Our own dung has all the needed microorganisms it needs to break it down if left on an alien planet that has different biology. Given light and some type of O2 in the atmosphere.If nothing was taking care of all the dung, we'd be neck deep in it.
Is all this a result of lack of technology or a lack of will or leadership?Let me point out that we are here at somewhere between TL 7.75 and 8.25 and we don't have the foggiest idea of how to colonize another world, build self-sustaining O'Neil cylinders at the Trojan Points or even how to get our asses off Earth in an affordable enough way to make it common.
We have dreams. We have theories. We have conjecture. But we have absolutely NO concrete nuts-and-bolts proof that any of that stuff in 'The Martian' will actually work. It works in theory. The math works out. But math is not experience, nor is it engineering. The math worked out for Chaffee, Grissom, and White aboard Apollo 1. And it worked out for the crew of Challenger. The math says it's possible, but only because we don't have the engineering experience to know what real problems are going to be.
And to put a very sharp point on it, even if the Artemis Project works without a hitch, it's still not a self sustaining colony. It will be, essentially, an 'oil rig on the Moon', utterly dependent on monthly supply runs by spacecraft we haven't gotten to work yet. Skylab was a failed cometary display, Mir lasted longer but also fell to Earth. And the so-called International Space Station is a bunch laboratory soup cans held in place by girders. It's not much more advanced that Skylab was. NASA is bogged down by its own bureaucracy, Space-X is a bust, the Space Force is joke and I honestly don't see a self-sustaining colony being a success in my lifetime.
Don't get me wrong here. I'd LOVE to see off-Earth settlement in my lifetime. But 'hope is not a strategy'. Hope is about as useful in the real world as 'thoughts and prayers'. Real, honest work needs to happen where the sole agenda is getting Mankind off Earth. And nobody is doing that work yet. All the interested parties are too married to their own agendas to get any real progress made.
I've posted this meme more than once here, but it is particularly apt for this conversation.

We suspect that there are raw materials in the solor system. Chemical spectrography says the elements are present. But we have zero /zilch /bubkus /nada /nichts /nil/ no idea how those resources could be obtained. We speculate that it's possible that they could be harvested, but that is solidly in the realm of science fiction and not even speculative fact as yet.Is all this a result of lack of technology or a lack of will or leadership?
We don't need to these things at the moment and the tragedy of the commons indicates that if I personally don't need it I won't do anything about it (including voting for leaders that will).
We know there are vast reserves of raw materials in space, but it requires a significant investment to realise (but that will repay the investment). Once we do the scarcity of earth based resources will diminish and their value will drop. Anyone with investments in terrestrial resources will lose out and therefore will block any programme to exploit. Those with such investments will own politicians.
Traveller posits a non-elected emperor. They do whatever the hell they want.
First we need to decide we want to do it. Then decide how much we want to pay to do it and what other constraints apply. Then we can start deciding on how we are going to do it within those constraints.We suspect that there are raw materials in the solor system. Chemical spectrography says the elements are present. But we have zero /zilch /bubkus /nada /nichts /nil/ no idea how those resources could be obtained. We speculate that it's possible that they could be harvested, but that is solidly in the realm of science fiction and not even speculative fact as yet.
First we have to design and field a life support system that will last multiple years in space without resupply.
Then we have to figure out a way to get off Earth using methods that will not further pollute the environment.
Then we have to design and test techniques to build a long term habitat off Earth.
And I suspect there's another 75 or 100 things I haven't thought of that must be dealt with before we can even begin to thing about asteroid mining and scooping petrochemicals out of Jupiter.
Didn't the Elysium ring have a transparent roof? It's not relying on the rotation to retain the atmosphere. So could be of any size.
It does indeed seem to be a huge Stanford Torus.
No. In order to get anything near 1 atmosphere at the surface, that thing would have to spin fast enough to crush anyone at the surface, and you will still have diffusion into space. It is just too small.![]()
Atmospheric retention.
I think we can all agree that atmospheric force fields are above the TL capacity of a non-FTL capable EarthI don't see a ceiling, glass or otherwise, and if gravity isn't enough, they'll have to create a virtual one.
It's connected with a number of related issues.
Fusion reactors provide cheap energy, robotics and artificial intelligence will remove the need for most human labour.
Add in life expectancy and births, and it becomes a question of human rights and privileges.
You can feed everyone, you can house everyone, and you can keep everyone entertained.
Could be, the issue resolves itself.
Behavioral sink is a term invented by ethologist John B. Calhoun to describe a collapse in behavior that can result from overpopulation. The term and concept derive from a series of over-population experiments Calhoun conducted on Norway rats between 1958 and 1962.[1] In the experiments, Calhoun and his researchers created a series of "rat utopias"[2] – enclosed spaces where rats were given unlimited access to food and water, enabling unfettered population growth. Calhoun coined the term behavioral sink[3] in a February 1, 1962, Scientific American article titled "Population Density and Social Pathology".[4] He would later perform similar experiments on mice from 1968 to 1972.[5]
Calhoun's work became used as an animal model of societal collapse, and his study has become a touchstone of urban sociology and psychology in general.[6]
