Terraforming other planets would be astronomically more challenging than fixing our own planet and we don't seem to be able to get our shit together to do that. Even if we are capable of terraforming other planets, it would take many centuries at minimum. O'Neal cylinders are far more likely to work once we start industrializing the moon.
Bonkers question. Can't even figure out living on Earth sustainably and you want to talk about doing it without gravity, an atmosphere or an ionosphere?
I don't think capital can sustain projects of this magnitude. Space is too harsh of an environment for delulu. We can hardly grapple with the idea that our actions on earth have consequences because of our condition. I like space stuff and I even like to create designs of starships, but I don't think we're in a position to reach for the stars just yet. Even if I'm wrong, we can't allow space fascism get started either. There is probably life out there and if space capitalism finds them, they'll try to pull another indigenous genocide and invent new forms of xenophobia to justify it.
None of our problems are technological. We have massive people problems. Building a new billions of dollar machine or trillions of dollar space station isn't going to disrupt the imperial core. The Gray Techno Fash won't suddenly become humanists because space.
Space life can be fun to think about, but techno futurism is a liberal fetish and tends to result in liberal fantasies if you don't decolonize your mind.
If we can't manage to keep Earth's ecosystem thriving to support us, we certainly won't be able to create a new self-sustaining ecosystem elsewhere. And without that, there's no chance of any non-Earth settlement being able to sustain a healthy human society and culture long-term.
Without some serious (currently impossible) terraforming, Mars colonies are limited to deep caves or heavily shielded buildings, no outside to relax, nowhere else to go. Have a look at the list of crimes in Antarctica, a similar situation where people are stuck together, that's not a good environment for mental health, and it will be worse farther away. A Mars colony (edit: or space station) owned by a private company will be a corporate prison, the inhabitants are 100% dependent on that company - who would voluntarily put their lives into the hands of the whims of some narcissistic hoarder with no empathy or regard for workers?
I'm not sure that fitting Earthlike habitats in giant spaceships would make sense without limitless exponential growth. Wouldn't it be more feasible to put something on the surface of a planet?
No matter how advanced our technology gets, we are not going to get around the basic constraints on energy.
I'm guessing B will happen first, just because we have so much more control of the environment, but we're still so far away from either one... Maybe I'll get to see the early stages sometime in my life.
All of the above. But start with cleaning up this planet. Build better / more sustainable and more diverse communities and energy production. Build arcologies in the arctic, deserts, oceans. Those are good “practice” for building the same off planet.
How to survive in space: Develop ways to survive in space only first. Once you manage that all the other problems are trivial compared and you don't have a single point of failure (aka our planet) anymore. Isn't that obvious?
A quote attributed to a few people, Heinlein and Pournelle for two, "If you can get your ship into orbit, you're halfway to anywhere." Both space and planets have shared and their separate problems to solve. In my head I prefer the image of most populations moving into habitats in space, customized to their preferences, with smaller settlements on various bodies for their own purposes. In my realistic view I don't see us getting that far before we get bogged down with all the problems we've created on this planet. The window to a permanent space civilization might have already shut. A sad thing, as a 70s kid I grew up convinced we were full speed into some version of what scifi had sold to me.
Neither. There's plenty of room and resources here on Earth. I think it's fine to do space exploration and even have research bases on moons and other planets, but I just don't see the imperative for colonization.
After reading A City on Mars by Kelly and Zach Weinersmith I think a O'Neill Cylinder spinning spaceship for artificial gravity type is more achievable than planarity colonisation.
But the main point of the book, and I am fairly convinced of the more I think about it, is that it is a lot of effort and risk for not a lot of gain and we are entirely unprepared for space colonisation.
Until we are able to travel way faster than what we can do now, I think it’s more feasible to build in space. Lots of implications for long term effects on human bodies though. Most ideal is a wormhole to an identical planet to earth so humans won’t need to adapt.
I don’t think space habitats any significant distance from Earth will be possible. Mitigating the increased radiation will be tough enough just trying to get to Mars, much less trying to stay in space out that far. At least on Mars we can hang out in old lava tubes or something.
Huge sci-fi lover here. But at the same time, colonization of space for humans is possibly impossible without avatars. The human body evolved here, and it's a vessel that works here the best. To colonize other worlds, it's more economically viable to send machines, create biologically synthesized new species (taking dna from local species there), and then transfer consciousness to them. Similar with Avatar, but without having to have the spaceships arrive in the planet full of humans. Humans remain on earth, and they project their consciousness somewhere else, in an instant due to entanglement.
c) Move life underground and leave the solar system on Earth as a spaceship. It would be the biggest achievement of humanity if we move the planet out of this shit hole and be able to do it all together.
