uj/ If terraforming is possible, why not just terraform Earth?


Dragon_Of_Magnetism

uj/ Because let’s be honest, building cities on other planets is pretty cool


janamichelcahill

That's Alien Nation the movie.


skeetsauce

One idea is exporting all our manufacturing to Mars and purposely emitting greenhouse gases to terraform it’s atmosphere to be more earth like.


janamichelcahill

Mars was once a Greenhouse, and then "God" destroyed it; so the Garden of Eden, the perfect greenhouse, was on another planet!


[deleted]

But why Why Mars


skeetsauce

This is extremely sci-fi for the record. But the idea is Mars already has an atmosphere that could in theory be terraformed over hundreds of years of polluting green house gases. Stop accidentally polluting Earth and start purposely polluting Mars and in with enough time, two nice planets to live on.


[deleted]

>Mars already has an atmosphere what atmosphere >two nice planets to live on But why Mars? Why not Venus?


[deleted]

Because Venus is stupid and hot and tiny and I hate it because it called me a mean name >:^(


[deleted]

Mars is stupid and cold and even tinier and I hate it because the only thing going for it are deadly dust storms Also it's further away than Venus Wtf is this hyperfixation with Mars??


scarydan365

Venus is the hottest planet in the solar system, and its atmospheric pressure just devastates everything we try landing there. It’s a terrible choice. It’s such a terrible alternative to Mars that I’m not sure if you’re trolling.


[deleted]

Who said anything about landing? The temperature of the Venutian atmosphere is around 40°C, way better than the -100°C you get on Mars. So in theory, humans could live in floating cities in the atmosphere of Venus which is way more rad than living in some dank hole in Mars. Also there's - a thick atmosphere to protect against cancerous radiation - a gravity similar to Earth's - no dust storms - cool chemistry shit - closer distance to Earth But on Mars, you can - touch the ground I guess?


kelvin_bot

-100°C is equivalent to -148°F, which is 173K. --- ^(I'm a bot that converts temperature between two units humans can understand, then convert it to Kelvin for bots and physicists to understand)


[deleted]

I think Mars is a stupid idea as well. Ideally we should start with the moon/orbital habitats and refineries for space resources. It all has to do with the cult of Elon and his brain dead supporters.


[deleted]

go to moon then to venus send robot to titan for shits and giggles


QtheDisaster

Well, I'm more of a Red Faction kind of guy... Just saying and I would say that colonizing Mars was a popular concept before Elon Musk


Ok-Mastodon2016

uj/ because we need to have an off-earth story rj/ because earth's reasources were all dried up and it was all polluted! (even though we apparently had enough resources to construct a massive fleet of massive ships with either enough fuel to get to another solar system or a new extremely potent and powerful form of energy)


Chipsmc3

The over pollution being caused by the mass factories necessary to build the off-world ships lol


Ok-Mastodon2016

funny enough that's kind of what happened in Firefly's lore, but that's just because building the ships became top priority


fatalityfun

actually realistic, there’s probably a point where saving Earth is possible but would cost more energy than killing it and moving planets


Gen_Ripper

Happens in *The Three Body Problem* series, but that’s for a war fleet and due to necessity.


GilbertGuy2

I mean, technically we are doing that right now


Penguinmanereikel

You can’t terraform new resources, like minerals onto the Earth. Well, you probably can, but probably not while there are people living here


benmaks

UJ/ Totally hypothetically, it might completely demolish what already is there.


nanotyrannical

The idea is that we don’t have to fix the problems we eventually cause because we can always terraform another planet. We can treat the terraformed planets the same way we treated Earth and then just not bother to fix them and leave in several centuries


Ozark-the-artist

uj/ Most bodies here are extremely uninhabitable and it might be easier to colonize exolanets, as long as there is FTL travel.


personalistrowaway

uj/ a loose scifi setting where ftl travel is impossible would be really interesting though. A fully terraformed solar system with floating cities on venus and orbital habitats abound. Maybe other solar systems have been colonized but they are treated like how the romans thought about China. Getting information rarely and only very occasionally sending diplomacy, and the veracity of even that is disputed.


Bonible

This reminds me of Rimworld (Game). Humanity doesn't develop FTL, but they develop cryptosleep and an engine that can slowly, but steadily, go through long space trips to other planets, in the span of years. The human race is scattered throughout the galaxy, aswell as it's cultures.


OctagonClock

Terraforming Venus is multiple orders of magnitude easier than floating cities on Venus


Silvadream

terraforming mars can't be too difficult. Otherwise people wouldn't play it.


dr_prismatic

ive always heard the soil is toxic to a degree that removing it would be like resurfacing the entire planet with new dirt.


OctagonClock

It's full of chlorine which does not tend to agree with most life


GI_gino

But imagine how clean the pools will be


shivux

Just mix it with sodium bro. Boom! Salty Martian seas.


Silvadream

The joke is that there is a game called Terraforming Mars


dr_prismatic

which ive played before.


Silvadream

I haven't


CodDamnWalpole

Not really. The upper atmosphere of Venus has an atmospheric pressure and gravity roughly equivalent to that of Earth's, with a higher atmospheric density. That means if you fill a balloon with a breathable air mixture on in the atmosphere above Venus, it'll float on its own and even provide lifting force. Look up Venus aerostats, they're pretty interesting.


Psychological_Fox776

That’s why we have O’Neil cylinders (air in a giant spinning tin can)


jay_22_15

I feel like this is a Star Gate reference that I'm not getting.


ST4RSK1MM3R

It’s a reference to the Lorax


Kilahti

There was a real person by that name who came up with the concept for a book in 1970s. Duckduckgo it.


HighTideIndustrial

You still use duckduckgo?


Pashahlis

Why not?


HighTideIndustrial

That controversy regarding Microsoft trackers.


Pashahlis

Huh never heard of it.


Ok-Mastodon2016

well I'm mostly talking about stuff like Trigun, I only know a bit about it so take what I say with a grain of salt so humanity fucked up Earth but don't worry they got these Interdimensional plants that give a lot of energy and allow them to terraform worlds and whatnot, but instead of terraforming Mars or Ganymede or Europa or smth they decided to freeze everyone and go to another solar system to another planet that still needed Terraforming, admittedly the name "Planet Gunsmoke" is pretty badass but it still doesn't make much sense to me


Ozark-the-artist

That's a much different setting. Your meme doesn't mention magic plants.


Ok-Mastodon2016

but it does mention Terraforming, which the plants are used for


DROSS_79

What about orbital colonies and megastructures? Why don’t we just use the matter of those uninhabitable planets to construct giant space stations that are habitable. Honestly way more feasible than FTL


RobbLCayman

It's important to me for accuracy's sake that the story takes place on planets that can be filmed in Georgia, with little-to-no environmental CG budget.


HighTideIndustrial

You mean, Venus and Mars? Venus is a carbon copy of earth, we just need to get the atmosphere off. Mars is a radioactive hellscape, but it still gets a earth similarity index of 0.70, meaning it's in the top 20 of the most earthlike planets known to man.


Ozark-the-artist

So easy to get rid of an atmosphere... For real, they're not as inviting as some people say. Mars kinda, but still overrated.


HighTideIndustrial

Well, we've got the time. the freezing of the atmosphere takes 250 years. Shipping those ices away takes just as long. That's 500 years until you can expose the world to the sun again. From there on its about 150 years to get the hellhole to a state where a human can survive on it without special equipment. By those 500 years, you are just going to have arrived in Centauri and set up your orbital infastructure. so venus is a pretty good choice. mars in comparison is a radiation- ridden, chlorine soaked hellhole, which would require far more effort. maybe less time tough


Filip889

How the fuck are you going to freeze an atmosphere?


ThisUserNotExist

uj/ Cover the sun rj/ Cover the sun


HighTideIndustrial

A Orbital shade, essentially a comically large tinfoil, located in the l1 point. Assuming we are shading the entire planet, It would take 200-300 years. Extracting the material is a non-concern, since it won't even be a percent of Earth's yearly production. You'd probably need far better automation, since you'd have to do it on a low-gravity body, and even then have absurd launch capacity, even more than a space elevator could provide, but it's still a simpler task than building a interstellar arkship for half a million people. Personally, I don't think we are ever going to get off earth in a big way, but if we do, it probably wouldn't even take up 0.01 % of our population to do that.


Filip889

Well, yeah, but wouldn t building underground cities on mars be a way easier job? Much easier than all of this. But realistically the arks may be a way better idea, if we ever manage to figure out anti matter reactors, well compared to terraforming Venus anyway.


HighTideIndustrial

Why not both? And when we are already at it, why not dismantle mercury to make a Dyson swarm (other than that it is probably a suicide technology, in my opinion)? And why antimatter? We don't power those arkships with kugelblitz black holes, or with regular fusion. Heck, we don't even know if antimatter is actually a thing.


Filip889

Hasn t anti matter been already discovered? With the large hadron collider? Also nice Umbrella Academy reference


HighTideIndustrial

I haven't heard of that,so it's probably a quite recent discovery. Also, never heard about that series. Can you please tell me what you thought was a reference?


Haw_and_thornes

My scifi world has everybody live on moons around the planets of our solar system. The Earth's all fucked. Idk if it's realistic or not, I just like all the old Latin names for the moons.


Ok-Mastodon2016

That sounds cool can you tell me a bit more?


Haw_and_thornes

So, the whole thing is a massive stretch to create a black and white cyberpunk world. The capital is Europa, which was colonized into essentially a massive concrete water-cooling rig for the EVE system (dystopian government controller). Europa already had a bunch of ice and water, so it made sense. The Eve protocol uses old movies as its 'training data' on human nature, but the only movies that survived the Earth's destruction weren't saved digitally, but were antique enough to be preserved. So... Film noir, predominantly. Eve went and banned Color adverts, and so the brightness on the monochrome billboards is turned up really high. The MC, a wannabe private eye, fucking hates them because all the shifting conflicting light makes it difficult to take photos of cheating husbands.


Ok-Mastodon2016

that's pretty creative!


Haw_and_thornes

Hey thanks! It's called Neon Noir. It's gonna be an old style radio drama, but with more Vangelis synths.


Doubleplusregularboy

Apparently I'm into this


DROSS_79

What are the colonies like? Do they live in the natural gravity of the moons or do they spin them to create additional gravity?


Haw_and_thornes

The gravity on each is roughly equal to Earth's, through various means. I looove what the expanse did with handling how our bodies would likely fail, given long term exposure to different gravities. It's so well thought out, and incredibly compelling plot wise. But I want to do a 'planet of the week' type thing, so it didn't make sense to go incredibly hard sci-fi. Esp. because thematically the world is noir. Just happens to be set in space.


DROSS_79

If you’re setting things far enough into the future, they could also hollow out the moons and throw earth-massed artificial black holes into their cores to give them earth gravity


Haw_and_thornes

That's what I did for Europa, the capital. On Triton, which is a Casino Ice Planet, it's only artificial grav for the casino itself. And then mars I let just be a little lighter.


DROSS_79

Sickkk, dude. So what’s going on with earth? I’m sure it’s not mentioned in the story much, considering it’s set in the outer planets, or is it straight up gone or something?


Haw_and_thornes

I open with "Past Earth's desiccated remains, past Mars' war torn craters, the moon Europa slowly circled around Jupiter." Basically the Neo-Centrists kept exporting water once Earth had become unhabitable, leaving it a husk of a planet. Mars is an automated military complex, in eternal war with itself. People just try to survive the endless drone strikes.


DeviousMelons

I absolutely love when they ruined earth and decide to go to somewhere far off and terraform a lifeless rock instead of yknow... Terraforming earth.


scarydan365

Because you can aggressively terraform a lifeless rock eg nuking it, dropping massive ice laden asteroids on it, causing global warming or global cooling by lacing the atmosphere with stuff. You can’t do that on a ‘on its way to be lifeless rock but isn’t yet’ that has billions of people on it. Sometimes it’s easier to build a new house than renovate an old one.


Quardener

My scifi project takes place on 8 planets (and their moons) all of which are in the same solar system. Felt pretty unique in my mind atleast.


Ok-Mastodon2016

that's fai-... it's our Solar System isn't it


Quardener

No haha. I don’t see how one would colonize the gas giants.


Ok-Mastodon2016

well there's these things called Moons which you mentioned soooooooooooo... Just saying colonizing Jupiter's moons is often thought of as Colonizing Jupiter though in theory I guess you could build like a big shell around Jupiter's "surface" or a massive ring at its equator


Quardener

Hmmm true yeah fair enough. There is one gas giant but it’s at the farest end of the solar system. 8 planets and a couple dozen moons, no one’s really seen the need to live above a gas giant.


Ok-Mastodon2016

fair enough


shivux

“Surface gravity” (gravity at 1 bar of atmospheric pressure) on most gas giants isn’t all that high. Uranus’s is lower than Earth’s, and Neptune’s and Saturn’s are only slightly higher. If you had some kind of floating cloud cities in their atmospheres, the average person could probably live in them no problem.


Quardener

Yeah but I mean, what’s the point? You’re spending who knows how much fuel and energy to stay aloft and are constantly at risk of disaster if something fails. Why do that when you could instead live on a solid rocky planet.


planetixin

Why can't we terraform Earth first?


Gen_Ripper

Zoning laws


SyncOut

Imagine a planet full of single-family suburban homes


Gen_Ripper

I was just telling my spouse to imagine car dependent suburbs in O’Neill Cylinders.


DeviousMelons

Truly the worst of all things, space NIMBYs


Ok-Mastodon2016

because rich people


32624647

Terraforming is for chums. If you have good enough life support tech and you enhance yourself with biotech and/or cybernetics, you can live in "inhospitable" planets just fine.


Gen_Ripper

*Emancipation* ending for Beyond Earth.


gyurto21

My sci-fi is set on another distant Earth-like planet because all other colonies either died or struggle to survive without the support of Earth where civilisation died out almost instantaneously.


Ok-Mastodon2016

sounds neat


gyurto21

And if somebody has the question of "why don't they just go back to Earth?", well because they don't know it exist. It was forgotten.


ImOkNotANoob

why don't they just go back to Earth?


Working_Word361

it was forgotten


[deleted]

Uj/ wasn't the firefly set in a distant solar system rather than ours?


Ok-Mastodon2016

yes, but they at least had enough sense to colonize all of it, and it's a good system to do so due to size and numbers, it has 5 main sequence stars, 7 protostars, 7 gas giants, 3 separate asteroid belts, 75 terrestrial planets and 149 moons


Gen_Ripper

GOATED system. Has anyone calculated the possibility of such a system existing?


HighTideIndustrial

Note that theese are the ramblings of a idiot on the internet, and not everything I say must be correct. Do your own research. There are two confirmed 7-Star systems, AR Cassiopeia and Nu Scorpii. 8 star systems are probably also possible,I doubt the viability of any larger system(unless artificially optimized). I have heard people who say that planets around polystar systems are rarer, because the extra stars also need matter. However, I've seen just as many people saying that this isn't really the case. I don't know what's true. I believe there have been 4-star systems with planets found, and I know for certain that there are trinary systems with planets, as seen in the alpha centauri system. How would such a system look like? First of all, communication time would be far less, but it still would take it's time. Alpha centauri ab is about 2 light months away from proxima. However there are people who think it's a binary system with a visitor, and it's on the very edge of being gravitationally bound. But a 7 star system probably still stretches a light year, leading to comm times of a year. As for how many planetoids, assuming multiple stars don't inhibit planet formation: Our solar system has 4 terrestrials 2 gas Giants 2 ice Giants One object of 1-3 mars masses, according to estimates working with probability calculations Moons: About 200, with Luna being the largest And for dwarf planets: Note that most of these are not confirmed to be in hydrostatic equilibrium, but are thought to be. Five of them are recognized to be: 10 dwarf planets <900km 17 dwarf planets <600 km 41 dwarf planets <500 km 62 dwarf planets <400 km 622 dwarf planets <200 km Minor planets About a million As for red dwarfs, we know that one can have 7 roughly earth mass planet, however much more tightly packed, as seen in Trappist. From wega we know that massive stars can have debree clouds. I've seen estimates of a hundred earth masses for Vegas debree cloud. Based on that, you schould be able to make your own estimate. Edit: But if you really want a planet based empire of a hundred worlds, having 100-200 terraformed planets in that system is probably possible, especially since you don't need to be in a habitable zone for terraforming if you use solettas.


CoffeeForMeThanks

The largest moon in the solar system is Ganymede, not ours


HighTideIndustrial

Thanks for the correction, I don't know why I remembered that wrong.


CoffeeForMeThanks

The moon is the largest in the solar system relative to its parent planet, that might be it


HighTideIndustrial

Probably.


Pashahlis

>Moons: About 200, with Luna being the largest >Minor planets About a million Wait what???


HighTideIndustrial

Yeah, our solar system got about 200 moons https://solarsystem.nasa.gov/moons/in-depth Also, as another person pointed out, Luna is not the largest. And minor planets, with the exception of dwarf planets, are not all that impressive. https://en.wikipedia.org/wiki/Minor_planet


Pashahlis

> Minor planets include asteroids (near-Earth objects, Mars-crossers, main-belt asteroids and Jupiter trojans), Ah that explains it.


HighTideIndustrial

Added a edit to my comment.


Ok-Mastodon2016

well since it looks like [this](https://firefly.fandom.com/wiki/Maps_of_the_%27Verse) I doubt it could


Penguinmanereikel

And Cowboy Bebop


Ok-Mastodon2016

Earth wasn't ruined until after they started to colonize space though also am I the only one who feels like it should be set further into the future? it's an amazing show but I feel like with how much there is in the Solar System, and the [Used Future](https://tvtropes.org/pmwiki/pmwiki.php/Main/UsedFuture) vibe from the show, the Bebop looks like it'd be older than the Space Era in the show


Pashahlis

The reason Earth is kinda destroyed is so sad. And then the crew kept the information to themselves, too. So nobody will ever know the truth. Really sad tbh.


Ok-Mastodon2016

what was the reason again? I've seen the whole series but I don't remember them bringing up the real reason Earth got turned into a shitshow


Pashahlis

No it was brought up. The company built a faulty gate on the moon or something and that gate exploded.


Ok-Mastodon2016

I wouldn't call that... sad unless it's about the evils of Capitalism, then yes I agree I did know how the Gate thing happened but the way you worded it made it sound like it was different


Pashahlis

Its about the evils of capitalism yes. But the sad thing is that this was successfully covered up and when the crew found out about this they kept the information to themselves. I am not sure what the reason was again. It was some deal.


Ok-Mastodon2016

fair enough


davidmcdavidsonson

Ten Thousand Years Later...


Ok-Mastodon2016

they ded


HopefullyThisGuy

/uj I just did both. Send a few waves of colony ships out across the stars to other habitable exoplanets while continually attempting to make other planets in Sol more habitable via terraforming.


Ok-Mastodon2016

sounds cool!


TheEekmonster

I think it would not be feasible short term. It would take thousands of years probably. It would take shorter time to genetically alter us to fit into an alien atmosphere than the other way around.


Ok-Mastodon2016

true, but if you want an interplanetary society you probably want people to be able to breath the same air and stand up in the same gravity


TheEekmonster

If we are talking about a 'far fetched' hypothetical reality. I think that would never be the case. If someone would colonize a 0.7g planet, in 3 generations you would have a group of people that will not exist comfortably in 1g. Being able to breathe the same air, even star wars with the softest of world building have several species of aliens that are continually forced to wear rebreathers because no one breaths the air they do. In an event of a human galactic empire, within 3 centuries we would have new breeds of humans. Even if we find planets with similar enough atmospheres. An alien biosphere could influence new inhabitants enough to create a divergent. Just from eating different food and living under a new sun. And even with a new kind of gravity.

BroceNotBruce

If you can support your passengers on a generation ship to reach the new planet, can’t you just make a space station and harvest resources and energy you need from asteroids, stars, and planets?


janamichelcahill

The Boss needs to watch the tv show "Alien Nation" and watch the Final Ending. He will get why he's wrong.


Ok-Mastodon2016

that was a show? I thought it was movie so what is the ending?


janamichelcahill

It was both a show and a movie. The movie ended with Earth being spared from annihilation for keeping the Alien in custody and allowing the Alien to colonize Earth. In the show, the Aliens were hunted because on their planet, they were escaped criminals and Earth was saved from handing them over to be destroyed.


Ok-Mastodon2016

that's cool I guess


MadChild2033

Scifis always annoy me when they can terraform planets but never bother with earth. We have more than enough empty shit where humans can't live already


HighTideIndustrial

But those areas still have their own unique biosphere they might want to preserve


MadChild2033

like fucking deserts? or most of asia, australia and africa? i don't give a shit about logic and realism, i just want a green africa with proper water access


ST4RSK1MM3R

Looking at you, Stellaris. And most Sci Fi work. The most any of them will do is colonize the moon like 30% of the time


Azimovikh

I just do paraterraforming, make space habitats, or make the humans modify the fuck out of themselves to live in the other planets of the solar system.


BroceNotBruce

If you can support your passengers on a generation ship to reach the new planet, can’t you just make a space station and harvest resources and energy you need from asteroids, stars, and planets?


Ok-Mastodon2016

that would actually make a great premise! like r/Everexpandingbunker but instead it's an Ever Expanding Spaceship


BroceNotBruce

Well really the best option is probably multiple smaller habitats forming a dyson swarm


Ok-Mastodon2016

I guess so that'd be awesome actually!


RommDan

Meh, building millions of O'neill Cylinders is way cooler.


kachet11

on these theme: I really love how space age described in Schismatrix. It have just solar system colonized, but in there so much groups of peolpe beyond or inside main two


MannfredVonFartstein

I mean, what‘s easier: travel to another solar system or generate and funnel enough energy into a planet so it can maintain a functioning magnetosphere. Then we also must consider what is easier: a planet with a mass similar to earth or a differently sized planet whose gravity completely fucks with the human species


Filip889

Isn t it kind of impossible to terraform worlds that don t have the conditions for life? E g, outside of the goldy locks zone, too small to maintain atmosphere, to heavy to alloe humans to walk on them etc?
