
>>217228935They all have cancer from cosmic rays.
>>217229314Humans would just evolve to be immune to that after a while. The sooner humans get up there, the better
i never understood the space habitat meme.the whole habitat is just one catastrophic failure away from every single soul living in it from dying, right? meanwhile colonizing a planet and terraforming it to suit human life and spreading the settlements out across different regions mean there's more redundancy (i hope im using that word right).
>>217229268>Aspiring to be a wellniggerYou will never be a true spacer, a starchaser
is it even easier to go into space than to drill into the earth or go into the ocean? both for habitation and mining
>>217229268Counterppoint SPIN THE DRUM
>>217229268weeeeeeee
>>217218695>Browns have all of Earth; still chase whites into space to get their shit.
>>217229645afaik it's one of those things, like green energy, that takes a huge investment to say put actual industries into space but once it's there and established it is actually far superior to digging up everything on earth and all the pollutants and shit that come from that.
>>217229645The idea is you leave the planet. Basically a great extinction is happening right now partially due to mankind partially due to a couple random things. It happens every so often. Massive stretches of Russia could support lots of people but the issue is humanity is converting alot of matter to energy blah blah. 500 years the planet won't be able to support much human life if it's modern.Basically we have to spread out or we kill each other with ever increasing power and control. Eventually some rich guy will probably blow up earth out of spite
hard SF people are the biggest faggots on earth
>>217218695I liked the designs and hated the open borders kalergi plan story
> When seen from outside, planets are burial sites, where precious minerals are interred. By digging through the earth’s mantle, for instance, all the way down to its interior end, 3,000km beneath the surface, one reaches a high-pressure iron-nickel deposit over 6,500km in diameter—a planet-vaulted metal globe roughly 160,000,000,000 cubic kilometers in size, doped by enough gold and platinum to coat the entire surface of the earth to a depth of half a meter. To a moderately advanced off-world civilization, pondering the practicalities of its first planet-scale demolition, leaving this buried resource trove in place has a robotic-industrial opportunity cost that can be conservatively estimated in the region of 1.6 x 10^23 human-level intelligences, a mineral stockpile sufficient to manufacture a trillion sentient self-replicating probes for every star in the galaxy (Even ardent conservationists have to recognize how tasty this morsel will look.)
>>217229489Terraforming is the meme. It's so much energy and work to be impossible. The movies pretend it's "just turn on a machine, pump some air out, it'll be done in a few years, eh no big deal!" And that it can be done to dead, lifeless balls but not Earth for some reason. The space habitats can at least be made as safe as possible. They don't actually need to be completely hollow with only one layer between everyone and space
>>217218695Probably the softest scifi ever made. The damn space habitat is open to the vacuum and they have magical healing pods that fix people in seconds and cam be flown down to give free healthcare to the world in minutes
>>217217013>>217216726bad idea unless you want to get space autism
>>2172282100080
>>217218700Wing is shit
>>217230372>The damn space habitat is open to the vacuum Plasma window nigga https://en.wikipedia.org/wiki/Plasma_windowThe thing was far too close to earth though, atmosphere drag would get it
>>217216726We can do it now so likely already been done many times over.https://www.rochester.edu/newscenter/cities-on-asteroids-it-could-work-in-theory-543862/
>>217228169>>217228270The windows are wasted space too. With modern lighting and materials you could get away with one small or no windows and get way more internal space
>>217216726Maybe one of the many successor species (or genus, specifically) to humans will have the ability to drastically speed up and slow down their perception of time, or be able to go into mental stasis, such that the scale of traveling around to nearby star systems becomes more feasible.They'd still have to make peace with the drastic amount of changes that happen between each trip. For them it could feel like a time skip, or feel like going through one million external seconds per internal moment, rather than 1second per 1 moment that we current humans experienceThey could be non-physical altogether, or be able to beam their consciousness to different jump clones on standby lightyears away, but that to me is unsatisfactory
Okay... You don't need to use ring. You'd use a 600 meter line with a counter weight and a building on the other end where people live. Jesus fucking christ what happened to Gen z>>217228169That's incredibly stupid design with a shit ton of wasted material weight and space >>217230833....You can't build small spinning rings. The ring would need to be at least 600 meters in diameter and you can't put anything living or liquid or gas inside of it while it spins Tell me you know why and this is bait please. I am not explaining 4th grade math.
If Gen Z doesn't know why a space cylinder has to be at least 600 metersThey are fucking retarded and their math is worse than ours was in 4th grade. There is no fucking way you idiots don't know it. I'll give you 3 minutes and I know what the ai says
You stupid fucking bastard how do you not know this shit. You build it under thar and want any kind of gravity everyone will be vomiting and or stroking out eventually Tell me why. Tell me your generation isn't that fucking stupid and you know why. Tell me you idiots won't try to design something that will literally kill people in a couple of hours if you go to even half g. THE FUCK CORIOLIS EFFECT YOU STUPID FUCKS JUST ONE PROBLEM
THAT'S WHY YOU DONT BUILD FUCKING CYLINDERSITS SCI FIYOU USECOUNTER WEIGHT LINE THEN BUILDING JESUS FUCKING CHRISTYOU ALL ARE SO BADLY EDUCATED YOU DONT EVEN REALIZE THAT RING SHIT IS SOFT SCI FI AND MAKES NO SENSE
The O'Neill cylinder was proposed in 1976 and it's predecessor, the Bernal sphere, in 1929
Realistic ones might resemble a set of banded toruses, nested one inside the other Russian doll style. The interior height of a torus might be 100 meters so you get the 'outside' feeling
>>217231367That's so crazy it just might work
i liked knights of sidonia. how hard is the sci-fi there?
>>217229489>he whole habitat is just one catastrophic failure away from every single soul living in it from dying, right?these things will be dozens of miles large at least, probably more. even with a catastrophic hull puncture where you have a hole several feet in size, it would take weeks for all the air inside to siphon out.there will be entire ecosystems inside and the land area will be larger than most countries on earth. the entire thing has mass beyond mountain ranges on earth, it takes a whole lot of energy to move them or alter their location, this won't happen by accident.there is no accident that can happen that could immediately put everyones life inside in danger, everything will have months or years to fix, even if it already happened. its practically an entire planet anyways, just with a different geometrical layout
>>217232324Why would you think the puncture is feet wide? Get hit by an asteroid or attacked by a nuke and it would be miles wide plus a possible exit hole on the other side. That also doesn't account for the edges of that puncture losing strength and starting to rupture outwards tearing along the axis like many pressure vessels do when there's a breach
>>217232383This man is delirious. His soul is obviously weighed down by gravity
>>217218640I'm glad that shit got flung into a rock.
>>217232943It didn't though.
>>217233380Fuck, I'm still not done with the book, they were just discussing doing it.
>>217217013I'm not interested in space, but closed ecosystems are neat. I wish Biosphere 2 was a critical success.
>>217228169i don't want to live in a gay spinning cuck chamber, i want to walk alien worlds and fight space dinosaurs and shit
>>217233541It's all barren rocks. We will have to create the alien worlds and space dinosaurs ourselves.
>>217223273Nobody writes near future colonization sci-fi like this boomer. His novels have all sorts of cool tech like ships being built in space by nanomachines which gather their materials from nearby asteroids. And skips a metric fuckton of melodrama between the characters that other authors would plunge right into. In a Ben Bova novels the characters are either - having sex (there's alot of sex), working together to defeat an anti-space expansion terrorist (lots of those) bent on wrecking whatever colony is being set up, or working together to survive whatever space disaster is currently happening. The first six or seven novels expand outwards from earth like Space elevator novel, then moonbase novel, asteroid belt, mars, etc etcThey're great
>>217233674Does it get beyond the solar system?
>star trek has convinced everyone that we'll be flying to a thousand new stars in a hundred years>in actuality, over the next thousand years, we'll probably still be in this single solar system
>>217234102Yeah, he did a few of those, sent one of his major characters on a journey to the next galaxy. But I think he retired as a writer around that time. The guy is like 70 something or dead by now.
>>217224725>move closer to the sun to live in orbit of a planet with no magnetic fieldEnjoy your dead. May as well shit O'Neill cylinders around Earth gundumb style at that point.
