I was very clearly talking about the dimensions of the proposed ringworld. And illustrating how thin and stretched out it would be. You don't think that plays a role in its structural integrity? We are most certainly not building wooden bridges on earth here...

Show me some math, please.

I like how all of u are trying to explain this during real-world maths. I really do. but tbh this really doesn't matter. here's a couple points I believe explain why it should be possible to build/restore a ringworld.

1: its a video game, we cant logic everything in it.
2: the game kind of explains this absence of real world science using living metal. this is a super strong self replicating material that actually states "may have had something to do with their advanced construction". this would eliminate the need for a planets worth of materials. here's my thinking.

this is a self replicating material meaning technically u already have an infinite amount of this material. also, if u can use one of this and have enough to upgrade thousands of starships with the material then we must have more than a planets worth of the stuff with just 1 living metal. in the save I'm playing atm I have 14. this should be more than enough to form the base of the ring world. this could then be supplemented with large quantity of minerals. then, using large amounts of energy and minerals could then terraform each section of the ringworld into the 25 gaia. then the ringworld could spawn a lot of living metal as well. and if u think, but isn't that mean I'm mining the ring under me, its self replicating so its growing up through the base of the ringworld.

this is just my thinking, disagree if u feel like it.

Show me some math, please.
Diameter of a 1 AU radius circle = 300.000.000 km
Diameter of a sportsarena 0.150 km
Ratio between the two: 2.000.000.000
10km width devided by 2.000.000.000 = 0.005mm
and then 1km depth is 0.0005mm
Even thinner than I first estimated, the width is already beyond human sight.

Love the science posts in this topic.
Most likely humans won't build a ring world.
Build one from scratch? No.
Repair one already existing?
Yeah.
Build a smaller scale not a perfect one as a giant space station like the citadel from mass effect?
Yes.

In irl provided we make it to space permanently 1 and/or 2 will happen:
1.Humans will become robots/cyborgs/gene modded to live everywhere.

2.humans will make a fuck ton of "gaia" worlds and close_enough.jpg planets to live on via terraforming over a long period of time and by many different methods.


But on topic:

Im for at least a repair of ringworld sections.

You could balance it by requiring almost all of the technology tree finished and a few repatables.
And also making it 90% and not 100% living to reflect that, while we have the basic ring tech down for the most part to live in, we dunno how to build one on our own,and the small nuances that make it from good to perfect.
Also you could have the difference between FUBAR section that will take ages and a destroyed/damaged ring section that is fixer upper and only slightly damaged/disabled which would be a lot faster.

I do like that ur trying to show how our ringworlds are not perfect, but if u think bout it, by the time youve finished what ur saying should be the prerequisite amount of technology in order to build a ringworld, u already have all those little techs that give u all the habitability bonuses making this a pointless gesture.

Maybe there could be some unique events about maintaining the ringworld or of some faults that develop over time. And if they did give u the ability to build/ repair a ringworld then the ringworld in question should follow the same visual guidelines as each species unique ship texture. To give it a difference between the old ones and the new, and to give them a piece of personality

Given we're dealing with Ringworlds Classic here, I think it would be interesting if there was an event re: colonized broken ringworlds where it was in danger of slipping into the sun.

(Also they should add the sunshades in on a closer orbit)

Super late to the discussion, but the main problem with the proposed ringworld is that the surface area is not substantially larger than earth's. (20x) But the layout is substantially less convenient. The longest path along the ring between the two most distant points is going to be ~500 million km. Whereas on earth, the longest path between two points is roughly 12,000 km.

A sphere with the same surface area as the proposed ringworld would only have a radius of ~27,000 km and a longest path of 85,000 km. (~5000 times shorter than the ringworld)

Hi, sorry if i am too late for the discussion.
If the ring world is in orbit there is no tensile strength into play, as gravity is applied over a volume and not on a surface, the main problem as someone else pointed out is that in order to obtain an artificial gravity of 1 G you need to spin up the ring above it's stationary orbital velocity, now the ring structure is under stress, likewise if you ever wanted to keep the ring world still in space (not orbiting) it would collapse on itself under compression.

future tech ignores your logic.

there is a mod I like to use wherein you obtain late game tech which allows you to terraform damaged ringworlds into fully active planets, albeit without any special resources. Not only that, but the mod lets you research building all the super powerful special buildings, which can ONLY be built on ringworlds (and on your homeworld, but that's beside the point). Here it is if you want to use it; I would absolutely love something like this in the vanilla game.
