Some Fallen Empires have them as their homeworlds, sometimes you can find an abandoned one randomly in the Galaxy.

I'm only new myself but I love the fallen empires and know a bit about ringworlds. they tend to be found in one of the fallen empire civilisations and have names like beacon of something (at least all the ones ive seen have) if u find a fallen empire and they have only one or two world than its more than likely that they are ringworlds, although a fallen empire may still have a few planets and a ringworld I'm not sure.

Instead of being Gaia, though, it could be built to match your preference of planet type.

You can keep yer ring worlds, what I would love to have to fight over is a star forge! The SWKOTOR fans among us will know what I'm talking about.

Since we don't have white dwarves in game (although perhaps we should???) maybe it could be built over a neutron or pulsar star.

Edit: forgot a word.

Suppose you have a ringworld made out of solid steel, 1km thick, 10km wide and going around the sun at the orbit of the earth. The mass of this would be 3.78330333 × 10^22 kilograms. The mass of the earth is 5.972 × 10^24 kg. The ringworld would thus be less then 1% of the mass of the earth.

It's still a buttload of material. However you wouldn't need to break up all the planets to make it.
The earth is roughly 35% iron and 99% of that is in the core so at best you got about .4% the mass of the earth in iron. Steel is iron plus carbon (which is about 2% the mass of the steel). So based off your numbers we'd need 3.70763726e22kg iron and 7.566607e20kg carbon. Unfortunately for you, without getting into the core (and thus literally tearing the planet apart) Earth "only" has 2.0902e22kg of accessible iron (assuming it is all in the crust and all readily mineable and there's no losses in the process).

The total biomass of the Earth is 4 trillion tonnes (4x10^12) of carbon, well short of your needed 7.6e20kg. So not only would you need to tear the entire planet apart to get to the irony, irony core but you'd also need to extract the carbon of 200 million times all the life on the planet Earth (which many people would find unethical). Of course, you can also add coal and oil to this but given that those are limited to the top of the crust and are produced in millions of tonnes, I doubt they'll really impact this calculation in the long run.

And all of this, all of this above assumes that it just magically turns into a giant ring. No forges to be fired, no parts to be blasted off into orbit, no billions upon billions of workers to assemble it. Just the steel of the ring itself. No furnishings. No extras.

In short, no - you'd actually have to tear entire planets apart to build your ring.

-----

Now, I actually came here to ask if this might even be within the reach of modding. Last I checked there was a mod that would spawn a ring world around a star near a system if you selected a rather intense project. Would it be possible to despawn a broken section of ring and replace it with a working section of ring ready for colonization?

Ring worlds are made of a special type of metal that's alive its part of how the living portion of the station was formed.

That's fine, but that wasn't one of the assumptions I was inheriting to dispute the assumption that one doesn't need to near a planet apart to build a ring world.

]So not only would you need to tear the entire planet apart to get to the irony, irony core


It reminds me of the last time I gave blood. I was donating two liters pints (I do double reds). That is 2% of the mass of my body (I'm on the smaller side, about 125 pounds). I showed up expecting that they would just stick a needle in my skin and extract the blood. But it turns out that if you extract 1% or more of the volume of something you have to tear it apart. So they actually had to rend me into pieces limb from limb and then go sifting through the chunks to get at my blood. Gee, that was painful!

So they actually had to rend me into pieces limb from limb and then go sifting through the chunks to get at my blood. Gee, that was painful!
False comparison - blood is separated from the rest of your body and fluid so it is easy to remove through a needle. Iron (except in the core/lower mantel) is solid and in an ore form. It needs to be mined out, purified, and then smithed. And it's in semi-randomly distributed veins, rather than in the easily predictable human venous system. So as you have to dig up a lot more material than the usable iron ore and even from that you only get a fraction of that in usable iron (Iron ores range from 70% iron on the high end to 50% iron on the low end).

And like I said, my assumptions are already favorable to you (including your volume, which another user pointed out might be considered "small" for normal sci-fi purposes) - that there is zero loss in removal, that all the iron not in the core is in the crust and is reachable by miners. Neither of those are true. Iron is distributed through the mantel as well or exists far below the surface of the Earth where we can't easily imagine how effective far-future mining would be. Plus ores are a limited resource, with the Worldwatch institute predicting a dramatic decrease in ore production by the end of the XXI Century.

You would, in the end, tear up the planet trying to get to it all, or more likely find a slightly less useful and uninhabited planet and blow it up for easy consumption. And that has its own problems because Earth is an outlier with its iron core. For example, Mars lacks the large, mostly iron, core we have (hence its weak, hardly protective magnetic field). So yields from Mars-like planets will be much lower and we'll likely need to use several of them.

And that's just iron. Steel isn't iron. It's iron and carbon. What's likely is that we make some machine that can convert the carbon in the air and in the lithosphere into just plain carbon, but even those would require ridiculous amounts of resources because we aren't even considering, at all, that all these processes (mining, smithing, carbon extraction, launching into orbit, welding, furnishing, &c) all also use huge amounts of resources in the form of (for example) food, power, and other materials. We are only talking about the steel used as the backbone of the ring. A commonly given example in the aerospace industry is that if bricks magically became solid gold when taken into space, you would very quickly go bankrupt loading bricks onto a rocket and launching it into space. Current-ish estimates are about $22,000 by kg to get to LEO, which is no where near enough energy to get it to the ring.

Or, more likely, we'd use the resources of many, scattered planets, to more evenly distribute the damage and minimize the local effects. But that will increase the resources put into moving all that iron around. You'd need almost entire planets made of rocket fuel, luckily, though, those exist - planets like Jupiter and "useless" stars could be "mined" for their hydrogen, other worlds could be tapped into to provide oxygen as another important part of rocket fuel. Now, we might also have invented a better propulsion system by the time we're building a giant ring but we're getting a tad off track...

So a better example would be that we need to extract 1% of your mass via your bones, but not just any bone mass, but randomly scattered bits of your bone mass which we will crush up and extract the calcium from (while discarding the waste - bones are 50% mineral and of that 64% is calcium) in order to make packs of chalk. Sure, your mass will hardly decrease, but I think that after enough extractions you won't be in as good of shape as you started. There are certainly easier ways to get less than two-fifths a pound of calcium. (Interesting to note, but not the scenario I am presenting - 1% of your weight in calcium would essentially require the destruction of your entire skeletal system.)

You think that maybe just maybe when I referred to the amount of iron in the core I was referring to core mining? I mean not to spoil your illusion or anything but this is a science fiction setting with energy shields and faster then light technology. The technology is just a little more advanced.

You aren't making favorable assumptions, you are reading so far off the page to get things I never said that it's ridiculous.

Okay, but that's what we're saying. If "technology so advanced it is essentially magic to those of us stuck in the 21st century" is at play, then yes - we can say whatever we want and it won't be far from "true" and you're 100% "correct". But from a hard sci-fi or scientific view-point, you are grossly ignoring major components of the construction of a solar-system sized project like this, which would provide interesting balance to the game.

For example, you can build a ring world, but you need to destroy several planets to do it. The bigger and more useful the planet the more resources it gives. Is that 24-tile gaia planet worth it? What about that 8-tile desert world you were using as a "nature preserve" for those feudalistic scorpion people? Smaller planets and asteroids need to be cleared from the solar system as well, to ensure the safety of the ring, one of those that needs clearing is a tomb world looked over by a fallen empire. Do you "clean it up" and risk their wrath when you insult both their pride and their ethos? Or do you move to another, less favorable location in order to maintain the peace?

this is why I said they should be built only in asteroid systems in my comment on the modders page. these astroids (we can assume) would be full of usable material. and remember, lots of the world sections of the ring wont be solid metal, it'll have planet sized amounts of ground there. so even the "unusable" material in the mining process will have a process. filler for the planet sections. and inspect the ring up close. the planet sections are think granted, but the joiners between are nothing more than massive pipes between the sections. this means that these rings could be considerably thinner than we believe. also, by the point of making this, we can assume the player has a very large intergalactic empire going on, with massive starfleets and half a galaxy under their control. so with all that we can also assume that the literally insane quantities and access to materials would make this feasible. and away from logic here, the construction ships in this game can take 90 minerals and build a fully crewed mining outpost. is it such a far stretch that they can get 20k minerals and build an orbit sized ring with space for several planet sized areas of land.
