Its a space elevator
active support is using the momentum of high-speed whatever to offset gravity or spinning two fast or any other force to make a material stronger then is effectively possible. just look into Issac Arthur.

Without the ultra strong materials.
And with a massive energy cost
That depends massively on your sustaining loop efficiency.
just use fusion or black holes
edit i am anti-dyson sphere, its dumb, make a dyson swarm. you still get everything, plus aimable Nicoll-Dyson beams and Shakadov thrusters.
or nuclear. Fusion + nuclear + space solar power. Pretty much the future here.
IF we dont get fusion working then its gonna be nuclear + space solar power.
Dyson spheres can be used to generate solar power, they can be used as artificial planets, and we can move entire stars. Now tell me their not useful.
Dyson swarms are better cause they actually get to use the power (as opposed to using all of it for a tive support), and take less than a murcuryâs worth of mass for more living space.

I still find Stellar engines to be really cool, I posted about it a while back
Did you mean stellar engines, rather than Stellaris (the game)?
Yeah, my autocorrect is horrible on my phone
-_-
Soooo i dont see this said anywhere here but one super advanced branch of theoretical techs is metric engineering, like manipulating space-time itself.
For example the warp bubbles from warp drive.
Those warp bubbles can be larger on the inside than on the outside by enclosing more space in it. This can make spacecrafts almost imposssible to detect and would make a terrific weapon.

one thing i thought of (it may be a stupid thought ngl, and ive done no prior research, i just want to write it down here so i dont forget) is what if a civilization used solar wind in order to generate mass amounts of electricity? I heard solar wind is made up of electrically charged particles going at millions of miles an hour sooâŚ
A black hole bomb. A device that explodes the normal way and then creates a black hole.
Before I explain how it works, lets talk about dark matter. Unlike baryonic matter, it doesnât interact with itself, if it comes across another dark matter particle, it just passes through it. Thats why while galaxies and solar systems collapse into a disc shape spinning in one direction because all the matter going in another direction would collide with the disc and start moving in the same direction (the direction was determined by which direction and which plane had the most matter going that way at the start, even if thats a slight majority), the region with more dark matter is spherical around those solar systems and galaxys, like an oort cloud all the way to the center.
How this bomb works is that its shape doesnât matter, it looks like a random object. You create it and place inside the space station you want to damage which is in a solar system or another gravity well. It has the ability to interact with dark matter. So suddenly all these dark matter particles, roughly equal from each direction start hitting that object. The object heats and releases photons. It is an explosion but no way to stop the detonation, as if the energy for it is being created out of nothing. If the space station survives this (and starts using it as a power source), they would slowly start to measure the gravity being increased. As dark matter particles start to accumilate around the object, their gravity start to pull other dark matter particles (and there is no outward push like in stars, dark matter particles either orbit the object or bounce on it, getting closer to it) (which is 5 times the baryonic mass in that solar system) and after a point it collapses into a black hole.
How would some species obtain dark matter and transport it before it creates black hole?

Dark matter may not exist, we just got the gravity equation wrong. Gravity has something to do with gluon attraction though, so maybe you can incorporate that?
Make a box out of the material that interacts with dark matter, fill it with dense dark matter and escape from there in hyperspace
Then a black hole bomb canât be made the way I presented it.
Well your bomb wouldve worked by accretion and usually accretion takes millions of years to make one planet let alone a black holeâŚsooooo.
