Gave this topic more thought and wondered if it would be neat tech to be able to construct a ringworld(s) in the influence range of your capital planet.
As for repairing ringworlds, I made a mini mod for myself that let me terraform broken rings into their repaired counterparts and then the nice versions into habitable ringworlds. I then had three 12x25 ringworlds to play with. It is not balanced, but it is fun to rp. I made it cost a shit ton of minerals, energy, 2 terraform liquids, 2 terraform gasses, and 5 living metal resources, as well as a shit ton of time to do. It is just really cool from an rp stand point. Also I made techs to allow you to build the fallen empire resource buildings on gaia and ringworlds.
Not gonna lie, that sounds like an awesome way to make Gaia worlds worth entire wars over. Imbalanced as it is, it puts extreme value and makes the owner empire a threat.
Yes, it does make them quite valuable. My single 12 planet ringworld makes me so much stuff. I have it broken down as 4 tech, 3 minerals, and 5 energy. I make about 200+ of each research, 2000 energy and about 1900 minerals a month. This is just from my ringworld start system. Not to mention the 3 mothers I got off a fallen empire.
Well, actually it is radius * 2 pi * width* height* density, so it is more close to 7.5 *10^22 kg for a 10 km wide ring.

Technically, there is a way to repair a ringworld, if you not in iron mode. pc_ringworld_habitable, pc_ringworld_tech, pc_ringworld_seam.
People calculating how much steel you'd need to build a ringworld are missing the very serious issue that no known materials are strong enough to build a ringworld out of (within a reasonable mass budget, you could do it with a thousand Jupiter masses of Tungsten and let the gravitational attraction of the tungsten to the star counter the centripetal force, but the point of a ringworld is to maximise surface area per atomic mass.)
In order to actually build a ringworld that won't fly apart under spin you need tensile strength close to the strong nuclear force*, so it doesn't matter what matter you start with you're reprocessing it from at least the atomic scale up (and probably deeper) into exotic matter anyway.
Most likely you're dismantling the inner planets of your system and probably mass reducing the star itself (prolonging its lifespan as a bonus), leaving outer gas giants as they're convenient meteorite hoovers, and rebuilding everything at the subatomic level into your new building material.
* And once you have that, well, god help your enemies in a fight because your ship hulls are functionally impervious to lesser matter and can be a near perfect mirror to all forms of energy, see: Three Body series.

They took two liters from a 55kg individual...?! That's extreme, if not outright irresponsible.

Yeah I second this. That would amount to about 40% of his total blood volume. I daresay he would not be able to walk out of the clinic without fainting if this was true.

A pint is slightly more then 2 liters, btw.
What I find very frustrating is how this is the second post in this thread I made where people disagreed with it and then made a retort that very clearly shows they didn't both to do the math themselves or make a simple google search. If you want to respectfully disagree with me that is fine but don't disagree because of unhelpful garbage like this. Anyone who read and believed your posts now has misinformation that is moving them further from knowledge, the exact opposite of what respectful conversation attempts to achieve.

Look, I'm sorry but you're the one messing up your units. An average sized human has about 5 liters of blood and a regular blood donation is about 0,5 liters. A pint is 0,5L, you divided by 0,5 instead of 2 at some point or something.
Okay then I made a mistake. I just overreacted because last time in this thread people didn't remotely try to do the math and still acted condescending.
The mistake was that in the original I said liters when I actually gave the number of pints. Please consider the point adjusted.

You know... several astronauts lost their lives for this very mistake.
Aaaaand I just gave an assist to bring back the discussion where it should stay: in space

Yes, originally it was a comparison to illustrate a point about space.
Even if we ignore the vast quantities of metal that exist outside of gravity wells such as asteroid belts, 2% of the mass of a planet isn't an insanely large amount of matter. A megaproject to be sure but it's on the same scale as giving a double red blood donation is for a human. So one would not need to mine a planet to collapse in order to build a ringworld with a mass of 2% of a planet. Super advanced mining techniques, yes. Tear the planet apart, no.

Utilizing 2% of a planets mass for a megaproject the same ballpark as a double blood donation? Are you serious? I want some of whatever it is you're smoking bro.
Besides you could never build a stable ringworld using just 2% of earths mass. It is nowhere near enough. The people at PBS spacetime have done some maths/physics on it, go check it out.
1 kg from a 45 kg person is about 2%...
Surely you can give me a reason instead of appealing to an abstract and unspecific argument somewhere.
